The ultra-efficient green herbicide monosulfuron ester, which was created by Nankai University's National Engineering Research Center for Pesticides for the past 12 years, passed the Ministry of Science and Technology's Agricultural Achievement Conversion Project “The Application of Green Herbicide Monosulfuronate Wheat Fieldsâ€. acceptance. This green pesticide, which is specially used for weed control in wheat fields, has reduced the amount of 100,000 mu of farmland weeds in the Wuqing area of ​​Tianjin by more than 95%.
Monosulfuron ester is another new herbicide variety created by Nankai University after the new sulfonylurea herbicide monosulfuron. Compared with the current major herbicides for wheat fields, mono-pyrimidine esters are characterized by a small amount of ultra-efficient, environmentally friendly, and moderate application costs. The monosulfuric acid ester preparation only requires 1.5 grams of active ingredient per acre. It can effectively control broad-leaved weeds such as weeds, leeks, leeks and other weeds. The herbicidal activity is high, and the average control effect is 96.7%. In 2011, the occurrence area of ​​broad-leaved weeds in Wuqing District of Tianjin was 450,000 mu, with an average density of 9.5 plants per square meter and a maximum density of 252 plants per square meter. Nankai University's research group established 10% monosulfuric ester WP in wheat fields and weeds demonstration zones in Daliang Town, Nancai Town, and Daxingchang Town. The demonstration area is 100,000 mu and the control effect is over 95%.
It is understood that monosulfuron esters are widely used for weed removal in wheat fields in northern China's provinces. At present, China has cumulatively promoted more than 200 million mu of farmland, achieved sales of 3 million yuan, and created social benefits of 160 million yuan. Not only does it increase food production, it also saves labor.
