Mode of Action and Pest Spectrum
Belonging to the carbamate group (IRAC Group 1A), Carbosulfan acts as a reversible inhibitor of the acetylcholinesterase (AChE) enzyme in the insect nervous system. The accumulation of acetylcholine leads to continuous neurotransmission, twitching, paralysis, and insect mortality.
Its xylem mobility allows it to protect newly emerging vegetative shoots after foliar or basal soil application.
- Paddy: Green leafhopper (Nephotettix virescens), brown planthopper, and yellow stem borer.
- Cotton: Whitefly, jassids, aphids, and thrips complex.
- Vegetables and pulses: Pod borers, aphids, and foliar chewing larvae.
- Systemic translocation: Moves through xylem vascular tissues to protect newly emerging shoots and leaves.
Handling Precautions and Pre-Harvest Guidelines
As a Class II moderately hazardous pesticide, Carbosulfan requires strict adherence to safety protocols during mixing, spraying, and storage.
Proper disposal of empty packaging prevents localized contamination of soil and groundwater sources.
- Always wear protective gloves, boots, mask, and goggles when handling the liquid concentrate.
- Respect the label pre-harvest interval (PHI) to ensure harvested produce carries no violative chemical residues.
- Never empty washings or contaminated containers into irrigation canals, ponds, or open streams.
