Compound herbicide and its use method

Abstract

A compound herbicide for paddy rice field is prepared from fenoxaprop-p-ethyl and cyhalofop-butyl. Its advantages are high effect, low dosage, low cost and high safety.

Description

technical field [0001] The invention relates to a compound herbicide, especially a paddy field herbicide composition, and at the same time, the invention also provides its application method, which belongs to the technical field of agricultural herbicides. Background technique [0002] With the continuous expansion of the planting area of ​​light cultivated rice such as direct-seeding rice, wheat interplanting rice, and throwing seedling rice, Qianjinzi has risen from a secondary weed in the past to a major malignant weed. Since the genia chinensis is more suitable for the "dry, wet and wet" light cultivation mode than rice, its occurrence area in paddy fields is expanding year by year, and its damage is becoming more and more serious. At present, whether or not the damage of D. chinensis can be effectively controlled has become the key to achieving high and stable yields of lightly cultivated rice.

Problems solved by technology

However, the biomass of Qianjinzi in the early stage is very small, and the plant height of Qianjinzi at the 3-leaf stage is less than 1cm, so it is easy to be ignored

In order to achieve a satisfactory control effect, it is necessary to increase the dosage of fenoxaprop-ethyl, and the increased dosage will inevitably cause phytotoxicity of rice, making it difficult to achieve the goal of "weeding and increasing income"
