Phenex 50 is a non-systemic insecticide from the organophosphorus group, formulated with Phenthoate 50% EC. It offers broad-spectrum control against both chewing and piercing-sucking insects in multiple crops. With its quick knockdown action, Phenex 50 delivers fast and effective results, especially against bollworms, caterpillars, thrips, and caseworms.

Its strong pungent smell helps deter adult insects from laying eggs. Phenex 50 works by inhibiting cholinesterase, a vital enzyme in the insect nervous system, leading to paralysis and death.
