The occurrence of gray mold disease is more common in wintering greenhouses such as tomatoes, peppers, eggplants, and cucumbers. Botrytis cinerea is caused by the infection of Botrytis cinerea. Flowers, fruits, leaves and stems can be infected. Especially in the flowering period and fruit setting period, the damage is most serious. The pathogenic bacteria invade from the debilitating petal or stigma and gradually expand to fruit. The stalk and fruit form a thick layer of gray mold on the skin. The incidence of leaves, mostly from the tip of the leaf, forming a V-shaped lesions. Botrytis cinerea growth temperature range: 2 °C -31 °C. Weak light, humidity above 90% often causes high incidence of disease and is difficult to control. The key to the prevention and control of this disease is the control of humidity and early prevention. First, the control of humidity is fundamental. One is sorghum cultivation with drip irrigation under the membrane. The second is to be smooth and slightly ahead. In order to ensure that the amount of watering is slightly smaller, the impact of membrane water can be resisted and the problem of the difficulty of dehumidification in front of the shed cannot be solved. The third is the sunny morning pouring, control of water. The amount of water should be small and the control should be accurate. Water should be poured in sunny mornings. Do not water in rainy days. Rinse and heat after watering. Second, missed the drug. When adding tomato to prevent flowering, it can be coated with 0.1% speeding or acetaminophen. Cucumber was sprayed or immersed in flowers by adding 2.5% of Shiloh's 200-fold suspension seed coating agent. Third, the early onset of disease control. Clean up the body and aerosol use. The first is to promptly remove diseased leaves, diseased flowers, diseased fruits and other tissues into plastic bags and take them out of the greenhouse for burying. Next, use 20% of Procymidone smoke agent 80-100 grams or 45% of chlorothalonil smoke agent 200-250 grams per acre, place it at 5-6 points, and light it in a closed shelter overnight to smoke once every 7 days. Even smoked 2-3 times, there is a good control effect.
