Abstract

The invention discloses a nicosulfuron-containing cornfield herbicide composition, which contains, by weight, 10-20 parts of nicosulfuron, 3-9 parts of topramezone, 2-7 parts of alachlor, 1-5 parts of clopyralid and 60-100 parts of an auxiliary agent. According to the invention, nicosulfuron, topramezone, clopyralid and the auxiliary agent are used as the raw materials. Herbicidal activity and effects of the above raw materials are not just simply aggregated, but a remarkable synergistic effect is shown. According to the prepared nicosulfuron-containing cornfield herbicide composition, weed control spectrum can be broadened, and cornfield control effect is enhanced. In addition, the nicosulfuron-containing cornfield herbicide composition has good safety to crops and meets safety requirement of pesticide preparations.

Description

Technical field [0001] The present invention relates to the field of corn field herbicides, and in particular to a corn field herbicide composition containing nicosulfuron. Background technique [0002] Corn is not only an important food crop in my country, but also an important feed crop and industrial raw material. With the development of animal husbandry, food processing, brewing, biodiesel and other industries, the market demand for corn continues to increase. Weeds in corn fields are common and of various types. When corn is harmed by weeds in the seedling stage, the plants will be short, the stalks will be thin, and the leaves will be yellow, resulting in poor growth of corn in the middle and later stages and severe yield reductions. Therefore, chemical control of weeds in corn fields is all about sowing. It is carried out in two critical periods: pre-emergence and early post-emergence. Herbicides still play a very important role in the current weed management system ...
