Abstract

The invention discloses a pyrazosulfuron ethyl-fentrazamide herbicide composition for weeding in the paddy field. A weight part ratio of pyrazosulfuron ethyl to fentrazamide is in a range of 5: 1 to 1: 5 and preferably, the weight part ratio is 3: 2. Compared with the single-ingredient herbicides, the pyrazosulfuron ethyl-fentrazamide herbicide composition has more obvious effects, reduces an herbicide use amount, reduces the adverse influence produced by herbicides on the ecological environment, has an important meaning for comprehensive control of resistance of weed and has large economic and social benefits.

Description

Technical field [0001] The invention involves a paddy field herbicide composition, which is based on pyrazoneulum and tetrazolide strawamine as effective ingredients to prevent the one -year weeds of rice fields. Background technique [0002] Chemical method weeding is one of the main means to control weeds in agriculture.In recent years, due to the large -scale use of some herbicide varieties, many weeds have produced anti -drug resistance.At the same time, the weeds of weeds are complicated. Not only are the annual and perennial weeds mixed, but also the herbs, vines and shrubs, but also different ginseng ginseng. Seeds, young and old weeds occur, so the herbicide varieties are separate alone.When used, it will show a certain number of defects and limitations. [0003] Pyrodolon is a sulfonic herbicide. It is a selective internal and conductive herbicides. It is mainly absorbed through the root system. It is rapidly transferred in the weed plant to inhibit growth and weeds grad...
