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...
