Embodiment 195

[0030] Embodiment 195% glyphosate-bispyribac wettable powder

[0031] Add 94% glyphosate, 1% bispyribac, 2% sodium lignosulfonate, 1% sodium lauryl sulfate, and 100% bentonite to prepare 95% glyphosate-bispyribac wettable powder .

[0032] Mix glyphosate, bispyribac, dispersant (sodium lignosulfonate), wetting agent (sodium lauryl sulfate), and filler (bentonite), mix them evenly in a mixing tank, and then pulverize them with a jet mill. Mix evenly, can make wettable powder product of the present invention.

Embodiment 285

[0033] Embodiment 285% glyphosate-bispyribac water dispersible granules

[0034] 80% glyphosate, 5% bispyribac, 5% fatty acid polyoxyethylene ester, 4% pull-off powder BX, 2% sodium carbonate, and diatomaceous earth to 100% to obtain 85% glyphosate-bispyribac Water dispersible granules.

[0035] Glyphosate, bispyribac, dispersant (fatty acid polyoxyethylene ester), wetting agent (pull-open powder BX), disintegrant (sodium carbonate), filler (diatomaceous earth), etc. are jet-milled together to obtain the required The particle size is obtained to obtain the granulation material. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying.

Embodiment 392

[0036] Embodiment 392% glyphosate-bispyribac suspension concentrate

[0037] Glyphosate 82%, Bispyribac 10%, Sodium Lignosulfonate 5%, Aluminum Magnesium Silicate 1%, C 10～20 Saturated fatty acids 0.3%, glycerin 2.5%, water added to 100%, prepared 92% glyphosate-bispyribac suspension concentrate.

[0038] Dispersant (sodium lignosulfonate), thickener (magnesium aluminum silicate), defoamer (C 10～20 Saturated fatty acids), antifreeze agent (glycerol) are uniformly mixed through high-speed shearing, glyphosate and bispyribac are added, and ball milled in a ball mill for 2 to 3 hours, so that the particle size is all below 5 μm, and the present invention is obtained suspension products.

Abstract

The invention discloses a mixed herbicide containing glyphosate and bispyribac-sodium, belonging to the technology field of pesticides. The herbicide takes glyphosate and bispyribac-sodium as main effective ingredients, wherein the mass ratio of glyphosate to bispyribac-sodium is (80-98):(0.1-10). The invention also discloses application of the mixed herbicide to post-emergence weeding in a paddy field. The mixed herbicide has wide weeding spectrum through mixture of weed killers, so as to improve the weeding effect; the mixed herbicide has the advantages of having quick effect, long lasting period, thorough weeding effect, low residue, low toxicity, safety, environment protection and the like and having capability of delaying pesticide resistance of the herbicide, and has prominent prevention and control effect on grassy weeds, broad leaf weeds, sedge weeds in the paddy field such as barnyard grass, leptochloa chinensis, difformed galingale herb, Eleocharis yokoscensis, Sagittaria pygmaea, Rotala indica and Marsilea quadrifolia, and therefore, the mixed herbicide is high-quality post-emergence chemical herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a mixed herbicide containing glyphosate and bispyribac and application thereof. Background technique [0002] Glyphosate (Glyphosate), scientific name: N-(phosphonomethyl) glycine, N-(phosphonomethyl) glycine, is a broad-spectrum organophosphorus herbicide. It is a non-selective systemic conduction herbicide for stem and leaf treatment. It is generally made into isopropylamine salt or sodium salt when used. Its herbicidal principle is mainly to inhibit the activity of enolacetonyl shikimelin phosphate synthase , thereby inhibiting the conversion of shikimelin to phenylalanine, tyrosine and tryptophan, interfering with protein synthesis and causing plant death. [0003] Bispyribac-sodium, also known as bispyribac-sodium salicylate, is a pyrimidine-type salicylic acid broad-spectrum herbicide developed by Japan Combination Chemical Company, chemical n...
