Active chemical composition and neurotoxic mode of action
Fendal contains Phenthoate 50% EC (emulsifiable concentrate), an active organophosphate compound with pronounced contact and stomach action.
It functions by irreversibly inhibiting the acetylcholinesterase (AChE) enzyme in insect nerve junctions. This disrupts nerve signal transmission, causing continuous neuromuscular excitation, paralysis, and rapid mortality of feeding pests.
- Active chemical: Phenthoate 50% EC.
- Chemical family: Organophosphate (Acetylcholinesterase inhibitor).
- Ovicidal action: Possesses ovicidal properties that kill freshly laid insect eggs, breaking successive pest generations.
Target crops and approved pest coverage
Fendal is registered in India for broad-spectrum insect management across cash crops, cereals, oilseeds, and pulses.
It is widely used in cotton for controlling bollworms and in rice for managing stem borers and leaf folders.
- Cotton: Spotted bollworm, American bollworm, pink bollworm, and jassids.
- Paddy (Rice): Yellow stem borer, leaf folder, and gall midge.
- Pulses (Pigeon pea, Chickpea): Pod borer complexes.
- Oilseeds (Groundnut): Leaf miner and Spodoptera foliage caterpillars.
Application dilution, coverage, and personal safety
Apply Fendal at the initial appearance of insect pests or when threshold levels indicate active larval feeding.
Ensure thorough coverage of upper and lower leaf surfaces, stems, and fruiting bodies using calibrated knapsack sprayers operated at label-prescribed dilutions.
- Foliar wetting: Ensure complete canopy coverage using fine hollow cone spray nozzles.
- Personal protective equipment: Wear rubber gloves, protective goggles, face shield, and protective overalls during preparation and spraying.
- Environmental caution: Highly toxic to aquatic organisms and honeybees; avoid spraying near water bodies or during peak pollination.
