Embodiment 1

[0100] Embodiment 1: wettable powder

[0101] Saflufenacil 25% Bensulfuron-methyl 25% Sodium butyl naphthalene sulfonate 3% Sodium methylene dinaphthalene sulfonate 3% Silica 20% Kaolin margin

[0102] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain the wettable powder of the herbicide composition.

Embodiment 2

[0103]Embodiment 2: suspoemulsion

[0104] Saflufenacil 50% Bensulfuron-methyl 1% Ethoxylated castor oil 5% N-Methylpyrrolidone 5% Sodium p-methoxy fatty amidobenzenesulfonate 8% Alkylphenol polyoxyethylene ether formaldehyde condensate sulfate 4% Magnesium Aluminum Silicate 1% Bentonite 1% Silicone 0.1% Glycerol 5% ionized water margin

[0105] Dissolve bensulfuron-methyl in N-methylpyrrolidone, add sodium p-methoxy fatty amidobenzenesulfonate to obtain an oil phase; mix saflufenacil, sodium p-methoxy fatty amidobenzenesulfonate , alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, and water are ground and / or high-speed sheared to obtain saflufenacil water suspension; add the oil phase to the water phase under stirring to obtain a suspoemulsion.

Embodiment 3

[0106] Embodiment 3: water dispersible granules

[0107] Saflufenacil 40% Bensulfuron-methyl 40% Sodium dodecyl sulfate 3% polycarboxylate 3% ammonium sulfate 4% polyethylene glycol 2% Kaolin margin

Abstract

The invention relates to a compounded herbicide composition and particularly relates to the binary-compounded compounded herbicide composition applied to crop fields. The compounded herbicide composition disclosed by the invention contains active ingredients, i.e., saflufenacil and bensulfuron-methyl, wherein a weight ratio of the saflufenacil to the bensulfuron-methyl is (50: 1) to (1: 50). The invention further relates to an application of the compounded herbicide composition in control of undesired plants, i.e., broad-leaved weeds, cyperaceous weeds and Gramineae weeds. The compounded herbicide composition disclosed by the invention generates a synergy effect during control of the Gramineae weeds, broad-leaved weeds and cyperaceous weeds of the fields.

Description

[0001] This application is a divisional application with the application number 201510200642.0, the application date is April 24, 2015, and the invention name is "Compound Herbicide Composition". technical field [0002] The invention relates to a compound herbicide composition, in particular to a binary compound compound herbicide composition applied in crop fields. Background technique [0003] In crop farming, it is important to control weeds that inhibit the growth of crops and cause a decrease in yield and to protect crops. Some herbicidal active ingredients that can effectively control weeds and are safe to crops have been developed, greatly reducing the losses caused by weeds in crop cultivation. Herbicides used to control weeds in specific crop cultivation must not only have high herbicidal activity and a wide herbicidal spectrum, but also be sufficiently safe for the environment and crops. However, not all herbicides can fully meet the above requirements. [0004]...
