Scabs, smut, total eclipse, root rot and other diseases on wheat are mainly controlled by seed dressing before sowing. The applicable drugs are tebuconazole, difenoconazole, chlorfenapyr and the like. . Generally, 3 to 4 grams of tebuconazole pure drug per 100 kilograms of wheat, or 6 to 9 grams of difenoconazole pure drug, or 2.5 to 5 grams of pure albino nitrile. It is recommended to use a professional suspension for seed dressing. Seed coating products. In areas where total eclipse is severe, silicillin can be used for seed dressing, which is highly effective against wheat. Silicomycin has poor control effect on smut and root rot. To treat these diseases, it is possible to add tebuconazole or difenoconazole. Currently, wheat is generally in the critical period before and after jointing. In recent rainy days, the soil moisture in the field is generally large, and the sheath blight is easy to re-emerge after the temperature rises. Pay attention to strengthening prevention and treatment. Thioflavamide, tebuconazole, hexaconazole, diniconazole, triazolol, epoxiconazole, propiconazole, benzoylpropanazole, sputum, tebuconazole, etc. The highly effective drug has a long-lasting effect. In the prevention and control of wheat sheath blight, in addition to the selection of the drug type and the amount of foot medicine, it is very important to use the amount of water. It is necessary to increase the amount of water to spray the powder and send the drug to the susceptible part of the wheat base to improve the control effect. When applying dew in the morning, it is beneficial to spread the liquid to the base of the wheat plant and improve the control effect. Before and after wheat jointing, the use of azoles such as tebuconazole to control sheath blight can reduce the prevention and control pressure of powdery mildew in later stage. Scab is one of the diseases that have the greatest impact on yield and quality in wheat production. The best control period for wheat scab is the initial flowering period (5% to 10% of the flowering rate), and the principle of “seeing flowers and playing†can be mastered in production. When wheat begins to bloom in the field, it begins to control the drug. Do not delay the use of medicines. When the wheat is in the rainy season, it should be applied in advance before the rain or in the rain. According to the weather conditions, the occurrence of pests and diseases, and the size of the planting, etc., the application time should be appropriately adjusted. The first application time can be advanced to the early stage of wheat heading. Wheat heading and flowering period is cloudy or rainy, or the variety is susceptible to disease. It is controlled once every 5 to 7 days after the first application. Cyanolide single agent (Jingshou) and its compounding agent with tebuconazole and hexaconazole, Jinxing 48% cyanide· tebuconazole suspension, solid 20% cyanide·hexazole alcohol suspension, A compound of tebuconazole with prochloraz and thiazolone, butyrazole, prochloraz, and ethiazole, which is a highly effective drug for controlling wheat scab, suitable for use in sufficient amount. Good control against wheat scab. In recent years, wheat powdery mildew has become heavier. Before and after wheat jointing, triazole drugs such as tebuconazole and its mixed agents with ether fungus and azoxystrobin have been used to control wheat sheath blight, and to control powdery mildew in later stages. It also has a good effect, and it is decided whether to apply the drug again or later depending on the occurrence of powdery mildew. The main influencing factors of wheat powdery mildew are climate, variety, fertilization level, sowing date, etc. The most critical factor is climate. From mid-March to late April, the temperature is high and the years of process rainfall are often onset. Heavier. The use of medicine to control wheat powdery mildew should be early and should not be late, it is advisable to use the medicine in the early stage of the disease, and the control effect of the drug should be reduced. Wheat powdery mildew usually occurs earlier than scab, and when powdery mildew is not heavy before heading, it can be treated with both drugs when it is used to control scab. When it is serious, it cannot be treated when it is used to prevent and cure scab. Triazole drugs such as tebuconazole, hexaconazole, diniconazole, triazol, epoxiconazole, propiconazole, and benzepazole have good preventive effects against wheat powdery mildew, and the therapeutic effect is not Stable, it can be mixed with ether fungus ester and azoxystrobin when it is used. If the condition of wheat powdery mildew is rapidly increased due to missed prevention or treatment, or improper use of drugs such as ether oxystrobin, azoxystrobin and its combination with triazole drugs, there is still obvious eradication and treatment. The effect is controlled once every 10 days depending on the disease control effect. 45 Degree Elbow,45 Degree Garden Hose Elbow,45 Degree Exhaust Elbow,Custom 45 Degree Elbow Jinan Huancheng Heating Equipment Manufacturing Co., Ltd. , https://www.globalstove.com
