Delpest T20E (Chlorpyriphos 20% EC) is a non systemic broad spectrum organophosphorus insecticide with contact stomach and respiratory action. It controls coleoptera, diptera, homoptera and Lepidoptera in soil and on foliage in over large number of crops including rice, cotton, oilseeds, pulses, vegetables and plantation.

Chlorpyriphos falls under toxicity Class II by WHO. Chlorpyriphos is registered in many countries. Other than field crops, Chlorpyriphos is also used to control household pests and mosquitoes.

It is non phytotoxic to most plant species when used at recommended dosages. It is compatible for tank mix with other insecticides and fungicides. In soil, Chlorpyriphos is degraded at a moderate rate. Chlorpyriphos is recommended in all Integrated Pest Management (IPM) and Insect Resistance Management (IRM) programmes.
