Evaluation of Insecticides, SAR Chemicals and Essential Oils for the Management of Bean Common Mosaic Virus (BCMV) in French Bean (Phaseolus vulgaris L.)

Abstract

A field experiment was conducted to evaluate the effectiveness of different insecticides, SAR chemicals, and essential oils in the management of Bean Common Mosaic Virus (BCMV) in French bean during Rabi 2024-25 at Department of Plant Pathology, College of Agriculture, Latur. Treatments included Cyantraniliprole, Imidacloprid, Thiamethoxam, Buprofezin, Diafenthiuron, Karanj oil, Neem oil, and Salicylic acid, along with an untreated control using a Randomized Block Design (RBD) with three replications. In a field assay, results indicated that among the treatments Cyantraniliprole 10.26% OD was the most effective treatment, recording the lowest mean aphid population (8.38 aphids/3 leaves) and minimum mean BCMV incidence (14.80%). Consequently, it produced the highest grain yield (14.36 q/ha) and additional income over control (Rs. 31,850/ha), followed by T1 (Imidacloprid) recorded 10.32 aphid/3 leaves with disease incidence 15.86 % and T2 (Thiamethoxam) recorded 12.96 aphid/3 leaves with disease incidence 17.32 %. While T6 (Karanj oil) recorded highest aphid population 20.86 aphid/3 leaves with highest disease incidence 24.92 %. Significantly highest percent disease inhibition was achieved with the insecticide Cyantraniliprole (43.70%) followed by Imidacloprid (39.67 %) and Thiamethoxam (34.13 %). While Karanj oil recorded least percent disease inhibition (05.19 %). T3 Cyantraniliprole recorded significantly highest grain yield (14.36 q/ha) followed by T1 Imidacloprid (yield 13.98 q/ha) and T2 Thiamethoxam (yield 13.59 q/ha). While T6 Karanj oil recorded lowest grain yield (10.33 q/ha). Based on the additional income over control the most profitable treatment which recorded (31,850 Rs/ha) was spraying of Cyantraniliprole. This was followed by spraying with Imidacloprid (29,380 Rs/ha) and Thiamethoxam (26,845 Rs/ha). However minimum profit was found with Karanj oil (5,655 Rs/ha). The insecticides treatment i.e. spraying of Cyantraniliprole, Imidacloprid and Thiamethoxam were the best insecticides against aphids and for bean common mosaic virus management.
