Physico-Chemical Characterization and Synthesis of Potassium Laurate as Herbicides against Moss
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 4
Abstract
The present study was carried out during March 2009 to September 2012. Regular and periodical visit to different sites were made during this period. Mosses collected from different habitats such as mosses growing on humus-rich soil, on calcareous soil, on lateritic soil, on peaty soil, on forest floor. Growth forms also studies like mosses growing as mixed societies, in unmixed stands, on exposed rock, in moist mud and Aquatic mosses, Epiphytic mosses. Hence, it is synthesized by metathesis of potassium salt and fatty acid (lauric acid) and characterized by IR, pH and Conductometric studies. As potassium laurate are inherently non-toxic substances and disappear after the desired period of herbicides activity. It is also found that the effective concentration to remove the moss is at CMC and above CMC on weekly application. It is a contact herbicide. Since water has high surface tension, it tends to maintain its round droplet shape when sitting on the surface of leaf. The carboxylate acts to break down this surface tension of the droplet allowing the liquid to spread over leaf surface. This results in more of the pesticide coming into contact with the leaf and as a result more herbicides get into the plant and enhance its herbicidal action.
