Dual mode of action and chemical composition
Barazide combines two complementary active ingredients from distinct chemical classes to deliver broad-spectrum caterpillar management and delay insecticide resistance.
Novaluron belongs to the benzoylurea group and acts as an Insect Growth Regulator (IGR) that inhibits chitin synthesis during larval moulting, preventing larvae from maturing into the next instar.
- Novaluron (5.25% SC): Chitin synthesis inhibitor halting larval moulting and development.
- Emamectin Benzoate (0.9% SC): Avermectin neurotoxin stimulating GABA receptors, causing rapid paralysis and cessation of feeding.
- Synergistic knockdown: Provides immediate feeding cessation followed by complete mortality during larval development.
Target crops and pest spectrum
The dual formulation is registered for controlling destructive chewing and boring caterpillar pests across diverse agricultural and horticultural crops.
It proves particularly effective against diamondback moth (DBM) in cole crops, fruit and shoot borer in solanaceous vegetables, pod borer complexes in pulses, and fall armyworm in maize.
- Cabbage and Cauliflower: Diamondback moth (Plutella xylostella) and tobacco caterpillar.
- Chilli and Tomato: Fruit borers (Helicoverpa armigera) and Spodoptera litura.
- Pigeon Pea and Chickpea: Helicoverpa pod borer and spotted pod borer.
- Maize: Fall armyworm (Spodoptera frugiperda) during vegetative whorl stages.
Application timing and safety guidelines
For optimum field performance, apply Barazide upon first noticing egg hatching or young first-to-second instar caterpillars before they bore into fruits or pods.
Maintain uniform foliar coverage using a knapsack or motorized sprayer equipped with a hollow cone nozzle, strictly adhering to container label dilution guidelines.
- Timing: Spray at early larval infestation stages when larvae are actively feeding on foliage.
- Coverage: Ensure thorough wetting of upper and lower leaf surfaces and developing fruiting bodies.
- Protective measures: Wear protective clothing, rubber gloves, and face shield; avoid spraying during extreme midday temperatures.

Common questions
What is the chemical composition of Barazide insecticide?
Barazide is formulated as Novaluron 5.25% + Emamectin Benzoate 0.9% SC (suspension concentrate).
How does Barazide work against caterpillars?
It combines an insect growth regulator (Novaluron) that stops chitin formation with a nerve toxin (Emamectin Benzoate) that paralyzes the insect.
Which crops can Barazide be applied on?
It is commonly used on cabbage, cauliflower, chilli, tomato, pulses, and maize to control chewing and boring caterpillars.
