Embodiment 1

[0020] Biological Assay Example 1: Combined Effect Assay.

[0021] In order to further understand the combined effect of the combination of thifensulfuron-methyl and acesulfame on weeds, the inventors conducted a formula screening test on the mixture of thifensulfuron-methyl and acesulfame:

[0022] experiment material:

[0023] [Galium aparine L.Var.tenerum] (seeds collected in the field).

[0024] See Alopecurus aequalis Sobol [Alopecurus aequalis Sobol] (seeds collected in field).

[0025] Test Instruments:

[0026] Controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0027] experiment method:

[0028] First weigh a certain quality of 95% thifensulfuron-methyl original drug and 96.5% acesulfame original drug, add acetone to fully dissolve, dilute with 0.1% Tween 80 aqueous solution, and prepare single-dose mother solutions respectively, according to the mixing The purpose is to set a ser...

Embodiment 1

[0039] Formulation Example 1: (30% Thifensulfuron-Acesulfame wettable powder).

[0040]

[0041] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized and then mixed to obtain 30% thifensulfuron-apesullam wettable powder.

[0042] Formulation Example 2: (15% Thifensulfuron-Acesulfame dispersible oil suspension).

[0043]

[0044] Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase; mix under high-speed stirring to prepare 15% thifensulfuron-apesullam dispersible oil suspension concentrate.

[0045] Formulation Example 3: (33% Thifensulfuron-Acesulfame Suspending Concentrate).

[0046]

[0047]

[0048] The above formula was pre-crushed according to the proportion, then added to a sand mill for grinding, and then mixed by high shear to prepare a 33% thifensulfuron- acesulfame suspending agent.

[0049] Formulation Example 4: (35% Thifensulfuron-Acesulfame wat...

Abstract

The invention discloses herbicidecomposition containing thifensulfuron-methyl and pyroxsulam. The herbicidecomposition comprises effective components, namely, the thifensulfuron-methyl and the pyroxsulam, and the rest is pesticide additives; the mass part ratio of the thifensulfuron-methyl to the pyroxsulam is in a range of 1:5-5:1, and the total mass of the thifensulfuron-methyl and the pyroxsulamaccounts for 3%-80% of the mass of the herbicidecomposition. According to application requirements, the herbicidecomposition can be prepared into one of a dispersible oil suspending agent, a suspending agent, wettable powder and water dispersible granules and is used for preventing and killing offannual grass and broadleaf weeds in winter wheat fields. The composition is obviously superior to various single agents in prevention and killing off effects on the annual grass and broadleaf weeds in the winter wheat fields, the dosage is reduced, and the drug resistance of the weeds is delayed.

Description

technical field [0001] The invention relates to a composition containing thifensulfuron-methyl and acesulfame, which is used as active ingredients to prevent and control annual gramineous and broad-leaved weeds in winter wheat fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all will show some defects and limitation. Mixing different types of herbicides has the advantages of broad herbicidal spectrum, improving the actual effect, delaying weed resistance, saving time and labor, etc. [0003] Thifensulfuron-methyl is a systemic conduction type post-emergence selective herbicide. It is a branched-chain amino ...
