Abstract

The invention discloses a composition for controlling cornfield broad-leaved weed and is characterized in that the composition comprises active ingredient A and B, wherein the active ingredient A is 4-chloro-2-oxidbenzothiazole-3-ylacetate and the active ingredient B is one of or a plurality of tribenuron-methyl, thifensulfuron-methyl, bensulfuron-methyl, monosulfuron, monosulfuron-ester and the like.The composition provided in the invention has a broad weed-killing range, has a high activity to broad-leaved weed which is hard to control, and can effectively control broad-leaved weeds such as sticky willie, starwort, crickweed, descurainia, shepherd's-purse, vetch, lamium, corn gromwell, conical silene herb, pennsylvania bittercress herb, queshecao, fallopia convolvulus, brooklime, chorispora tenella, silene conoidea, pigweed, armstrong, xanthium sibiricum and the like.The composition also has advantages of safety to wheat, low toxicity, low residual, wide pot life and the like.Furthermore, the composition reduces employ dosage of each active compound, reduces the cost, enhancing the security of succession crop and has favorable economic effectiveness and ecological benefit.

Description

technical field [0001] The invention belongs to a herbicide, in particular to a herbicide composition for controlling broad-leaved weeds in wheat fields. Background technique [0002] Wheat is an important grain crop in my country, with an annual planting area of ​​about 30 million hectares and an output of about 100 million tons, accounting for more than 20% of the total grain output. In recent years, the occurrence of weeds in wheat fields is large and harmful, seriously affecting the yield and quality of wheat. According to incomplete statistics, the area of ​​wheat field weed damage in my country accounts for more than 30% of the total wheat area, and the annual yield loss accounts for about 15% of the total wheat output. Wheat field weed damage has become one of the important factors restricting the high yield of wheat. [0003] There are more than 200 types of weeds in wheat fields, including grass weeds such as A. chinensis, as well as Artemisia annua, chickweed, she...
