1. Sowing autumn seedling stage: prevention and control of total erosion disease, smut, sheath blight, stem base rot, root rot and other soil-borne and seed-borne diseases and underground pests such as needleworm and grub, as well as aphids, rust, etc., seeds can be coated or dressed, such as tebuconazole, difenoconazole, fludioxonil, siliothiazine, thiamethoxam, imidacloprid, phoxanthione, etc. 2. Rejuvenation jointing stage: focus on the prevention and control of sheath blight, stripe rust and other diseases and insects, taking into account powdery mildew, aphids, wheat spiders, stem base rot, etc. Use biological pesticides such as Jinggangmycin, polyantimycin, Trichoderma, matrine, and ear mold to control sheath blight and aphids. Spray with tebuconazole, propiconazole, fluconazole, thiofuramide, etc. 
Add ** notes, no more than 140 words (optional) 3 Heading and flowering stage: focus on the prevention and control of scab, sucking worms, taking into account powdery mildew, stripe rust, etc. Choose cyanoxystrobin, tebuconazole, perchlorine, etc. 4. Filling and maturity stage: focus on the control of wheat ear aphid, taking into account rust, powdery mildew and armyworm. Choose fluconazole, thiamethoxam and other high-efficiency, low-toxicity and safe fungicides and insecticides, and mix them with growth regulators, foliar fertilizers and other scientific mixtures to prevent diseases and insects, prevent premature aging, prevent dry and hot air, and have multiple effects in one spray. Wheat yield increase program - Watson full harvest This combination is a set of insecticide, disease prevention, nutrition, yield increase in one of the high-efficiency wheat spray three prevention**, in order to prevent disease treatment, insecticide and insect control, regulate growth, nutrition and yield for the purpose. It is formulated according to the law of fertilizer demand for growth and development of wheat and the characteristics of the occurrence of diseases and pests. It can not only effectively control wheat diseases and pests, but also regulate the growth of wheat, supplement wheat nutrition, promote leaf and stem thickness, and enhance wheat's ability to resist natural disasters such as dry and hot winds and droughts. The grain is fuller and the 1000-grain weight increases, so as to achieve the purpose of increasing yield and harvest. 
Add ** note, no more than 140 words (optional) Gibberella: For high-susceptible varieties, if the weather forecast wheat flowering period has more than 2 days of rainy weather, condensation or foggy weather, the first application time should be appropriately advanced to the full heading stage, and spraying 1 2 times after 5 7 days after the first prevention and control to ensure the control effect. In the middle and lower reaches of the Yangtze River, Jianghuai and other wheat areas where the pathogen has developed resistance to carbendazim, the use of carbendazim should be stopped, and single agents such as cyanostrobin, tebuconazole, prothioconazole, prochloraz, formadi, thiophanate-methyl, oxime tebuconazole, imicopper fluconazole, Bacillus subtilis, and compound preparations such as propaazole, tebuconazole, Jinggang and Wax Bacillus were selected. Stripe rust: The prevention and control agents can be used oxime tebuconozole, ** ketone, enaconazole, tebuconazole, fluconazole, hexaconazole, propiconazole, etherstrobin, pyraclostrobin, oxime tebuconazole, powderazole, pyrimidine nucleoside antibiotics, etc. Powdery mildew: the commonly used agents for diseases are ** ketones, enazole, mycloconazole, propiconazole, fluconazole, tebuconazole, prochloraz, etheroxystrobin, dimemetrichlor, etc.;In severe cases, it should be sprayed once every 7 to 10 days. Sheath blight: From wheat rejuvenation to the early stage of jointing, thiofuramide, tebuconazole, propiconazole, Jinggangmycin, polyantimycin, Trichoderma, Jinggang wax bacillus and other sprays can be used for prevention and control. Stem base rot and root rot: use tebuconazole, fludioxonil, cyanostrobin and other agents for seed dressing or coating;At the jointing stage of stem base rot, tebuconazole and prothioconazole were selected to spray and control the stem base. Foliar spraying of propiconazole and tebuconazole in the early stage of flowering to prevent and control root rot. 
Add ** note, no more than 140 words (optional) Aphids: Flufenthrin, pymetrozine, acetamiprid, imidacloprid, anti-aphid, matrine, ear mold and other agents can be used for spray control. Plasma sucking insects: use phosphine, chlorpyrifos, cyhalothrin, chlorofluoro-imidacloprid and other pesticides for spray control. The recurrent area is re-administered once every 3 days to ensure the prevention and control effect. Wheat spider: In the jointing stage of rejuvenation, avermectin, bifenthrin, mala phosphine, biphenyl **phosphorus and other agents can be used for spray control. Insecticides: imidacloprid, acetamiprid, pymetrozine, thiamethoxam, phosphos, deltamethrin, cyhalothrin, cypermethrin, fenvalerate, anti-aphid, avermectin, matrin, etc. Among them, imidacloprid and acetamiprid should not be used alone. Fungicides: **Ketones, enazole, tebuconazole, hexaconazole, propiconazole, difenoconazole, prochlorazole, fluconazole, thiofuramide, etherstrobin, pyraclostrobin, carbendazim, thiophanate-methyl, cyanostrobin, propathione-tebuconazole, prothioconazole, Bacillus cereus, Jinggangmycin, etc. Foliar fertilizers and plant growth regulators: potassium dihydrogen phosphate, humic acid or amino acid foliar fertilizers, brassinolides, amino-oligosaccharides, etc.
