Tomato gray mold suffers from heavy rain or persistent low temperature and high humidity, resulting in reduced yield and quality of tomatoes.
When the leaves develop, the tip of the leaf expands in a “V†shape from the tip of the leaf; when the stem becomes infected, it expands into a long oval or a long stripe; when the humidity is high, a layer of brownish brown mold appears on the lesion; when it is severe, it causes the diseased part to die; The younger victims were heavier. They first started developing from the stumps, and then developed towards the fruit, causing soft rot of the young fruit. On the mature fruit, the lesions were stained and gray-white, and later on the fruit surface were covered with gray mouldy material.
Prevention of Botrytis cinerea should pay attention to the following points:
(1) Choose sunny days and do a good job in timely ventilation and ventilation of protected areas to reduce the humidity in the greenhouse. Watering should be carried out in the morning, and watering should be controlled at the early stage of disease. (2) Remove diseased leaves, diseased fruits, diseased branches, bring them out of the field and concentrate deeply or burn them, and sprinkle some lime disinfection around the diseased plants. In addition, high-efficiency foliar fertilizers such as dipotassium phosphate or spray-applied fertilizer can be used for topdressing to promote robust growth of plants and increase disease resistance. (3) The tomato seedlings were sprayed with 50% Suo Ke Ling WP 1500 times or 50% Carbendazim WP 500 times before colonization. (4) Adding a small amount of 50% Skolin WP or 50% acetaminophen WP in 2,4-D or anti-dropping agents to prevent human transmission. (5) In the early stage of disease, 800 to 1600 times of benazepam, 50% of Suo Keling wettable powder 1500 times, or 65% of Benylurea WP 800 to 900 times, once every 7 days or consecutively 2 or 3 times, pay attention to alternate or alternate medication.
