Problems solved by technology

3. It is easy to degrade in the soil, with a short half-life, and will not cause phytotoxicity to subsequent crops (but some data show that the use of pentagon + tribenuron-methyl to control weeds in wheat fields will have a negative effect on subsequent crops of cotton, soybeans, and peanuts. , pepper and other broad-leaved crops are not safe)

Abstract

The invention relates to an herbicide composition, which is prepared from the following raw materials by weight: 15-25 parts of quinclorac, 20-40 parts of atrazine, 0.1-8 parts of isooctyl chloroflupirate, a necessary surfactant and a necessary carrier. Compared with the herbicide composition in the prior art, the herbicide composition of the invention has the following beneficial effects that themixed herbicide has advantages of expanded prevention and treatment spectrum, enhanced prevention effect, delayed drug resistance of weeds and the like, and is especially an herbicide with synergistic effect, wherein various effective components of the herbicide interact with each other, so that the effect during combination is superior to the theoretical sum of the independent use effects, and the double effects can be obtained with the half work in actual use so as to be well accepted by users; the herbicide composition has good applicability and is widely applied to various crop systems; and the herbicide composition has characteristics of convenient use, short preparation period, multiple effects, cost saving and labor intensity reducing.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a herbicide composition. Background technique [0002] In the process of agricultural production, unwanted plants (weeds) occur seriously, endangering the growth of target crops such as crops and trees, and affecting undesired vegetation plots (such as non-cultivated land, railways, roads, forest fire escapes, industrial sites, field sites, etc.) hospital, etc.) for normal use. Herbicides are the most economical, quick and effective method of controlling unwanted vegetation. [0003] The use of a single herbicide is likely to produce resistance or has a limited control spectrum, which cannot solve the harm of unwanted plants in actual production. [0004] Quiclorac (quinclorac) is a special selective herbicide for controlling barnyardgrass in paddy fields. It is a hormone-type quinoline carboxylic acid herbicide. The symptoms of weed poisoning are similar to those of auxi...
