Cut off the virus transmission method The viral disease is mainly transmitted by insect transmission insects such as aphids and whiteflies. To cut off the transmission route of the virus, an insect net should be set at the air outlet, and a yellow sticky board is suspended inside the shelter to prevent pest damage. When pests are found, they are sprayed with imidacloprid, buprofezin, etc. in time to kill poisoned pests. When carrying out operations such as picking and snoring, try to avoid contact between the sap of the plants and reduce the risk of virus transmission.
Cultivate strong trees and increase plant resistance The plants themselves have a certain resistance to viruses. The stronger the plants are, the stronger the resistance to the virus is. Therefore, the vegetable growers should strengthen the management of the greenhouses so that the plants can grow robustly. On the one hand, provide sufficient nutrition for the plants, apply enough base fertilizer, and reasonably apply fertilizer after planting. All-water-soluble fertilizers can be used together with roots, Apollo 963 roots and other roots to promote roots, foliar spray of zinc and other trace elements and Amino acids, nucleotides, and mushroom proteins supplement leaf nutrition and improve stress resistance. On the other hand, control the temperature and humidity. For the characteristics that virus diseases are easy to occur under high temperature and drought conditions, the following regulation and control work should be done in the management of greenhouses: ground water or sprinkler irrigation facilities can not only increase the humidity in the greenhouse, but also reduce the greenhouse temperature. Timely cover the shade net, reduce the greenhouse temperature, but also pay attention to take measures to reduce the night temperature within the shed, reduce nutrient consumption and inhibit the occurrence of viral diseases.
Drug control can be used virus A, ningnanmycin, with brassinolide, zinc fertilizer, etc., to improve plant resistance and inhibit the occurrence of viral disease.
