Problems solved by technology

Because sclerotinia occurs frequently and is popular in the middle and late stages of rapeseed growth, specific pesticide dosages and labor intensity are required to allow pesticides to reach the damaged parts (stems and branches of rapeseed); and another problem that cannot be ignored is Sclerotinia sclerotiorum There is a very high risk of long-term large-scale use of a single type of pesticide

Abstract

The invention belongs to the technical field of biological pesticide, in particular to screening and identification of a coniothyrium minitans strain with strong parasitism and saprogenicity on sclerotinia sclerotium and an application thereof in a microorganism agent. The coniothyrium minitans ZS-1SB strain is preserved in China Center for Type Culture Collection (CCTCC) with the preservation number being CCTCC NO: M209114. The invention also discloses an open-type solid fermentation cultivation method of the microorganism agent and an application of the coniothyrium minitans ZS-1SB microbial inoculum in the prevention and treatment of sclerotinia of colza. The microorganism agent of the invention has excellent biological prevention effect on plant fungous diseases such as sclerotinia rot of colza and the like.

Description

A biocontrol fungus ZS-1SB for preventing and treating sclerotinia and its preparation method and application technical field The invention relates to the technical field of microbial pesticides, in particular to a Clamella shield strain with biocontrol potential for Sclerotinia sclerotiorum and a semi-open solid fermentation culture method and application thereof. Background technique Sclerotinia sclerotiorum (Lib.) deBary can infect more than 540 kinds of plants in 64 families, including major oil crops such as rapeseed, soybean, and sunflower, and important vegetable crops such as lettuce, Chinese cabbage, celery, and carrots. cause sclerotinia in a variety of plants. Since no planting resources with obvious disease resistance have been found so far, and no disease-resistant varieties can be used, the sclerotinia caused by it is still a worldwide problem in agricultural production. At present, chemical pesticides are mostly used for control. For example, spraying chemi...
