Description

technical field [0001] The invention relates to grape cultivation technology, in particular to a method for preventing and controlling the pollution-free grape diseases and insect pests cultivated in the open field. Background technique [0002] Grape is one of the fruits that people like. It is not only delicious, but also has high nutritional value and is suitable for a wide range of people. In recent years, in the south of the Yangtze River in my country, the planting area of ​​grapes has also been continuously expanding. The current planting methods include greenhouse planting and open field planting, but if the grapes planted in the open field want to have no pesticide residues, they will adopt a pollution-free planting method. The area south of the Yangtze River is a typical rainy and humid climate area, with an annual rainfall of 1700-1800mm, more than 60% of which is concentrated in the grape growing period. Therefore, grape diseases are serious. Common diseases of ...

Problems solved by technology

Common diseases of grapes include anthracnose, black pox, gray mold, downy mildew, white rot, etc.; Improper use can easily lead to a reduction in yield and quality, or even damage to the garden. Therefore, the use of various pesticides is extremely important. If used improperly, it will not only affect the yield and quality of grapes, but also cause environmental pollution and fruit pollution, affecting human health

[0003] Traditional pest control uses many types of pesticides in each growth stage of grapes, and the configuration is quite cumbersome, which can easily lead to pesticide residues, cause environmental pollution, and affect food safety performance, and the effect of pest control is also unsatisfactory. The fruit is not plump and the yield is low
