Application Of Insect Nets The Use Of Insect-Proof Nets To Artificially Construct Barriers To Reduce The Occurrence:

Application of insect nets;

The use of insect-proof nets to artificially construct barriers to reduce the occurrence of pests is of great significance for the development of pollution-free high-quality vegetables and cost reduction and efficiency.

Insect net function:

1. Insect control: After the vegetables cover the insect net, they can basically eliminate the harm of various pests such as cabbage caterpillar, diamondback moth, Spodoptera litura, and aphids. According to reports, the insecticidal net has an efficiency of 96% for cabbage cabbage, 95% for Plutella xylostella, 9% for Liriomyza sativa, and more than 90% for aphids.

2.  Disease prevention:

Viral disease is a catastrophic disease on a variety of vegetables. It is mainly caused by insects, especially aphids. Because the insect nets cut off the main route of transmission of pests, the infection of vegetable viruses is greatly reduced. According to the experiment, after covering the insect-repellent net, the prevention efficiency of tomato virus disease in spring reached 88.5%, and the yield increased by 24%. The summer cabbage virus disease prevention efficiency was 79%, and the yield increased by 22%.
