Example Embodiment

[0018] Preparation method embodiment one:

[0019]

[0020] The above formula is roughly pulverized according to the proportion and then enters the mixer to mix evenly, and then is pulverized by airflow to obtain 30% cyhalofop-butyl, saflufenacil, and carfentrazone wettable powder.

Example Embodiment

[0021] Preparation method embodiment two:

[0022]

[0023] The above formula is pulverized in advance according to the proportion, and then added to a sand mill for grinding, and after high shear mixing, a 20% cyhalofop-butyl·sflufenacil·Carfentrazone suspension is prepared.

Example Embodiment

[0024] Preparation method embodiment three:

[0025]

[0026] The above formula was dry pulverized, granulated, dried and sieved according to the proportion to prepare 60% cyhalofop-butyl, saflufenacil, carfentrazone water dispersible granules.

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 ​​...
