Eggplant Verticillium wilt often begins to show symptoms after fruit set, developing from bottom to top or from one side to the whole plant. The leaves begin to yellow at the leaf margins and veins, and then develop to one and a half leaves and turn yellow. Later, the diseased leaves turned brown from yellow, and finally wilted and fell off. Fusarium wilt develop from the seedling stage to the harvest period of adult plants. The diseased plant leaves yellow and withered from the bottom up. Root rot mostly occurs after planting. During the initial onset, the leaves are wilted during the day and can be recovered sooner or later. After many days, the leaves turn yellow and dry. At the beginning of the onset of bacterial wilt, only one or a few leaves of individual branches became pale, showing partial wilting, then spreading to the whole plant and finally becoming brown. These are soil-borne diseases. Chemical control: Eggplant Verticillium wilt, Fusarium wilt, and root rot can be used in the early stage. Root rot 40% WP 800-1000 times or carbendazim 50% WP 500-800 times Irrigation, bacterial wilt Jia Daning or collateral ammonia or blue and dry net irrigation roots.
Eggplant Mushroom Disease occurs favorably in high temperature, high humidity, continuous cropping land, and low waterlogging land. It mainly damages fruits and causes a lot of rotten fruit. At the early stage of disease, the lesions are water-stained and round, and the rapid spread extends to the whole fruit. The lesions are brown or dark brown, gradually shrinking and becoming soft. When the humidity is high, the disease minister is full of hairy white hyphae, and finally the diseased fruit rots or becomes a stale fruit. Chemical control: At the beginning of the disease, 25% metalaxyl solution, 58% metalaxyl manganese zinc 500% solution, or Proplex 700 times fluid may be used. Spray once every 7 days for 3-4 consecutive times.
Brownie disease of eggplant is prone to occur under conditions of high temperature and high humidity. The onset of disease in the field begins with the bottom leaves, resulting in a pale, water-stained, small spot in the early stages, followed by a brown, round lesion. In the later period, it became an irregular large lesion with dark brown edges. The lesions continued to form one at a time. The perforation was perforated, and finally the leaves withered and died. The lesions of the fruit were round or oval, and the diseased part was slightly sunken and brown with concentric ring patterns. The diseased fruit is spongy inside. The lesions spread further up to the entire fruit, often causing fruit drop. Chemical control: 70% chlorothalonil 800 times solution or 701% mancozeb 500 times solution or 70% thiophanate-methyl solution 800 times solution is used in the early stage of disease. Spray once every 5-7 days for 3-4 consecutive times. Times.
Plastic Spot Welding Machine, mainly suitable for automotive sound insulation cotton, mask ear straps, plastic parts and other products that need spot welding, its principle is that the generator generates pressure, and the transducer produces the same frequency of alternating current, converted from piezoelectric ceramics into mechanical vibration, and mechanical vibration produces thermal friction. Friction melts the contact point between the two parts, allowing the part to bond quickly.
