Problems solved by technology

In order to improve the control effect, different herbicide single agents are often mixed and used in the field according to their own experience, which lacks scientificity, the control effect is unstable, and phytotoxicity often occurs, resulting in reduced rice production and accelerated weed resistance. The production of medicinal properties has aggravated the pollution of the ecological environment

Embodiment 1

[0050] Embodiment 1: prepare compound herbicide aqueous suspension concentrate of the present invention

[0051] The implementation steps of this embodiment are as follows:

[0052] Weigh 26.5 parts by weight of propanil, 3 parts by weight of cyhalofop-methyl, 0.5 parts by weight of bensulfuron-methyl, 3.5 parts by weight of alkylphenol polyoxyethylene ether, 6.0 parts by weight of polyoxyethylene polyoxypropylene block compound, 1.5 parts by weight The parts by weight of xanthan gum and the water supplemented to 100 parts by weight are successively poured into the shearing kettle and sheared evenly for 40 minutes; the cut semi-finished product is ground through a grinder at normal temperature and pressure until the suspension rate reaches the standard, which is obtained A water suspension concentrate with a total content of propanil, cyhalofop-methyl and bensulfuron-methyl at 30.0% by weight.

Embodiment 2

[0053] Embodiment 2: prepare composite herbicide aqueous suspension concentrate of the present invention

[0054] Weigh 36.5 parts by weight of propanil, 4 parts by weight of cyhalofop-methyl, 1.5 parts by weight of bensulfuron-methyl, 3.5 parts by weight of alkylphenol polyoxyethylene ether, 5.4 parts by weight of polyoxyethylene polyoxypropylene block compound, 1.2 The parts by weight of xanthan gum and the water supplemented to 100 parts by weight are successively poured into the shearing kettle and sheared evenly for 40 minutes; the cut semi-finished product is ground through a grinder at normal temperature and pressure until the suspension rate reaches the standard, which is obtained A water suspension concentrate with a total content of propanil, cyhalofop-methyl and bensulfuron-methyl at 42.0% by weight.

Embodiment 3

[0055] Embodiment 3: Preparation of composite herbicide water dispersible granule of the present invention

[0056] Weigh 60.0 parts by weight of propanil, 1.0 parts by weight of cyhalofop-methyl, 2.0 parts by weight of bensulfuron-methyl, 4.2 parts by weight of wetting agent Tersperse 1004 (Huntsman), 5.8 parts by weight of dispersant Geropon T / 36 (Rhodia), 2.7 parts by weight Parts by weight of dispersant Tamol DN (BASF), 3.2 parts by weight of disintegrant carboxymethyl cellulose, 1.0 parts by weight of binder polyvinyl alcohol 1799, 10.0 parts by weight of ammonium sulfate and supplemented to 100 parts by weight of filler cornstarch, Pour into the mixer in turn and stir evenly for 30 minutes. Pass the uniformly mixed material through the airflow mill for airflow pulverization. After the end, mix the host material and the material collected by the dust collector again for 10 minutes; pour the remixed material into the mixing mixer and add tap water while stirring ( 12% by ...

Abstract

The invention relates to an herbicide composition for rice fields and application thereof; the herbicide composition comprises propanil, cyhalofop-butyl and bensulfuron methyl. The herbicide composition is significant to the comprehensive treatment of weed resistance, the defects and limits of the usage of a single agent are made up, the herbicide composition may be applied to rice field weeding to prevent and remove grassy, cyperaceous and broad-leaved weeds in the rice field through single use, and multiple effects of the single drug are achieved; the herbicide composition has wide herbicidal spectrum, good fast-acting property, low application cost and good rice safety, and is an ideal agent for treating stems and leaves in a rice field.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of pesticides. More specifically, the present invention relates to a herbicide composition for paddy fields, and also relates to the use of the herbicide composition. [0003] 【Background technique】 [0004] At present, in the main rice areas of my country, the weeds that are harmful to rice production mainly include grasses, sedges and broad-leaved grasses, such as barnyardgrass, sedge, and amaranth. Wait. In addition to soil sealing treatment (before emergence), these weed control methods are post-emergence stem and leaf treatment (post-emergence). , due to long-term use, the resistance has increased seriously, and the conventional dosage is only 30-40% effective against weeds of the Gramineae barnyardgrass genus, and basically ineffective against the weeds of the sedge and sedges; the control effect of cyhalofop-ester is ideal , But barnyardgrass control effect is poor, broad-leaved weeds and Cy...
