Non-residual pesticide

Abstract

The invention relates-the technical field of pesticides, and concretely discloses a non-residual pesticide. The non-residual pesticide comprises, by weight, 2-4 parts of aluminum phosphide, 1.5-3 parts of sodium chloride, 0.5-1 part of potassium sulfate, 0.3-0.8 part of copper sulfate, 0.5-1 part of magnesium oxide, 0.2-0.5 part of calcium oxide and 90-95 parts of water. The non-residual pesticideis an inorganic pesticide prepared through optimizing the proportions of all components, and has the advantages of low cost, high safety, long-lasting effect ,no residual, and no influences on the crop yield.

Description

technical field [0001] The invention relates to the technical field of pesticides, and specifically discloses a pesticide without residue. Background technique [0002] Pesticides can be used to kill insects, fungi and other organisms that harm crop growth. The earliest pesticides used are dichlorvos and 3911, which can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and human bodies, so they were eliminated, and later switched to organophosphorus pesticides, such as dichlorvos, to replace the original pesticides. However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms. Contents of the invention [0003] The purpose of the present invention is to provide a pesticide without residue. By optimizing the ratio of each component, the prepared inorganic pesticide has the advantages of low cost, high safety, long-lasting effect an...
