Introduction

Pyriproxyfen 98% TC is a highly effective insect growth regulator (IGR) belonging to the pyridine-based juvenile hormone analog class. It is widely used to control various insect pests by disrupting their normal growth and development processes.

Pyriproxyfen works by mimicking insect juvenile hormones, preventing immature insects from developing into reproductive adults. This mechanism effectively breaks the pest life cycle, leading to long-lasting population suppression.

As a high-purity technical material appearing as a white to light yellow crystalline powder, Pyriproxyfen provides strong residual activity and excellent selectivity, making it particularly suitable for integrated pest management (IPM) programs.

The 98% TC grade is primarily intended for industrial formulation into commercial insecticide products such as emulsifiable concentrates (EC), suspension concentrates (SC), and water-dispersible granules (WDG).

Product Feature and Application

As a 98% technical concentrate, Pyriproxyfen provides highly effective insect growth regulation activity by disrupting the hormonal system of insects.

Its primary function is to prevent immature insects from developing into adults, effectively breaking the pest reproduction cycle and reducing population growth.

Typical applications include the control of whiteflies and scale insects in cotton, vegetables, and fruit crops, often applied at 50–150 g/ha depending on pest pressure and crop type.

Pyriproxyfen can be used alone or combined with other insecticides to broaden the control spectrum and enhance pest management strategies.

This 98% TC technical material is intended for industrial formulation into end-use products including:

EC (Emulsifiable Concentrate)
SC (Suspension Concentrate)
WDG (Water-Dispersible Granules)

Its stable physicochemical properties and excellent compatibility make it an ideal raw material for modern insecticide formulations.
