Chemical properties and systemic mode of action
Dimethoate is readily absorbed by foliage and roots, moving acropetally through plant xylem to provide comprehensive internal defense.
- Inhibits the acetylcholinesterase (AChE) enzyme, causing continuous accumulation of acetylcholine in insect nerve synapses.
- Systemic and contact action: Destroys hidden sucking pests feeding on leaf undersides while eliminating exposed pests on contact.
- Moderate acaricidal activity: Helps suppress minor red spider mite flare-ups in field and horticultural crops.
- Formulated as an emulsifiable concentrate (30% EC) that dilutes readily in water for foliar spraying.
Registered crops and target pest control
Rogor is approved under CIBRC regulations across diverse agricultural commodities for targeted pest management.
- Cotton: Effective management of aphids, jassids, and thrips during early vegetative stages.
- Mustard and rapeseed: Rapid control of mustard aphids (Lipaphis erysimi) during flowering and pod development.
- Pulses and oilseeds: Control of leafhoppers, whiteflies, and pod-sucking bugs.
- Vegetables and orchards: Control of leaf miners, mealybugs, and sucking insect vectors.
Application precautions and safety guidelines
Because Dimethoate is an organophosphate compound with cholinesterase-inhibiting properties, applicators must observe strict personal protective protocols. Wear chemical-resistant gloves, goggles, and face shields. Observe the mandatory pre-harvest interval (PHI) specified on the container label, and avoid spraying during peak daylight flowering to protect beneficial pollinators.

Common questions
What is the active ingredient in Rogor insecticide?
Rogor contains Dimethoate 30% EC, a systemic organophosphate insecticide and acaricide.
Which insect pests does Dimethoate primarily control?
It primarily controls sap-sucking insects including aphids, jassids, thrips, whiteflies, and leaf miners.
Why is observing the pre-harvest interval (PHI) essential for Rogor?
Observing the label PHI ensures that chemical residues degrade below statutory maximum residue limits (MRLs) before crops are harvested for consumption.
