Embodiment 1

[0043] Example 1: Activity of Herbicide Compositions

[0044] Greenhouse potting method was used to study the herbicidal activity of cyhalofop-ethyl and fluroxypyr-isooctyl in different proportions on the main weeds barnyardgrass, snakehead sausage, heterocyphus and stephenia in direct-seeding paddy fields. The results are shown in Table 1 ,2.

[0046]

[0047]

[0048] Table 2 Types of combined effects of cyhalofop-ethyl and isooctyl fluroxylactate on weeds

[0049]

[0050] The results showed that the herbicidal activity of mixed cyhalofop-ethyl and isooctyl fluroxypyr was higher. The mixed use of the two agents has high herbicidal activity against barnyardgrass, snakehead sausage and stephenia chinensis, but is ineffective against heterocystic sedges. The analysis of the combined effects of the two showed that the combined effects of all the ratio treatments on ...

Embodiment 2

[0051] Embodiment 2: recipe example

[0052] Formula 1: cyhalofop-methyl 10%, isooctyl fluroxypyr acetate 20%, alkylphenol formaldehyde resin polyoxyethylene ether 10%, isomer C 13 Fatty alcohol 10%, the materials are mixed and then stirred, and then supplemented to 100% with 200# solvent to obtain 30% cyhalofop-methyl isooctyl emulsifiable concentrate.

[0053] Formula 2: 5% cyhalofop-ethyl, 20% isooctyl fluroxypyr, 3% ethylene oxide-propylene oxide block copolymer, 0.1% xanthan gum, 0.2% silicone defoamer, Stir the materials after mixing, dissolve into a uniform oil phase, add 5% ethylene glycol, make up to 100% with water, and stir to form a 15% cyhalofop-chlorfluroxylate isooctyl water emulsion.

Abstract

The invention discloses a herbicide composition, which is characterized by containing two active ingredients, namely cyhalofop-butyl ((R)-2-[4(4-cyano-2-fluorophenoxy) phenoxy]-butyl propionate and fluroxypyr-mepthyl (4-amino-3.5-dichloro-6-fluoro-pyridine-2-oxyacetic acid isooctyl ester); and a composition preparation for preventing and removing weeds of paddy fields can be prepared from the cyhalofop-butyl and the fluroxypyr-mepthyl with effective dose, solid or liquid carrier, auxiliary agent and other additive by a conventional method. The composition using the cyhalofop-butyl and the fluroxypyr-mepthyl has remarkable additive action, and can synthesize the combined action type, weeding activities and economic costs of the two agents by compounding the cyhalofop-butyl and the fluroxypyr-mepthyl.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides. The invention relates to a binary compound composition for controlling weeds in paddy fields, in particular to a composition of the herbicide cyhalofop-ethyl and isooctyl fluroxypyr and its application. Background technique [0002] Cyhalofop-ethyl (chemical name: (R)-2-[4(4-cyano-2-fluorophenoxy)phenoxy]-butyl propionate) belongs to aryloxyphenoxypropionic acid herbicides, It can effectively control grass weeds in paddy fields, and has special effects on Azalea chinensis. [0003] Isooctyl fluroxypyr acetate (chemical name: 4-amino-3.5-dichloro-6-fluoro-pyridine-2-oxo-octyl isooctyl) is a pyridine selective systemic conduction type post-emergence herbicide, suitable for It is used to control various broad-leaved weeds in crop fields such as wheat, barley, corn, grapes, orchards, pastures, woodlands, lawns, etc. It is ineffective against gramineous weeds and sedge weeds.
