Embodiment 1

[0015] The present embodiment selects 6 kinds of pesticides with good effect on grape white rot bacteria, wherein: 3 kinds of chemical pesticides: 400g / liter flusilazole emulsifiable concentrate (Shanghai DuPont Agrochemical Co., Ltd.), 250g / liter prochloraz emulsifiable concentrate (Jiangsu Yixing Agrochemical Products Co., Ltd.), 250g / liter propiconazole EC (Swiss Syngenta Crop Protection Co., Ltd.), 3 kinds of biological pesticides: 0.1 million cfu / g Paenibacillus polymyxa fine granule (Zhejiang Tonglu Huifeng Biochemical Co., Ltd. company), 1×10 6 Pythium oligandrum WP (Czech Biological Preparations Co., Ltd.), 10% polyoxin B WP (Shaanxi Shanggelu Bioscience Co., Ltd.).

[0016] Screening of mixture formulations: the optimal formulation is screened by co-toxicity coefficient method. There are 5 mixing ratios of the two agents, namely 3:1, 2:1, 1:1, 1:2, 1:3; The way is as follows:

[0017] Mixture of chemical pesticides and biological pesticides: propiconazole + Paenibac...

Abstract

The invention discloses a coniella diplodiella prevention and control medicament and belongs to the technical field of plant disease prevention and control. The coniella diplodiella prevention and control medicament is specifically a pesticide composition formed by mixing a chemical pesticide and a biological pesticide according to the mass ratio of (1-3):(1- 3), wherein the chemical pesticide is one of flusilazole emulsifiable concentrate with the concentration of 400 g / L, prochloraz emulsifiable concentrate with the concentration of 250 g / L and propiconazole emulsifiable concentrate with the concentration of 250 g / L; the biological pesticide is one of paenibacillus polymyxa fine granules with the colonies number of 0.1 hundred million / g, 1*106 pythium oligandrum WP and 10% polyoxin B WP. According to the invention, since pesticides used for prevention and control of coniella diplodiella are combined, the effect on coniella diplodiella is improved greatly, unexpected benefits are realized and the yield of grapes can be increased greatly.

Description

technical field [0001] The invention belongs to the technical field of plant disease prevention and control, in particular to a medicament for the prevention and treatment of grape white rot. Background technique [0002] Grape white rot (Coniella diplodiella), also known as rot disease, is the main disease that causes fruit rot during the grape growing period. It occurs more commonly in vineyards, and the fruit loss rate is 10-15%. In severe years, it can lose more than 60%. , or even loss of harvest, the disease is quite serious in high temperature and high humidity seasons. The white rot of grapes grows small off-white dots, which are the pycnidia of the pathogen. The pathogen of grape white rot is caused by a fungus that invades grapes. [0003] The fungus of grape white rot survives the winter in the diseased tissue as conidia and mycelium. The diseased residues of fruit ears, leaves and branches in the topsoil of the orchard and on the trees can all become the prima...
