What are the precautions for using herbicides in wheat fields?
What should be noted when using herbicides in wheat fields? How should it be done? Applying herbicides to wheat requires the following strict practices: Strictly select herbicide varieties. There are many types of herbicides, and each herbicide has a certain spectrum of weed control. Some herbicides have a very narrow weed control spectrum, such as barban, which can only control wild oats; MCPA controls shepherd's purse, purslane, and wild oats very well, but its effect on cleavers is very poor; 2,4-D is effective against broadleaf weeds such as amaranth, but ineffective against grass weeds. Farmers should choose the right herbicide according to the most common weed species in the wheat field in order to achieve the desired effect. To control broadleaf weeds, herbicides such as chucaojing, dicaojing, tribenuron-methyl, and baijia mixture can be selected for good control results; however, metsulfuron-methyl, chlorsulfuron, and maicaoer can only be used early in wheat fields under a rice-wheat rotation system. If crops such as cotton, corn, peanuts, or beans are planted after rice, serious phytotoxicity will occur, leading to frequent incidents of almost total crop failure.

How can phosphate fertilizer efficiency in wheat fields be improved? Practical methods shared
1. Apply after mixed composting and fermentation with organic fertilizer. Organic fertilizer is rich in organic matter, phosphoric acid and a variety of organic weak acids, which can turn insoluble phosphorus into soluble phosphorus. It not only greatly improves the utilization rate of phosphate fertilizer, but also effectively overcomes the problem of phosphate fertilizer burning seedlings. 2. Apply in combination with nitrogen fertilizer, potassium fertilizer, and zinc fertilizer...

Key Winter Management Techniques for Intercropping Welsh Onions in Wheat Fields
In early autumn the weather turns cool and the onions begin vigorous growth, but the temperature is still relatively high and the plants grow slowly. Their water demand is not high, so they should be watered sparingly. Watering should be done in the morning and evening; never water at noon, as this suddenly lowers the soil temperature and affects root growth. In late August, when the average temperature in North China is below 24°C, Welsh onions...

Does applying chlorsulfuron to wheat fields affect cotton?
Chlorsulfuron is a sulfonylurea herbicide with high herbicidal activity, mainly used in wheat and flax fields to control annual monocotyledonous and dicotyledonous weeds. In China, it is currently restricted to use only in wheat fields in the wheat-rice rotation areas of the Yangtze River basin. It is not easily decomposed in soil, and its residual effect lasts up to 6 months. Crops such as cotton, peanut, soybean and vegetables are sensitive to this herbicide. When chlorsulfuron is applied to wheat fields and sensitive crops such as cotton are planted in the following crop, phytotoxicity of varying degrees will occur. In wheat fields where chlorsulfuron has been applied, it is best not to transplant cotton; other crops with strong tolerance can be planted instead.
