Farmers and friends in the control of wild wheat, they must choose the regular manufacturers of pharmaceuticals and scientifically applied as required. According to the author's understanding, the currently registered agents for the control of wild wheat are mainly chlorsulfuron-methyl (tiger tiger or quinine), and thimesulfan (priority). The author believes that the following points should be noted when using:
1. Pay attention to the temperature difference. The optimal temperature for the use of xylazosulfuron is above 8°C, while the optimal temperature for the treatment with xyloxacin is above 2°C.
2. Note the difference in time. The optimal time for the use of metrazoxulfuron is 2-3 leaves for wheat (25 days after planting), and the best time for the use of furoxapol is more than 3-6 leaves of wheat (35 days after planting).
3. Pay attention to safety. Safety is not affecting the yield of wheat after application. After the herbicide application, the wheat seedlings sometimes appear temporary yellowing or seedlings. Under normal use conditions, the yellowing of the wheat disappears after turning green, generally does not affect the yield. The use of xylazosulfuron as soon as possible in the appropriate temperature range, the safety factor is relatively high, while the sulphur-oxime to be delayed at the right temperature as much as possible.
In the past few years, we have passed experiments. While spraying wild wheat medicines, adding suitable conditioners or foliar fertilizers can better prevent yellow seedlings or seedlings from appearing. . Such as Shuofeng 481, chlorophyll, love more income. Farmer friends may wish to try.
