Abstract

The present invention is directed to a pesticidal composition of a water-soluble pesticide and processes for its manufacture. More specifically, the invention relates to a soluble granule (SG) pesticidal formulation comprising a water-soluble pesticide and a water-soluble filler. The present invention provides a pesticidal formulation with efficacy equal to the corresponding liquid formulation, yet with improved handler safety, such as lower eye irritation.

Description

[0001] This application is a divisional application of the application titled "Pesticide Preparation" with an international filing date of November 4, 1996 (international application number PCT / US96 / 17640) and a national phase application number of 96199398.7. technical field [0002] The invention relates to a pesticide composition containing a water-soluble pesticide and a preparation method thereof. More specifically, the present invention relates to soluble granule (SG) formulations containing a water-soluble pesticide and a water-soluble filler. Background technique [0003] Emulsifiable concentrate (EC) household formulations of pesticides are well known in the art. These formulations usually contain, in addition to the pesticide, emulsifiers and dispersants to form a homogeneous solution. However, since these agricultural formulations are liquid, they have many disadvantages. In particular, liquid pesticides must be used with care to minimize safety concerns, especi...
