Abstract

The invention belongs to the field of pesticide preparations, and particularly provides a special additive composition WP-03 for wettable powder. The additive composition comprises the following components in parts by weight: 10-60 parts of polycarboxylate SD-816, 10-30 parts of sodium dodecyl benzene sulfonate, 10-50 parts of sodium lignin sulfonate, 10-30 parts of cocamidopropyl betaine and 10-50 parts of white carbon black. The special additive composition WP-03 can solve the problem that the wettability of wettable powder is poor and the suspension rate is low, the fluidity and the anti-caking property of the preparation can be improved, and the prevention and treatment effects of active ingredients can be enhanced.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and in particular relates to WP-03, a special additive composition for wettable powder. Background technique [0002] In the process of agricultural pest control, most of the conventional spraying pesticide liquids currently used, when the liquid sprays on the surface of the crops, only 20-30% of the liquid is spread on the leaves of the crops, and the other 70-80% of the liquid Due to the poor performance of spreading and systemic absorption, large droplets roll down on the field, resulting in the utilization rate of pesticides, the increase in the amount of pesticides used per mu, the low efficiency of pest control, and the pollution of the environment. [0003] Pesticide wettable powder is a dosage form with a long history, relatively mature technology and convenient use in pesticide preparations. It is composed of pesticide raw materials, surfactants (wetting agents, dispersants, etc.), ...
