Application of Neem and Karanjia Oils as Natural Pesticide Microemulsion Systems

Einsatz von Neembaumölen und Karanjiaölen als natürliche Pestizid-Mikroemulsionen
  • S. Ghosh , D. N. Bhowmick and A. P. Pratap

Abstract

Microemulsions are preferred over conventionally used pesticide systems for their long term thermodynamic stability, low viscosity, cost economy and aesthetic appeal. Such systems provide a method for preparing an isotropic mixture of oil and water. Neem and Karanjia isolates have proven activities. Therefore, uses of these oils provide a biologically and environmentally acceptable pesticide formulation. The present investigation deals with the systematic study to arrive at the economical composition for formulating microemulsion systems using these oils. These microemulsions, when diluted with water, formed macroemulsions which were stable over an extended period of time.

Kurzfassung

Gegenüber konventionellen Pestizidsystemen sind Mikroemulsionen wegen ihrer langzeitigen thermodynamischen Stabilität, geringen Viskosität, Wirtschaftlichkeit und ästethischen Erscheinung bevorzugt. Solche Systeme bieten sich für die Herstellung von isotropen Mischungen aus Öl und Wasser an. Neembaum- und Karanjia-Absonderungen haben nachgewiesene Aktivitäten. Daher sollte man mit diesen Ölen biologisch akzeptable und umweltfreundliche Pestizid-Formulierungen erhalten. In diesem Vorhaben sollen durch systematische Studien wirtschaftliche Zusammensetzungen für die Formulierungen von Mikroemulsionen aus diesen Ölen gefunden werden. Derartige Mikroemulsionen bilden bei Verdünnung mit Wasser Makroemulsionen, die über eine lange Zeit stabil sind.
