Description

Fenamiphos is a systemic organophosphate nematicide and insecticide with a broad spectrum of activity. Its primary value lies in its ability to control soil-borne nematodes and certain insect pests, protecting the root systems of a wide variety of crops. This makes it a critical component in integrated pest management (IPM) programs for agricultural producers globally. Industries requiring this compound include agrochemical manufacturing, agricultural research, and formulation development for crop protection products.

Application

• As a key active ingredient in the formulation of nematicidal products for soil treatment.
• For the control of root-knot, cyst, and lesion nematodes in high-value crops such as bananas, citrus, grapes, and vegetables.
• Used in agricultural research and development for studying pest control efficacy and environmental fate of organophosphates.
• Incorporation into granular or liquid formulations for application in field and horticultural settings.
• Control of certain soil-dwelling insect pests alongside its primary nematicidal action.
• As a reference standard in analytical laboratories for quality control and regulatory testing of pesticide products.
