Description

technical field

[0001] The invention belongs to the field of pesticide compositions, and in particular relates to a ternary herbicidal composition containing promasulfuron-methyl and an application thereof. Background technique

[0002] At present, the control of weeds in paddy fields in my country is still dominated by chemical means, supplemented by measures such as artificial weeding or biological control. Therefore, how to select safe, efficient and long-lasting herbicides is particularly important to effectively control weeds and ensure high and stable yields of direct-seeding rice.

[0003] Promethazone-methyl is a selective broad-spectrum sulfonylurea herbicide. After being absorbed by the roots, stems and leaves of weeds, it can inhibit the activity of acetolactate synthase and stop its growth until it dies. The agent was developed by Sumitomo Chemical Co., Ltd. in Japan. It obtained the original drug and product registration in my country in 2014, and carried out d...
