Compound herbicide for paddy field

Abstract

The invention discloses a compound herbicide for a paddy field. The compound herbicide is characterized by consisting of the following effective ingredients in percentage by weight: 75 percent of thifensulfuron and 25 percent of bromoxynil octanoate. The compound herbicide has the advantages that weed species can be effectively expanded, the herbicide has an effect on weeds of different types at different periods, the application frequency and the application dosage are reduced, the agricultural cost is reduced and the pollution is reduced.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound herbicide for paddy fields. Background technique [0002] Thifensulfuron-methyl is an effective and selective post-emergence stem and leaf treatment agent, which can be used in cereal crops to control one-year-old broad-leaved weeds. It is mainly absorbed and transmitted through the leaf surface and roots of the weeds. [0003] Bromoxynil octanoyl is a contact herbicide for selective post-emergence stem and leaf treatment. It is mainly absorbed by leaves and conducts extremely limited conduction in plants. By inhibiting the various processes of photosynthesis, including inhibiting photosynthetic phosphorylation and electron transfer, In particular, the Hill reaction of photosynthesis causes rapid necrosis of plant tissues to achieve the purpose of killing weeds. [0004] When the above two herbicides are used alone, the weeding is relatively simple, and the application time...

AI Technical Summary

Problems solved by technology

[0004] When the above two herbicides are used alone, the weeding is relatively simple, and the application time is relatively harsh, and the effect of weeding can only be achieved after repeated application. Therefore, the application cost is high and the phytotoxicity to crops is relatively large.
