It is required that frost weather will not occur 1 week after application. In the low-temperature frost period, oxazolyl is applied, and the wheat seedlings are also susceptible to phytotoxicity, and the herbicidal effect is affected. Acetyl oxalate has a wide spectrum of herbicides, wide application period, good mixedness, high safety to wheat, and temperature change does not affect safety. It can be applied from October to April, from wheat 2 leaf stage to jointing Can be applied at any time. In winter, weeding can generally achieve better results with 20% to 30 grams of 15% acetylene oxalate wettable powder per acre.
For the control of broad-leaf weeds, the herbicidal rate is slow in the low temperature period, and the mixing of 2, 4 and 4 chlorine can increase the speed of killing grass, but it is generally not recommended to apply the two when the temperature is too low (less than 5 ° C). medicine. Difluoro-oxazolidine is stable at low temperature, even if the temperature is 2 ° C, it has stable efficacy; the drug is suitable for wide application, and can be applied from late November to late January.
