Powdery Mildew Chemical Control — Chlorothalonil 10% + Hexaconazole 5% + Ethirimol 5% FU

Powdery Mildew — What It Is and Why It Hurts

What it is
Powdery mildew is a true fungus disease (e.g., Erysiphe, Leveillula, Oidium). It grows on the leaf surface and sends feeding structures into cells.

How to recognize it

• White, powdery patches on leaves, stems, sometimes fruit.
• Leaves yellow, curl, and age early; severe cases cause leaf drop.
• Spots often start on upper leaves or shaded, crowded areas.

When it thrives

• Warm days + cool nights, high humidity, and little free water (it doesn’t need leaf wetness like many other fungi).
• Dense canopies, poor airflow, and late-day irrigation increase risk.

Why growers care

• Less photosynthesis → less yield and weaker plants.
• Poor fruit quality (sunburn after defoliation, size and grade loss).
• Fast spread in greenhouses and tunnels, especially during long production cycles.

What control needs to do

• Protect clean leaves from new spores.
• Stop early internal growth inside tissue.
• Reach leaf undersides and inner canopy where symptoms and spores hide.
• Combine fungicides with airflow, humidity control, and sanitation.

Mode of Action — How the Triple Formula Works

Three actives, three functions, one complete program.
This formulation merges multi-site protection, systemic curative action, and targeted anti-mildew performance—designed to stop powdery mildew at every stage.

1. Chlorothalonil (10%) — Multi-site protectant (FRAC M05)

• Forms a durable surface shield on the leaf.
• Prevents spore germination and infection.
• Acts on multiple biochemical sites, making resistance rare.
• Supports the two systemic partners by reducing spore load and protecting new tissue.

2. Hexaconazole (5%) — DMI systemic fungicide (FRAC 3)

• Moves through the leaf (systemic and translaminar).
• Inhibits ergosterol synthesis, an essential fungal cell membrane component.
• Provides curative and residual protection for internal infections.
• Excellent for halting disease expansion in infected tissue.

3. Ethirimol (5%) — Powdery-mildew-specific systemic (FRAC 13)

• Penetrates leaf tissues rapidly; active against Erysiphe and Leveillula.
• Inhibits nucleic acid synthesis, stopping fungal growth inside host cells.
• Adds strong selectivity for powdery mildew fungi while minimizing off-target stress.

How they complement each other

• Surface + inside + selectivity: chlorothalonil blocks new infection; hexaconazole clears internal colonies; ethirimol sterilizes surviving mycelium.
• Broader protection: fits well into FRAC rotation programs—mix of multi-site + two distinct single-site chemistries.
• Longer protection window: contact + systemic actives ensure both short-term knockdown and lasting control.

FU Formulation Advantages — Why Smoke Beats Spray in Greenhouses

What FU means
FU = smoke generator. It releases fine particles that travel with air currents, then settle on all leaf surfaces—including the undersides and deep inner canopy.

Key advantages

• Full coverage: Reaches spray blind spots and dense foliage layers.
• No water needed: Useful in humid periods or when spraying is impractical.
• Low labor, quick cycles: Night-time activation, minimal equipment and downtime.
• Uniform deposition: Air dispersion creates even loading across the house.
• Less drift, better hygiene: Closed space + dry application reduce splash and runoff.
• Program-friendly: Fits between spray rounds without blocking lines or teams.

Principles of use (label-first)

• Enclosed/semi-enclosed facilities only.
• Ventilate after treatment and respect REI before re-entry.
• Handle ignition and placement exactly as directed on the label; use PPE.

Applications & Target Crops

Where it fits best

• Greenhouses / plastic tunnels with recurring powdery mildew.
• Dense canopies where sprays miss leaf undersides and inner layers.
• Night-time program slots between spray rounds or when spraying is impractical.

Target crops (protected cultivation)

• Cucurbits: cucumber, melon, zucchini, pumpkin.
• Solanaceous crops: tomato, pepper, eggplant.
• Legumes: beans, peas.
• Leafy greens & herbs: lettuce, spinach, basil, parsley, dill.
• Ornamentals & nursery stock grown under cover.

Pathogens addressed (examples)

• Erysiphe spp., Podosphaera spp., Oidium spp., Leveillula spp. (powdery mildew fungi).

When to trigger (principle only)

• Before forecasted outbreaks (warm days + cool, humid nights).
• At first visible patches on upper leaves or shaded areas.
• When spray access is limited; use as a night-time step and maintain FRAC rotation.

Resistance Management & IPM Integration

Objective: keep powdery mildew pressure low and protect the efficacy of all FRAC groups over time.

Chemistry principles (label-first)

• Rotate FRAC groups: This product combines M05 + 3 + 13. Alternate with other approved groups in your market (e.g., 7 (SDHI), 11 (QoI – use cautiously due to resistance), 5 (morpholines), U6/U8 where registered).
• Avoid repeats: Do not run the same single-site FRAC group back-to-back across cycles.
• Use at the right moment: Preventive at risk forecasts or early-curative at first patches; keep it as part of a programmed sequence, not a one-off fix.

Greenhouse IPM — reduce conditions that favor powdery mildew

• Humidity & airflow: Ventilate to avoid prolonged humid air around leaves; target dry foliage overnight.
• Irrigation timing: Water early day; avoid late-day irrigation that keeps foliage humid.
• Canopy management: Prune, trellis, and space plants to open the canopy; improve air movement to shaded interiors.
• Nutrition balance: Avoid excessive nitrogen that drives lush, susceptible growth.
• Sanitation: Remove heavily infected leaves; clean tools, benches, and trays; manage volunteer hosts.
• Cultivar & transplants: Choose tolerant varieties where available; start with clean, inspected seedlings.
• Monitoring: Scout upper surfaces and shaded nodes; log pressure, weather, and interventions.

Compliance & Safety (Principles Only)

Intended use

• For enclosed or semi-enclosed facilities such as greenhouses, tunnels, and propagation rooms.
• Not registered for open-field use.

Label compliance

• Always follow the local registration and product label for approved crops, pathogens, and restrictions.
• Note: Chlorothalonil is restricted or phased-out in some regions—confirm status before import or use.

Worker safety

• Wear PPE per label (eye, skin, and respiratory protection).
• During activation, ensure only trained operators remain in the house.
• After smoke disperses, ventilate fully and observe the re-entry interval (REI) before workers re-enter.
• Keep people, animals, and beneficial insects outside the treated area until REI ends.

Storage & transport

• Store sealed units in a cool, dry, ventilated place, away from fire, heat, and moisture.
• Keep separate from food, feed, and seed; avoid direct sunlight.
• Handle and dispose of residues and packaging under hazardous-waste regulations.

Environmental protection

• Prevent smoke or residue from venting outdoors or entering water systems.
• Dispose of empties responsibly—never burn or bury uncontrolled.

Risk concept

• Risk = Hazard × Exposure.
  Chlorothalonil, hexaconazole, and ethirimol each act on fungal biology; the user’s job is to minimize exposure through correct site selection, ventilation, and PPE.

Safety first: When local rules differ, always apply the most conservative requirement on your label or national regulation.
