Sheath blight is one of the most influential diseases on wheat yield. Last year, many wheat fields failed to prevent and control in the early stage, resulting in a white spike at the maturity stage of wheat, which seriously affected the yield. This year, the cultivation area of ​​high-susceptibility varieties is large, and the prevention and control of sheath blight is particularly important. According to recent surveys, the field disease incidence rate is 37.3%, and the diseased plant rate is 0.98%, which is equivalent to the previous two years. As the temperature rises, the disease of wheat sheath blight will rise rapidly. It is expected that the stalk will be invaded in mid-March, and the occurrence will be moderately heavy. The control of sheath blight is suitable in the middle of March. For each acre, 10% oxazolol emulsifiable concentrate 40 ml or 35% Jinggang oxazolol microemulsion 100 ml can be used, and 100 kg of water is sprayed. Practice has shown that oxazolol and its compounding agent have better control effect on sheath blight, and at the same time have the effect of inhibiting internode elongation and preventing late lodging. Affected by low temperature and drought, the weeding in this year's wheat field is small and the effect is poor. Although the amount of weeds is low, the weed density and the number of approved plots are significantly higher than normal. To control grass weeds in wheat fields, you can use wheat 15% acetylene ester wettable powder 40g per mu, or 6.9% quinoacillin water emulsion 100-120ml; demonstration application of 5% azole 100 g of porphyrin acetylacetoate emulsifiable concentrate or 15 g of 7.5 mg of sulfamethoxazole water-dispersible granules. For the control of malignant weeds such as bluegrass, buckwheat, and Japanese maiden, disulfonate-iodronone can be used. To prevent swine fever and phlegm, it can be used for acreage of 20% chlorofluthoxyacetic acid emulsifiable concentrate and 150 ml of 13% 2 methyl 4 chlorohydrin. To prevent pig mites and leeks, use Pentium 36% oxalic acid per ton? Benzsulfuron-methyl WP 7.5 ~ 10 grams; control pig mites, leeks, luxuriant, can use 55% benzoxazole per acre? 2 methyl sodium wettable powder 50 ~ 75 grams. Pentium 36% oxacillin? Benzsulfuron-methyl WP can not be mixed with other drugs, such as the occurrence of wheat seedling burns, yellowing and other phenomena, strengthen the field tube wheat seedlings can fully restore normal growth.
