Problems solved by technology

The bactericidal effect of copper hydroxide mainly depends on copper ions, which are absorbed by germinated spores. When the concentration reaches a certain level, the spore cells can be killed, thereby playing a bactericidal effect, but this effect is limited to preventing spore germination, that is, only Protective effects

Abstract

The invention provides a composition for control and elimination of crop diseases and pests. The active components comprise a compound (A), a compound (B) and a compound (C), wherein (A) represents the compound described by formula (A), (B) represents the compound described by formula (B), and (C) is selected from copper hydroxide or copper calcium sulphate. In the composition, the compound (A), compound (B) and compound (C) are in a weight ratio of 1-50:1-50:1-50, realizes organic combination of agricultural sterilization and insect killing, and the soil treatment can prevent the damage of fungal and bacterial diseases, soil pests and root nematodes simultaneously.

Description

Technical field [0001] The invention relates to a composition for preventing and controlling crop diseases and insect pests, and also relates to a method for preventing and controlling crop diseases and insect pests. Background technique [0002] In recent years, plant diseases caused by various plant pathogenic fungi, bacteria, and insect pests have become more and more serious. Since the 1980s, pesticide companies in various countries have successively developed a variety of high-efficiency chemical fungicides and insecticides, which greatly improved plant diseases and insect pests. The control effect. However, the continuous use of chemical pesticides has accelerated the resistance of plant diseases and insect pests, and the residues are high, causing pollution to the environment. [0003] Biological pesticides refer to the use of living organisms (fungi, bacteria, insect viruses, genetically modified organisms, natural enemies, etc.) or their metabolites (pheromone, auxin, nap...
