Embodiment 1

[0033] The emulsifiable 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] Solvent 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; the solvent is N,N-dimethyl Formamide and isopropylamine, of which N,N-dimethylformamide content is 15%.

[0040] The production method of the emulsifiable concentrate containing oxadiazone and fomesafen in this embodiment is as follows: the active ingredients oxadiazone and fomesafen are added to the solvent, and surfactants and other functional additives are added therein. Stir in the mixing tank to mix evenly.

Embodiment 2

[0042] The difference between this embodiment and embodiment 1 is: its component and weight content are:

Abstract

The invention belongs to the field of pesticide herbicides, and particularly relates to missible oil containing oxadiazon and fomesafen. The missible oil comprises the following components by weight: 1%-40% of oxadiazon; 1%-50% of fomesafen; 5%-20% of a surfactant; 0%-10% of other functional additives; and 10%-80% of solvents, wherein the sum of the weight percents of the components is 100%; the composition is mainly used for controlling annual broad leaf weeds and gramineous weeds for soybean land, peanut land, and garlic land. The composition has the characteristics of synergy, expansion of herbicide controlling spectra, delay of resistance to drugs, and low cost.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to an emulsifiable concentrate containing oxadiazone and fomesafen and a production method thereof. 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 s...
