Embodiment 1

[0039] Example 1: Indoor bioassay test

[0040] According to Colby's equation (for evaluation of the expected effect of a particular composition, see S.R. Colby, "Calculating Synergistic and Antagonistic Responses of Herbicide combinations" Weeds 1967, 15, 20-22)

[0041]

[0042] A The survival rate or fresh weight residual rate (%) of the target weeds when A is used alone at a certain dose;

[0043] B The survival rate or fresh weight residual rate (%) of the target weeds when a certain dose is used alone;

[0044] C Survival rate or fresh weight residual rate (%) of target weeds when a certain dose is used alone;

[0045] Evaluation criteria: when the observed value of the survival rate (fresh weight residual rate) is less than the theoretical value, there is a synergistic effect (synergistic effect)

[0046] Toxicity determination of propanil, cyhalofop-ethyl, isooctyl and their compound to crabgrass (Digitarias anguinalis) and long barnyard barnyardgrass (Echinochloa...

Embodiment 2

[0066] Embodiment two: preparation embodiment

[0067] (1) 25% propanil, 15% cyhalofop, 5% fluroxypyr isooctyl aqueous suspension concentrate

[0068] Take 25% propanil%, 15% cyhalofop-methyl, 5% isooctyl fluroxypyr, 7% sodium naphthalenesulfonate, 8% fatty alcohol polyoxyethylene ether, 5% glycerol, deionized water Make up to 100%; pre-crushed the above formula according to the proportion, then put it into a sand mill for grinding, and prepared after high-shear mixing to prepare 25% propanil, 15% cyhalofop-methyl, 5% fluroxypyr isooctyl Ester aqueous suspension.

[0069] (2) 25% propanil, 15% cyhalofop, 5% fluroxypyr isooctyl dispersible oil suspension concentrate

[0070] Take 25% propanil%, 15% cyhalofop-methyl, 5% isooctyl fluroxypyr, 5% sodium lignosulfonate, 10% fatty acid polyoxyethylene ether, 3% glycerol, methyl oleate The ester is supplemented to 100%. After mixing them, high-speed shearing, dispersion, and sand grinding in a sand mill form a highly dispersed and ...

Embodiment 3

[0073] Embodiment Three: Application Embodiment

[0074] Table 5 Field efficacy test on controlling annual weeds in paddy fields. The dominant weeds in the field are barnyardgrass, bald barnyardgrass, crabgrass, and daughter of grasses, accounting for more than 95% of the total amount of grass weeds. The application method is Stem and leaf spraying method, the water consumption per mu is about 30 kilograms (weed 3-5 leaf stage).

Abstract

The invention relates to a synergistic weeding composition containing fluroxypyr-mepthyl. The active ingredients include an ingredient A, an ingredient B and an ingredient C, wherein the A is selectedfrom propanil; the B is selected from cyhalofop-butyl; the C is selected from fluroxypyr-mepthyl; the mass part ratio of the active ingredients A, B and C is (10 to 45):15:(1 to 10); the mass percentof the active ingredients in the weeding composition is 1 to 60 percent; the rest materials are pesticide assistants. The application dosage form of the weeding composition can be one kind of dosageform from a water suspension, a dispersible oil suspension, a water dispersion granule, wettable powder and missible oil. The weeding composition has the synergistic effect on paddy field annual weed,and is applicable to the prevention and the removal of the paddy field annual weed.

Description

technical field [0001] The invention belongs to the field of synergistic herbicidal compositions, in particular to a synergistic herbicidal composition containing active ingredients A, B, and C; wherein A is selected from propanil, B is selected from cyhalofop, and C is selected from fluroxypyr Isooctyl acetate. Background technique [0002] Propaniln is a highly selective contact herbicide of amides, which not only destroys photosynthesis of plants, but also inhibits respiration and oxygen phosphorylation, and interferes with nucleic acid and protein synthesis. As a result, the physiological functions of sensitive plants are affected, water loss is accelerated, leaves gradually wither, and finally die. [0003] Cyhalofop-buty is the only aryloxyphenoxypropionic acid herbicide that is highly safe to rice. Like other varieties of this class, it is also a systemic conductive herbicide. Absorbed by the leaves and leaf sheaths of the plant, conducted by the phloem, and accumul...
