Problems solved by technology

[0011] In actual use, saflufenacil has low activity on some perennial sedges, and some perennial weeds will be severely damaged after continuous use for many years, such as flat stalk, cow felt, Japanese sedge, etc.
The above weeds need to be controlled again, which is labor-intensive, time-consuming and labor-intensive
In addition, its weeding speed is slow. Although the growth of weeds can be inhibited after application, it usually takes 2 weeks for the weeds to die

Abstract

The invention relates to a synergetic herbicidal composition which comprises herbicidal active components of pyribenzoxim and 2-methyl-4-chloro-phenoxyacetic acid or a derivative thereof, wherein a weight ratio of pyribenzoxim to 2-methyl-4-chloro-phenoxyacetic acid or the derivative thereof is 100 : 1-1 : 100. The synergetic herbicidal composition is suitable for selective weed control weeds in beneficial crops such as rice. The synergetic herbicidal composition also can comprise a safety agent. Through binary compound of pyribenzoxim and 2-methyl-4-chloro-phenoxyacetic acid or the derivative thereof, the obtained novel composition can effectively overcome the defects that pyribenzoxim is used individually, enlarge herbicidal spectrum for weeds and delay the generation of resistance. The weeds in rice fields can be largely eradicated by applying the synergetic herbicidal composition at one time. The synergetic herbicidal composition is labor-saving, time-saving and effort-saving and has a certain effect for increasing both production and income for the rice. An enhanced effect in prevention of broad leaf weeds, grassy weeds and cyperaceae weeds in the rice fields is obtained.

Description

technical field [0001] The present invention relates to a synergistic herbicidal composition, which contains herbicidal active ingredients saflufenacil and dimethyltetrachlor or derivatives thereof, and is suitable for selectively controlling weeds in beneficial crops such as rice. Background technique [0002] Rice is one of the main food crops in the world. Nearly half of the world's population, including almost the entire population of East Asia and Southeast Asia, live on rice, and its production covers all continents except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. Rice is also the most important food crop in my country. my country's rice sowing area accounts for 1 / 4 of the country's food crops, about 35 million hectares per year, while the output accounts for more than half. Regardless of the planting area and output, it ranks first in my cou...
