Efficacy of Phytochemicals Against the Sucking Pests of Okra Abelmoschus esculents (L) Moench

The field experiments conducted during 2005-06 at PAJANCOA & RI, Karaikal with Arka anamika okra variety to study the efficacy of botanicals on the sucking pests with ten treatments in three replications. In the first crop the population of aphid was less in NSKE 5 per cent (2.59), neem oil 3 per cent (3.33) and notchi leaf 5 per cent (4.53). Jassid and whitefly population was less in neem oil 3 per cent ( 0.25 and 0.38). Similar trend was also noticed in the second crop. The maximum yield was recorded in NSKE 5 percent (9892.12, 9325.72 kg ha^-1) as against in control (5800.00 and 5916. 67 kg ha^-1) in the first and second crop, respectively. Among the botanicals the NSKE registered highest B:C ratio of 2.28 and 2.15 in the first and second crop, respectively.
