Embodiment 1

[0099] Embodiment 1: wettable powder

[0100] Saflufenacil 25% Bensulfuron-methyl 25% Sodium butyl naphthalene sulfonate 3% Sodium methylene dinaphthalene sulfonate 3% Silica 20% Kaolin margin

[0101] 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

[0102] Embodiment 2: suspoemulsion

[0103] 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

[0104] 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

[0105] Embodiment 3: water dispersible granules

[0106] 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 compound herbicide composition, in particular to a binary compound herbicide composition applied to crop fields. The compound herbicide composition contains the active ingredients of saflufenacil and bensulfuron methyl, wherein the weight ratio of saflufenacil to bensulfuron methyl is 50:1-1:50. The invention further relates to application of the compound herbicide composition in controlling the undesirable plants of broadleaf weeds, cyperaceae weeds and gramineous weeds. The compound herbicide composition generates a synergistic effect when controlling gramineous weeds, broadleaf weeds and cyperaceae weeds in fields.

Description

technical field [0001] The invention relates to a compound herbicide composition, in particular to a binary compound compound herbicide composition applied in crop fields. Background technique [0002] 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. [0003] The most common method for increasing herbicidal activity and broadening the herbicidal spectrum of existing herbicides is to mix two or more herbicidally active substances with different herbicida...
