In 2017, the range and severity of armyworm in Daquanyuan Township were severe, posing a threat to agricultural production. The township actively organized agricultural technicians to implement prevention and control measures as soon as possible to curb the risk of armyworm outbreaks and achieve a “harvest of insect populationâ€. The main chemical control measures are as follows:
1. Sticky insects in the area should adhere to the principle of “treat early, treat small, and treat the disease†and seize the critical period before the larvae’s third-infant binge-eating hazard, and concentrate on contingency prevention and control to control outbreaks and curb hazards. Chemical control agents use pyrethroids such as 25 g/l deltamethrin or 5% lambda-cyhalothrin for water spray control.
2. The spraying time should be before 9:00 am or after 5:00 pm in sunny days. In case of rainy days, it is necessary to spray in a timely manner, requiring uniform and thoughtful spraying, and weeds must be sprayed in field ponds. In case of high density of armyworm, Properly increase the dose.
3, to ensure the safety of medication. Strengthen pesticide quality and price supervision to ensure that farmers use good quality and cheap pesticides and medical equipment. At present, during the hot season, vigorously promote and guide farmers to use pesticides safely to ensure the safety of the environment, production, people, and livestock.
