Sophosulfuron is a kind of sulfonioside type soybean field herbicide pre-emergence treatment soil can control the soybean field of cocklebur, Jianma, Li, Yao, loquat, field bindweed, iron leeks, solanum and other broadleaf weeds and Grass weeds and other grass weeds are the ideal soil treatment agents for controlling broad-leaved weeds in soybean fields. Since it is a soil treatment agent, it is generally limited by the temperature and humidity of the soil and affects the efficacy. Therefore, research and exploration have been conducted in this regard. The temperature and humidity of the soil can be measured and analyzed using a soil temperature and humidity recorder.
The herbicidal activity of the herbicide herbicide has little to do with the temperature, which is the same as the results of the test that I performed. Applying 1 gram of active ingredient per acre to conduct pre-emergence soil treatment, the efficacy of tarsulosin against madder was 86.7% at QC, 92.5% at 25C, and 92.4% at 35C. Therefore, as long as it is not a special low temperature, it will not affect the efficacy. Similar to the temperature test, soil water content was 40.4% at å·§%, control efficiency was 84.8% at 25%, control efficiency was 90.2% at 35%, and control effectiveness was 100% at 45%.
The temperature and humidity of the soil and the efficacy of the herbicide were analyzed by the soil temperature and humidity recorder. From this, it can be seen that the efficacy of the sulfuron-methyl is highly related to the humidity of the soil slope, the humidity is large, the efficacy is good, and the humidity is small and the efficacy is poor. Therefore, in order to achieve a better control effect, the soil moisture content should be at least 25%, otherwise it will affect the efficacy. The emergence of farmers in the Mudanjiang area reflects the poor efficacy of the sulfosulfuron, which was caused by the severe early spring in the Northeast. The application of sophos-ulduron must pay attention to the weather conditions, and administer spraying before or after the rain. If there is no rain, there will be more pairs of water, at least 50 kilograms or more of water per acre. Where conditions permit, it is best to measure the soil moisture first, and achieve the right remedy.
