Chemical classification and mode of insecticidal action
Marshal contains Carbosulfan 25% EC (emulsifiable concentrate), an active compound belonging to the carbamate chemical family.
It acts as a reversible inhibitor of the acetylcholinesterase (AChE) enzyme in the insect nervous system. Upon entering the insect body, Carbosulfan hydrolyzes into carbofuran metabolites that bind AChE, triggering intense neuromuscular excitation, paralysis, and pest death.
- Active ingredient: Carbosulfan 25% EC.
- Chemical class: Carbamate (Acetylcholinesterase enzyme inhibitor).
- Triple action: Delivers systemic absorption, contact knockdown, and stomach poison action with excellent residual persistence.
Approved crops and target pest spectrum
Marshal is registered in India for managing destructive chewing and sucking insect complexes across field and cash crops.
It is especially valued in rice cultivation for controlling early vegetative pests, including stem borers and gall midges.
- Paddy (Rice): Green leafhopper, brown planthopper, stem borer, gall midge, and whorl maggot.
- Cotton: Whiteflies, aphids, jassids, and thrips.
- Chillies: Thrips, aphids, and fruit borers.
- Vegetable crops: Diamondback moth in crucifers and fruit borers in solanaceous vegetables.
Application methods and chemical safety guidelines
Marshal can be applied as a foliar spray or as a seedling root dip treatment prior to transplanting paddy seedlings.
Because carbamates are potent neurotoxicants, operators must observe strict chemical handling and protective clothing protocols.
- Foliar spray: Mix at label-prescribed concentrations in clean water; spray uniformly across the crop canopy.
- Seedling root dip: Dip rice seedling roots in a shallow wash before transplanting to shield seedlings against early vegetative pests.
- Protective equipment: Wear chemical-resistant overalls, gloves, respirator mask, and protective eyewear; observe designated pre-harvest intervals.
