Abstract

The invention relates to a synergistic herbicide composition. The composition is suitable for selectively controlling weeds in beneficial crops such as rice. The synergistic herbicide composition includes the following herbicide active ingredients: pyribenzoxim and bentazone in a weight ratio of (100:1)-(1:100). The composition can also include safeners. Through binary compounding of pyribenzoxim and bentazone, the obtained new composition can effectively overcome the defects existing when pyribenzoxim is exclusively used, expand the weed control spectrum and also delay drug resistance, can basically remove the weeds in the rice fields after being used once, saves labor, time and effort, can partially relieve the condition of lack of labor in the countryside, further has certain effects on rice yield increase and gains effects on controlling the broad-leaf weeds, grassy weeds and cyperaceae weeds in the rice fields.

Description

technical field [0001] The present invention relates to a synergistic herbicidal composition containing saflufenacil and bentazone as herbicidal active ingredients, which 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 country's food crops. [0003] The...
