Embodiment 1

[0105] Embodiment 1: wettable powder

[0106] Saflufenacil 10% Bromoxynil 50% Sodium butyl naphthalene sulfonate 3% Sodium methylene dinaphthalene sulfonate 3% Silica 20% Kaolin margin

[0107] 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 herbicidal composition.

Embodiment 2

[0108] Embodiment 2: suspoemulsion

[0109] Saflufenacil 5% Bromoxynil 30% 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

[0110] Bromoxynil octanoyl was dissolved in N-methylpyrrolidone, and sodium p-methoxy fatty amidobenzenesulfonate was added to obtain an oil phase; saflufenacil, p-methoxy fatty amidobenzenesulfonic acid Sodium, alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, and water are ground and / or high-speed sheared to obtain a saflufenacil water suspension; add the oil phase to the water phase under stirring to obtain a suspoemulsion.

Embodiment 3

[0111] Embodiment 3: water dispersible granules

[0112] Saflufenacil 40% Bromoxynil 40% Sodium dodecyl sulfate 3% polycarboxylate 3% ammonium sulfate 4% polyethylene glycol 2% Kaolin margin

[0113] Dry crushing, granulation, drying and sieving of the above formula in proportion to prepare water-dispersible granules of the herbicidal composition.

Abstract

The invention relates to a weeding composition, in particular to a binary compound weeding composition applied to crop fields. The invention relates to a weeding composition which contains active components of saflufenacil and fluoroglycofen-ethyl, and the weight ratio of saflufenacil to bromoxynil and a derivative thereof is 1:1 to 1:50. The invention further relates to application of the weeding composition in preventing and killing off unexpected plants of broadleaf weeds, cyperaceous weeds and gramineous weeds. The weeding composition produces the effect of synergistic interaction when the broadleaf weeds, cyperaceous weeds and gramineous weeds are prevented and killed off.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a binary compound herbicidal composition applied to crop fields. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, the performance of current crop protection products is continuously improved to meet the requirements of high efficiency, low toxicity and no pollution. [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 herbicidal activities. When the potency of a mixture of two or more active ingredients is greater than ...
