The root rot disease is a brown rot of the diseased root surface, causing the xylem to be exposed. The leaves are wilting during the day, and it can be restored in the morning and evening. After repeated days, the leaves turn yellow and dry, and the whole plant dies. In the prevention and control, 50% carbendazim WP 500 times liquid can be used to kill 20001000 times liquid + Yunda 1201500 times liquid, 0.2-0.3 kg per plant, watering once every 7-10 days, continuous watering 3-4 Times.
Sclerotinia sclerotiorum can occur in the stems, leaves and fruits of plants. The symptoms are from the base of the main stem or the side branches 5-10 cm. The light brown water-immersed lesions are sunken, and then become grayish white and the temperature is long. White flocculent hyphae, the cortex rots. The surface of the stem and the center of the stem are black sclerotia. After drying, the hollow skin is easily broken, and the fibers are exposed to hemp to cause the plants to die. The fruit is damaged, sag, brown rot, and grows white mycelium, and then forms sclerotia. Formulation medication is ash, 700 times liquid + Yunda 1201500 times liquid spray, 7 days spray once, continuous spraying 3-4 times; or 50% speed Keling WP 1500 times liquid + Yunda 1201500 times liquid spray, Spray once a day for 7 times and spray 3-4 times continuously. At the same time, it should be noted that the seriously ill strain must be removed and taken to the outside for destruction.
The plague disease of cotton plague is harmful to fruits, stems, leaves, flowers and other parts. The specific symptoms are that the fruit is damaged, and the fruit on the ground is firstly affected. The lesions are round, concave, dark brown and rot, and white hyphae grow when the temperature is large. The stem is damaged, water-soaked, and overflows. When the temperature is high, white mold grows, and the upper branches and leaves are wilted. The leaf surface is damaged, forming a water-soaked brown lesion with a more pronounced pattern. In the prevention and control, you can use Anke 20g +80% Dasheng 75g + Yunda 12030ml to water 45kg spray, 7-10 days spray once, continuous spraying 3-4 times; or use Xinluling 600-800 times liquid + Yunda 1201500 times liquid, or Best 600 times liquid + Yunda 1201500 times liquid spray, 7-10 days spray once, continuous spraying 3-4 times.
The early blight of early blight mainly harms the leaves. The symptoms are round spots, brown edges, grayish white in the middle, and concentric circles. When the temperature is high, the lesions grow gray-black mold, and the central part of the lesions is brittle when dry. For the prevention and treatment of early blight, you can use Anke 20g +80% Dasheng 75g + Yunda 12030ml to water 45kg spray, 7-10 days spray once, continuous spraying 3-4 times.
The symptoms of Fusarium wilt are that the leaves turn yellow from the bottom to the top, and are mostly expressed on the 1-2 layer branches. Sometimes the same leaf is yellow and half green, and the stem vascular bundle turns brown. 50% carbendazim WP 500 times solution + 20001000 times solution + Yunda 1201500 times solution can be used for root irrigation, 0.2 kg per plant, rooting once every 7-10 days, continuous rooting 3-4 times .
Helicoverpa armigera, tobacco budworm, and diamondback moth can be sprayed with 1500 times solution of Yifu (0.8% avidin) or 1500 times solution, sprayed once every 7-10 days, and used alternately.
The mites can be sprayed with 1000 times liquid or Aimelo 30,000 times liquid spray once every 5 days.
For the prevention and treatment of sassafras, it can be sprayed with 1500 times solution and sprayed once every 7 days.
