At present, autumn and winter tomatoes have begun to enter the color change period, but due to low ambient temperature and short sunshine during this season, the temperature inside the greenhouse is low, the air humidity is relatively high, and the light is insufficient. In addition, the greenhouse needs insulation, with little ventilation, and the degree of sealing is high. The problem of large air humidity in the shed is even more pronounced, which leads to the occurrence and prevalence of gray mold in tomatoes in fall and winter pods. The vegetable grower must strengthen the prevention of gray mold in order to obtain high yields of tomatoes.
The most important measures for controlling Botrytis cinerea are: First of all, do a good job in ventilation, light transmission, and dehumidification in the greenhouse, and keep the temperature not too low. Second, we must strengthen fertilizer and water management so that the plants grow stronger and prevent premature aging. Third, the petal and stigma adhering to the fruit are promptly removed. Fourth, the diseased plants and diseases should be cleared and destroyed in time. The following agents can be selected to control 50% fasting WP 1500 to 2000 times, or 40% polysulfide suspension 400 times, or 50% acetaminophen wettable powder 1000 to 1500 times, or 70% A. Chitobuzu 800 to 1000 times liquid and so on. Every 7 to 10 days spray once, continuous spray 3 to 4 times. It should be noted that pathogens are prone to drug resistance, and the same agent must not be used during a growing period. The above agents should be used interchangeably.
