In the recent harvest of wheat, Changchun vegetables were replaced, and some plots of locusts lost their “homeland†and they had to find new places to eat. Although locusts on crops such as locusts and wheat crops do not belong to the same category, and damage crops are different, locusts have the property of tentative feeding, which can lead to large-scale spread of viral diseases while searching for feeding crops. Therefore, the current period of time is a peak of viral disease.
Cut off the transmission of the virus disease mainly through the aphids, whitefly and other transmission insects. Cutting off the transmission route of the virus is an effective measure to prevent and cure viral diseases. Strictly prevent pests, set up insect-proof nets at the air outlet, and hang yellow sticky board inside the shelter to prevent pests from invading. When pests are found, they are regularly sprayed with imidacloprid, acetamiprid, and buprofezin to kill poisoned pests. Pay attention to agricultural management. When performing operations such as picking and snoring, try to avoid contact between the juices of the plants and reduce the risk of virus transmission.
Improve plant resistance The plants themselves have a certain resistance to viruses. The more robust the plants are, the stronger the resistance to the virus is. Therefore, the vegetable growers must strengthen the management of the greenhouses so that the plants grow robustly. On the one hand, provide sufficient nutrition for the plants, apply enough base fertilizer, and reasonably apply fertilizer after planting. Use lighthouse, Haolipu, Fangrun and other water-soluble fertilizers with Genjia, Apollo 963, etc. Spraying trace elements such as zinc fertilizers and amino acids, nucleotides, and mushroom proteins to supplement leaf nutrients and improve stress resistance. On the other hand, we must control the temperature and humidity.
There are no specific drugs for the prevention and treatment of viral diseases, which can prevent them from being treated. Virus A, Ningnanmycin, alizarin lactone, zinc fertilizer, etc. can be used to increase plant resistance and inhibit virus disease.
