Abstract

The invention discloses a pesticide composition containing ethirimol and thiophanate-methyl. The composition comprises common additives, ethirimol and thiophanate-methyl, wherein the weight-part ratio of ethirimol to thiophanate-methyl is 10:1-1:20, and the weight percentage of the total weight of ethirimol and thiophanate-methyl in the pesticide composition is 10 to 90 percent. The additives are one or more of solvents, emulsifiers, wetting agents, stabilizers, dispersants, thickeners, pH regulators, defoamers, antifreeze and filling agents. The pesticide composition with ethirimol and thiophanate-methyl needs to be used before or at an early stage of the occurrence of diseases. The composition has the preventing-controlling effect obviously improved in comparison with that of single agents, and reduces the use dosage of pesticide so as to reduce the influence of the pesticide on environment as well as drug cost. The composition is particularly used to prevent and control powdery mildew of apple trees.

Description

technical field [0001] The pesticide composition involved in the present invention uses pyrimol and thiophanate-methyl as active ingredients, and is used for preventing and treating plant diseases in agriculture, especially for preventing and treating powdery mildew of apple trees and the like. Background technique [0002] The growth and development of crops in nature has never been very smooth or easy to succeed. It will encounter the invasion and destruction of various diseases and insect pests, especially fungal diseases. There are many types and serious damage. For a long time, chemical control is the The main effective means of disease control. However, due to single and unscientific drug use in recent years, many pathogenic bacteria have developed resistance to the currently used pesticides. Powdery mildew is a worldwide disease that occurs widely on many important crops, causes serious damage, and is difficult to control. Production brings huge losses. Powdery mild...
