FAQ for LEO
How does Emamectin Benzoate in LEO work?
Emamectin Benzoate activates glutamate-gated chloride ion channels in insect nerve and muscle cells, causing irreversible hyperpolarisation, paralysis, feeding cessation, and death of bollworm larvae.

LEO is highly effective against American bollworm (Helicoverpa armigera), spotted bollworm (Earias spp.), and pink bollworm larvae — particularly targeting young early instar larvae in cotton.
At what pest stage should LEO be applied?
LEO is most effective when applied against early instar (young) bollworm larvae before they bore into cotton bolls. Monitor crops regularly and apply at first egg hatch for best control.
Is LEO suitable for use in IPM programs?
Yes, LEO's biological origin, unique mode of action, and low toxicity to many beneficial organisms make it an excellent component in Integrated Pest Management programs for cotton.
