Means followed by the same letters in a column are not significantly different at LSD () T1 = sesame at 40% as seed coating for 30 min prior to sowing; T2 = sesame at 40% as drenching two weeks after germination; T3 = neem at 50% as seed coating for 30 min prior to sowing; T4 = neem at 50% as drenching two weeks after germination; T5 = citrus at 100% as seed coating for 30 min prior to sowing; T6 = citrus at 100% as drenching two weeks after germination; T7 = velum (check) at 3.8 ml/1L as seed coating for 30 min prior to sowing; T8 = velum (check) at 9.8 ml/15L of water as drenching two weeks after germination; T9 = control (no application).
