Embodiment 1

[0033] The oil suspension concentrate containing oxadiazone and fomesafen of the present embodiment has the following components and weight content:

[0034] Oxadiazone 25%

[0035] Fomesafen 30%

[0036] Surfactant 10%

[0037] Other functional additives 5%

[0038] Oil 30%

[0039] The surfactant in this embodiment is a mixture of dispersant and wetting agent. The dispersant is calcium lignosulfonate, with a content of 8%; the wetting agent is sodium lauryl sulfate, with a content of 2%; other functional additives are thickener xanthan gum.

Embodiment 2

[0041] The difference between this embodiment and embodiment 1 is: its component and weight content are:

[0042] Oxadiazone 25%

[0043] Fomesafen 4%

[0044] Surfactant 11%

[0045] Other functional additives 5%

[0046] Oil 55%

[0047] The surfactant in this embodiment is a mixture of dispersant and wetting agent. The dispersant is alkylnaphthalene sulfonate formaldehyde condensate, with a content of 8%; the wetting agent is sodium lauryl sulfate, with a content of 3%; other functional additives are thickener xanthan gum.

Embodiment 3

[0049] The difference between this embodiment and embodiment 1 is: its component and weight content are:

[0050] Oxadiazone 15%

[0051] Fomesafen 25%

[0052] Surfactant 15%

[0053] Other functional additives 5%

[0054]Oil 40%

[0055] The surfactant of this embodiment is the mixing of dispersant and emulsifier. The dispersant is polycarboxylate, with a content of 8%; the emulsifier is Nongru BY-125, with a content of 7%; other functional additives are thickener organic bentonite.

Abstract

The invention belongs to the field of pesticides and herbicides, and in particular relates to oil miscible flowable concentrate containing oxadiazon and fomesafen. The oil miscible flowable concentrate contains the following ingredients in content by weight: 1-40 percent of oxadiazon, 1-50 percent of fomesafen, 5-20 percent of surfactant, 1-10 percent of other functional auxiliary ingredient, and 10-80 percent of oil; and the total weight content of all the ingredients is 100 percent. The composition is mainly used for controlling annual broadleaf weeds and gramineous weeds in soybean, peanut and garlic fields. The composition has the characteristics of synergistic effect, expansion in herbicidal spectrum, delay in herbicide resistance and low cost.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to an oil suspension containing oxadiazone and fomesafen. Background technique [0002] Oxadiazon is a heterocyclic selective pre-emergence and post-emergence herbicide. It is mainly absorbed through weed buds or stems and leaves. The effect on weeds in the germination stage is the best, and the effect decreases as the weeds grow up, and it is basically ineffective on adult weeds. Apply 180-270g / ha (active ingredients) before or after emergence to rice, soybean fields, vineyards, stone fruit orchards, etc., to control gramineous and broad-leaved weeds in dry and paddy fields, especially barnyardgrass and crabgrass , Setariae, Qianjinzi, Porcini, Purslane, Echinacea, Chenopodiaceae and Euphorbiaceae weeds. The agent has the following characteristics: wide herbicidal spectrum; can control malignant weeds; long efficacy period in soil; stable efficacy; can be mixed with ot...
