SOLID AGROFORMULATIONS FOR PREPARING NEAR MICRO-EMULSION AQUEOUS PESTICIDES

摘要

Disclosed are extruded pesticide granules that when mixed with water form a near micro-emulsion that is highly stable. The extruded pesticide granules include at least one pesticide active ingredient, a non-ionic surfactant, and a carrier, which is desirably urea powder or urea pearl. Processes for making the extruded pesticide granules are also disclosed.

主权项

1. A process for preparing an extruded pesticide granule comprising introducing urea into water to substantially wet the urea, introducing a substantially water soluble pesticide active agent into the wetted urea, adding a nonionic surfactant to produce a damp mixture, extruding the damp mixture to form an extrudate, and drying the extrudate to form the extruded pesticide granule.
