Organophosphate Insecticide
PIRIMIPHOS-METHYL 50% EC
A broad-spectrum organophosphate insecticide with contact, stomach, and fumigant action. Provides rapid knockdown and extended residual control of stored grain pests and field insects with minimal mammalian toxicity.
Active: Pirimiphos-methyl
Formulation: EC (Emulsifiable Concentrate)
Action: Cholinesterase Inhibitor
Product Information
Mode of Action
Pirimiphos-methyl inhibits the acetylcholinesterase enzyme at nerve synapses, causing an accumulation of acetylcholine. This results in continuous nerve stimulation, leading to tremors, paralysis, and death. It demonstrates excellent vapor action, making it effective in enclosed spaces (stored grains).
Target Pests
- Grain weevils (Sitophilus spp.)
- Aphids (Aphis spp., Myzus persicae)
- Whiteflies (Bemisia tabaci)
- Thrips (Frankliniella spp.)
- Bollworms (Helicoverpa spp.)
Applicable Crops
Stored grains, Wheat, Maize, Rice, Vegetables, Cotton, and Ornamentals.
Recommended Dosage
| Crops | Target Pest | Dosage / ha | Formulation (ml) |
|---|---|---|---|
| Stored Grains | Grain weevils, Beetles | – | 4-8 ml / ton grain |
| Vegetables | Aphids, Whiteflies | 500-750 | 500-750 |
| Cotton | Bollworms, Aphids | 750-1000 | 750-1000 |
| Ornamentals | Aphids, Thrips | 400-600 | 400-600 |
For stored grains, dosage is calculated per ton of grain, not per hectare. Ensure even distribution.
Application Instructions
1. Field Application
For Vegetables, Cotton, and Ornamentals, mix the specified dosage in sufficient water to ensure full coverage of foliage. Apply at the first sign of infestation.
2. Stored Grain Application
This product has strong fumigant action. When applying to stored grains (Wheat, Maize, Rice), ensure the storage area is enclosed to maximize the effect of the vapor action against weevils and beetles.
Safety Precautions
Organophosphate Warning: This product acts as a cholinesterase inhibitor.
Handling: Wear full protective gear (gloves, mask, goggles) to avoid contact with skin and inhalation of vapors, especially when using in enclosed grain storage areas.
