Problems solved by technology

At present, weeds in rice fields are usually controlled by increasing the amount of pesticides, which leads to further enhancement of resistance and further increase in the difficulty of control, and the accompanying problem of phytotoxicity is becoming more and more serious, causing serious economic losses to farmers

Abstract

The embodiment of the invention relates to a weeding composition and application thereof, and relates to the field of pesticides, the active ingredients of the weeding composition comprise cinmethylin and bentazone, and the weight ratio of cinmethylin to bentazone is 1: (0.01-90), optionally 1: (0.05-90), optionally 1: (0.05-69), optionally 1: (1-69), optionally 1: (1-49), optionally 1: (5-49), optionally 1: (9-27.5), optionally 1: (11.5-27.5), optionally 1: (1-27.5), optionally 1: (1-47.5), optionally 1: (1-47.5), optionally 1: (1-47.5) and optionally 1: (1-47.5). The ratio is 1: (11.5-24), optionally 1: (11.5-24), optionally 1: (13.75-24). Compared with singly used cinmethylin and bentazone, the herbicide composition disclosed by the invention has a remarkable prevention and treatment effect, the compounding of cinmethylin and bentazone pesticide has a remarkable synergistic effect, the prevention and treatment effect on weed damage is obviously superior to that of a singly used single agent, the use amount of the pesticide can be reduced, and the cost is reduced. The use cost and the environmental pollution are reduced.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a herbicidal composition and its application. Background technique [0002] At present, rice is one of the four most important food crops in my country. Weeds in rice fields compete with rice for nutrients and sunlight, which has always been the main factor affecting rice yield. Rational application of herbicides is one of the direct and effective means of weed removal, but limited by the safety of rice, the herbicide spectrum that can be applied is limited, and the use of a herbicide alone cannot completely and effectively control the occurrence of weeds in rice fields , with the excessive use of herbicides and the increase in the number of years of use, it is easy to cause residual toxicity to current crops or subsequent crops, and weeds will also develop resistance to these herbicides. [0003] In order to achieve the ideal control effect, the compounding of active ingredients of he...
