Fluridone and oxyfluorfen contained weedicidal composition

Abstract

The invention discloses a fluridone and oxyfluorfen contained weedicidal composition and the application thereof. The fluridone and oxyfluorfen contained weedicidal composition comprises fluridone asa first active component, oxyfluorfen as a second active component and an auxiliary agent, wherein the weight ratio of the first active component to the second active component is 1:20 to 20:1, preferably 1:10 to 10:1. The fluridone and oxyfluorfen contained weedicidal composition can be prepared into missible oil, an aqueous emulsion, a suspension, a microcapsule suspension, water-dispersible granules and a dispersible oil suspension which are agriculturally acceptable. The fluridone and oxyfluorfen contained weedicidal composition is reasonable in components, good in weedicidal effect and low in using cost; the activity and the weedicidal effect of the fluridone and oxyfluorfen contained weedicidal composition are not simple superposition of the activities of the components; compared with the existing single agent, the fluridone and oxyfluorfen contained weedicidal composition has the advantages of an obvious weedicidal synergistic effect, low dosage and high crop safety; the fluridone and oxyfluorfen contained weedicidal composition has a very good control effect on grassy weeds such as digitaria sanguinalis, eleusine indica, barnyard grass, green bristlegrass, wild oat grass, bromegrass and bluegrass, and broad-leaved weeds such as glaucum, solanum nigrum, amaranthus retroflexus, purslane, convolvulus arvensis, persicaria lapathifolia, abutilon theophrasti, cocklebur, dayflower, sisymbrium sophia and capsella bursa-pastoris.

Description

technical field [0001] The present invention relates to a herbicidal composition containing fluoridoxazone and oxyfluorfen, which is composed of the first active ingredient fluoridoxyfen, the second active ingredient oxyfluorfen and adjuvants, and belongs to compound pesticide technology field. Background technique [0002] Fluridone, English name fluridone, chemical name: 1-methyl-3-phenyl-5-(α,α,α-trifluoro-m-tolyl)-4-pyridone. Fluoxetalone is a pyrrolidone herbicide, which can be used in wheat, rice, corn, cotton, pasture and non-cultivated land, etc., to control most weeds in water or water surface, and can also be used as a pre-emergent selective herbicide to control Annual grass weeds, broad-leaved weeds and some perennial weeds, also suitable for some weeds resistant to glyphosate. [0003] Ethoxyfluorfen, English name oxyfluorfen, chemical name: 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene. Oxyflufen is a contact herbicide that works in the pres...
