Stability studies on newly developed botanical formulation: Polymin 40 EC

Abstract

Use of botanicals in plant disease management is getting popular nowadays due its merits over the environment and agricultural products. An ecofriendly botanical formulation “Polymin 40 EC” was developed from the chloroform extract of Polygonum minus Huds which possessed broad spectrum antimicrobial activity against plant pathogens. The stability in addition to its activity is more important for a plant protection chemical and hence the stability of the newly developed botanical formulation “Polymin 40 EC”was studied in detail. The emulsion stability and thermostability analysis revealed that “Polymin 40 EC” was found to be more stable and 2% “Polymin 40 EC” was found to have a neutral pH. The formulations were also found to retain their antimicrobial activity upto a period of three months.
