Viral disease is the second largest disease of Passion fruit, which may occur during the whole growth process of Passion fruit. Because of the poor control effect of the disease after the virus disease of Passion fruit, many netizens who planted passion fruit call or WeChat consult Baixiang Can virus disease be controlled? What kind of medicine control does passion fruit have? The following cultivation and cultivation network will be briefly introduced for the reference of netizens. The main symptoms of passion fruit virus disease 1. Passion fruit debilitation: it is characterized by growth retardation and plant dwarfing. The leaves are dark green, rough, small, distorted, deformed, folded, yellowed and veined. Production is seriously affected. 2, passion fruit mottled disease: the main feature is the leaves in the light, thick green mottled symptoms. At the mottled, it is often concave. The viral disease does not appear to have a serious effect on growth. As long as it is managed properly, even if there is this disease, there is still a harvest. 3. Passion fruit mosaic: There are typical mosaic symptoms, but growth and yield are not seriously affected. 4. Passion fruit maculopathy: There are yellow or gray-yellow spots on the leaves, the veins also have yellow spots and are transparent, and the leaves are curled and deformed. The fruit has round or polygonal concave lesions, and its internal tissues are necrotic. This viral disease differs from mottled disease in its host range. It can infect and produce systemic symptoms. 5, Passionflower Wrinkle: The most typical symptom is that the blade folds from the edge to the inside. On the apical young leaves, the inward curling results in wrinkles, accompanied by thickening of the veins, and the stems are also twisted, thickened and ribbed, and once infected, growth is immediately blocked. 6, passion fruit lignification virus disease: the performance of the leaves light color, showing mosaic symptoms, slightly shrinkage phenomenon. The fruit is small and deformed, hardened, the skin is thick, the fruit cavity is reduced, and the flower is sterile. The diseased plant is dwarfed and has poor growth and development. Passion fruit virus disease control measures 1, usually found in the seedling stage virus disease only the whole seedlings directly destroyed, if it is in the middle and late results, you can only control the disease, and then destroy the fruit. 2. When the passion fruit is infected with the virus, the leaf reaction is not as fast as it is. When the leaves react, it is already very serious. If it is a wooden virus, the impact on the quality of passion fruit is the biggest, and this must be resolutely eradicated. 3. Select non-toxic healthy seedlings, control from the source, disinfect the soil before planting, and choose the cultivated land near the orchard that has not been planted with pepper, tobacco, solanacea, melon and other crops as the passion fruit planting area. 4, strengthen cultivation management, scientific pruning, cut off sick branches and dense branches, adjust the ventilation and transparency in the garden, timely clean up and burn diseased diseased leaves, reduce the number of pests and diseases, pruning scissors is best to pruning each fruit At the end, a portable flamethrower is used for disinfection and another plant is trimmed. And timely remove the diseased plants, and use lime to disinfect. 5, in the passion fruit seedling period 10 to 15 days spray to kill aphid and other drug-borne vectors, inhibit the occurrence of viruses, while paying attention to the prevention and control of underground pests. Conditionally, the agent is sprayed regularly from the seedling stage to continuously increase the ability of the passion fruit plant to inhibit the virus. 6. After eradicating the virus-infected plants, the virus will still form a protein shell in the host to sleep. The orchard that needs to be replanted must be re-planted after more than ten days of turfing and disinfecting the original planting hole. 7. After the occurrence of mosaic virus disease, the whole plant can be sprayed with 1000-1500 times of lobular yellow, or 1500-2000 times of virus spirit, or 2000-2500 times of bacterium. Or use the scorpion venom, ie, octylamine morpholinium to control. 8. Pay attention to the plants of Passion fruit during the cultivation of Passion fruit. It is found that the growth point of the passion fruit plant is atrophy, and the leaves are chlorotic and yellow. When the new leaves are curled and elongated, the leaves should be sprayed 600 times 0.5%. Proteoglycan, 800 times 1.8% octosamine acetate, 1500 times 0.001% natural brassin, 0.1% zinc sulfate, 1500 times 10% thiamethoxam mixture for prevention and treatment. Spray the leaf surface once every 7~10 days, spray it continuously for 2~3 times, spray all the stems and leaves evenly, and start to drop the drops of water. In case of rain water granules within 4 hours after spraying, it should be re-sprayed once to improve the control effect. In this way, it is possible to weaken the activity of the virus, inhibit the propagation of the virus, kill the virus and spread the virus (the virus of the passion fruit mosaic virus is transmitted by pests such as aphids, whitefly, thrips, etc.). It can restore the normal growth of diseased plants and prevent the spread of viruses to other healthy plants. It can also enhance the ability of plants to resist viruses and reduce the incidence.
