Rogohit Insecticide (Dimethoate 30% EC) - HPM
The Dual-Action Specialist for Sucking Pests and Stem Borers.
Rogohit is a trusted insecticide from HPM Chemicals that provides complete protection for your crops. It contains Dimethoate 30% EC, a powerful formula that works in two ways: it kills pests on contact and enters the plant system to provide long-lasting internal protection.
It is highly effective against "hidden" pests like Stem Borers in Maize and sucking pests like Aphids and Jassids in Cotton. Because it is systemic, it protects new leaves that grow after spraying.

How It Works: Mode of Action
Rogohit targets the nervous system of the insect (AChE Inhibitor), causing paralysis and death.
- Contact Action: The moment the spray hits the insect, it penetrates their outer layer and kills them.
- Systemic Action: The chemical enters the plant's sap stream and moves upwards (Acropetal movement).
- Stomach Poisoning: When pests like Aphids or Stem Borers try to eat the plant or suck sap, they ingest the poison and die.
Note: This systemic nature makes it rainfast once absorbed by the plant.
