Disease and pest control method for grapes

Abstract

The invention discloses a disease and pest control method for grapes. The method comprises a disease control method and a pest control method. The disease control method comprises the following steps of spraying an agent once every 5-10 days in the last flowering stage of grapes, and continuously spraying the agent for 5 times. The pest control method comprises the following steps of (1) after wilting of flowers of grape trees, spraying a compound agent of 3000-5000-time fluacrypyrim and abamectin for 2-4 times; (2) spraying a mixed liquid of 2000-time 4.5% beta-cypermethrin emulsifiable concentrate and 3000-time 20% sumicidin in May in the current year; and (3) spraying a mixed liquid of 2000-time 4.5% beta-cypermethrin emulsifiable concentrate and 3000-time 20% sumicidin in June in the current year. The methods disclosed by the invention effectively control the morbidity probability of grapes, so that the output of the grapes is improved and the income of fruit growers is increased.

Description

technical field [0001] The invention relates to a method for preventing and controlling grape diseases and insect pests. Background technique [0002] Most of the world's vineyards are distributed between 20-52 degrees north latitude and 30-45 degrees south latitude, most of which are in the northern hemisphere. The altitude is generally 400-600 meters. The altitude of Chinese grapes varies greatly between 30-43 degrees north latitude, about 200-1000 meters. The distribution height of grapes in Huailai, Hebei reaches 1100 meters, Qingxu, Shanxi reaches 1200 meters, and Shannan area of ​​Tibet reaches more than 1500 meters. Latitude and altitude are important factors that affect temperature and heat over large areas. [0003] In the case of similar terrain conditions, the microclimates of different slopes have obvious differences. Generally, slopes facing south (including due south, northwest and southeast) receive more light and heat, and the temperature is higher on week...

AI Technical Summary

Problems solved by technology

[0005] Although grapes have strong resistance to diseases and insect pests, they still occur from time to time before flowering and after fruiting, harming flower buds and young fruits, causing flower and fruit drop, which must be prevented in time

Grape plants are quite sensitive to pesticides. Some organophosphorus pesticides with strong permeability and systemic absorption and omethoate are prone to phytotoxicity and should not be used
