How to prevent diseases in rainy weather for a long time after eggplant planting?
Strengthen management and choose fertile soil with high terrain and good drainage to plant eggplant. Ridge planting, when the rainy season comes, clean up the ridges and ditches, drain water in time after the rain, and lightly water well water to prevent the harm of hot rain. Apply base fertilizer, topdressing in time, increase phosphorus and potassium fertilizer, and avoid partial application of nitrogen fertilizer. The symptoms of eggplant brown stripe disease endangering eggplant fruit are: brown round concave spots with many small black spots arranged in a ring shape, and the diseased spots continue to expand to reach the whole fruit. In the late stage of soft rot, the diseased fruit falls to the ground or remains on the branches, showing dry rot and stiff fruit. Spraying fungicides every 7~ 10 days, commonly used are iprodione, ethephon, thiram, etc. At the same time, according to plant growth, foliar fertilizer can be sprayed to enhance plant stress resistance, improve low temperature tolerance and improve fruit quality. When applying pesticides to prevent diseases, it is necessary to inject eggplant cotton wilt: when cotton wilt occurs, eggplant leaves will produce diseased spots and grow white mold. In particular, the fruit suffered the most, and began to appear waterlogged circular spots with a slight depression. The pulp of diseased eggplant is dark brown, rotten and white.
Minimize the humidity. Most diseases are prone to occur in high humidity. In rainy season, the drainage ditch should be dug in advance to ensure that there is no water in the ground. If the soil is too wet, we can sprinkle plant ash on it. The surplus that plant ash can't absorb mostly exists in the form of rotten water, which has a bad smell, but the fruit has no hair, and the fruit exists in the form of mud. In severe cases, the fruit will fall off the eggplant, commonly known as "egg drop". This is the bacterial soft rot of eggplant, which is a common disease on eggplant.
