Which diseases and insect pests need to be controlled by eggplant in summer? Please introduce the need to control diseases and insect pests of eggplant in summer, there are the following for reference: first, eggplant pest control 1. Red spider: agricultural control should always keep the soil moist, avoid excessive drought, remove weeds and litter in time, and reduce the source of insects. The chemical control should strengthen the pest inspection, control in the spot film occurrence stage, choose 73% propargite EC 1200 times liquid, 40% dimethoate EC 1000 times liquid and so on spray treatment. two。 Aphids: the prevention and control methods should be used as early as possible, and it should be controlled at the stage of spot film occurrence. Agricultural control cleans up the leaves of residual plants in the field and removes weeds in time after vegetable harvest. The medicament control can choose 2.5% deltamethrin EC 2000,3000 times liquid, 50% aldicarb 2000 times solution, 20% chlorpromazine 2500 times solution and so on. 3. White whitefly: the control method can be added anti-insect net, covering silver-gray plastic film and yellow board. Whitefly has a negative tendency to silver gray, so silver gray plastic film can effectively avoid whitefly. White whitefly has already occurred in the shed, and the yellow board trapping can be set up by using the tendency of whitefly to yellow. For chemical control, green vegetable treasure plus lice scale ning can be used to spray 15 kg of water. In addition, plant growth conditioners such as Fengshou No. 1 and Yunda 120 can be sprayed to alleviate the adverse effects of insect pests on functional leaves. 4. Mites: the mites can be sprayed with 36% Ke mite fly EC 1000 × 1500 times, 5% carbazol EC 2000 times, 1.5% Abuddin EC 3000 times and so on. 5. Liriomyza huidobrensis: when there are 3 larvae on the leaves, before the 2nd instar of the larvae (the insect path is very small), after the dew dries at 8: 11, when the larvae begin to move to the leaf surface or when the larvae mostly come out of the insect path, start spraying 1500 times of 25% spotted net EC or 5% Yitaibao EC 2000 times. The effect is good when the control time is from 8 to 12:00 of the adult Eclosion peak. 2. Prevention and control of eggplant diseases. Cotton blight: cotton blight harms fruits, stems, leaves, flowers and other parts. The harmful symptoms are the first disease of the fruit near the ground, the disease spot is round and sunken, becomes dark brown and rotten, and white hyphae grow when the temperature is high. The stem is damaged, immersed in water, constricted, mildew grows when the temperature is high, and the upper branches and leaves wilt. The leaf surface is damaged, forming a water-immersed brown disease spot with obvious wheel pattern. Chemical control, you can use Anke 20 grams + 80% Dasheng 75 grams + Yunda 12030 ml to spray 45 kg of water, spray once every 7 days, spray 3 times 4 times in a row, do not ignore the base of the stem when spraying. two。 Verticillium wilt: eggplant Verticillium wilt, commonly known as "half yellow, half crazy", begins to show symptoms after fruit setting, and often develops from the bottom up or from one side to the whole plant. The symptoms are as follows: in the initial stage of the leaf, the veins yellowed and browned gradually, the edge withered or the whole leaf withered and yellow; the diseased leaves of the plant developed from the bottom up, wilted at noon in the early stage, recovered sooner or later, the leaves fell off in the later stage, and the whole plant died; the roots and stems were cut longitudinally, and the vascular bundles turned brown or black. In the early stage of the disease, the roots were irrigated with 500 times of 50% carbendazim wettable powder or 50% methyl topiramate wettable powder, about 0.25 kg of each plant, once every 7-10 days, and continuously for 2-3 times. 3. Powdery mildew: in order to prevent plant premature senescence in the later stage of full fruit, timely topdressing can reduce the disease; pay attention to reasonable irrigation and timely drainage after rain; strengthen ploughing and soil cultivation to promote plant root growth; timely removal of lower plant diseases and old leaves, not only reduce the source of bacteria, but also conducive to ventilation and light transmission. Spray 15% triadimefon wettable powder 1000 times or 40% Foxing EC 4000 times or 40% polysulfide suspension 500 times 600 times at the initial stage of the disease. 4. Virus disease: drug control can use 1.5% Zhishiling emulsion 1000 times or 20% virus A wettable powder 500x solution, sprayed every 7 to 10 days, 2 times 3 times in a row.
