Changle, Linyi, Pingyin and other places to reflect the growth of sweet potato planters: the local re-planting of sweet potatoes, diseases, and more severe deafness, seek control measures. Jia Dengsan, a senior agronomist of the Changle County Agriculture Bureau, is a dangerous and devastating disease caused by the infestation of stem nematodes. It is common in China's sweet potato cultivation areas. The provinces of Henan, Anhui, and Anhui are the heaviest. With more and more people taking sweet potatoes as a health food, their prices have continued to rise, and the area under cultivation has expanded rapidly, bringing with it the problem of aggravation of diseases caused by the growth of sweet potato stem worms. The annual hazard of the disease: a rotten cellar during storage, rotten seedlings during the nursery period, dead seedlings, potato rot caused during the field. It invades the roots, vines, and seedlings of the sweet potato, resulting in poor root development, small size, deformity, cruelty, reduced quality, and reduced yield. Generally, the output is reduced by 20-30%, and the weight is more than 50%. The hazards of the disease: 1, rapid reproduction. A female lays 1-3 eggs at a time and one egg produces 100-200 eggs. It takes about 25 days to complete a generation. It can breed for more than 10 generations a year. A female can breed thousands of herds a year. 2, strong ability to survive. It is resistant to low temperature, resistant to dryness, and does not die at temperatures as low as -15°C. It starts to move at a temperature of 2°C, and is most suitable for activities at 20°C to 25°C. It is inhibited at 35°C, and it is inhibited in hot water at 48°C to 49°C for 10 minutes. Death reached 98%. It can safely overwinter in potato and soil. 3, a wide range of transmission. Diseased seed potatoes, seedlings, stems are the main route of transmission. The disease can also be transmitted by close proximity using diseases such as diseased soil, diseased fertilizer, running water, powdered slag, powdered water, and agricultural operations. Therefore, prevention and control work must be “mainly prevention-oriented, comprehensive prevention and controlâ€, and the ring must be fastened, and prevention and control must be done in order to eliminate its harm: 1, strengthen quarantine. The sweet potato stem nematode disease is a quarantine subject of plant diseases and pests in China, so that it is not necessary to adjust seeding from a diseased area with stem nematode disease and buy seedlings. Strictly quarantine the incoming and outgoing seedlings and prevent disease from being introduced into the disease-free zone. This is a key measure to prevent the disease-free zone. 2. The establishment of a disease-free seeding area and the cultivation of disease-free strong seedlings are the fundamental measures for preventing and treating the disease. To choose a land that has not been planted with sweet potatoes, unsun dried potatoes, or disease-free fertilizer for more than 3 years to be used as farmland. Leave the field to apply net fertilizer and pour water. Before the frost falls, choose the sunny harvest, choose the disease-free, no-damage potato chips, and enter the pit on the same day. When the potato seedlings were selected by water, they were soaked in hot water at 51°C-54°C for 10 minutes to kill the nematode on the surface of the potato shoots. And to do a seedling, spray a concentration of 0.5% phoxim liquid. Using high-cutting seedlings, cut the base of the seedlings 3-5 cm, remove the diseased part of the base, and soak the seedlings (leaves below) for 150 minutes with 150-200 times the 50% phoxim emulsion solution to ensure that the seedlings are not Sick. 3, at any time to remove diseased plant residues, and deep buried or incineration. Seize the spring potato seedlings, summer potato transplanting, harvest storage and other links, at any time to remove the diseased plant debris, concentrated deep or incineration, control the spread of disease sources. 4, the implementation of rotation for change. The diseased land will be replanted with cotton, sorghum, corn, millet, sesame and other crops for more than three years. The disease prevention effect is very good. According to the author's survey in Changle, Anqiu, Linyi, and other cities and counties, serious changes in cotton, corn and other crops after 3-5 years, the replanting sweet potatoes are mostly not disease, or the incidence is very light. The incidence of sick fields decreased from 31.3%-63% before rotation to 0.8%-6.3%. But can not be changed to planting onions, peanuts, potatoes and other crops. 5, selection of disease-resistant varieties. The selection of disease-resistant varieties is an economic and effective measure, and the use of virus-free seedlings has a good disease-prevention effect. The varieties of Beijing 553, Jishu 10, Jishu 18, Lushu 3, Yushu 13th, Sushu 8, Haoshu 3, Lushu 7 and other varieties with high disease resistance and high yield can be used. 6, Datian chemical control. When transplanting, use 50% phoxim 0.5-0.6 kg per acre, dilute 2,000 times, and pour 0.5 kg of liquids per hole. Or per acre with 5% stem line granules 1.5-2 kilograms, fine dry soil made of 30 kilograms of toxic soil, when transplanting every hole in the poisonous soil of about 10 grams, and then watering seedlings. According to Lu, Yu and other provincial experiments, the stem disease prevention effect can reach 84% -95.5%.
