A study carried out two consecutive Rabi seasons at Agronomy Farm, College of Agriculture, Swami Keshwanad Rajasthan Agricultural University, Bikaner, aimed to evaluate the field efficacy of treatment combinations against termites and assess the economies aspects of various treatments. The experiment was laid out in simple randomized block design with nine treatments replicated thrice. The treatments comprised seed treatments and soil applications of different insecticides, including Imidacloprid 600 FS, Clothianidin 50 WDG, Fipronil 5 SC, Beauveria bassiana 1.15 WP, and Metarhizium anisopliae 1.15 WP, as well as their combinations. The results showed that using Imidacloprid 600 FS at 5 ml/kg seeds and Beauveria bassiana 1.15 WP on the soil at a rate of 2 kg/ha consistently led to the lowest total and percentage avoidable losses, as well as the highest increase and percentage yield compared to the untreated control. Economic analysis revealed varying levels of net returns and benefit-cost ratios across treatments. Plots treated with Fipronil 5 SC at 5 ml/kg had the best benefit-cost ratio, followed by plots treated with Fipronil 5 SC plus Metarhizium anisopliae 1.15 WP at 2 kg/ha. These findings provide valuable insights into the management of termite-induced losses in chickpea cultivation, as well as feasible treatment strategies for farmers to improve crop yield and profitability.
