Embodiment 1

[0030] A compound herbicide comprising the following components by mass fraction: 3% trifluxysulfuron-methyl, 5% pyrizachlor, 5% quizalofop-p-ethyl, 8% beta-halofop-pyl, 9% adjuvants, Solvent 70%.

[0031] Among them, the auxiliary agent is an emulsifier, and the emulsifier contains the following components by mass fraction (accounting for the total mass): S-40 4%, T-80 3%, Nongru 606 1% and Nongru 500# 1%; the solvent is methyl oleate.

[0032] The preparation method of the compound herbicide in this example comprises: according to the above percentages, mixing triflupyrsulfuron-methyl, pyriflux-methyl, quizalofop-p-ethyl, adjuvants and solvents together, and after ball milling and sand milling, trifluorosulfuron-methyl is obtained. pyrisulfuron-methyl, pyrimiazin, quizalofop-p-ethyl oil suspension concentrate; add high-efficiency haloxyfop-pylene and additives into the preparation kettle, and stir evenly to obtain high-efficiency haloxyfop-methyl emulsifiable oil; then add ...

Embodiment 2

[0035] A compound herbicide comprising the following components by mass fraction: 10% triflusulfuron-methyl, 15% pyriflux-methyl, 8% quizalofop-p-ethyl, 10% beta-halofop-pyl, 15% adjuvants, Carrier 42%.

[0036] Among them, the auxiliary agent contains 9% of dispersant and 6% of emulsifier, the dispersant is naphthalene sulfonate, the emulsifier is anionic surfactant K-12; the carrier is white black carbon and kaolin.

[0037] The preparation method of the compound herbicide of the present embodiment comprises: absorbing high-efficiency haloxyfop-methyl with white carbon black and then mixing with trifluxysulfuron-methyl, pyrizachlor, quizalofop-p-ethyl, naphthalenesulfonate, K-12, After the kaolin is mixed evenly, it is jet-milled to obtain 43% wettable powder.

[0038]

Embodiment 3

[0040] A compound herbicide comprising the following components by mass fraction: 8% trifluxysulfuron-methyl, 12% pyriflux-methyl, 17% quizalofop-p-ethyl, 18% beta-halofop-pyl, 12% adjuvants, Carrier 33%.

[0041] Among them, the auxiliary agent contains 6% dispersant and 2% emulsifier, the dispersant is naphthalene sulfonate, the emulsifier is anionic surfactant K-12; the carrier is white black carbon and diatomaceous earth.

[0042] The preparation method of the compound herbicide in this example comprises: after absorbing high-efficiency haloxyfop-methyl with white carbon black, mixing it with trifluxysulfuron-methyl, pyriflux-methyl, quizalofop-p-ethyl, K-12 and diatomaceous earth, Then it is crushed by airflow, and then granulated to obtain 55% dispersible granules.

Abstract

The invention discloses a composite herbicide, which comprises the following components in percentage by mass: 0.5 to 30 percent of trifloxysulfuron, 0.5 to 30 percent of pyrithiobac-sodium, 3 to 20 percent of quizalofop-p-ethyl, 3 to 20 percent of haloxyfop-p-methyl, 5 to 20 percent of auxiliaries, and 5 to 80 percent of solvent and / or carrier. A preparation method of the composite herbicide comprises the following steps: adsorbing the efficient haloxyfop-p-methyl with white black carbon; mixing absorbed haloxyfop-p-methyl with trifloxysulfuron, pyrithiobac-sodium, quizalofop-p-ethyl, the auxiliaries and the carrier; and crushing by virtue of airflow to obtain a wettable powder product. The composite herbicide has the beneficial effects that: a weed killing spectrum is enlarged, the weedkilling effect is improved, and the safety to cotton and afterreap crops is good.

Description

[0001] technical field [0002] The invention relates to a herbicide, in particular to a composite herbicide containing various organic compounds and a preparation method thereof. [0003] Background technique [0004] Cotton is one of the main economic crops in my country, and effective prevention and control of weeds in cotton fields is one of the main methods to increase cotton production. For the main weeds in cotton fields: purslane, iron amaranth, retroverted amaranthus, etc., pendimethalin, acetochlor, trifluralin, etc. are mainly used for control at present. They mainly control gramineous weeds and some broad-leaved weeds, and the resistance of weeds is getting stronger and stronger, but the control effect on weeds such as purslane, iron amaranth, and retroverted amaranth is very poor. From this point of view, the main weeds in cotton fields are broad-leaved weeds, and most of the control of weeds in cotton fields currently uses gramineous herbicides, and no herbic...
