How should herbicides be used after wheat emerges? Please provide guidance.
Summarize the experience of chemical weeding in wheat fields across different regions. Different chemical herbicides should be selected according to different wheat seedling conditions and wheat subsequent crops. The following herbicides can be selected:
Maiji quizalofop-p-ethyl, namely 15% quizalofop-p-ethyl wettable powder, mainly controls various grass weeds, has a broad weed-killing spectrum, strong permeability, and a relatively long application period for weed age. Weeds at the 2-8 leaf stage after wheat can all be controlled, but the control effect is best on weeds at the 2-4 leaf stage. Use 20-30 grams per mu, dilute with 30 kg of water and spray.
Chuning + Quechu, namely flucarbazone-sodium 70% water-dispersible granules plus quizalofop-p-ethyl 15% microemulsion. It mainly controls annual and perennial grass weeds, has good adaptability to both low temperature and rainfall, and is a newly formulated excellent post-emergence herbicide for wheat. When weeds are at the 2-4 leaf stage, use 2 bags of each of the two agents, dilute with 30 kg of water and spray. If 3 bags of each of the two agents are used and diluted with 45 kg of water for spraying, it can not only kill grass weeds at the 5-8 leaf stage, but also kill some broadleaf weeds.
9% Puma suspension concentrate or 10% Puma emulsifiable concentrate can prevent and control various monocotyledonous weeds. Use 40-80 ml of 6.9% Puma suspension concentrate per mu, or 30-50 ml of 10% Puma emulsifiable concentrate, dilute with 30 kg of water and spray. The suitable spraying time is the 3-5 leaf stage of wheat.
Baijia mixture can prevent and control various broadleaf weeds, especially difficult-to-control weeds such as Galium aparine and Persicaria maculosa. Use 10-12 ml of Banvel aqueous solution per mu, add 125-150 ml of 20% MCPA aqueous solution, dilute with 30 kg of water and spray. The spraying time is from the 3-leaf stage of wheat to before jointing. This mixture can only be applied when the subsequent crop is rice.
Be careful to choose windless or breezy weather for application to prevent phytotoxicity to surrounding crops.
