How to control the main diseases and insect pests of sesame? Please give guidance on the main diseases and insect pests of sesame: 1. Sesame diamondback moth: when the plant has 2 larvae on average before the 3rd instar of the larva, it should be controlled by pesticide. Commonly used agents: 2.5% trichlorfon powder or 5% carbaryl powder sprayed 1.5-2.5kg per mu; 2000 times liquid spray of 90% crystal trichlorfon or 80% dichlorvos EC. two。 Ground tiger: ① sweet and sour solution traps and kills adults. Set up a sweet and sour basin in the field, with a depth of 3 cm and a diameter of about 25 cm. The proportion of sugar and vinegar in the basin is as follows: 1 part of liquor, 2 parts of water, 3 parts of sugar, 4 parts of vinegar, 5 grams of 90% crystal trichlorfon, which can trap and kill some adults. ② poison bait. 90% crystal trichlorfon 0.5 kg, 2.5-5 kg water mixed with chopped fresh vegetable leaves into poison bait, placed at a certain distance between crop rows in the evening to trap and kill larvae. ③ spray. Before the 3rd instar of the larvae, 2.5% deltamethrin EC or 20% butyl EC 1500-3000 times or 50% phoxim EC 1000 times were sprayed. 3. Aphids: when there are aphids in 10% of the plants, the average number of aphids per 100 plants in the seedling stage is about 150, and when the average number of aphids in the adult stage is 500-1000, the commonly used insecticides: 2.5% deltamethrin EC or 20% fenvalerate EC 8000 times spray. 4. Stem point blight, Fusarium wilt, vertical blight: for stem point blight, the plant can be irrigated with 600 times of 70% methyl thiophanate wettable powder solution of 200-250 ml per plant, or it can be sprayed with 150 Bordeaux solution or 0.5 degree stone sulfur mixture before and after topping of sesame. For Fusarium wilt, the diseased plant was irrigated with 50% carbendazim wettable powder or 70% methyl topiramate wettable powder 600-800 times, 250 ml per plant, once every 10 days, 2-3 times continuously. For Rhizoctonia solani, it can be sprayed with 20% methyl fumarate EC 800x or 50% dimethophos powder 800x-1000 times. 5. Epidemic disease: at the initial stage of the disease, it can be sprayed with 1purl 100 Bordeaux solution or 0.1% copper sulfate solution or 64% alum wettable powder 800 times or 58% metalaxyl manganese zinc wettable powder 800 times. 6. Bacterial wilt: acid soil, appropriate application of quicklime and plant ash to adjust the pH value of the soil. When the disease occurs sporadically, remove the diseased plant and disinfect the disease point with quicklime. Before the onset of the disease, 50%DT fungicide or 70%DTM wettable powder can be sprayed with 500x liquid, or 10% Shuangxiaoling water agent can be used to irrigate the plant, 250ml per plant, once every 7 days, 2-3 times in a row.
