Currently, 511000 mu of wheat in Nanzhang County has entered the heading and flowering stage, which is also a critical period for the infection of Fusarium head blight. The county adheres to the prevention strategy of “prevention first, proactive attack”, fully implements the prevention and control measures of “proactive attack, see flowers and apply medicine”, organizes socialized service units, invests more than 120 unmanned plant protection machines, carries out unified prevention and control, and ensures wheat yield and quality safety.
Recently, at the wheat scab prevention and control site in Jiebeitou Village, Wu’an Town, ten unmanned plant protection machines were conducting wheat scab prevention and control operations. Agricultural technology experts provided on-site guidance and explained relevant knowledge on wheat scab prevention and control to major farmers.
To prevent and control wheat scab, efficient pesticides can be selected, such as cyanoxylate, fluconazole hydroxylamine, propionazole, imidazole, tebuconazole, and other chemical agents as well as their compound preparations. Additionally, biological agents such as Bacillus subtilis, Bacillus subtilis, and Jinggang Bacillus subtilis can be selected for prevention and control. “said Wei Zunlong, an agronomist at the County Agricultural Technology Promotion Center. According to prediction analysis, this year’s wheat scab will occur with a moderate severity, There is a major occurrence locally. Remind farmers to prepare pesticides in advance and seize the season to carry out prevention.
Wheat scab is currently the most important disease affecting wheat production. After being infected, it not only leads to a decrease in wheat yield, affects wheat quality and safety, but also causes poisoning to humans and livestock due to its excessive toxins.
The effective prevention window for wheat scab is short and has strong timeliness. The best period for preventing and controlling the occurrence of wheat scab is from full heading to early flowering. Agricultural experts remind that according to the current wheat growth progress forecast, the first application time is April 3-10, and the second application time is April 11-18.
It is reported that this year, Nanzhang County invested 3.3 million yuan in centralized procurement of wheat spraying and three prevention agents, mainly aimed at preventing wheat scab. Four plant protection and flight prevention service organizations were selected through bidding, and more than 120 plant protection drones were invested to carry out unified prevention and control of 511000 acres of wheat in the county, laying a solid foundation for summer grain harvest.
