Grape disease and pest control method

Abstract

The invention discloses a grape disease and pest control method which comprises a disease control method and a pest control method. The disease control method includes the steps: spraying insecticidesonce every 5-10 days and continuously spraying the insecticides for 5 times at a flowering final stage of grapes. The pest control method includes the steps: (1) spraying a complex agent of 3000-5000-fold fluacrypyrim and abamectin for 2-4 times after grape vine blossoms fall; (2) spraying mixed liquid of 4.5% 2000-fold efficient cypermethrin emulsifiable concentrate and 20% 3000-fold sumicidin in May in the same year; (3) spraying the mixed liquid of the 4.5% 2000-fold efficient cypermethrin emulsifiable concentrate and the 20% 3000-fold sumicidin in June in the same year. Grape incidence probability is effectively controlled, grape yield is increased, and 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
