Problems solved by technology

Chemical control is effective, but it will cause pesticide residues and damage the ecological environment, which does not meet the current people's pursuit of healthy food
Common biological agents, due to their long development cycle, high price, slow effect and easy to be affected by environmental factors, limit the promotion and use of biological agents

Embodiment 1

[0038] A method for preventing and controlling the powdery mildew of the winter fruit grape 'Guipu No. 6' cultivated with two harvests. The germination period of the first batch of grapes of the 'Guipu No. 6' grape is from early to mid-March, and the flowering period is in early April. The fruit ripening period is from the first ten days of July to the middle ten days of July; the second ten days of a month fruit germination period is in early September, the flowering period is in early October, and the fruit ripening period is in late December, including the following steps:

[0039] (1) before the 2nd stubble fruit sprouts, spray lime sulfur mixture 100 times;

[0040] (2) When the 2nd stubble fruit unfolds leaves, spray Bacillus amyloliquefaciens / Bacillus subtilis, consumption is 100g / mu;

[0041] (3) Spray 2000 times of alkenoyl pyrazolate before and after flowering of the second fruit; every 5 days, spray Bacillus amyloliquefaciens / Bacillus subtilis; every 12 days, spray...

Abstract

The invention relates to a method for preventing and controlling powdery mildew of winter fruit grape 'No.6 Grape' cultivated in two harvests, and belongs to the field of plant powdery mildew prevention and control. The method for preventing and controlling powdery mildew of winter fruit grape 'No.6 Grape' cultivated in two harvests includes the following steps: (1) spraying a lime sulfur agent before a second fruit crop sprouts; (2) spraying a biological preparation when the second fruit leaves are spread; and (3) spraying diniconazole ester, mineral oil concentrate, a compound agent of aminooligosaccharide and alternaria protein, phenylazoxystrobin and a biological agent in sequence before and after the flowering of the second fruit crop, and timely adopting a compound agent of auxiliary agent alkyl aryl polyoxyethylene ether and Butanedioicacid. The method adopts a combination mode of biological preparations and organic preparations to prevent and control powdery mildew, reduces the infection probability of powdery mildew, reduces the use of organic chemical pesticides with larger pesticide residue risks to the greatest extent, and meets the requirements of national food safetystandards.

Description

【Technical field】 [0001] The invention relates to the field of plant powdery mildew prevention and control, in particular to a method for preventing and controlling the powdery mildew of winter fruit grapes cultivated with two harvests 'Guipu No. 6'. 【Background technique】 [0002] Grape powdery mildew can damage grape leaves, fruits, vines, etc. Its young tissues are most susceptible to infection. The pathogen is Uncinulanecator (Schw.) Burr., which belongs to the subphylum Ascomycota, and its conidia are spread to the surface of the host by wind. The conidia of powdery mildew pathogen can be ruptured due to water absorption, so that they cannot germinate. Therefore, rainy weather is not conducive to the germination of powdery mildew conidia and mycelial growth. Rain-shelter cultivation is the main cultivation method in Guangxi grape producing areas. The rain-shelter cultivation mode reduces the factors that inhibit the prevalence of powdery mildew, and artificially change...
