Introduction
In the constant battle against agricultural pests, farmers need powerful solutions that combine immediate knockdown with long-term protection. Buprofezin 15% + Acephate 35% WP (Odis) represents a strategic insecticide combination that delivers exactly this – offering both contact and systemic action against a wide range of sucking and chewing pests. This 800-word, plagiarism-free guide provides farmers with complete technical details, application protocols, and resistance management strategies for this innovative insecticide.
Understanding the Odis Advantage
Composition & Formulation
- Buprofezin 15% (Insect growth regulator)
- Acephate 35% (Organophosphate insecticide)
- Formulation: Wettable Powder (WP)
Key Features
✔ Dual mode of action for complete pest control
✔ Broad-spectrum efficacy against resistant pests
✔ Systemic + contact activity
✔ Economic with long residual effect (15-20 days)
Dual Mode of Action Explained
1. Acephate Component
- Type: Systemic organophosphate
- Action:
- Inhibits acetylcholinesterase enzyme
- Causes nervous system failure in insects
- Provides knockdown within 30 minutes
2. Buprofezin Component
- Type: Insect growth regulator (IGR)
- Action:
- Inhibits chitin synthesis
- Disrupts molting process
- Provides long-term control of nymphs
Synergistic Effect: Immediate kill of adults + prevention of next generation

- Application Timing: Pest appearance at tillering stage
Cotton Protection
Pest | Dosage | Application Method |
Whitefly | 600g/acre | Foliar spray |
Aphids | 500g/acre | Foliar spray |
Vegetable Crops
- Chilli: 0.3% solution for thrips control

- Recommended for dense canopy crops
- Water volume: 300-400L/acre
- Tank Mix Compatibility
- Compatible with most fungicides
- Avoid alkaline mixtures (pH>8.5)
Resistance Management Strategy
To prevent pest resistance:
- Rotate with neonicotinoids (e.g., Imidacloprid)
- Limit to 2 applications per season
- Combine with biological controls
- Monitor pest populations weekly
Recommended Rotation Schedule:
- First spray: Odis
- Second spray: Thiamethoxam
- Third spray: Spinosad
