1. Bendazole: Due to corn seedling pre-emergence amide herbicides and postemergence nicosulfuron-based herbicide for many years a large number of single use of some of the less common broadleaf weeds and sedge development is growing, incense monkshood, Convolvulaceae, sasaki, purslane, endangered weeds and other malignant weeds continue to emerge. Touch herbicides such as imazamox and imazapyr have good activity against weeds that are resistant to sulfonylurea herbicides and have a half-life in the soil of only a few hours and are very safe for the next crop. In addition, the southern part of the corn intercropping soybean more, conventional cornfield post-emergence herbicides can not be used, and weeds can be used, which is due to grasses
