Active Ingredient Profile and Protective Mechanism
Clutch contains a modern strobilurin/QoI active chemical formulated as dry water-dispersible granules.
It works by binding to the Qo site of mitochondrial Complex III in fungal cells, halting electron transport and shutting down ATP production.
This rapid cellular energy deprivation blocks fungal spore germination, germ tube elongation, and initial host plant penetration.
- Mode of action: Quinone outside inhibitor (QoI) stopping fungal cellular respiration
- Translaminar redistribution: Penetrates leaf cuticles to protect both upper and lower leaf surfaces
- Spore germination block: Highly effective when applied preventively ahead of pathogen arrival
Target Crop Diseases and Broad Spectrum Efficacy
Clutch is registered for managing destructive fungal diseases in vegetables, fruit orchards, and commercial cash crops.
Preventive application maintains leaf canopy vigor, supports chlorophyll integrity, and prevents cosmetic fruit damage.
- Vegetables: Controls early blight, powdery mildew, and anthracnose fruit rot complexes
- Grapes and fruit crops: Suppresses downy mildew, powdery mildew, and foliar leaf spots
- Field crops: Protects pulse and oilseed crops from fungal foliar epidemics
Spraying Instructions, Water Volume, and Stewardship
Mix the recommended granules in clean, sediment-free water with continuous agitation.
Apply using well-maintained knapsack sprayers fitted with fine cone nozzles for uniform foliar misting.
To prevent resistance development, alternate applications with multi-site contact fungicides like Mancozeb.
- Application timing: Apply preventively at the onset of favorable disease weather conditions
- Resistance rotation: Rotate with contact protectants from different FRAC chemical groups
- Safety apparel: Wear protective rubber gloves, mask, and safety goggles during mixing

Common questions
What type of fungicide is Clutch?
Clutch is a broad-spectrum strobilurin fungicide with preventive, translaminar, and curative disease control properties.
How does Clutch fungicide prevent fungal infection?
It inhibits mitochondrial respiration in fungal spores, preventing energy generation and halting spore germination.
Can Clutch be rotated with contact fungicides?
Yes, rotating Clutch with multi-site contact fungicides like Mancozeb or Copper Oxychloride prevents resistant fungal strains.
