Garlic has fewer diseases than other vegetables. However, in recent years, a relatively rare new type of disease, a garlic leaf blight, has appeared in the garlic area, and the onset is fierce and the damage is serious. Once this disease occurs, it can cause a significant reduction in production. First, the symptoms identify the disease mainly damage leaves, leaf sheath. There are two types of leaf lesions: the first is a tip type, which mainly occurs in the initial stage of infection. The tip of the leaf is dark brown, and many deep purple-brown parallel stripes are formed on it, and the serious lesions spread to the whole leaf. One-third to four-fifths, or total dry dead leaves; Second, leaf-spot type, early onset of short strips of small leaching spots on the leaves, slightly sag, after the lesion quickly expanded into a shuttle to Long oval, tissue necrosis, depression, mostly purple brown, darker central color, and some milky white. At the time of the great event, he died after 10 to 15 days. Second, the occurrence of the characteristics of pathogens conidia and mycelium overwintering on the sick body, is a fungus fungus. In addition to invading garlic, this strain can also infect green onions and onions to cause purple spot and infecting day lily to cause leaf blight. With or without wounds, the bacteria can infect garlic. It usually begins in late April and enters the peak of onset in late May and late. This period coincides with garlic pregnancies and convulsions. If there are more than 12 mm of continuous rainfall more than 3 times, it can easily cause a pandemic of the disease. Third, comprehensive prevention and control technology 1. Strict selection of seeds before sowing, moldy, moth-eaten, yellowing soft garlic will be eliminated. 2. After the harvest of the previous crop, the cultivator ploughs and ploughs it to a depth of about 20cm. After the ploughing, the sunbathe is about 15 days. In the event of an early fall, it is not appropriate to bathe in the fortress. Grab the plough and plough the plough, and take care of it. 3. The garlic will be promptly removed from the body after harvest, and burned or buried deeply to reduce the source of the disease. 4. To formulate fertilization, avoid excessive application of nitrogen fertilizer, increase phosphorus and potassium fertilizers, apply sufficient maturity basal fertilizer to increase plant resistance. 5. Properly dense planting, take a row spacing of 20cm, plant spacing of 9 ~ 10cm, planting 35,000 ~ 38,000 plants per acre is more appropriate. 6. Chemical control: spraying 50% of quick-acting or acetaminophen wettable powder 1000 times, or 50% of carbendazim wettable powder 1000 times in the initial stage of disease, once every 7 days, and even spray 2 ~3 times, stop using drugs 3 days before harvesting.
