Environment-friendly floating agrochemistic formulations for rice field and method of producing the same

Abstract

The invention discloses the composite of an environment-friendly rice flotable agricultural chemical preparation and a novel manufacture process thereof, which belongs to the field of farm chemical. The preparation is formed by compounding 0.1 to 50 percent of a weed killer, an insecticide, a fungicide or plant growth regulator active ingredients, 0.1 to 30 percent of a micropore sustained release agent, and 99.8 to 20 percent of a floatble carrier according to mass percentage. The preparation can effectively save the active ingredients by more than 70 percent, and can be directly applied on the surface of rice paddy field. The preparation has the characteristics of low cost, high efficacy, lasting drug action, safety, convenient use and so on, and is an environment-friendly agricultural chemical preparation.

Description

Environment-friendly paddy field floating agrochemical preparation and preparation method thereof technical field The invention belongs to the field of pesticide manufacture. The invention relates to a paddy field herbicide, an insecticide and a fungicide, a plant growth regulator and a preparation method. Background technique At present, the dosage forms of rice field agrochemical preparations mainly include: wettable powder, granule, microgranule, soluble powder, suspension concentrate, emulsion, effervescent agent, etc. These preparations have high main ingredient content and low utilization rate of active ingredients. The preparation process requires ultrafine pulverization, granulation, or emulsification with a large amount of solvents. The process is complex, high energy consumption, high cost, and large pollution. For this reason, the inventor invented a kind of agrochemical preparation in the patent No. 98112697.9 patent, promptly utilizes the composite active in...
