Abstract

The invention belongs to the technical field of pesticides, and relates to a weeding composition which is characterized by comprising two active components, namely, propyrisulfuron and fenothiocarb. The composition provided by the invention can be prepared into dispersible oil suspension and suspension, is remarkable in weeding effect, long in lasting period, wide in weeding range, free of remarkable cross resistance with conventional components, and remarkable in synergism.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a herbicidal composition containing promasulfuron-methyl and fenoxaprop-p-ethyl. Background technique [0002] Propyrisulfuron is a pyrimidine-based sulfonylurea herbicide developed by Sumitomo Chemical, Japan. It is mainly used in rice fields to control gramineous and broad-leaved weeds such as barnyardgrass. The product is used at a low dosage and is effective against certain weeds that are known to be resistant to sulfonylurea herbicides. [0003] Fenoxaprop-P-ethyl (fenoxaprop-P-ethyl) is a heteroepoxyphenoxypropionic acid herbicide, which mainly inhibits the synthesis of fatty acids by inhibiting the key enzyme of fatty acid synthesis - acetyl-CoA carboxylase . The drug is absorbed and transmitted to the meristem and the growth point of the root through the stem and leaf, and the effect is rapid. After 2-3 days of application, the growth stops, and the heart leaves turn...
