Embodiment 1

[0023] Weigh 10% chlorpyrazone, 20% oxadiazone, 4% Nongru 2201, 2% TX-10, 5% Span-60#, 5% ethyl acetate, and add toluene to 100% by weight. The above-mentioned raw materials were mixed, stirred and dissolved completely to obtain 30% chlorpyrazone-oxadiazone EC.

Embodiment 2

[0025] Weigh 25% chlorpyridone, 10% oxadiazone, 4% Nongru 500#, 2% Nongru 600#, 4% Nongru 1601#, 6% dimethylformamide, add xylene to 100% parts by weight. The above-mentioned raw materials were mixed, stirred and dissolved completely to obtain 35% chlorpyrazone-oxadiazone EC.

Embodiment 3

[0027] Weigh 20% chlorpyridone, 5% oxadiazone, 6% Tween-60#, 4% toluene, 2% epichlorohydrin, 2% glycerin, 4% polyvinyl alcohol, 0.6% sodium benzoate, remove Ionized water was added to 100% by weight. The above raw materials were mixed evenly and stirred at a high speed to prepare a 25% chlorpyrazone-oxadiazone aqueous emulsion.

Abstract

The invention discloses a herbicidal composition containing fluridone and oxadiazon and application thereof. The herbicidal composition is composed of the first active ingredient isofluridone, the second active ingredient oxadiazon and an auxiliary agent, and the weight ratio of the first active ingredient to the second active ingredient is from 1:20 to 20:1, preferably from 1:10 to 10:1. The composition can be prepared into agriculturally-acceptable emulsifiable concentrates, aqueous emulsions, suspension agents, microcapsule suspension agents, water-dispersible granules and dispersible oil suspension agents. The composition is composed of reasonable components and is good in herbicidal effect and low in pesticide cost, and the activity and herbicidal effect of the composition are not simple superposition of the activity of all the components; compared with an existing single agent, the composition has the advantages that the herbicidal synergistic effect is obvious, the dosage is low, and the safety of crops is good. The composition has good prevention and treatment effects on gramineous weeds such as avena fatua, bromus japonicus, poa annua, echinochloa crusgalli, setaria viridis, digitaria sanguinalis and eleusine indica and broadleaf weeds such as xanthium sibiricum, commelina communis, descurainia sophia, capsella bursa-pastoris, portulaca oleracea, convolvulus arvensis,polygonum lapathifolium, abutilon theophrasti, chenopodium glaucum, nightshade and amaranthus retroflexus.

Description

technical field [0001] The invention relates to a herbicidal composition containing chlorpyrazone and oxadiazone, which is composed of a first active component chlorpyrazone, a second active component oxadiazone and adjuvants, and belongs to the technical field of compound pesticides. 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] Oxadiazon, the English name is oxadiazon, the chemical name is: 5-tert-butyl-3-(2,4-dichloro-5-isopropoxyphenyl)-1,3,4-oxadiazole-2( 3H)-ketone. Selective pre-emergence and post-emergence...
