Embodiment 1

[0023] Weigh 5% chlorpyridone, 20% promethazine, 6% Nongru 500#, 2% Nongru 1601#, 4% Nongru 400#, 5% ethyl acetate, and add biodiesel to 100% by weight . The above-mentioned raw materials were mixed, stirred and dissolved completely to obtain 25% chlorpyrazone·promethonin emulsifiable concentrate.

Embodiment 2

[0025] Weigh 10% chlorpyridone, 15% promethazine, 4% Nongru 700#, 3% TX-10, 6% Nongru 1601#, 8% cyclohexanone, and add xylene to 100% by weight. The above-mentioned raw materials were mixed, stirred and dissolved completely to obtain 25% chlorpyrazone·promethonin emulsifiable concentrate.

Embodiment 3

[0027] Weigh 25% chlorpyridone, 10% promethazine, 6% Tween-60#, 4% cyclohexanone, 1 epichlorohydrin, 3% glycerin, 4% polyvinyl alcohol, 0.5% formaldehyde, 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 35% chlorpyrizone·proteron water purifying emulsion.

Abstract

The invention discloses a herbicidal composition containing fluridone and prometryn and application thereof. The herbicidal composition is composed of the first active ingredient isofluridone, the second active ingredient prometryn 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 echinochloa crusgalli, setaria viridis, digitaria sanguinalis, eleusine indica,avena fatua, bromus japonicus and poa annua and broadleaf weeds such as portulaca oleracea, convolvulus arvensis, persicaria lapathifolia, abutilon theophrasti medicus, chenopodium glaucum, nightshade, amaranthus retroflexus, xanthium sibiricum, commelina communis, descurainia sophia and capsella bursa-pastoris.

Description

technical field [0001] The invention relates to a herbicidal composition containing chlorpyridone and proturon, which is composed of a first active component, chlorpyridone, a second active component, profenazin, and an auxiliary agent, 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] Promethazine, the English name is prometryn, the chemical name is: 4,6-bisisopropylamino-2-methylthio-1,3,5-triazine. Selective systemic conduction herbicide, which can be absorb...
