Comparative efficacy of seed treatment and their combinations with foliar spray of insecticides for the management of Antigastra catalaunalis in sesame

AK Panday, Rajani Bisen, Roshni Sahu and ARG Ranganatha

An experiment was conducted at research farm of Project Co-ordinating Unit Sesame and Niger, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, India during kharif season of 2013 and 2014 to evaluate the efficacy of insecticides viz., imidacloprid, chlorpyriphos and thiamethoxam as a seed treatments and their combinations with foliar spray of profenofos 50 EC and NSKE 5% for the management of leaf roller and capsule borer (Antigastra catalaunalis) in sesame crop. Experimental results indicated that at initial stage of the plant growth all the plots having treated seed had significant impact on percent plant damage and decrease in larval population over the control. Pre foliar spray count of larval population showed that, seed treatment alone reduced the larval population from 22.81% to 33.33% and plant damage from 56.90% to 76.28% over the control. In post foliar spray observations, superiority of treatment T4 (seed treatment with imidacloprid + foliar spray of profenofos) was significantly envisaged with record of lowest larval population (0.15/larvae plant), flower (0.96%) and capsule damage (1.44%) in comparison to other treatments and registered a mean reduction of 93.03% in larval population, 93.34% in flower infestation and 90.59% in capsule damage over control. Similarly the results of seed yield showed that, out of ten treatments, all the six treatment combinations (seed treatment + foliar spraying of insecticides) gave higher seed yield as compared to control plot and the plots received seed treatment alone. Among these mentioned treatment combinations, treatment T4 (seed treatment with imidacloprid + foliar spray of profenofos 50 EC) out performed over others in terms of percent increase in yield (95.00%) over control, however, treatment T6 (seed treatment with thiamethoxam 25 WG + foliar spray of profenofos 50 EC) was found the next best treatment in reducing the larval population, percent flower and capsule damage and enhanced seed yield.
