Techniques for prevention and treatment of tomato late blight in greenhouse
First, the characteristics of the disease: the source of flagellum subfamily fungus, the appropriate temperature for the onset of 18 ~ 22 °C. The blade edge is rotten, black stalk, and fruit hard. Low temperature and high humidity are the main conditions for the occurrence and prevalence of the disease. The dense greenhouses, large temperature difference, overcast rainy days, weak light, flooded irrigation, and lack of timely ventilation all contribute to the occurrence and prevalence of this disease. Second, the prevention and control methods: 1. Control the temperature, diligently release the wind. 2. Moisture control: The high-temperature short-term exhalation in sunny noon, and the cloudy morning for half an hour to exhale the fog. When the central diseased plant is found in the field, it should be sprayed and prevented in time. Closed greenhouse after spraying to increase temperature, can improve the control effect. The use of 68.75% silver-farina suspension agent 50-75 ml/mu evenly spray can achieve the dual effects of protection and treatment.
