Embodiment 195

[0032] Embodiment 195% glyphosate-bispyribac-dimethyltetrachlor wettable powder

[0033] Add 90% glyphosate, 1% bispyribac, 4% dimethyltetrachloride, 2% sodium lignosulfonate, 1% sodium lauryl sulfate, and bentonite to 100% to obtain 95% glyphosate - Bispyribac-dimethyltetrachloride wettable powder. Among them, dimethyltetrachloride exists in the form of sodium salt.

[0034] Mix glyphosate, bispyribac, dimethyltetrachloride, dispersant (sodium lignosulfonate), wetting agent (sodium lauryl sulfate), and filler (bentonite), and mix them evenly in a mixing tank. The wettable powder product of the present invention can be made after being pulverized by a pulverizer and mixed evenly.

Embodiment 285

[0035] Embodiment 285% glyphosate-bispyribac-dimethyltetrachloride water dispersible granules

[0036] 80% glyphosate, 3% bispyribac, 2% dimethyltetrachloride, 5% polyoxyethylene fatty acid ester, 4% pull open powder BX, 2% sodium carbonate, diatomaceous earth added to 100%, 85% prepared Glyphosate-bispyribac-dimethyltetrachloride water dispersible granules. Among them, dimethyltetrachloride exists in the form of sodium salt.

[0037] Combine glyphosate, bispyribac, dimethyltetrachloride, dispersant (polyoxyethylene fatty acid ester), wetting agent (pull-open powder BX), disintegrant (sodium carbonate), filler (diatomaceous earth), etc. The required particle size is obtained by jet crushing, and the material for granulation is obtained. 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

[0038] Embodiment 392% glyphosate-bispyribac-dimethyltetrachlor suspension concentrate

[0039] Glyphosate 81%, bispyribac 10%, dimethyltetrachlor 1%, sodium lignosulfonate 5%, aluminum magnesium silicate 1%, C 10～20 Saturated fatty acids 0.3%, glycerol 2.5%, water was added to 100%, and 92% glyphosate-bispyribac-dimethyltetrachloride suspension concentrate was prepared. Among them, dimethyltetrachloride exists in the form of isooctyl ester.

[0040] Dispersant (sodium lignosulfonate), thickener (magnesium aluminum silicate), defoamer (C 10～20 Saturated fatty acids), antifreeze (glycerol) are uniformly mixed by high-speed shearing, add glyphosate, bispyribac, and dimethyltetrachloride, and ball mill in a ball mill for 2 to 3 hours, so that the particle size of all particles is below 5 μm , make the suspension concentrate product of the present invention.

Abstract

The invention belongs to the technical field of pesticides, and discloses a composite herbicide containing glyphosate, bispyribac-sodium and agroxone. The coopoiste herbicide takes glyphosate, bispyribac-sodium and agroxone with the mass ratio of (80-98): (0.1-10): (0.1-10) as main effective components. The invention also discloses application of the composite herbicide in rice post-emergence weeding. By mixing herbicides, the composite herbicide is expanded in the weeding spectrum, improved in the weeding effect, quick in taking effect, long in the lasting period, delayed in resistance to drugs, thorough in the weeding effect, low in residue and toxicity, safe and environmentally friendly, and obvious in effect on controlling paddy field gramineous weeds such as galium aparine, barnyard grass, arrowhead, difformed galingale herb, moleplant seed, heleocharis yokoscensis, rotala indica and marsilea quadrifolia L as well as broad leaved weeds and sedge weeds.

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, bispyribac and dimethyltetrachloride and an 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 Ch...
