Abstract

The invention belongs to the technical field of pesticides, and relates to a weeding composition. The composition is characterized by comprising propyrisulfuron and orthosulfamuron two active ingredients. The composition can be used for preparing water dispersible granules and dispersible oil suspensions and enlarging the weeding spectrum, is remarkable in weeding effect and long in durability, and has a remarkable synergetic effect.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition of promasulfuron-methyl and rimsulfuron-methyl. 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 Na...
