Abstract

Emulsifiable Concentrate (EC) formulations have been criticized due to presence of large amount of solvents. In present work, user and environment friendly Chlorpyriphos 20 EC was developed using biodegradable vegetable oil to replace high-risk volatile solvents. Physico-chemical parameters of developed ECs were tested to standardize the formulations. Experimental results showed that soybean oil and combination of Nonyl Phenol Ethoxylate-13 and Calcium Alkyl Benzene Sulfonate was the best formulation. Storage stability of vegetable oil based EC formulation was higher than the organic solvent based. Developed ECs were undergone in-vivo bioassay to investigate their effectiveness against brinjal fruit and shoot borer during 2013-2014 and 2014-2015. Vegetable oil based EC was found to superior over solvent based EC formulations. Vegetable oil based EC was relatively soft to prevailing natural defenders and exhibits no phytotoxicity.
