Right now, the wheat market in the city of Shishi is at the heading stage. According to surveys conducted by the Plant Protection Station on counties (cities), the main diseases and pests of wheat are mainly wheat stubble, wheat midge, wheat scab, and wheat grass weeds. The plant protection station reminds The majority of growers are doing a good job in the prevention and control of diseases and pests in the mid and late stages of wheat production to ensure a bumper harvest of summer crops.
According to investigations, at present, the city's wheat aphids have an area of 1.883 million mu, with an average of 100 strains of 85 species, of which the highest amount is 332, which is close to the level of the same period of last year; the area of wheat midge insects is 193.80 million mu, among which the prevention and control indicators (worms) More than 2 heads/sample squared) covers an area of 975,500 mu.

When wheat meets continuous rain during heading and flowering, and the temperature is maintained above 15°C, the incidence of head blight will increase. According to the meteorological observatory, the weather in the next week will be mainly cloudy and showers, which will be conducive to the occurrence of head blight and spread. In the autumn of last year, the wheat field weeds in wheat fields in our city were all controlled again and again. For wheat fields with poor control effect, the agricultural experts at the Municipal Plant Protection Station reminded that the initial stage of grouting after wheat heading must be uprooted in a timely manner and taken out of the field to reduce the retransmission. .
Right now, with the increase in temperature, the mid- and late-stage diseases and pests of wheat in our city will enter the peak period. Various departments at all levels must effectively monitor the pests and diseases, provide timely feedback, and scientifically guide prevention and control. We must seize the current favorable timing, do a good job of propaganda, and timely eliminate the control of land that has reached the standard. Prevention and control should give full play to the role of this year's wheat pesticide pest control subsidies, do a good "one spray and three defenses," in ensuring the prevention and treatment at the same time, improve the prevention and control efficiency.
