Chemical Class and Mode of Action
Rogor combines systemic translocation with rapid contact and stomach action.
Key biochemical attributes:
- Active ingredient: Dimethoate at 30% concentration in an emulsifiable concentrate (EC) formulation.
- Chemical class: Organophosphate insecticide and acaricide.
- Enzyme inhibition: Binds to acetylcholinesterase (AChE), causing accumulation of acetylcholine and subsequent neurotoxic failure in target insect pests.
- Plant absorption: Absorbed through foliage and transported systemically throughout the vascular system, protecting emerging leaves.
Registered Target Crops and Pest Spectrum
Dimethoate is widely registered for managing severe sucking and mining insect complexes.
Major crop applications:
- Cotton: Controls early-season sucking pests including aphids, jassids, thrips, and whiteflies.
- Chilli and vegetables: Manages leaf miners, aphids, and thrips that curl leaves and transmit plant viruses.
- Cereals and pulses: Effectively suppresses shoot fly in sorghum and pod borers or aphids in grain legumes.
- Mite control: Delivers supplementary acaricidal activity against phytophagous spider mites in commercial plantings.
Safe Handling, Dosage and Harvest Intervals
Adhering to strict safety guidelines safeguards applicators, beneficial pollinators, and food consumers.
Operational precautions:
- Follow approved dosage: Mix strictly at label-recommended dilutions per liter of clean water to avoid chemical leaf scorch.
- Pollinator safety: Avoid spraying during peak honeybee foraging hours in the morning to prevent pollinator toxicity.
- Pre-harvest interval (PHI): Respect mandatory waiting periods between chemical spraying and produce harvesting as specified on product labels.
- Protective equipment: Always wear protective rubber boots, nitrile gloves, and a carbon-filter respirator when handling concentrates.

Common questions
What is the active ingredient in Rogor pesticide?
Rogor contains Dimethoate 30% EC, a broad-spectrum systemic organophosphate insecticide and acaricide.
How does dimethoate eliminate sucking insect pests?
It inhibits the acetylcholinesterase enzyme, causing nervous system disruption in pests feeding on plant sap.
Is Rogor safe for beneficial insects like bees?
Dimethoate is toxic to bees; spraying should be avoided during active flower bloom and peak morning pollinator activity.
