Corn field weeding composite and application thereof

Abstract

The invention relates to the technical field of pesticides, in particular to a corn field weeding composite and application thereof. The composite comprises the following components: an effective active ingredient A, namely, benzene azole fluridone, an effective active ingredient B, namely, thifensulfuron methyl, and a safener compound C; the safener compound C is one or more of isoxadifen-ethyl, cyprosulfamide, mefenpyr-diethyl and furilazole. The components A, B and C of the weeding composite account for 1 to 95 mass percent, preferably, 10 to 80 mass percent, of the total corn field weeding composite. The weeding composite can effectively prevent and weed common weeds of a corn field, and particularly has remarkable preventing and weeding effects on digitaria sanguinalis, eleusine indica, setaria viridis and the like which have resistance to ALS inhibitor. According to the weeding composite provided by the invention, the weed control spectrum can be enlarged; the using amount can be reduced; the occurrence and the development of the pesticide tolerance and resistance of the weeds can also be retarded; the corn field weeding composite has an important great economic value and social significance.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a group of cornfield herbicide compositions containing fenfluroxyzone. Background technique [0002] Chemical weeding is the most economical and effective means of weed control in farmland. However, long-term continuous high-dose use of a single species or a single mode of action of chemical herbicides is likely to cause problems such as weed resistance and resistance evolution. Reasonable compounding or mixing of herbicide compounds has the advantages of expanding the spectrum of weeds, improving the control effect, delaying the occurrence and development of weed resistance and drug resistance, and is one of the most effective methods to solve the above problems. [0003] Thifensulfuron-methyl is a systemic conduction type post-emergence selective herbicide. It is a branched-chain amino acid synthesis inhibitor, which can inhibit the biosynthesis of valine, leucine, and is...

Problems solved by technology

These two herbicides have been used on corn for many years, and the resistance of weeds to nicosulfuron has begun to emerge. The activity of mesotrione is low and the herbicidal sp
