How Acemain Works: Mode of Action
Acemain neutralizes severe insect infestations through an advanced and uncompromising biological process:
- Complete Systemic Absorption: The water-soluble powder dissolves effortlessly, entering the plant's vascular system. It travels deep into hidden micro-environments where pests hide, protecting even newly grown leaves.
- Nervous System Disruption: Upon contact or ingestion, it irreversibly blocks vital enzymes in the insect's nervous system, causing violent tremors, paralysis, and rapid death.
- Toxic Amplification: Once ingested, the insect's own gut naturally converts the active ingredient into an even deadlier compound, ensuring absolute pest elimination.
By attacking pests from the outside in and the inside out, Acemain ensures no crop-destroying insect survives.

How to Apply Acemain: Field Best Practices
- Timing: Spray during the cooler early morning or late evening hours. Apply at the very first visual sign of pest damage to prevent large-scale outbreaks.
- Mixing: Thoroughly dissolve 1 to 2 grams of powder per liter of water. It mixes easily without foaming, making it highly efficient for field preparation.
- Coverage: Ensure deep, uniform spray distribution across the entire crop canopy. It performs perfectly in manual knapsack sprayers, tractor booms, and modern agricultural spraying drones.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during peak bee foraging hours to protect pollinators.
Frequently Asked Questions
1. What is Acemain (Acephate 75% SP) primarily used for?
It is a powerful systemic and contact insecticide designed to eradicate stubborn sucking and chewing pests in crops like cotton, rice, chillies, and vegetables.
2. Will rain wash away the Acemain spray?
No. Acemain boasts excellent rainfastness. Once it is absorbed into the leaf surface—usually within 3 hours of spraying—it continues to protect the crop reliably.
