Embodiment 1

[0015] Formulation example 1: 27.2% propanil·oxafenac emulsifiable concentrate (65:3):

[0016] Propanil 26%

[0017] Methamphetamide 1.2%

[0018] Fatty alcohol polyoxyethylene ether 12%

[0019] Alkylphenol formaldehyde resin polyoxyethylene ether 8%

[0020] Ethylene glycol 3%

[0021] Xylene 12%

[0022] Ethyl acetate 8%

[0023] Deionized water make up to 100%

[0024] The specific processing steps of the emulsifiable concentrate of the composition are as follows: after mixing and dissolving according to the above-mentioned formula in proportion, the mixture is mixed into a uniform and transparent phase by high-speed shearing to obtain the 27.2% propanil-oxamid emulsifiable concentrate of the present invention.

Embodiment 2

[0025] Formulation example 2: 29% propanil·oxafen dispersible oil suspension concentrate (28:1):

[0026] Propanil 28%

[0027] Methamphetamide 1%

[0028] Sodium lignosulfonate 7%

[0029] Alkylphenol formaldehyde ethoxylates 4%

[0030] Alkyl succinate 4%

[0031] Fumed silica 1%

[0032] Magnesium Aluminum Silicate 1%

[0033] Dibutyl phthalate 12%

[0034] Methyl Oleate Fill up to 100%

[0035] The specific processing steps of the dispersible oil suspension concentrate of the composition are as follows: after mixing and dissolving dibutyl phthalate and propanil according to the above formula, adding mineral oil, thickener, and emulsifier to mix, and mixing evenly by high-speed shearing , then add fenpyramid, continue to shear and mix, and then enter the horizontal sand mill to grind, so that the particle size of the preparation is all below 10UM, and the 29% propanil-oxazylazide described in the present invention is obtained Amine dispersible oil suspension concent...

Embodiment 3

[0036] Formulation example 3: 29.2% propanil·oxapropen suspoemulsion (28:1.2):

[0037] Propanil 28%

[0038] Methamphetamide 1.2%

[0039] Methyl Oleate 15%

[0040] Alkylphenol Ethoxylate Phosphate 2%

[0041] Calcium dodecylbenzenesulfonate 5%

[0042] Alkylphenol Ether Phosphate 4%

[0043] Silicone 1.5%

[0044] pH regulator 0.2%

[0045] Xanthan Gum 0.2%

[0046] Ethylene glycol 5%

[0047] Deionized water make up to 100%

[0048] The concrete processing steps of described suspoemulsion are:

[0049] 1. According to the above formula, dilute fenpyramid with methyl oleate, add an emulsifier and mix evenly to obtain an oil phase solution, then add an appropriate amount of deionized water to emulsify with a homogenizer to obtain an emulsion.

[0050] 2. Mix the dispersant, thickener, and defoamer according to the above formula, mix evenly through high-speed shearing, add propanil, continue shearing and mixing, and finally enter the third-stage grinding in the hori...

Abstract

The invention relates to a herbicide composition containing propanil and metamifop. The herbicide composition has synergistic effect. The mass ratio of propanil to metamifop is (220-300):(6-14), perferably, is (240-280):(8-12), and most perferably, is 280:12.

Description

technical field [0001] The invention belongs to the field of pesticide herbicide compounding, and specifically relates to a three-component compound herbicide composition containing propannil and fenpyramid as effective ingredients and an application thereof. Background technique [0002] In recent years, herbicide weeding in rice fields in my country has become more and more difficult, and the occurrence of drug-resistant weeds has become more and more serious. The outbreak range has become larger and larger, and the impact on production has become more and more serious. The main hazards of resistant weeds are as follows: 1. There are few herbicide alternatives for resistant weeds, which makes it more difficult to control weeds; 2. The losses caused by resistant weeds are large, which seriously leads to the failure of rice harvests; 3. 1. The amount of herbicides used increases, and the problem of phytotoxicity is prominent; 4. The area of ​​drug-resistant weeds expands rap...
