Active Ingredient Profile and Strobilurin Action
Tata Ergon contains Kresoxim-methyl (44.3% SC), an agricultural strobilurin fungicide.
It binds to the Qo site of cytochrome b in mitochondrial Complex III, shutting down ATP energy generation in fungal cells.
Its unique vapor activity and translaminar mobility enable it to redistribute across un-sprayed leaf surfaces and protect dense canopy interiors.
- Formulation: 44.3 percent Suspension Concentrate (SC)
- Gas phase action: Mild vapor pressure redistributes active molecules into dense cluster interiors
- Translaminar movement: Penetrates waxy cuticles to protect both upper and lower leaf surfaces
Target Crop Diseases and Approved Registrations
Tata Ergon is approved across high-value temperate and subtropical horticultural crops.
It is particularly valued in viticulture and apple orchards for controlling apple scab and powdery mildew without marking fruit surfaces.
- Apple: Primary weapon against apple scab (Venturia inaequalis) and powdery mildew
- Grapes: Controls powdery mildew (Uncinula necator) on leaves and berry bunches
- Vegetables and cereals: Suppresses powdery mildew and foliar blight complexes
Application Guidelines, Mixing, and Resistance Management
Apply preventively at early vegetative flush or during early cluster development before disease becomes severe.
Dilute the suspension concentrate in clean water with continuous agitation and apply using fine mist sprayers.
Rotate with multi-site contact protectants to maintain long-term chemical efficacy.
- Preventive application: Best results achieved when applied ahead of rainfall or fungal spore release
- Resistance stewardship: Limit total seasonal strobilurin applications and rotate with contact fungicides
- Safety apparel: Wear protective clothing, rubber gloves, and an approved dust respirator during mixing
