Field Efficacy of Botanicals against Sucking Pests in Pigeonpea [Cajanus cajan (L.) Millsp.] under Organic Cultivation

Investigations were carried out at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, S. D. Agricultural University, Sardarkrushinagar during kharif, 2022-23 and 2023-24 for evaluation of various botanicals on the incidence of sucking pests viz., aphid, thrips, leaf hopper and pod bug in pigeonpea. Among the botanicals treatment, NSKE @ 5 per cent + cow urine @ 10 per cent recorded significantly minimum 1.91 aphid per 10 cm shoot, 3.54 thrips per flower, 2.27 leaf hopper per 3 leaves and 1.93 pod bug per plant. The highest yield was obtained in the treatment of NSKE @ 5 per cent + cow urine @ 10 per cent (1300 kg/ha) and it was at par with NSKE @ 5 per cent (1282 kg/ha) and dashparniark @ 10 per cent (1258 kg/ha). The maximum increase in yield over control (76.07%) was obtained in NSKE @ 5 per cent + cow urine @ 10 per cent. The minimum avoidable losses (1.41%) and highest PCBR (1:16.12) was observed in the plot treated with NSKE @ 5 per cent.
