Active Ingredient Chemistry and Systemic Protection
Dimethoate (IRAC Group 1B) acts as a potent inhibitor of the acetylcholinesterase (AChE) enzyme in insect nervous systems. The continuous accumulation of acetylcholine causes uncoordinated muscle tremors, paralysis, and insect mortality.
Its high xylem systemic mobility allows it to translocate rapidly through plant tissues, protecting newly emerging terminal shoots against sucking pests.
- Target sucking pests: Aphids, jassids, thrips, whiteflies, and painted bug.
- Acaricidal action: Effective against phytophagous spider mite complexes across field crops and orchards.
- Systemic penetration: Moves through plant vascular channels, controlling hidden insects feeding on plant sap.
- Major approved crops: Cotton, mustard, pulses, chillies, mango, and onion per CIBRC approved label clearances.
Spray Timing, Pollinator Care, and Safety Standards
Because Dimethoate possesses an organophosphate chemical structure, applicators must follow strict safety precautions during handling and spraying.
Never apply during crop bloom to avoid harming foraging honeybees and beneficial pollinators.
- Wear personal protective gear including chemical gloves, goggles, apron, and an organic vapor respirator during dilution.
- Avoid spraying during active flowering periods when honeybees are foraging in the field.
- Respect the registered pre-harvest interval (PHI) to prevent illegal pesticide residues on harvestable produce.

Common questions
What is the active ingredient in Rogor insecticide?
Rogor contains Dimethoate 30% EC, a systemic organophosphate insecticide and acaricide.
Which pests does Rogor primarily control?
It primarily controls sap-sucking insects such as aphids, jassids, thrips, whiteflies, and spider mites.
Can Rogor be sprayed when crops are in bloom?
No, Dimethoate is toxic to honeybees; avoid spraying during active flowering to safeguard pollinators.
