Embodiment 1

[0031] 15kg of amiloride, 30kg of glyphosate sodium salt based on glyphosate, 10kg of fenflurzone, 12kg of sodium lauryl sulfate, 8kg of sodium lignosulfonate, 8kg of sodium methylene bis-naphthalenesulfonate, White carbon black 18kg. First add white carbon black and mefentrazone into the mixer and mix evenly, then add amiloride, glyphosate sodium salt, sodium lauryl sulfate, sodium lignin sulfonate and methylene bis-naphthalene sulfonic acid The sodium is added into the mixer in turn and mixed thoroughly, and the uniformly mixed material is put into the jet mill and pulverized until the fineness reaches 325 mesh, and the wettable powder of the composition with an active ingredient content of 55% is obtained.

Embodiment 2

[0033] Amiloride 2.5kg, glyphosate sodium salt 60kg based on glyphosate, fenfluxazone 0.5kg, sodium lauryl ether sulfate 2kg, calcium lauryl sulfate 2kg, sodium dodecylbenzenesulfonate 4kg, light calcium carbonate 29kg. First add light calcium carbonate and fenflutrazone into the mixer and mix evenly, then add amilopyral acid, glyphosate sodium salt, sodium lauryl ether sulfate, lauryl calcium sulfate and dodecylbenzenesulfonate The sodium bicarbonate is sequentially added into a mixer and fully mixed, and the uniformly mixed material is added into a jet mill and pulverized until the fineness reaches 325 mesh, and a composition wettable powder with an active ingredient content of 63% is obtained.

Embodiment 3

[0035]Amiloride 10kg, glyphosate potassium salt 70kg based on glyphosate, fenflurzone 7kg, alkanolamide polyoxyethylene ether sulfonate 2kg, fatty alcohol polyoxyethylene ether sulfonate 2kg, dodecyl Sodium alkylbenzene sulfonate 1kg, attapulgite 8kg. First add attapulgite and mefentrazone into the mixer and mix evenly, then add amilorolic acid, glyphosate potassium salt, sodium alkanolamide polyoxyethylene ether sulfonate, sodium fatty alcohol polyoxyethylene ether sulfonate and sodium dodecylbenzene sulfonate are sequentially added into a mixer and fully mixed, and the uniformly mixed material is added into an airflow mill and pulverized until the fineness reaches 325 mesh, and a composition wettable powder with an active ingredient content of 87% is obtained.

Abstract

The invention discloses a pharmaceutical weeding composition and a preparation thereof. The pharmaceutical weeding composition comprises the following effective constituents in parts by weight: 10-150 parts of picloram, 300-700 parts of glyphosate and 1-100 parts of carfentrazone. The dosage forms of the pharmaceutical weeding composition are wettable powder, soluble powder, soluble granules, water dispersible granules and microemulsion. The pharmaceutical weeding composition has the advantages that the compounded composition has an obvious synergistic effect, the weeding speed is increased, the herbicide controlling spectrum is expanded, and the dosage and use frequency of herbicides are remarkably reduced. The pharmaceutical weeding composition is suitable for preventing and treating annual and perennial weeds such as cogongrass, bermuda grass, crab grass, diranopteris dichotoma and railway beggarticks herb.

Description

Technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, and in particular to a herbicidal pharmaceutical composition and its preparation. Background technique [0002] Amclopyridine is also called picloram, its common English name is picloram, its chemical name is: 4-amino-3,5,6-trichloropyridinecarboxylic acid, its CA registration number: 1918-02-1, molecular formula C 6 H 3 C l3 N 2 O 2 , with a molecular weight of 291.2, is a pyridine herbicide that can be rapidly absorbed and conducted through leaves and roots. It mainly acts on nucleic acid metabolism, and causes malformation of the chloroplast structure and other organelles, interferes with protein synthesis, and acts on meristem activities, etc. , eventually leading to plant death. Most broadleaf crops except cruciferous crops are sensitive to this product. [0003] Glyphosate is also known as Roundup and Zhencaoning, its common English name is glyphosate, CA registratio...
