Dual Active Chemistry and Synergistic Modes of Action
Avtar synergizes Hexaconazole (a systemic triazole) with Zineb (a contact dithiocarbamate) in a wettable powder formulation.
Hexaconazole translocates systemically through plant xylem, inhibiting fungal ergosterol biosynthesis and arresting established hyphae.
Zineb forms an exterior contact protective barrier that inhibits spore germination while supplying bioavailable zinc nutrients to foliage.
- Hexaconazole (4%): Systemic triazole providing curative and eradicant fungal control
- Zineb (68%): Multi-site surface contact protectant complexed with bioavailable elemental zinc
- Resistance prevention: Multi-site partner shields the single-site triazole from fungal resistance
Target Crop Diseases and Broad Spectrum Efficacy
Avtar is registered across paddy, apples, groundnut, tea, and vegetable crops.
It is recognized for simultaneously controlling fungal foliar diseases and delivering a noticeable nutritional greening effect.
Applications must be timed preventively ahead of rainy weather or immediately upon noticing early foliar lesions.
- Paddy: Controls sheath blight (Rhizoctonia solani) and blast (Pyricularia oryzae)
- Apple: Manages apple scab (Venturia inaequalis) and premature leaf fall
- Groundnut and pulses: Suppresses Tikka leaf spot and rust complexes
Slurry Preparation, Mixing, and Safety
Always make a smooth pre-slurry in a separate container of water before adding to the main spray tank to ensure complete powder suspension.
Maintain continuous tank agitation during spraying and observe recommended pre-harvest intervals before food crop harvest.
Wear standard personal protective equipment during handling.
- Pre-slurry mixing: Dissolve powder in a bucket of clean water before diluting into the sprayer tank
- Canopy wetting: Spray both upper and lower canopy surfaces until leaves are evenly coated
- Personal protection: Wear protective rubber gloves, dust mask, and safety goggles during handling
