How to prevent eggplant gray mold

In the process of growing eggplants in greenhouses, due to the low temperature and high humidity in the greenhouses, the release of air is not timely, resulting in the production of semi-mycotic fungus and botrytis. The pathogens directly invade the tomato wounds and open buds and incur in the diseased areas. A large number of conidia, leading to rapid pathogens, causing the tomato fruit to become soft rot, dehydration and shrinkage into a stiff fruit, when the damp disease has a layer of mildew, severe when the branches can die, causing a threat to the greenhouse eggplant Big gray mold! ! !
Control methods: 1, to strengthen the cultivation and management. Before and after the onset of growth, proper control of watering, greenhouse ventilation, reduce greenhouse humidity, reduce roof and leaf surface condensation and leaf edge spit water, timely removal of diseased leaves, diseased flowers, diseased fruit and yellow leaves, to maintain the shed The room is clean and airy.
2. In the period of flowering and fruit setting, use [black and light Baole Capsule] to spray and preserve fruits (reducing the production of gray mold). Because the mold of Botrytis cinerea is easy to invade into the petals of open and defeated, and then it is quickly applied. If treated with 24-D and anti-dropping ingredients (tomato spirit), the flowers will generally fall off within 2-3 days (prone to produce Botrytis cinerea). If you use [Black and Bright Baolei Capsule] to do flowering and fruit protection, you can keep the petals fresh for more than 7-10 days (it can reduce the invasion of Botrytis cinerea), and the fruit set rate can reach more than 90% in rainy days (in the shed ), And the fruit setting rate is more than 50% higher than 24-D, anti-dropping element (tomato spirit), [Black and Liang Bao Lei capsule] produced by Hebei Hongjiao Hongwei Agricultural Science and Technology Development Co., Ltd., telephone. Mobile phone 3, drug control, early onset can be used 50% Suo Keling WP 2000 times or 50% acetaminophen WP 1000-1500 times or 75% chlorothalonil WP 600 times spray.
4, smoke agent treatment. In the early stage of disease, in order not to increase the humidity in the greenhouse, chlorothalonil smoke agents may be used, each time using 250 grams per acre and smoking at intervals of 6-7 days to control gray mold.
