Abstract
Okra is the most important vegetable crop of the tropical and subtropical regions of the world. To investigate on efficient management of Tetranychus urticae Koch infesting okra, synthetic, botanical and microbial pesticides were used in a study established in 2021 and 2022. The crop was treated with propargite (57 EC), clofentazine (50 SC), cyflumetofen (20 SC), fenpyroximate (5 EC), dicofol (18.5% EC), azadirachtin (0.03%), NSKE (5%), neem oil (98%, Paeciomyces fumosoroseus (EC) and Paeciomyces fumosoroseus (dust). The data evaluate the efficacy of pretreatment, 1, 3, 7 and 14th day after treatment. Overall clofentazine (89.96%) was found effective to control mite population followed by cyflumetofen (81.04%), fenpyroximate (77.56%), propargite (73.96%), dicofol (71.87%) in synthetic group. In botanical and microbial pesticides NSKE (52.32%) was found effective followed by azadirachtin (46.52%), neem oil (37.96%), Paeciomyces fumosoroseus 1x109 dust (31.47%) and Paeciomyces fumosoroseus 1x109 EC (27.95%), respectively. All the treatments are shows significant difference at five per cent probability level. Thus farmers can use such pesticides to reduce mite population in okra fields.
