Eggplant verticillium wilt and wilt disease are one of the major diseases of eggplant. With the expansion of cultivated area, it has aggravated the incidence in recent years. Eggplant Verticillium wilt not only harms Solanaceae vegetables, but also harms many kinds of vegetables such as Cucurbitaceae and Cruciferae.
1, the symptoms of eggplant Verticillium wilt disease incidence is small, usually soon after the onset of eggplant disease, if the case of low-temperature colonization, the incidence of early and heavy, but most of the incidence after fruiting. The performance of diseased plants mostly grows from bottom to top or from one side to the whole plant. At the beginning, the leaves turn yellow between the leaf margins and veins, and then develop to half of the leaves or the whole leaf turns yellow. The early disease leaves are wilting at sunny high temperatures and can be recovered sooner or later. The late-stage disease leaves turn yellow from yellow and eventually causes wilting. As a result, the leaves of the whole plant become brown and wilted, and even the stalks are only stripped. By dividing the roots, stem branches and petioles, the vascular bundles became brown, but there was no watery turbid fluid that was different from bacterial wilt. Slurry cuttings of mature fruit, can also be seen dark brown vascular bundles.
Eggplant wilt often occurs in the adult plant. When the temperature reaches 25-28°C and the soil is wet, it is extremely beneficial to the disease. The leaves of the diseased plants gradually turn yellow and withered from the bottom upwards, and the symptoms are often expressed on the branches of the first and second layers. Sometimes only one half of the same leaves turn yellow, and the other half is normal as usual. When the condition is serious, the whole leaf is yellow. Cross-cut stems, diseased vascular brown.
2, control measures selected disease-resistant varieties. Common disease-resistant varieties include Black Marshal No.1, Green Ham Eggplant, Eggplant King, Long Soybean No. 1, Liao Kee No. 1, Feng Yan No. 1 and so on.
Implement a rational rotation. More than 3 years of rotation with non-solanum crops, such as onions, garlic, and rice.
Cultivate disease-free strong seedlings. The seedbed shall be replaced with new soil or the soil shall be treated with Greenhenge No. 1. The disease-free seeds shall be used or the seeds shall be disinfected. For example, 0.50-1g of Greenhenge No. 1 and 4g of Greenhenge No. 2 shall be mixed and seeded after each kilogram of seeds.
Do a good job in cultivation management. Fine and timely planting eggplant seedlings, early control of watering, strengthen the cultivator. Sorghum mulching film to improve ground temperature and soil permeability. Increase the use of decomposed organic fertilizer to maintain robust plant growth and increase disease resistance. After harvesting the phytophagous, start topdressing or spray the green hentai Tempo to 15-20 kg of water per 10 ml.
Chemical control. At the beginning of the disease, timely irrigate the roots with 3000-times of Green Hunter No. 1 and 100 ml per plant. It was sprayed with 600-800 times of green hens, sprayed every 7-10 days, and sprayed 2-3 times.
