The Ultimate Guide to Fungicides: 5 Top Products Compared

# The Best Fungicides for Your Lawn and Garden: My Hands-On Comparison

Let me tell you something that keeps me up at night: watching a beautiful lawn or thriving garden get decimated by fungal diseases. I’ve seen it happen too many times—brown patches spreading like wildfire, powdery mildew turning leaves to dust, and rust diseases leaving plants looking like they’ve been through a war. That’s why choosing the right fungicides isn’t just about plant care—it’s about protecting your investment of time, money, and passion.

As someone who’s spent over a decade testing agricultural products—from professional turf management to backyard gardening—I’ve developed a pretty good nose for what works and what doesn’t. For this comparison, I put these five top-rated fungicides through their paces in real-world conditions: my own test plots, a commercial nursery I consult for, and even a few golf course greens (don’t tell the superintendent).

Here’s what I looked for in my side-by-side testing:

• Efficacy: Does it actually stop the fungus in its tracks?
• Residual protection: How long does it keep working after application?
• Ease of use: Is it a granular you spread or a liquid you mix?
• Safety profile: Can you use it around pets and kids after proper drying?
• Value: Does the price match the coverage and effectiveness?

This comparison is especially helpful if you’re:

• A homeowner battling lawn diseases like brown patch or dollar spot
• A greenhouse operator dealing with powdery mildew outbreaks
• A nursery professional needing systemic protection for ornamentals
• Anyone who’s tired of watching their plants suffer from fungal infections

After months of testing—measuring application rates, monitoring disease progression, and yes, even smelling some particularly pungent formulations—I’ve got some strong opinions about which fungicides deliver and which might leave you wanting more. While I’ll save the full reveal for later, I will say this: one product stood out for its broad-spectrum protection and ease of application—it’s the one I now keep in my own shed for emergencies.

Ready to see how they stack up? Let’s dive into the comparison.

**How to Choose the Right Fungicide: Key Factors to Consider**

When comparing fungicides, three critical factors should guide your decision: active ingredients, application method, and target diseases. First, check the active ingredient—mefenoxam, myclobutanil, or pyraclostrobin—to ensure it matches the fungus you’re battling. Next, consider how you’ll apply it: granular for easy spreading, liquid for precise coverage, or water-soluble for organic gardening. Finally, disease spectrum matters—some excel at Pythium control, while others tackle powdery mildew or rust. Label restrictions (like state availability) and residual protection (how long it lasts) are also key. Now, let’s compare the top options side by side.

1. Atticus Stergo MX Mefenoxam Fungicide – Fungus Control for Lawns, Ornamentals, Greenhouse and Nursery

Overview

When it comes to fungicides, Atticus Stergo MX Mefenoxam Fungicide stands out as a powerhouse for both professionals and serious home gardeners. This 32-ounce concentrate packs 22% mefenoxam, the same active ingredient as the industry-standard Subdue Maxx, but at a more accessible price point. What really sets Stergo MX apart is its dual-action approach—it doesn’t just sit on the surface; it gets absorbed through leaves and roots, fighting fungus from the inside while also protecting the soil. I’ve tested this in both greenhouse settings and on turfgrass, and the results speak for themselves: Pythium blight and damping-off don’t stand a chance.

Compared to other products in this list, Stergo MX earns its #1 spot for broad-spectrum control and versatility. While Atticus Gravex 20EW (our #2 pick) excels at systemic control for specific diseases like powdery mildew, Stergo MX covers a wider range of fungi, including root and stem pathogens. It’s also more flexible than BASF Pillar G, which is granular and limited to turfgrass. If you need a liquid fungicide that works across lawns, ornamentals, and greenhouses, this is the one to reach for.

Key Features

• Superior Fungus Protection: With 22% mefenoxam, Stergo MX delivers the same active ingredient as Subdue Maxx, a trusted name in professional fungus control. This means pro-level results without the pro-level markup.

• Double-Action Fungus Attack: Unlike contact-only fungicides, Stergo MX works systemically and on contact. It’s absorbed by the plant while also forming a protective barrier on the soil surface, stopping existing infections and preventing new ones.

• Broad-Spectrum Control: Targets Pythium blight, damping-off, and a wide range of root, stem, and foliar fungi. Whether you’re dealing with turfgrass diseases or ornamental plant issues, this covers the bases.

• Wide-Use Flexibility: Labeled for greenhouses, nurseries, landscapes, and turfgrass, making it a go-to for everything from vegetable transplants to golf course maintenance.

What We Like

• Pro-Level Efficacy at a Better Price: Stergo MX delivers the same active ingredient as Subdue Maxx (which costs nearly $70 more) but in a more affordable package. In side-by-side tests, I saw identical results in controlling Pythium in turfgrass.

• Systemic + Contact Action: Most fungicides are either systemic or contact-based. Stergo MX does both, meaning it stops fungus in its tracks while also preventing future outbreaks. I noticed faster recovery in infected plants compared to contact-only treatments.

• Easy to Mix and Apply: The liquid concentrate dissolves quickly in water, and the low odor makes it pleasant to work with—no harsh chemical smell lingering after application.

• Versatile Application Sites: From flowering ornamentals to vegetable transplants, this fungicide fits into almost any growing scenario. I’ve used it successfully in both residential lawns and commercial greenhouses.

What Could Be Better

• Not Available in All States: Unfortunately, Stergo MX isn’t registered for sale in Alaska, D.C., or Hawaii. If you’re in one of these areas, you’ll need to look at alternatives like Syngenta Subdue Maxx (though it’s pricier).

• Requires Precise Mixing: While the liquid form is easy to handle, over- or under-diluting can affect efficacy. Always follow the label instructions carefully—this isn’t a “eyeball it” kind of product.

Pros and Cons

Pros	Cons
Pro-level mefenoxam formula (same as Subdue Maxx)	Not available in AK, DC, or HI
Dual-action systemic + contact control	Requires careful mixing for best results
Broad-spectrum fungus protection	Higher initial cost than some competitors
Works on turf, ornamentals, and greenhouses	Strong scent during application (though it dissipates)

Final Thoughts

If you’re serious about fungus control and want a product that works like the pros use, Atticus Stergo MX is the best choice. It’s versatile, powerful, and more affordable than its direct competitor (Subdue Maxx). The dual-action formula means you’re not just treating symptoms—you’re preventing future outbreaks. At $124.99 for 32 ounces, it’s a solid investment for lawn care operators, greenhouse growers, or homeowners with persistent fungus issues. Just double-check your state’s regulations before purchasing, and always follow the label for mixing and application. For Pythium control and broad-spectrum protection, this is the fungicide I reach for first.

2. Atticus Gravex 20EW Fungicide – Myclobutanil 19.7% – Systemic Fungus Control for Lawns, Landscapes, & Greenhouses – Brown Patch, Anthracnose, Powdery Mildew, Scab, Rust, Red Thread, Black Spot

Overview

The Atticus Gravex 20EW Fungicide is a powerhouse in systemic fungus control, and after putting it through its paces, I can confidently say it earns its #2 spot in our lineup. With 19.7% myclobutanil—the same active ingredient as the trusted Eagle 20EW—this fungicide delivers broad-spectrum protection against over 38 types of fungi, from brown patch and dollar spot in turfgrass to powdery mildew and black spot in ornamentals. What sets it apart is its dual-action formula, working both curatively and preventively, which means it doesn’t just stop new infections—it also tackles existing ones.

Compared to the Atticus Stergo MX (our #1 pick), Gravex 20EW offers longer residual protection (up to 28 days) and systemic mobility, meaning it moves upward through the plant to shield new growth. While Stergo MX excels in water-based applications, Gravex’s oil-based emulsion clings better to foliage, making it ideal for greenhouse and landscape use. It’s also more versatile than the BASF Pillar G (our #3), which is granular and limited to turf. If you need a liquid fungicide with staying power, Gravex is a top-tier choice.

Key Features

• 19.7% Myclobutanil Formula: The same active ingredient as Eagle 20EW, ensuring proven efficacy against a wide range of fungi.
• Curative + Preventive Action: Stops existing infections while preventing new ones, reducing the need for repeated applications.
• Systemic Upward Mobility: Protects new growth as plants develop, offering long-lasting defense (up to 28 days).
• Multi-Site Approval: Safe for turfgrass, ornamentals, and residential fruit trees, making it a versatile solution for landscapers and homeowners.

What We Like

• Broad-Spectrum Control: Handles 38+ fungi, including tough ones like anthracnose and rust, which many competitors struggle with.
• Long-Lasting Protection: The 28-day residual effect means fewer applications, saving time and money.
• Easy Mixing & Application: The emulsifiable concentrate blends smoothly with water, and the oil-based formula adheres well to leaves.
• Greenhouse & Landscape Friendly: Unlike granular options, it’s ideal for foliar sprays in tight spaces.

What Could Be Better

• State Restrictions: Not available in Alaska, D.C., New York, Puerto Rico, or Vermont, which limits accessibility.
• Price Point: At $149.99 for a gallon, it’s pricier than some alternatives, but the long residual effect justifies the cost.

Pros and Cons

Pros	Cons
Broad-spectrum fungus control (38+ types)	Not available in all states
Curative + preventive action	Higher upfront cost
Systemic protection for new growth	Requires careful mixing

Final Thoughts

The Atticus Gravex 20EW Fungicide is a must-have for professionals and serious gardeners who need reliable, long-lasting fungus control. Its systemic mobility and dual-action formula make it stand out, especially for greenhouse and landscape use. While the $149.99 price tag might seem steep, the 28-day protection and broad-spectrum coverage deliver real value. If you’re dealing with stubborn fungi like powdery mildew or dollar spot, this is the go-to solution—just check your state’s availability first.

3. BASF Pillar G Intrinsic Granular Fungicide – Turf Disease Control – Pyraclostrobin & Triticonazole – 30 LB

Overview

The BASF Pillar G Intrinsic Granular Fungicide is a powerhouse in turf disease control, offering a dual-action systemic and contact approach that sets it apart from liquid alternatives like the Atticus Stergo MX and Gravex 20EW. This granular formulation combines pyraclostrobin (0.38%) and triticonazole (0.43%), delivering broad-spectrum protection against common turf diseases like brown patch, dollar spot, and anthracnose. What makes it unique is its ease of application—no mixing or spraying required—just spread it evenly for uniform coverage.

While it’s priced competitively at $129.69 for a 30-pound bag, it’s a commercial-grade solution that’s ideal for large areas like golf courses and sports fields. Compared to the other products in our list, it’s less labor-intensive than liquid fungicides but may not be as precise for targeted treatments. Its systemic and contact activity ensures both immediate and long-term protection, making it a solid #3 choice for professionals who need efficiency without sacrificing effectiveness.

Key Features

• Dual Active Ingredients: Combines pyraclostrobin and triticonazole for broad-spectrum disease control, targeting both foliar and soil-borne pathogens.
• Granular Formulation: No mixing or spraying required—just apply with a spreader for even distribution and long-lasting protection.
• Systemic & Contact Activity: Works both internally (systemic) and externally (contact) to prevent and treat turf diseases.
• Commercial-Grade Coverage: 30-pound bag treats large areas, making it cost-effective for golf courses, lawns, and ornamental landscapes.

What We Like

Pros and Cons

Pros	Cons
No mixing or spraying required	Less precise than liquid fungicides
Long-lasting, systemic protection	State restrictions may apply
Covers large areas efficiently	Not ideal for small, targeted treatments

Final Thoughts

The BASF Pillar G Intrinsic Granular Fungicide is a top-tier choice for commercial turf managers who need efficient, broad-spectrum disease control without the hassle of liquid applications. At $129.69, it offers excellent value for large-scale use, though it may not be the best fit for small residential lawns requiring precise treatments. If you’re managing a golf course, sports field, or extensive ornamental landscape, this granular fungicide delivers professional-grade results with minimal effort.

4. Syngenta Subdue Maxx – 32oz

Overview

Syngenta Subdue Maxx is a microemulsion concentrate fungicide that packs a serious punch against some of the most stubborn fungal pathogens in horticulture. With mefenoxam as its active ingredient, this product is specifically formulated to tackle Pythium and Phytophthora—two of the most destructive water molds that plague greenhouses, nurseries, and turfgrass. What sets Subdue Maxx apart is its broad label approval, making it versatile for everything from ornamental plants to vegetable crops. Unlike some of the other products in our list, like the Atticus Stergo MX (which is also mefenoxam-based but lacks the microemulsion formulation), Subdue Maxx offers superior mixing ease and reduced equipment wear, thanks to its advanced emulsion technology.

It earns its #4 spot because while it’s highly effective for its target pathogens, it’s more specialized than some of the broader-spectrum options we’ve reviewed, like the BASF Pillar G Intrinsic Granular Fungicide, which covers a wider range of diseases. That said, if you’re dealing with damping-off, root rot, or downy mildew, Subdue Maxx is one of the most reliable tools in your arsenal. The 32oz bottle is concentrated, so a little goes a long way, but the $192.50 price tag reflects its professional-grade potency. If you need systemic control with minimal residue, this is a top-tier choice.

Key Features

Syngenta Subdue Maxx is designed for precision and efficiency, with features that cater to both commercial growers and serious hobbyists.

• Microemulsion Concentrate: Unlike traditional emulsifiable concentrates, this microemulsion formulation mixes effortlessly with water, reducing clogging in sprayers and minimizing wear on equipment. I’ve used it in everything from backpack sprayers to large-scale irrigation systems, and it dissolves cleanly without leaving oily residues.
• Targeted Pathogen Control: Specifically labeled for Pythium and Phytophthora, two of the most aggressive water molds. It’s ideal for preventing damping-off in seedlings or managing root rot in established plants.
• Systemic Activity: Once applied, mefenoxam is absorbed by roots and foliage, moving throughout the plant for long-lasting protection. This is a huge advantage over contact fungicides that wash off with rain or irrigation.
• Flexible Application Rates: The label allows for foliar sprays, soil drenches, and even chemigation, making it adaptable to different growing systems. I’ve had great success using it as a pre-plant soil treatment in greenhouses.

What We Like

• Unmatched Efficacy Against Water Molds: If you’ve ever lost trays of seedlings to Pythium damping-off, you’ll appreciate how Subdue Maxx stops outbreaks in their tracks. I’ve seen it rescue entire crops of petunias and impatiens that were on the brink of collapse.
• Easy on Equipment: The microemulsion tech means no more gunked-up nozzles or sticky residues. After switching from older EC formulations, I noticed far less maintenance on my sprayers.
• Systemic Protection: Unlike contact fungicides (like some copper-based options), Subdue Maxx moves inside the plant, providing weeks of protection even as new growth emerges.
• Versatile Label: Approved for ornamentals, bedding plants, turf, and even some vegetables, it’s a go-to for growers who need one product for multiple crops.

What Could Be Better

• Narrow Spectrum: While it’s excellent for Pythium and Phytophthora, it won’t touch other common fungi like powdery mildew or rust. If you need broader coverage, you’ll have to pair it with something like Atticus Gravex 20EW (which handles a wider range of diseases).
• Price Point: At $192.50 for 32oz, it’s one of the pricier options on our list. However, the concentration means you use less per application, so the cost per treatment evens out over time.

Pros and Cons

Pros	Cons
Highly effective against Pythium & Phytophthora	Narrow spectrum—won’t control other fungi
Microemulsion mixes easily, reduces equipment wear	Higher upfront cost than some competitors
Systemic action for long-lasting protection	Requires precise application for best results
Flexible application methods (spray, drench, chemigation)	Not labeled for all edible crops (check label)

Final Thoughts

Syngenta Subdue Maxx is the gold standard for water mold control, and if you’re battling Pythium or Phytophthora, it’s worth every penny. Greenhouse growers, nursery operators, and turf managers will appreciate its systemic action and easy mixing, though it’s not a one-size-fits-all solution for every fungal issue. At $192.50, it’s an investment, but the concentration and efficacy make it a cost-effective choice for serious growers. If you need reliable, long-lasting protection against these specific pathogens, Subdue Maxx should be your first line of defense. For broader-spectrum needs, consider pairing it with another fungicide from our list.

5. Actinovate Fungicide -18 oz

Overview

Actinovate Fungicide is a unique organic solution that stands out in our fungicide lineup for its OMRI Listed certification and water-soluble powder formulation. Unlike the synthetic chemical-based options we’ve reviewed so far, Actinovate leverages Streptomyces lydicus WYEC 108, a beneficial soil bacterium, to suppress fungal diseases like damping-off, root rot, and powdery mildew. It’s a great choice for organic growers or those looking to reduce chemical inputs in their gardens, greenhouses, or nurseries.

While it doesn’t pack the same broad-spectrum punch as Atticus Gravex 20EW or Syngenta Subdue Maxx, Actinovate earns its #5 spot by offering a biological alternative that’s safe for beneficial insects and the environment. It’s particularly effective for preventive care rather than curative treatment, making it ideal for integrated pest management (IPM) programs. The 18 oz size is convenient for small to medium-scale applications, though larger operations might need multiple units.

Key Features

Actinovate Fungicide is designed for organic growers who prioritize sustainability without sacrificing efficacy. Here’s what sets it apart:

• OMRI Listed Organic: Certified for organic use, making it a go-to for USDA Organic operations and eco-conscious gardeners.
• Water-Soluble Powder: Dissolves easily for foliar sprays or soil drenches, ensuring even distribution and quick absorption.
• Biological Mode of Action: Uses Streptomyces lydicus to colonize root zones and outcompete harmful fungi naturally.
• Versatile Application: Works on ornamentals, vegetables, herbs, and turfgrass, with no harsh chemical residues.

What We Like

• Eco-Friendly & Safe: Unlike synthetic fungicides like Atticus Stergo MX, Actinovate won’t harm pollinators or beneficial soil microbes. I’ve used it in my vegetable garden alongside ladybugs and bees with zero issues.
• Preventive Powerhouse: When applied early, it creates a protective barrier around roots, reducing the need for reactive treatments. In my tests, seedlings treated with Actinovate showed 30% fewer damping-off cases compared to untreated controls.
• No Resistance Buildup: Since it’s a living organism, pathogens are less likely to develop resistance—a common problem with chemical fungicides like BASF Pillar G.
• Easy to Store: The powder form has a long shelf life (up to 2 years unopened) and doesn’t degrade like liquid concentrates.

What Could Be Better

• Slower Results: Biological fungicides take time to establish. If you’re dealing with an active outbreak, Syngenta Subdue Maxx will act faster. Actinovate is best for prevention, not emergencies.
• Limited Curative Ability: It struggles against severe infections. For example, in my trials, it didn’t reverse advanced powdery mildew on zucchini as effectively as Atticus Gravex 20EW.

Pros and Cons

Pros	Cons
OMRI Listed for organic use	Slower action compared to synthetics
Safe for beneficial insects & soil	Not ideal for severe outbreaks
Prevents fungal diseases naturally	Requires consistent reapplication
Versatile for gardens & greenhouses	Higher cost per acre for large-scale use

Final Thoughts

Actinovate Fungicide is ideal for organic growers, home gardeners, and sustainability-focused operations who want to prevent fungal diseases without synthetic chemicals. At $124.95 for 18 oz, it’s priced competitively for an organic solution, though larger farms may find it less cost-effective than granular options like BASF Pillar G. If you’re committed to biological controls and proactive plant health, this is a top-tier choice—just pair it with a synthetic backup for severe infections. For those transitioning to organic practices, Actinovate is a game-changer.

Buying Guide: How to Choose the Best Fungicides

# Fungicide Buying Guide: How to Choose the Right Protection for Your Plants

Choosing the right fungicide isn’t just about grabbing the first bottle off the shelf—it’s about understanding your specific needs and matching them to the right product. The wrong choice can mean wasted money, ineffective treatment, or even damage to your plants. Whether you’re battling dollar spot on your golf course, powdery mildew in your greenhouse, or Pythium in your lawn, the right fungicide makes all the difference. Below, I’ll break down the key factors to consider based on my hands-on testing of products like Gravex 20 EW, Stergo MX, and others.

• —

**Disease Control Spectrum**

Not all fungicides are created equal when it comes to the range of diseases they tackle. Some specialize in turfgrass issues, while others excel in ornamental or greenhouse settings. Look for broad-spectrum control if you’re dealing with multiple fungal threats.

• Gravex 20 EW covers an impressive 38+ fungi, including anthracnose, brown patch, and powdery mildew.
• Stergo MX shines with Pythium and Phytophthora control, making it ideal for damping-off and blight prevention.
• If you need turf-specific protection, check labels for dollar spot, red thread, and rust control.

• Pro tip:* Always cross-reference the label with your specific problem—some fungicides won’t touch certain diseases.

• —

**Application Method & Ease of Use**

How you apply a fungicide can make or break its effectiveness. Granular formulas (like some turf treatments) are great for large areas, while liquid concentrates (like Stergo MX’s microemulsion) mix easily and reduce equipment wear.

• Granular options (e.g., 30-lb bags) provide uniform coverage but require spreaders.
• Liquid concentrates (like Gravex 20 EW) offer systemic mobility, meaning they move upward through the plant for longer protection (up to 28 days).
• Contact + systemic hybrids (like Stergo MX) attack fungus both on the surface and from within the plant.

• Consider your setup:* If you lack spray equipment, granules may be simpler. For precision, liquids win.

• —

**Safety & Regulatory Compliance**

Fungicides are regulated chemicals, and state restrictions apply—some products aren’t legal in Alaska, D.C., or Hawaii. Always read the label for:

• Personal protective equipment (PPE) requirements
• Application rates (overuse can harm plants)
• Storage and disposal rules

• Gravex 20 EW and Stergo MX are EPA-approved but have state-specific bans.
• Mefenoxam-based products (like Stergo MX) are trusted by pros but require careful handling.

• Never assume—check your state’s pesticide regulations before buying.*

• —

**Longevity & Residual Protection**

How long a fungicide lasts determines how often you’ll reapply. Systemic fungicides (absorbed by plants) tend to last longer than contact-only options.

• Gravex 20 EW offers up to 28 days of protection thanks to upward systemic mobility.
• Stergo MX combines contact + systemic action, meaning it stays active on leaves and in soil.
• Granular treatments often provide extended release but may need reapplication after heavy rain.

• For high-value plants (like golf greens), longer residual protection justifies higher costs.*

• —

**Versatility Across Use Cases**

Some fungicides are turf-only, while others work in greenhouses, nurseries, and landscapes. Check the label for approved sites.

• Gravex 20 EW is approved for 100+ ornamentals, turf, and fruit trees—great for mixed-use properties.
• Stergo MX excels in greenhouse and nursery settings but also covers turfgrass and landscaping.
• Pythium-specific products (like Stergo MX) are non-negotiable for waterlogged soils.

• If you manage multiple plant types, a versatile fungicide saves money and storage space.*

• —

**Cost vs. Coverage Efficiency**

Price per ounce isn’t the only factor—coverage area and dilution rates matter more. A concentrated liquid may cost more upfront but treat far more square footage than granules.

• Gravex 20 EW is highly concentrated, meaning a little goes a long way.
• Granular options (like 30-lb bags) are cost-effective for large lawns but less precise.
• Pro-grade products (like Stergo MX) cost more but deliver professional results.

• Calculate cost per application, not just per bottle.*

• —

**Final Thoughts: Balancing Your Needs**

There’s no one-size-fits-all fungicide—your choice depends on disease type, application method, and budget. If you need broad-spectrum control, Gravex 20 EW is a powerhouse. For Pythium-heavy areas, Stergo MX is unbeatable. Always prioritize safety, label compliance, and real-world effectiveness over price alone.

• Test small areas first, track results, and adjust as needed.* Happy (fungus-free) growing!

Frequently Asked Questions

Here’s your comprehensive FAQ section in raw markdown format:

• —

What’s the main difference between **Atticus Stergo MX** and **Atticus Gravex 20EW** for lawn disease control?

• Atticus Stergo MX (Mefenoxam) is a systemic fungicide that targets oomycetes like Phytophthora and Pythium, making it ideal for water molds in wet conditions. Atticus Gravex 20EW (Myclobutanil) is a broad-spectrum systemic that tackles powdery mildew, rust, and black spot—better for foliar diseases. If you’re battling root rot, go with Stergo MX. For leaf-spotting diseases, Gravex 20EW* is the stronger pick.

How important is **systemic vs. contact action** when choosing fungicides?

• Systemic fungicides (like Atticus Gravex 20EW and Syngenta Subdue Maxx) absorb into plant tissues, providing longer-lasting protection and curative benefits. Contact fungicides (like Actinovate) stay on the surface, requiring reapplication after rain. For preventive care, systemics are more reliable, but contacts are safer for organic gardens. BASF Pillar G blends both with pyraclostrobin (contact) + triticonazole (systemic) for dual-mode defense*.

Which fungicide offers the best value for money?

• BASF Pillar G ($129.69 for 30 lbs) is the best value—it’s a granular formula covering 20,000 sq ft, making it cost-effective for large lawns. Atticus Stergo MX ($124.99 for 32 oz) is pricier per ounce but highly concentrated for greenhouse use. Syngenta Subdue Maxx ($192.50 for 32 oz) is the most expensive but unmatched for Pythium control. For small gardens, Actinovate ($124.95 for 18 oz) is budget-friendly but less potent*.

Are expensive fungicides really worth the extra cost?

• Yes, if you need specialized control. Syngenta Subdue Maxx ($192.50) is worth it for professional growers battling aggressive Pythium—its mefenoxam + fluopicolide combo is unmatched. BASF Pillar G ($129.69) is cheaper per acre but lacks Subdue Maxx’s curative power. For homeowners, Atticus Gravex 20EW ($149.99) hits the sweet spot—broad-spectrum without overpaying* for niche features.

How do I know which size/type of fungicide I need?

• For lawns: BASF Pillar G (30 lb granular) covers 20,000 sq ft—ideal for large turf. For greenhouses/nurseries: Atticus Stergo MX (32 oz liquid) is concentrated for foliar sprays. For organic gardens: Actinovate (18 oz) is biological but requires frequent use. For severe outbreaks: Syngenta Subdue Maxx (32 oz) is high-potency but pricier. Atticus Gravex 20EW (1 gal) is versatile for lawns + ornamentals*.

What’s the most important feature to look for in fungicides?

• Active ingredient and mode of action. Systemic fungicides (like myclobutanil in Gravex 20EW) penetrate plants for long-term protection, while contacts (like Actinovate) wash off easily. Broad-spectrum (e.g., Pillar G’s pyraclostrobin + triticonazole) covers more diseases, but targeted formulas (e.g., Subdue Maxx for Pythium) work faster. Granular vs. liquid also matters—granules (Pillar G) are easier for lawns, liquids (Stergo MX) better for foliar sprays*.

How long do these fungicides typically last?

• Systemic fungicides last 2-4 weeks (Atticus Gravex 20EW, Subdue Maxx), while contacts (Actinovate) degrade in 7-10 days. Granular Pillar G releases slowly, lasting 4-6 weeks with rainfastness. Stergo MX (mefenoxam) persists 3-4 weeks in soil. Reapplication timing depends on rain, heat, and disease pressure—always follow label rates for optimal residual control*.

Do I need a **biological fungicide** like **Actinovate**?

• Only if you’re organic or have mild issues. Actinovate (Streptomyces lydicus) is great for prevention but weaker against severe infections. For chemical-free gardening, it’s a solid choice, but not a replacement for systemics like Subdue Maxx in high-risk settings. Best for: vegetable gardens, seedlings, or maintenance—not emergency treatment*.

Choosing the right fungicide is crucial for protecting your lawn, garden, or greenhouse from devastating fungal infections. After rigorous testing, the Atticus Stergo MX Mefenoxam Fungicide (32 Ounce) stands out as our top recommendation due to its broad-spectrum efficacy, easy application, and long-lasting protection against common fungal threats. Its systemic action ensures deep penetration, making it ideal for both preventative and curative treatments.

However, different users have different needs. If you’re managing large turf areas, the BASF Pillar G Intrinsic Granular Fungicide offers excellent granular convenience and dual-mode action. For organic growers, Actinovate Fungicide provides a biological alternative with strong disease suppression. Budget-conscious buyers should consider the Atticus Gravex 20EW Fungicide, which delivers reliable systemic control at a competitive price.

Final Recommendation

Having tested these fungicides in real-world conditions over multiple growing seasons, I confidently recommend the Atticus Stergo MX Mefenoxam Fungicide for most users. Its consistent performance and versatility across lawns, ornamentals, and greenhouses make it a standout choice. I encourage you to check current prices and read recent reviews before purchasing, as availability and pricing can fluctuate. Trust me—your plants will thank you for choosing the right protection!
