Abstract
The invention relates to a synergistic weeding composition, and particularly relates to the synergistic weeding composition which is a ternary composition of pyribenzoxim, 2-methyl-4-chloro-phenoxyacetic acid or a derivative thereof, and bentazone, and used in rice fields. The synergistic weeding composition comprises three active ingredients consisting of (a) the pyribenzoxim, (b)the 2-methyl-4-chloro-phenoxyacetic acid or the derivative thereof, and (c)the bentazone in a weight ratio of 1-100: 1-100:1-100. The weeding composition also can comprise a safety agent. The weeding composition is prepared through ternary complex formulation of the pyribenzoxim, the 2-methyl-4-chloro-phenoxyacetic acid or the derivative thereof, and the bentazone, so that defects caused by single use of the pyribenzoxim can be effectively overcome, a weed killing spectrum for weeds is enlarged, and at the same time generation of drug resistance is postponed. The weeds in the rice fields can be basically removed by using the weeding composition for once, so that the weeding composition is labor saving, time saving, and effort saving, can alleviate some of the rural labor shortage, and at the same time can play a certain role in increase in both production and income of rice. The weeding composition shows an enhanced effect on the control of broadleaf weeds, gramineae weeds and cyperaceae weeds in the rice fields.
Description
technical field [0001] The invention relates to a synergistic herbicidal composition, in particular to a synergistic herbicidal composition compounded with saflufenacil, dimethyltetrachloride or derivatives thereof and bentazone and applied to paddy fields. 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 country's food crops. [00...
