Eggplant verticillium wilt is a common disease in the eggplant production. It is popularly known as “half madnessâ€. Once it is affected, the production is reduced by 20% to 30%, and serious to 50% or more. Since 2007, with the warming of the eggplant market, vegetable growers have a higher enthusiasm for planting. In the old vegetable growing regions, diseases of the eggplant vegetables have been severely plucked for many years, and the effects of traditional chemical control methods are not prominent. Below, introduce several kinds of prevention and treatment tips that are easy for farmers to use.
First, the high temperature drowsy greenhouse eggplant production in a closed microclimate environment, many years of heavy cropping, bacteria accumulation, a large number of chemical fertilizer put into use, soil compaction, salinization is serious, the beneficial bacteria in the soil is not conducive to survival, harmful A large number of bacteria accumulated, using high temperature stuffy shed is an effective method of physical control. Specific operating techniques are as follows: Select summer and July and August sunny high-temperature weather, spread the earth on the surface evenly fertilizer, urea, smashed crop straw, straw rot agent, deep pour, then poured a water, and then covered with old film Keep the surface temperature above 40°C for one week. Tests have shown that most of the harmful bacteria can be killed through high temperatures of 40°C. Using this method can greatly reduce the residual amount of harmful bacteria and reduce the chance of plant infection. The disease will naturally be significantly reduced. Depending on this method, less investment, labor-saving and labor-saving, and strong operability.
Second, grafting According to the type of planted eggplant mouth, select the appropriate variety. The method of grafting is an effective technique to increase the resistance of eggplant plants and reduce the occurrence of diseases. Plants that are tall and robust and grow strong can be used as rootstocks, and wild eggplant can also be used as rootstock.
Third, the drug irrigation root selection of Bacillus subtilis 250 grams of 250 pounds of water, diluted to 500 times the liquid, in the eggplant colonization irrigated root, the amount of 100 ml per plant. It can greatly enhance the ability of eggplant plants to resist harmful germs, protect the root system from pathogenic bacteria, and reduce the occurrence of Verticillium wilt. Wait until the eggplant enters the "blinking eye" period and then pour medicine again.
