Shouguang Vegetable Station Agronomist replied: First of all, it is necessary to strengthen the ventilation of the greenhouse and reduce the air humidity. By increasing the amount of ventilation in the shed, the air humidity in the shed is controlled to be below 90% (hanging hygrometer in the shed, the suspension of the hygrometer should be 10-20 cm below the growth point), and the brown spot disease should be suppressed. Secondly, after watering in a sunny shed, the greenhouse can be immediately raised in temperature to increase the temperature in the shed to 40-45 degrees Celsius and last for 1-2 hours, using high temperatures to kill most pathogenic spores in the shed, and then Promptly conduct ventilation to reduce temperature and humidity. Once again, we must promptly eliminate the old leaves and diseased leaves in the lower part to reduce the source of infection. While focusing on physical prevention and control, it should also be combined with chemical control, can be used 70% grade Tuobu Jin 700 times mixed 60% Baitai (pyrazol oxime ester. Dessenlian) 1500 times liquid for prevention and treatment, the effect is better. BPAP20 AUTO / BPAP25 AUTO is a professional solution for OSA patient who have trouble tolerating CPAP device.
