What is garlic mosaic disease?

What is garlic mosaic disease? How to prevent and cure garlic mosaic disease: 1. At the initial stage of the onset of the symptoms, intermittent yellow stripes appeared along the leaf veins, and then connected into the same yellow and green stripes, the plants were dwarfed, and the heart leaves of individual plants were surrounded by adjacent leaves, showing curly deformities, which could not be fully extended for a long time, causing the leaves to twist. The bulbs of diseased plants became smaller, or garlic cloves and fibrous roots decreased, and severe garlic cloves were stiff, especially during storage, and the yield and quality of garlic decreased significantly, resulting in species degeneration of garlic mosaic virus (GMV) and garlic latent virus (GLV). Sow poisonous bulbs and infect them immediately after emergence. Peach aphids and onion aphids are mainly used for non-persistent transmission in the field, and the virus is transmitted by juice friction. The management condition is poor, the occurrence of aphids is large, and the disease is serious in continuous cropping and adjacent cropping with other Allium plants. Because garlic adopts asexual reproduction and bulbs are used as sowing materials, the virus-carrying plants can be transmitted to the next generation with its vegetative cloves for a long time, so that the plants in the field are generally infected by the virus, and the virus reproduction coefficient is constantly expanded. make garlic degenerate and become smaller 2, strict seed selection of control methods, establish original seed base as far as possible, use garlic bulbs in light disease areas as seeds, reduce the rate of virus-carrying bulbs. Garlic apical meristem can be cultured in vitro to remove virus from garlic bulb and form virus-free garlic seed. Avoid adjacent or continuous cropping with green onions, leeks and other crops to reduce natural transmission of virus in the field. Spraying insecticides to control aphids in the garlic field and surrounding crops, preventing repeated infection of virus, strengthening fertilizer and water management, avoiding premature senility, and improving plant disease resistance. at the initial stage of the disease, 1.5% Zhixianling EC or 1000 times of 20% virus A wettable powder was sprayed, antivirus No. 1 water agent 250 times 300 times, once every 10 days.
