HOE-107892 - Reference Information
| Overview | It is reported that the area of grass damage in wheat fields in China accounts for more than 55% of the planting area, and the serious damage area accounts for 28%, flat yield loss of 15%, of which, wheat and other gramineous weeds in wheat fields, in recent years, the rapid expansion of the area, resulting in a serious reduction in wheat yield or even no harvest. At the same time, with the continuous increase of labor costs in China, the use of herbicides to control weeds in wheat fields has become a necessary measure for wheat production. However, Gramineae weeds in wheat fields such as wheat and wheat are similar in genetic relationship, and herbicides are difficult to obtain high selectivity between wheat and grass weeds, resulting in a serious lack of herbicides that can be used to control Gramineae weeds in wheat fields. At present, China can be more effective in the prevention and control of wheat herbicide only methyl disulfuron, But methyl disulfuron high risk of wheat Phytotoxicity, easy to produce Phytotoxicity, therefore, the safety agent pyrazolyl Ester is usually added to the methyldisulfuron preparation, and the two are mixed and sprayed to protect the wheat, to improve the resistance of wheat to methyl two and no effect on wild oats and other weeds. Pyrazolyl ester (mefenpyr-diethyl) is a new herbicide safener, which was announced by the UK percent Plant Protection Conference in 1999. It is a pyrazole antidote developed by Aventis, barley is protected from Phytotoxicity, however, its mechanism of action is still inconclusive. |
| biological activity | Mefenpyr-diethyl is a herbicide safener used to protect crops against herbicide damage. |
| Use | is a safener for oxazolidinedione in wheat, barley, etc. |
