Planting eggplant in protected areas is a common phenomenon caused by disease hazards. Once it occurs, it will affect the yield and affect the quality. For this reason, disease control must be performed on the basis of comprehensive prevention and treatment in order to effectively prevent rotten fruit.
First, the main diseases caused by rotten fruit are the following: 1. Botrytis cinerea: first produce brownish water dip spot from around the fruit dike, dark brown after expansion, the surface produces gray moldy material, the fruit becomes black and rot inside . 2. Bacillus diseases: water-immersed garden-shaped lesions, after the expansion was yellow-brown, wet Department of disease-prone white cotton-like mycelium, the fruit turns black rot. 3. Brown streaks: brown garden-shaped pits with spots on the black brown. When the lesions expand, there are ring patterns, and later the diseased fruit rots or becomes a fruit. 4. Anthrax: water-immersed garden-shaped or irregular lesions, after the expansion of concentric ring pattern, a lot of small black spots on the close dense, surrounded by a wet-like color-changing circle, the fruit turns black and rot. 5. Sclerotinia: The diseased part is light gray-brown and immersed in spots. It appears dark brown after expansion. When wet, the surface produces white mould and produces black granular sclerotia.
Second, control 1. Agricultural control: 1 the implementation of crop rotation, should avoid continuous planting with solanaceae and melon vegetables, can be used in conjunction with cruciferous and bean vegetables. 2 to strengthen the cultivation and management, it is appropriate to use sorghum deep trench cultivation, reduce field moisture, timely pruning and removal of leaves and other diseases and pests, strengthen ventilation and light, so that is conducive to plant growth and development, unfavorable to the occurrence of germs. 3 Do a good job of seed disinfection and ground sterilization, the seed can be sowed before the new high-fat membrane 600 times liquid soaking. 2. Chemical control: The main prevention is to use root canal, spray sterilization bactericide. For the control of brown zebra disease and anthrax, the use of new high-fat membrane 600 times, or 70% mancozeb WP or anti-virus WP600 times, or 10% GW1500 times the world's high liquid and so on. Usually every 7 to 10 days, depending on the condition of continuous use of 3 to 4 times, the drug can be used interchangeably.
