Chemical Class and Ryanodine Receptor Mode of Action
Chlorantraniliprole belongs to the anthranilic diamide chemical class (IRAC Group 28). It functions by binding selectively to ryanodine receptors located in insect muscle cells, stimulating the unregulated release of intracellular calcium ion stores.
This depletion halts muscle contraction, inducing rapid feeding cessation, muscular paralysis, and death. Susceptible larvae stop feeding within hours of ingestion, preventing further boring and foliage injury.
- IRAC Group 28 Mode of Action: Targets ryanodine receptors with zero cross-resistance to legacy organophosphates or pyrethroids.
- Systemic & Translaminar Movement: Absorbed rapidly by foliage and root systems, redistributing acropetally to protect newly expanding leaves.
- Suspension Concentrate (SC): Water-based formulation ensuring easy spray mixing and superior adherence to leaf cuticles.
Target Pests and Labeled Crops
Slayer Pro is registered under CIBRC standards for controlling economically damaging lepidopteran pests across field and vegetable crops. In paddy farming, it delivers protection against yellow stem borer (Scirpophaga incertulas) and leaf folder (Cnaphalocrocis medinalis).
In sugarcane, it prevents early shoot borer and top borer; in cotton, it manages American bollworm and spotted bollworm; and in vegetables, it protects tomato and brinjal against fruit borers.
- Paddy Crop Defense: Prevents dead hearts during vegetative tillering and white heads during panicle emergence.
- Sugarcane Health: Protects emerging cane tillers against boring caterpillars.
- Vegetable Fruit Protection: Prevents internal larval boring in developing tomato and brinjal fruits.
Application Guidelines and Resistance Stewardship
Apply Slayer Pro at early egg hatch or when first-instar caterpillar larvae begin feeding. Ensure thorough foliar coverage using calibrated hollow cone nozzles on knapsack sprayers.
To prevent diamide resistance among caterpillar populations, rotate Slayer Pro with insecticides having different modes of action (such as spinosyns, avermectins, or oxadiazines) within the crop cycle.
- Rainfast Property: Demonstrates excellent rainfastness once spray droplets have completely dried on foliage.
- Safety Profile: High safety margin for beneficial predatory insects like spiders and honeybees when applied per label directions.
- Pre-Harvest Interval (PHI): Observe statutory waiting periods specified on the registered product packaging.
