A rice field herbicide

Abstract

The invention discloses a weedicide for rice paddy fields, of which the effective components are cyhalofop-butyl, pyribenzoxim and carfentrazone-ethyl. The weedicide is composed of the following components in percentage by weight: 1-30% of cyhalofop-butyl, 1-20% of pyribenzoxim, 1-10% of carfentrazone-ethyl and the balance of pesticide adjuvant. The weedicide is suitable for preventing and removing annual weed in rice paddy fields, has obviously better preventing and removing effects than a single agent, and has the advantages of wide weeding spectrum, higher actual effect, lower drug resistance for weed, time saving, labor saving and the like.

Description

technical field [0001] The invention relates to a paddy field herbicide, the active ingredients of which are cyhalofop-ethyl, saflufenacil and mefentrazone. Background technique [0002] Chemical method of weeding is one of the main means of controlling weeds in paddy fields. Weeds in paddy fields have complex grass phases, grass weeds, broad-leaved weeds, sedges and other weeds are mixed, and the use of a single herbicide cannot solve the weeds in paddy fields, and all of them will show some defects and limitations. Through the scientific mixing of different types of herbicides, it has the advantages of improving the weeding spectrum, improving the actual effect, and saving time and labor. [0003] Cyhalofop-ethyl is a variety of aryloxyphenoxypropionic acid herbicides with high safety to rice. Cyhalofop-ethyl is also a systemic conductive herbicide, which is absorbed by the leaves and leaf sheaths of plants, conducts in the phloem, accumulates in the meristem area of ​​...
