In recent years, many herbicides have been used for weed control in wheat fields, eliminating the need for manual weeding. However, improper use of the herbicides will not only affect the weed control effect, but also cause phytotoxicity for tomorrow. Therefore, we must pay attention to three points for safe and efficient weeding:
First, the preparation of drug dilution
The preparation of the drug must adopt the double dilution method. Do not pour the drug first and then add water. This will allow the drug to be deposited on the suction pipe of the nebulizer, so that the concentration of the first sprayed drug solution is high, the drug injury is easy to occur, and the concentration of the drug after it is sprayed. Low, bad weeding effect. It is also not allowed to pour the medicine into the sprayer containing a lot of water, so that the WP tends to float on the water meter or form a small piece, and the distribution is not uniform, which can not only ensure the effect but also easily clog the spray hole during spraying.
Second, the liquid clean water preparation
The liquid must be prepared with clean water, depending on the circumstances. Soil treatment herbicide spray volume should be higher, 50 ~ 60 kg of mu mixed with water, stems and leaves of the herbicide conventional spray water can be less appropriate, mu water consumption is generally 30 to 45 kg is appropriate, lack of moisture When it is necessary to increase the amount of water, it will not be applied for the time being.
Third, the use of special sprayer
Herbicides are best used with special sprayers. If no special equipment is used, they must be soaked with quicklime or lime sulfur for more than 48 hours after spraying. Rinse with clean water before spraying other crops. The herbicide mixture must be selected flexibly according to the characteristics of the herbicide, the occurrence of weeds, and the growth stage of the crop, so as to avoid blindly mixing the herbicide and to use the mixture.
In the event of a phytotoxicity in wheat fields, the following methods must be used to quickly remedy:
1, spray water, when the clear herbicide spraying dose is too large, it should be sprayed with fresh water in a timely manner to remove residual foliage, reduce the concentration of herbicides in the crop to reduce injury, while strengthening the management of fertilizer and water.
2, Gram-free phytotoxicity to wheat, can immediately spray ferrous sulfate solution for treatment.
3. The phytotoxicity caused by contact herbicides can be sprayed with foliar fertilizers to promote the rapid recovery of the crops and thus reduce the phytotoxicity.
