How to Prevent Brown Vegetation in Eggplant

Eggplant brown leaf disease is a great harm to eggplant, and its leaves, stems and fruits can be affected. The pathogenic fungi are hyphae, conidiospores on the surface of the surface of the diseased tissue, or hyphae lurking in the seed coat, or conidia attached to the seeds for winter. In the following year, the seeds of the seedlings caused the onset of seedlings, and soil carriers caused ulcers in the base of the stems. They produce conidia and become the source of infection in the leaves, stems, and fruits of the field.
Germ development and formation of conidia optimum temperature of 28-30 °C, the formation of a suitable temperature for the spore device is 30 °C, conidial germination temperature is 28 °C, suitable for the occurrence of the disease incubation period of 3-5 days, Adult plants 7-10 days. The temperature in the field is 28-30°C, and the relative humidity is higher than 80% for a long time, or continuous rain, and the disease is prevalent. In addition, it is related to cultivation management and varieties. Generally for many years continuous cropping, or seeding seedbed too dense, thin seedlings, planting plots low-lying, heavy soil, poor drainage, heavy nitrogen fertilizer incidence. There is a certain difference in disease resistance among varieties, long eggplants such as white-skinned eggplant and green-skinned eggplant are often more resistant to disease than purple-skinned and black-skinned eggplants.
Prevention and cure of eggplant brown leaf disease should focus on rotation and selection of disease-free seeds, supplemented by pharmaceutical protection. The second is the implementation of more than three years of rotation, the selection of disease-free seeds. The first thing to do is pick seeds from disease-free eggplant. Before sowing, the seeds were immersed in warm water at 55°C for 15 minutes, or immersed in warm water at 50°C for 30 minutes. The seeds were soaked in cold water and allowed to cool and then sowed. The third is seed bed disinfection. Seed beds need to be replaced with new soil every year. When sowing, use 50% carbendazim 10g per square meter, or 50% thiram 6-8g mixed soil 20kg made of medicinal soil, take 1/3 sprinkled on the surface, and then sowing, after sowing The rest of the medicinal soil covers the top of the seed. The fourth is to use resistant varieties. The fifth is to strengthen the cultivation and management, nurture strong seedlings, apply sufficient basal fertilizer, and promote early growth. Advance the harvesting period of eggplant before the epidemic season can effectively control the disease. Sixth, chemical control. In the result period of eggplant, in the rainy season, 75% chlorothalonil wettable powder 600 times, or 70% mancozeb dry powder 500 times can be sprayed.
