Embodiment 1

[0036] Example 1: 51% flurafen propargyl pyrifluzal wettable powder (50:1)

[0037] Flurafen propargyl 50%, pyrifluzide 1%, sodium dodecylbenzene sulfonate 2.0%, white carbon black 5%, sodium lignosulfonate 10%, diatomaceous earth to make up to 100%.

[0038] Preparation method: According to the above formula, the active ingredients flumechlor, pyrizachlor, additives and fillers are fully mixed, and after being pulverized by an ultra-fine pulverizer, the corresponding wettable powder pesticide can be prepared.

Embodiment 2

[0039] Example 2: 31% flurafen-propargyl-pyrimifluzal emulsion in water (30:1)

[0040] Propyridine 30%, pyrifluzide 1%, N-methylpyrrolidone 5%, polyvinyl alcohol 0.8%, sorbitan fatty acid ester polyoxyethylene ether 5%, alkyl-diethylene glycol Alcohol ether-sodium sulfonate 2.5%, Nongru 2201 2%, ethylene glycol 5%, water to make up to 100%.

[0041] Preparation method: Add the original drug, solvent, emulsifier and co-emulsifier together to dissolve into a uniform oil phase. Mix water, antifreeze, etc. to form a homogeneous water phase. Under high-speed stirring, add the water phase to the oil phase or add the oil phase to the water phase to form a water emulsion with good dispersibility.

Embodiment 3

[0042] Example 3: 55% flurafen-propargyl-pyrimifluzan water-dispersible granules (10:1)

[0043] 50% of flumechlor propargyl, 5% of pyrizachlor, 12% of sodium formaldehyde condensate of methylene bis-naphthalene sulfonate, 5% of citric acid, 15% of soluble starch, gypsum supplemented to 100%.

[0044] Preparation method: Mix and pulverize the original drug, powdery carrier, wetting and spreading agent and binder, etc., and then spray dry or boil dry to obtain water-dispersible granules or add water and knead, then add a sieve with a certain specification Granulating in the granulator. Then dry and sieve (according to the range of the sieve) to obtain granular products.

Abstract

The invention discloses a cotton field herbicide composition containing flumioxazin and application thereof and belongs to the field of pesticide compounding. The herbicide composition disclosed by the invention is prepared from effective components A and B, wherein the effective component A is the flumioxazin; the effective component B is pyrithiobac-sodium, trifloxysulfuron or fluorochloridone; the weight ratio of the effective component A to the effective component B ranges from (50 to 1) to (1 to 50). The composition can be prepared into missible oil, liquid, an aqueous solution, concentrated emulsion, micro-emulsion, wettable powder, water suspension, oil suspension, water dispersible granules or soluble powder (granules). The herbicide composition disclosed by the invention is used for preventing and controlling annual and perennial broadleaf weeds and sedge weeds in a cotton field.

Description

technical field [0001] The invention relates to the field of agricultural compounding, and more specifically relates to a cotton field herbicide composition containing flufenazim and its application. Background technique [0002] Cotton is an important economic crop and textile fiber crop in China. Weeds in cotton fields can affect the yield and quality of cotton, and when the damage is serious, it can cause a reduction in cotton yield of up to 60%. In recent years, it has been difficult to control broad-leaved weeds and sedge weeds in Chinese cotton fields. Stem and leaf treatment agents such as quizalofop-p-p, haloxyfop-p-p, fluazifop-p-p, clethodim, ethenoxydim, etc. only have good control effects on gramineous weeds, but are ineffective against broad-leaved weeds . Although pyrimiazide and trifluxuron-methyl have good control effects on common broad-leaved weeds in cotton fields, their response speed is slow, and the control effects on some difficult-to-control broad-...
