Question: The reader of Yufei Township said that he had planted 3 mu of spring watermelon this year. After the melon seedling came out, he found that the base of the stem of the melon seedling appeared yellow-brown rectangular lesions, and then the diseased seedlings wilted and died. Ask what disease this is, how to prevent it? Yan Jindong: According to the readers' judgment, this is a watermelon blight. Water blight, also known as dead seedling disease, is one of the common diseases of watermelon seedlings. Freshly emerged seedlings and late-stage melon seedlings can develop, but they mainly occur in the middle and late seedling stages. After seedlings were sowed, the seedlings were affected. The roots of the roots showed yellow-brown elongated or elliptical lesions. At the early stage of disease, the diseased seedlings wilted during the day and returned to normal at night. The stem base then dried up and contracted. The diseased seedlings quickly wilted and died. However, the diseased plants were not easy to fall down and were in standing and wilting. Severe onset often results in death of seedlings. Humidity, excessive sowing, poor lighting, poor ventilation, poor drainage, poor soil moisture, poor ventilation, and extensive management of the disease are heavy. In the early years of the year, the incidence of cold and rainy weather was high in early years. Control methods: 1. Agricultural control. To reasonably control the temperature and humidity of the seedbed, it is necessary to take a small nap and lightly pour. Pay attention to timely and moderate ventilation and ventilation; add emphasizing differences to timely remove diseased seedlings and dead seedlings. 2. Chemical control. Optional 25% azoxystrobin (Amisida) 1500 times, or 95% hymexazol 4000 times spray or soil treatment. Bump keys are specially designed with a specific cutting technique that can sidestep the security mechanism in the average tumbler and pin lock. Bump keys are designed to exploit a loophole that`s built into most pin and tumbler locks. You see, the pin stacks in a pin and tumbler lock are spring loaded to keep the cylinder in place so that it can only be turned with the right key.
