Problems solved by technology

[0004] In practical application, saflufenacil is used to control various gramineous weeds and some broad-leaved weeds such as barnyardgrass and A. praecox, but the weeding speed is slow and the efficacy is not very satisfactory; Oxaamine can control a variety of broad-leaved weeds, but is ineffective against grassy weeds

Abstract

The invention relates to the technical field of pesticides and discloses an herbicide composition containing pyribenzoxim and florasulam. The herbicide composition is used for the wheatland and contains pyribenzoxim and florasulam as two active components. The herbicide composition comprises 0.5 to 75wt% of pyribenzoxim and florasulam, and a weight ratio of pyribenzoxim to florasulam is in a range of (8: 7) to (120:1). The herbicide composition is used for prevention and removal of weeds in the wheatland, has a reasonable formula, obvious synergism, a wide weed removal range and a fast weed removal rate, slows down herbicide resistance production, has good safety to crops, and satisfies pesticide preparation safety requirements.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and relates to a herbicide composition, in particular to a herbicide synergistic composition containing two active ingredients of saflufenacil and florasulam. Background technique [0002] Weeds are an important part of the agricultural ecosystem, competing with crops for glory, fertilizer, and water, which is one of the important factors affecting crop growth and resulting in yield reduction. In recent years, with the changes in wheat cultivation systems, fertilization and sowing methods, weeds in wheat fields are very prominent, causing great losses to crop production every year. At the same time, the weed community and dominant populations have also changed. For example, crabgrass, kanmai, barnyardgrass, Cyperus cyperi, water peanuts, and knotweed have risen to dominant populations, and some have become malignant weeds. In order to reduce the loss of crops and increase the average...
