Early prevention of gray mold in legume vegetables
With shorter sunshine hours and lower weather temperatures, ventilation time in greenhouses is gradually shortened, and the humidity in the sheds is increased. Beans and vegetables are used for flowering and flower buds are easy to invade gray molds, especially when they encounter cloudy days. Legume gray mold will occur seriously, so pay attention to early prevention. After the beans and vegetables enter the flowering stage, a large number of residual flowers will adhere to the soybean meal. Now, most vegetable farmers think that the gray mold in the shelter is very rare. Therefore, no attention is paid to prevention. The existence of these residues is the latter. A large area of ​​the disease has been buried with hidden dangers, leading to rotting phenomenon. For example, legumes, cowpeas, etc., which are easily detached from the pods, can be removed by cropping. However, care must be taken to pick up the residual flowers that fall on the leaves or vines to prevent gray mold from invading the flowers. After that, it harmed the stems. Like oily beans, petals are more sticky and do not easily fall off from the pods. Akira can't shake off the flowers from the plants. The vegetable grower can remove the spent flowers from the oil beans by picking flowers to avoid the invasion of gray mold. Dyed to rotten. When legumes enter the late growth stage, the old leaves of the lower part decay seriously and are also susceptible to gray mold. Therefore, attention should be paid to timely removal. When the gray mold is serious, the vegetable farmer can use 1200 times prophylaxis for prevention; it can also use 150-200 grams of sclerotia net per acre to control the smoked shed, but the time should not be too long. More than 8 hours is appropriate, the greater the amount of medication, the shorter the time required to smoke the shed.
