Methods for decontamination of Sweet Flag Emulsifiable Concentrate (SFEC) formulation from maize and green gram seeds

Abstract

Investigation were conducted to develop decontamination techniques for Sweet Flag, (Acorus calamus L.) EC formulation on rice weevil, Sitophilus oryzae (L.) and pulse beetle, Callosobruchus maculatus (F.) on maize and green gram seeds in storage during 2016-2017 at the Department of Agricultural Entomology, Agricultural College and Research Institute, Coimbatore. In the study to evaluate the decontamination techniques for sweet flag EC (SFEC) in terms of insecticidal action on C. maculatus in green gram seeds and S. oryzae in maize seeds, lowest mortality of C. maculatus (46.60%) and S. oryzae (1.10%) was observed in decontamination with lime solution 5 per cent while 100.00 and 72.2 per cent was observed in sweet flag EC without decontamination which indicated that lime solution might have removed the sweet flag EC formulation from the green gram and maize seeds.
