First, the major pests and diseases of millet According to the survey of national millet pests and diseases in recent years, it has been clarified that there are 25 main diseases that damage China millet and 54 main pests. The occurrence of pests and diseases in different millet planting areas is quite different. Major diseases: rust, gluten, white disease, smut, virus disease, nematode disease, brown strip disease, sheath blight and so on. The main pests: underground pests (goldworms, cockroaches, cockroaches), millet negative slime insects, millet scorpion flea beetles, millet-spotted leafhoppers, leafhoppers, armyworms, corn borers, and millet flies. Second, comprehensive prevention and control technology 1. Before broadcast. (1) In Chungu district, straw and weeds are treated before winter, and field plots and surrounding weeds are treated before summer sowing to destroy pests' habitats and reduce the amount of insects in the following year. (2) Suitable sowing to ensure the soil moisture and promote the germination of grains. 2. Sowing period. (1) Selection of pest-resistant species. According to the local occurrence of pests and weeds, choose pest-resistant varieties. The main disease-resistant varieties are: Chuangchuang 1, Haogu 15, Chaogu 15, Baogu 18, Zhenggu 10, Yugu 3, Jigu 11, Lugu 5, Jinu 21, Jingu 30 and other varieties. (2) Seed treatment. 35% metalaxyl WP for prevention and treatment of white disease is seeded at 0.2% of seed weight. The control of sheath blight was performed with a 2.5% fludioxonil suspension at 0.1% of the seed amount. 80% carbendazim WP for smut control is seeded at a seed amount of 0.3%. To prevent and control nematode diseases, concurrent treatment of cockroaches, goldworms, cockroaches, and other underground pests, 40% methylisoprenofossil emulsion can be used to seed the seed 0.2%-0.3%, and boring for 4 hours. Prevention of white disease, nematode disease and underground pests, can first use 30% acephate EC seed dressing, boring for 4 hours, then add 35% metalaxyl wettable powder mixed seed dressing, to achieve a mix of more than prevention purposes. 3. Seedling period. One prevention before and after sparse seedlings. Can be used 20% imidacloprid wettable powder 1500 times mixed with 2% avermectin EC 3000 times spray. It can control the planthoppers, aphids, and red spiders. In addition, it can also treat pests such as millet fleas and millet worms. The seedling-free seedling variety field can be combined with the mixture of seedling agent and insecticide and bactericide to achieve the purpose of spraying and preventing. 4. Adult stage. Pay attention to early prevention, appropriate drug use, and more than one spray. The adult stage diseases are rust, gluten, white disease, brown strip disease, and sheath blight. Insect pests are mainly corn borer, armyworm, and mantle flies. (1) Rust. When the diseased leaf rate reached 1%-5%, the first spraying was performed with 15% triadimefon 600 times liquid, and the second spraying was performed as appropriate after 7-10 days. (2) gluten disease. When the leaves were first seen in the field, they were sprayed with 40% rice bran oil 1000-1500 times or 6% kasugamycin wettable powder 1000 times, and sprayed 1-2 times at intervals of 5-7 days. After heading, it is best to control once for the ear. (3) Sheath blight. When the diseased plant rate reaches 5%, 12.5% ​​of wolfberry WP can be used to prevent and cure once at the base of the millet stalks, and after 7-10 days, it can be supplemented once. (4) Brown strip disease. In the initial stage, use 72% of agricultural streptomycin 4000 times or 20% Thiosin Suspension 500 times for 2-3 times. (5) White onset. Remove field strains (especially "gun lances") and bring them out of the field to burn or bury them deeply. (6) Insects. Use a straw or sweet and sour liquid to seduce the adult. Or when the armyworm is under 3 years of age, use 90% trichlorfon crystals, 80% dichlorvos EC 800 times, or 20% fenvalerate EC 2500 times. (7) corn borer. Adult insects are killed by insecticidal lamps and sex attractants. Or in late August, adult eggs are sprayed with 2.5% deltamethrin EC and 40% dimethoate EC 1000 times before spawning to the stem of the instar larvae. And cure stickworm. (8) Millet flies. It can be sprayed on stems with 4.5% beta-cypermethrin 1000 times and 20% fenvalerate 2000 times. 5. Harvest period. (1) White incidence. Pull out the diseased plant and take it out of the field and bury or burn it. (2) Nematode and smut. Remove sick ears and leave no seeds.
