Abstract

The invention belongs to the technical field of pesticides and relates to a herbicidal composition which is characterized by containing two active ingredients, namely propyrisulfuron and pyriftalid, wherein the herbicidal composition can be prepared into water dispersible granules and dispersible oil suspensions, expands the weeding spectrum, has significant weeding effect and long duration of efficacy, has no obvious cross-resistance with existing ingredients, and has significant synergistic effect.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a herbicidal composition with promasulfuron-methyl and clofenac as active components. Background technique [0002] Rice is the major cereal crop, and rice is the staple food for one-third of the world's population, accounting for almost two-thirds of its food. my country has a long history of rice production and is distributed in a vast area. The planting area spans five climatic zones from north to south: cold temperate zone, mid-temperate zone, warm temperate zone, subtropical zone and tropical zone. The total output ranks first in the world. Rice plays a pivotal role in production, and the stable and increased production of rice is of great strategic significance to my country's food security. With the large-scale planting of rice, the weeds in rice fields have attracted people's attention day by day. According to the report of the Food and Agriculture Organization of the United N...
