Embodiment 1

[0027] The herbicide composition raw material consumption of the present embodiment is:

[0028] The herbicide containing amiloride, glyphosate and imazethapyr comprises the following active ingredients in parts by weight: 15 kg of amiloride, 50 kg of glyphosate, and 20 kg of imazethapyr.

[0029] Mix it with starch, bentonite, sodium carboxymethyl starch and add it to the conical mixer to mix evenly, then pulverize it through the jet mill, and then mix the pulverized material through the conical mixer. Mesh standard sieve to obtain wettable powder.

[0030] The weight percentage of the active ingredients of the herbicide in the preparation is 32%.

Embodiment 2

[0032] The herbicide composition raw material consumption of the present embodiment is:

[0033] Amiloride 10kg, glyphosate 30kg, imazapyr 1kg;

[0034] Add Tween 18, alkylnaphthalene sulfonic acid, polyvinylpyrrolidone and kaolin into the conical mixer and mix evenly, then pulverize through the jet mill, and the pulverized material is then mixed through the conical mixer, and the mixed material is fine 98% pass through a 600-mesh standard sieve, put into a kneader and knead into a plastic material, and finally put this material into an extrusion granulator to extrude and granulate, after granulation, dry and sieve to obtain water-dispersible granules agent.

[0035] The main active ingredient of the herbicide has a weight percent content of 88% in the preparation.

Embodiment 3

[0037] The herbicide composition raw material consumption of the present embodiment is:

[0038] Amiloride 30kg, glyphosate potassium salt 30kg, imazethapyr 2kg.

[0039]Together with epoxy propylene block copolymerization, carboxymethyl cellulose, polydimethylsiloxane, propylene glycol, and water, they are added to the conical mixer and mixed evenly, and then crushed by a jet mill. The crushed material is then passed through Conical mixer mixing, the mixed material fineness 98% passes through the 600 mesh standard sieve, put into the kneader to knead into plastic material, and finally put the material into the extrusion granulator to extrude and granulate, after granulation, pass through After drying and sieving, water-dispersible granules are obtained.

[0040] The main active ingredient of the herbicide has a weight percent content of 50% in the formulation.

Abstract

The invention provides a weeding composition containing picloram, glyphosate and imazapic. The herbicide composition is prepared from the following effective components in parts by weight: 10-35 parts of picloram or salt thereof, 20-45 parts of glyphosate or salt thereof and 1-20 parts of imazapic. The composition can be prepared into wettable powder, soluble powder, soluble granules, water dispersible granules, emulsion in water and water aqua. The composition has the advantages that the composition has a special effect on cyperaceae and broadleaf weeds after being compounded, the weeding speed is increased, the weed control spectrum is expanded, and the composition is convenient and flexible to use, labor-saving, money-saving, economical and practical. The weeding composition is suitable for preventing and treating annual weeds such as lalang grass rhizome, fortunella margarita, myrtle, cyperus rotundus and crab grass.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a herbicide composition using amiloride, glyphosate and imazethapyr as active ingredients. Background technique [0002] Amiloride is a pyridine herbicide. After application, amiloride can be quickly absorbed and transmitted through leaves and roots. It mainly acts on nucleic acid metabolism, deforms the structure of chloroplasts and other organelles, and interferes with protein synthesis. Act on meristem activities, etc., and finally lead to plant death. Most broad-leaved crops except cruciferous crops are sensitive to this product. The English common name of amiloride is picloram, its chemical name is: 4-amino-3,5,6-trichloropyridinecarboxylic acid, its CA registration number: 1918-02-1, and its molecular formula is C 6 h 3 Cl l3 N 2 o 2 , molecular weight 291.2, its structural formula is: [0003] Glyphosate is a systemic chronic broad-spectrum herbicide that mainly ...
