How to prevent and cure strawberry virus disease?

What causes strawberry virus disease? How to prevent and cure strawberry virus disease? We also ask experienced netizens to introduce that when strawberries grow, the veins of the leaves are slightly transparent, the leaves are of different shades, forming mottled flowers and leaves, and when the disease is serious, the leaves are uneven and wrinkled, at the same time, the diseased plants grow slowly and become seriously dwarfed. strawberry fruit will also appear serious deformed symptoms, and there will be mosaic, yellowing, necrosis, deformity and other manifestations on the same plant. This is strawberry virus disease. Strawberry virus disease is a kind of disease that harms strawberry production seriously, loses a lot and is difficult to prevent and control, so the farming network collates the causes and control methods of strawberry virus disease, which are listed in detail below for netizens' reference. First, the cause of strawberry virus disease: the source of strawberry virus disease can not survive the winter on the diseased body. Strawberry virus disease can only be parasitized on strawberries still alive in winter, on strawberries planted, perennial weeds and strawberry plants as hosts to survive the winter. In the following year, the surviving hosts were transmitted by insects, contact and wounds, and were transmitted through pruning and other sites that caused wounds in strawberry plants. Aphid feeding is also one of the main ways of transmission. The high temperature and drought environment is suitable for the prosperity and occurrence of strawberry virus disease. If the management of strawberry orchard is extensive, the occurrence of weeds in the field is more serious. 2. Prevention and control methods of strawberry virus disease: 1. Select resistant strawberry varieties: different strawberry varieties have different resistance to virus disease. In order to reduce the occurrence of virus disease or slow down the harm, varieties with strong resistance to virus disease should be selected for cultivation. Japan 99, America 3, Niufeng, Jingxiang and Jingxiang are all varieties with strong resistance to virus disease. Method 2. Strengthen the management of strawberry orchard: the high and low soil fertility directly affects the growth of strawberry plants. therefore, whether in open field or in protected cultivation, sufficient organic fertilizer should be applied to provide a better growth environment for strawberry plants. At the same time, weeding in ploughing should be strengthened in time, aphids should be killed in time, and the transmission of strawberry virus disease should be reduced. Method 3. Timely control of disease-carrying pests: aphids are an important carrier of strawberry virus disease. The cultivation techniques of strawberry interplanting muskmelon in greenhouse should pay attention to the control of aphids. First of all, we can make use of the aphid avoidance, set up anti-aphid yellow board to lure aphids, silver gray film to avoid aphids, can play a better control effect. When raising strawberry seedlings, it is necessary to kill aphids, lice and thrips in time. Strengthening the anti-insect net configuration of strawberry greenhouse is the most effective measure to block the transmission of virus. Before transplanting strawberry seedlings, irrigating the seedlings with 25% Aktai water dispersible granules will have a long-term effect on the prevention of aphids and whitefly for more than 30 days. It is a better way to prevent aphids from spreading virus. 2-3 days before transplanting, the seedlings were sprayed with 1500-2000 times solution of 25% Aktai water dispersible granules, and the solution also penetrated into the soil in addition to the spray leaves. About 2 kilograms of spray liquid per square meter of seedbed. It has a good effect on the control of aphids and virus diseases. Method 4. Using medicament to control strawberry virus disease: 25% Aktai water dispersible granule 2500-5000 times, or 10% imidacloprid wettable powder 1000 times, or 10% anti-lice Ding wettable powder 1000 times, or 2.5% green kungfu water 1500 times, or 1.5% Boshanling EC 1000 times, or 30% virus star wettable powder 1000 times. It has a certain control effect on strawberry virus disease. Methods of potted strawberries Prevention and Control of Strawberry anthracnose
