Abstract[English]
A pyriproxyfen microcapsule suspension, wherein raw materials for preparing the pyriproxyfen microcapsule suspension comprise, in percentage by weight: 8%-12% of pyriproxyfen, 1%-3% of isocyanate, 0.1%-0.5% of polyamines, wherein deionized water is used to make the suspension up to 100%. Compared with traditional dosage forms, the pyriproxyfen microcapsule suspension can significantly reduce the toxicity to hydrobionts, and can greatly reduce the dosage used in the field, thereby effectively reducing environmental pollution and pesticide residues, and lowering production and usage costs. The dosage form of the microcapsule suspension conforms to the future development trend of agricultural environmental protection, and can reduce odor, improve efficacy, and prolong the duration of effectiveness.[French]
Suspension de microcapsules de pyriproxyfène, des matières premières destinées à préparer la suspension de microcapsules de pyriproxyfène comprenant, en pourcentage en poids : de 8 % à 12 % de pyriproxyfène, de 1 % à 3 % d'isocyanate, de 0,1 % à 0,5 % de polyamines, de l'eau désionisée étant utilisée pour que le pourcentage en poids de la suspension soit de 100 %. Comparativement à des formes pharmaceutiques classiques, la suspension de microcapsules de pyriproxyfène peut considérablement réduire la toxicité vis-à-vis des biotes aquatiques, et peut considérablement réduire le dosage utilisé dans le domaine, ce qui permet d'efficacement réduire la pollution environnementale et les résidus de pesticides, et de réduire les coûts de production et d'utilisation. La forme pharmaceutique de la suspension de microcapsules est conforme à la future tendance au développement de la protection de l'environnement agricole, et peut réduire l'odeur, améliorer l'efficacité et prolonger la durée d'efficacité.[Chinese]
一种吡丙醚微囊悬浮剂，所述吡丙醚微囊悬浮剂的制备原料以重量百分比计包括：吡丙醚8-12%，异氰酸酯1-3%，多元胺0.1-0.5%，去离子水补充至100%。与传统剂型相比，吡丙醚微囊悬浮剂可明显降低水生生物毒性；并且可以大幅减少田间用药量，有效减少环境污染和农药残留，降低生产和使用成本；该微囊悬浮剂剂型符合未来农业环保化发展的趋势；可减轻气味，提高药效，延长持效期。
