Agricultural control
Deep plowing. At present, most areas in the Huang-Huai-Hai region have continuously promoted straw returning and rotary tilling techniques for more than 10 years. Rotary tillage technology has little impact on the damage of winter wheat fields, and the return of straw to the field has led to an increase in false-neutrality of land, which is beneficial to wheat damage. The winter is over. Therefore, we suggest that in areas with favorable conditions, two-year rotation ploughing should be promoted to deepen the intensive cultivation technology one year to create a site that is not conducive to overwintering of wheat pods, which can effectively eliminate over summer eggs and adults, and reduce the source of insects.
Strengthen field management. When cultivating land, it is necessary to apply fertilizers to enhance the wheat's own resistance to insects. Areas with irrigation conditions should adhere to winter irrigation and kill the source of overwintering insects.
Chemical control
The pests of wheat are small in size, occur early and reproduce quickly, so pest investigations should be strengthened. The survey was conducted once every 5 days after turning green wheat, when wheat ridges had a single row of 33 cm with 200 insects, and most of the leaves were covered with white spots, the application of pesticides was prevented. The control agent can use avermectin pesticides (there are contact and stomach poisoning, but no systemic effect), 20% Poria (with contact effect, no systemic effect) wettable powder (1000-1500 times liquid) , 15% Dai Ling EC (2000-3000 times), 40% Dimethoate (with contact, stomach poisoning, and systemic absorption) or 50% malathion (touch, stomach poison and certain fumigation, no Systemic action) (2000 times liquid) Spray on water. Spraying requires uniform, uniform, uniform speed.
