Problems solved by technology

The herbicides related to the present invention for weeds in direct-seeding paddy fields have active ingredients such as pretilachlor, butachlor, bensulfuron-methyl, etc. These herbicides are used to control the weeds that occur in the early stage of direct-seeding paddy fields, and the effect is ideal , but cannot control weeds that occur in the middle
The weeds that occur in the mid-term mainly include stephenia, barnyardgrass, paspalum, water sedge, water chestnut and cloverleaf, etc. At present, there is a serious lack of herbicides for effective control of mid-term weeds

Abstract

The herbicide composition features its contained active components including fenoxaprop-P-ethyl in 0.6-60 wt% and pyrazosulfuron-ethyl in 0.5-50 wt%. It has wide herbicidal spectrum, and can preventand kill gramineous weed, cyperaceae weed and latifoliate weed. It has the features of powerful synergistic effect, safety to crop and environment, low cost, etc. It has especially effective preventing and killing effect on weeds in directly seeding rice field in its middle stage.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticide herbicides. 【Background technique】 [0002] There are many kinds of herbicides, but compound herbicides are widely used due to their advantages of broad herbicidal spectrum, strong synergistic effect and low cost. Compound herbicides are generally composed of two or more active components and corresponding conventional adjuvants. The herbicides related to the present invention for weeds in direct-seeding paddy fields have active ingredients such as pretilachlor, butachlor, bensulfuron-methyl, etc. These herbicides are used to control the weeds that occur in the early stage of direct-seeding paddy fields, and the effect is ideal , but cannot control weeds that occur in the mid-term. The weeds that occur in the mid-term mainly include stephenia, barnyardgrass, paspalum, water sedge, water chestnut and cloverleaf, etc. At present, there is a serious lack of herbicides for effective control of m...
