Embodiment 1

[0029] Example 1: Activity of the composition

[0030] The herbicidal activity of pyroxaprop-ethyl and isooctyl fluroxyacetate mixed in different proportions on the main weeds in wheat fields such as clubhead grass, scallops, scallops, and pigtails were studied by using the greenhouse pot method. See Table 1 and Table 2 for the results.

[0031] The control effect (%) of table 1 fenoxaprop-ethyl and fluroxypyr mixed with isooctyl weeds

[0032]

[0033] Table 2 Types of combined effects of fenoxaprop-ethyl and isooctyl fluroxyacetate on weeds

[0034]

[0035] The results showed that the herbicidal activity of fenoxaprop-p-ethyl and isooctyl fluroxyacetate was mixed. When the low dose of fenoxaprop-ethyl and the high dose of isooctyl fluroxypyr were treated with a certain ratio, it had certain antagonistic effect on grass weeds Clifax and syringa. The effects on weeds under other ratio treatments were additive. Among them, the best ratio is fenoxaprop-ethyl:isooctyl ...

Embodiment 2

[0036] Embodiment 2: recipe example

[0037] Formula 1: Fenoxaprop-P-P-P 5%, Isooctyl Fluroxypyr Acetate 10%, Mecloxazone 2.5%, Sodium Lignosulfonate 2%, Alkylphenol Formaldehyde Resin Polyoxyethylene Ether 10%, White Carbon black 1%, xanthan gum 0.1%, glycerol 2%, silicone defoamer 0.3%, water to make up to 100%. After the material is coarsely crushed and homogenized, it is ground by a sand mill until the particle size reaches the standard requirement, and then filtered to obtain 15% fenoxaprop-ethyl isooctyl diclofenac suspension concentrate.

[0038] Recipe 2: Fenoxaprop-P-P-P 10%, Isooctyl Fluroxypyr Acetate 30%, Metocloxazole 5%, Methylcellulose 5%, Sodium Lignosulfonate 3%, White Carbon Black 2%, Kaolin tops up to 100%. The material is ultrafinely pulverized to obtain 40% fenoxaprop-ethyl isooctyl wettable powder.

[0039] Formula 3: Fenoxaprop-P-P-P, 20% isooctyl fluroxypyr, 2.5% fenoxaprop, 10% 200# solvent oil, 3% polyoxyethylene fatty acid ester, silicone defoamer...

Abstract

The invention relates to a composition containing fenoxaprop-p-ethyl and fluroxypyr-meptyl, which contains two active ingredients of the fenoxaprop-p-ethyl and the fluroxypyr-meptyl, and the fenoxaprop-p-ethyl and the fluroxypyr-meptyl, as well as a solid or liquid carrier and auxiliaries are prepared into a composition preparation for preventing and removing weeds in wheat fields. The composition of the fenoxaprop-p-ethyl and the fluroxypyr-meptyl is used to generate significant additive effect, and the compounding of the two can comprehensively consider the joint action type of two medicaments, the herbicidal activity and the economic cost.

Description

technical field [0001] The invention relates to a pesticide composition, which is a binary compound composition for preventing and controlling weeds in wheat fields, in particular to a composition containing oxaprop-p-p-p-p and isooctyl fluroxypyr and its application, belonging to The technical field of pesticide herbicide. Background technique [0002] Fenoxaprop-p-ethyl (chemical name: 2-[4-(6-chloro-1,3-benzoxazol-2-yloxy)phenoxy]ethyl propionate) belongs to phenoxycarboxylic acid herbicides Its mechanism of action is to inhibit the synthesis of fatty acids, and it can be used to control annual and perennial grass weeds in various dicotyledonous crops, but it is ineffective against broad-leaved weeds. [0003] Isooctyl fluroxypyr (chemical name: 4-amino-3,5-dichloro-6-fluoro-pyridine-2-oxo-octyl) is a pyridine selective systemic conduction post-emergence herbicide , suitable for controlling various broad-leaved weeds in crop fields such as wheat, barley, corn, grapes, o...
