Chemical properties and neurotoxic mode of action
Marshal contains Carbosulfan 25% EC, an active ingredient belonging to the carbamate chemical family.
It functions by reversibly inhibiting acetylcholinesterase (AChE) in the insect nervous system. Upon entering the insect body, Carbosulfan metabolizes into carbofuran, causing rapid acetylcholine buildup at nerve synapses, resulting in violent tremors, paralysis, and pest mortality.
- Active chemical: Carbosulfan 25% EC.
- Chemical class: Carbamate (Acetylcholinesterase inhibitor).
- Triple action: Delivers systemic plant absorption, contact knockdown, and ingestion stomach action.

Marshal can be applied as a foliar spray or as a seedling root dip treatment prior to transplanting paddy seedlings into puddled fields.
Due to its carbamate chemistry, applicators must follow strict chemical handling protocols and wear complete personal protective equipment.
- Foliar spray: Mix at label-recommended dilutions in clean water; spray uniformly across the crop canopy.
- Seedling root dip: Dip rice seedling roots in a shallow wash for 8 to 10 hours before transplanting to shield against early pests.
- Protective equipment: Wear chemical-resistant overalls, rubber gloves, vapor respirator mask, and protective goggles during spraying.
