Paddy field herbicide mixture

Abstract

The invention belongs to the field of agricultural herbicides, and particularly discloses a paddy field herbicide mixture. The paddy field herbicide mixture is characterized in that: the active components of the paddy field herbicide mixture include 0.5 to 90 percent of component A, 0 to 90 percent of component B and 0 to 90 percent of component C in part by weight, wherein the component A is clomazone, the component B is cyhalofop butyl ester or pfenoxaprop-ethyl, and the component C is one of bensulfuron-methyl, pyrazosulfuron-ethyl and carfentrazone-ethyl. The paddy field herbicide mixture has a remarkable synergistic effect and the effect of increasing the weed-killing speed, prolongs the persistent time, achieves a prevention and elimination effect on a variety of gramineous weeds and latifolious weeds in paddy fields, and is low in toxicity, the weed control spectrum is broadened, and the dosage is remarkably reduced.

Description

(1) Technical field [0001] The invention belongs to the field of pesticide herbicides, in particular to a compound herbicide for paddy fields. (2) Background technology [0002] Since around 1950 when 2,4-D and 2M4Cl were widely used to control broad-leaved weeds in paddy fields, the varieties of herbicides used in paddy fields have developed rapidly, and the varieties have been continuously improved and perfected. Diphenyl ethers, sulfur Substitute carbamates, amides, quinoline carboxylic acids, sulfonylureas and other herbicides have formed a relatively complete chemical herbicide system suitable for different cultivation methods of rice, which has become indispensable and very important in the world's rice production. measures to increase production. [0003] However, with the continued use of many herbicide varieties in large areas of rice fields, many problems have also arisen, such as prominent weed resistance, a kind of barnyardgrass against propanil, quinclorac,...

AI Technical Summary

Problems solved by technology

[0003] However, with the continuous use of many herbicide varieties in large areas of rice fields, many problems have also arisen, such as prominent weed resistance, a barnyardgrass against propanil, quinclorac, butachlor, and carbapill. The resistance to sulfonylurea herbicides is relatively prominent. Recently, common weeds such as Cyperaceae, Cyperaceae, Alismaceae and other common weeds such as heteromorphous sedge, Yinglin, Sagittarius, Yujiuhua, and Coriaceae have produced sulfonylurea herbicides. Resistance makes the problem of weeding more complicated; the damage of perennial weeds has become an important problem, especially the perennial weeds of Cyperaceae; the control problems of old barnyardgrass and chinensis need to be solved; the weed killing spectrum of herbicide varieties needs to be expanded , and prolong the duration of soil treatment chemicals; the demand for herbicide varieties with broad spectrum, strong selectivity and easy use is more urgent
