Embodiment 1

[0025] Example 1: 25% clopyralid · acifluorfen oil suspension concentrate

[0026] The components of the pesticide composition containing clopyralid and fluorfen are: 20% clopyralid, 5% ethoxyfluorfen, 5% phenethylphenol polyoxyethylene ether, lignin sulfonate 8% Sodium Oleate, 5% Epoxidized Soybean Oil, 5% Organic Bentonite, 100% Methyl Oleate.

[0027] After adsorption and mixing of clopyralid and filler, other above-mentioned materials (except organic bentonite) are added into the reaction kettle mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding, and the fineness of the ground materials is After 98% pass through 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, it can be made into 25% clopyralid · fluorfen oil suspension concentrate .

Embodiment 2

[0028] Example 2: 60% Clopyralid Suspending Concentrate

[0029] The components of the pesticide composition containing clopyralid and fluorfen are: 40% clopyralid, 20% oxyfluorfen, 5% phenethylphenol polyoxyethylene ether, lignin sulfonate Sodium phosphate 8%, ethylene glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0030] After adsorption and mixing of clopyralid and the filler, other above-mentioned materials (except xanthan gum) are added into the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding, and the ground materials are fine The material is discharged after passing through 1-5um with a density of 98%. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, it can be made into 60% clopyralid · fluorfen suspension agent.

Embodiment 3

[0031] Example 3: 50% clopyralid · acifluorfen wettable powder

[0032] The components of the pesticide composition containing clopyralid and fluorfen are: 15% clopyralid, 35% oxyfluorfen, 2% sodium lauryl sulfate, butyl naphthalenesulfonic acid Sodium 3%, Calcium Lignosulfonate 5%, Silica 5%, Kaolin to 100%.

[0033] After the clopyralid filler is adsorbed and mixed, it is added to the conical mixer together with other above-mentioned materials and mixed evenly, and then pulverized by the jet mill, and the pulverized material is then mixed by the conical mixer, and the fineness of the mixed material is 98 % Pass through a 325-mesh standard sieve to obtain 50% clopyralid · acifluorfen wettable powder.

Abstract

The invention discloses a pesticide composition containing clopyralid and fluoroglycofen-ethyl and application thereof. Clopyralid and fluoroglycofen-ethyl are used as active components of the pesticide composition; the mass ratio of clopyralid to fluoroglycofen-ethyl is (2-20) to (2-20). The pesticide composition shows an obvious synergetic effect in the ratio range; the application dosage of the pesticide is reduced; the pesticide application frequency is reduced; the pesticide cost is reduced; the adverse effects of the pesticide on the ecological environment are reduced; the defects and the limitations of the application of single dosage are remedied; the weed control spectrum is expanded; various weed problems can be solved by applying the pesticide for one time; the service life of the pesticide is prolonged; the pesticide composition has great significance on comprehensive treatment of the weeds; the clopyralid and the fluoroglycofen-ethyl are mixed in application, so that the pesticide effect can be rapidly exerted; the pesticide composition is long in lasting period and low in application cost, and can be used for preventing and treating the broadleaf weeds of rape fields.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a pesticide composition containing clopyralid and carboxyfluorfen for controlling weeds in rape fields. Background technique [0002] Rapeseed ranks first among the five major oil crops in my country. Its production has a long history and is an important source of edible oil and protein feed. Weed damage is a key factor restricting the yield and quality of rapeseed. In particular, the proliferation of broadleaf weeds seriously threatens the safe production of rapeseed. At this stage, chemical control is the leading measure for the prevention and control of farmland weeds. The herbicide varieties used to control broadleaf weeds in rapeseed fields are mainly single-agent herbicides such as clopyralid, clopyralid and amlopyralde. It is very easy to use them alone for a long time. As a result, the sensitivity of common broadleaf weeds in rape fields is reduced, resulti...
