Method for preventing and controlling fruit mulberry sclerotinia without pesticide residue

Abstract

The invention provides a new method for preventing and controlling fruit mulberry sclerotiniose without causing pesticide residue. According to different phonological areas of fruit mulberry planting areas or changes of small climate such as temperature and humidity and surrounding disease source environments, in combination with comprehensive situations such as the lowest winter temperature in the previous year, specific forms of fruit mulberry blooming stages are artificially divided into three stages, so as to thoroughly prevent and control the incurable disease, i.e., the fruit mulberry sclerotiniose by using the existing bactericides in a certain time span at a specific blooming stage without using special pesticide and guarantee that mature mulberry fruits are free of pesticide residue. The new method has a very great application value.

Description

Technical field [0001] The present invention relates to the technical field of plant diseases and insect pests prevention and control, in particular to a method for preventing and treating mulberry sclerotinia disease without pesticide residues. Background technique [0002] Fruit mulberry sclerotinia disease is the main disease that harms mulberry fruit. Due to the widespread presence of pathogens in nature and the particularity of air transmission, the existing conventional methods are basically ineffective for prevention and control. The existing general prevention methods are as follows There are several types: one is to remove the weeds around the mulberry trees in autumn and winter, and to plow the ground (to bury the pathogens deeply); the other is that the purpose of mulberry cultivation in China for thousands of years is to raise silkworms and to harvest mulberry fruits. The purpose is still in recent years. According to the introduction of textbooks for colleges and un...

Problems solved by technology

The above methods have been analyzed and demonstrated through many experiments, but the conclusions and consequences are disappointing: conventional methods to prevent and control sclerotia of fruit mulberry are due to the universality of the pathogen, the strong pathogenicity of the pathogen, and the rapid infection. No method can completely kill the pathogen

The above problems have restricted the large-scale promotion of fruit mulberry planting, so it is necessary to propose improvements
