Problems solved by technology

[0002] The herbicide varieties containing a single active ingredient have different degrees of defects in the agricultural weeding process: continuous use is easy to produce resistance, the herbicidal spectrum is not wide enough, and it can only control monocotyledonous or dicotyledonous weeds, or can only control emerging weeds. Weeds or unemerged weeds cannot be controlled at the same time
But the cost is higher

Embodiment 1

[0024] Example 1. 60% betafluzal·glufosinate-ammonium (glufosinate-ammonium refined) water dispersible granules:

[0025] Tobaconazole 20%,

[0026] Glufosinate-ammonium (glufosinate-ammonium) 40%,

[0027] Sodium Lauryl Sulfate 4%,

[0028] Naphthalenesulfonate formaldehyde condensate 6%,

[0029] Ammonium sulfate 5%,

[0030] Defoamer 0.1%,

[0031] Kaolin topping up.

[0032] The preparation method is as follows: put the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, and then mix the pulverized materials through a conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve. Put it into a kneader to 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 60% betamethazone·(refined) glufosinate-ammonium water Dispersible granules.

Embodiment 2

[0033] Example 2. 22% methenamid-dimethenamid (purified dimethenamid) microemulsion:

[0034] Tobaconazole 2%

[0035] Dimethenamid (Phenyl Dimethenamid) 20%

[0036] Cyclohexanone 10%

[0037] Co-surfactant 10%

[0038] Surfactant 20%

[0039] Tap water replenished to 100%

[0040] The preparation method is: after fully dissolving the active ingredients benzopyramid and (refined) xylenoxam in a solvent, put in an emulsifier and a co-emulsifier and mix evenly, and finally add tap water and fully stir to obtain 22% benzene Methenamid · Dimethenamid (Pure Dimethenamid) microemulsion.

Embodiment 3

[0041] Example 3. 35% Metrachlor (refined) metolachlor emulsion in water:

[0042] Tobaconazole 5%

[0043] Metolachlor (smart metolachlor) 30%

[0044] 150# solvent oil 10%

[0045] EO-PO block polyether 3%

[0046] Ethylene glycol 3%

[0047] Defoamer 0.2%

[0048] Make up to 100% with deionized water

[0049] The preparation method is as follows: after dissolving the effective components of methazazole and (refined) metolachlor in a solvent, they are put into an emulsifier, mixed and stirred evenly to form a homogeneous liquid, which is used as an oil phase component; the antifreeze agent ethylene glycol, disinfectant The foaming agent and deionized water are mixed and stirred evenly, and used as the water phase part. Use a high-speed shearing machine to pump the oil phase into the water phase and shear it fully to obtain 35% metolachlor (refined) metolachlor water emulsion.

Abstract

The invention discloses a herbicidal composition containing Ethyl 3-(2-chloro-4-fluorine-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-3,6-dihydropyrimidine-1(2H)-yl)phenyl)-5-methyl-4,5-dihydroisoxazole-5-carboxylate. The herbicidal composition comprises two active components A and B, wherein the active component A is Ethyl 3-(2-chloro-4-fluorine-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-3,6-dihydropyrimidine-1(2H)-yl)phenyl)-5-methyl-4,5-dihydroisoxazole-5-carboxylate; the active component B is one component selected from the group consisting of glufosinate, refined glufosinate, oxyfluorfen, fluoroglycofen-ethyl, imazethapyr, dimethenamid, dimethenamid-p, metolachlor, refined metolachlor, butachlor, acetochlor and pyroxasulfone; and the mass ratio of A to B is preferably 1:1.5-10. The composition can be formulated into a plurality of dosage forms. The herbicidal composition of the invention is applicable to controlling annual and perennial weeds in garden land and uncultivated land. With compounding of the two active ingredients, the obvious synergistic effect is achieved, the control effect is improved, and the pesticide dosage is reduced.

Description

technical field [0001] The invention relates to a compounding technology of agricultural herbicide composition. Background technique [0002] The herbicide varieties containing a single active ingredient have different degrees of defects in the agricultural weeding process: continuous use is easy to produce resistance, the herbicidal spectrum is not wide enough, and it can only control monocotyledonous or dicotyledonous weeds, or can only control emerging weeds. Weeds or unemerged weeds cannot be controlled at the same time. Through the compounding of two or more active components, the control effect can be improved, the usage of active components can be reduced, the cost of control can be saved, the emergence of weed resistance can be delayed, the service life of the pesticide can be extended, and the pollution to the environment can be reduced. [0003] Application number: 201310267255X's invention discloses a herbicidal composition containing glufosinate-ammonium and saf...
