Field trials of various neem formulations were conducted to determine their effectiveness for the control of some major pests of eggplant, Solanum melogena (L), okra, Hibiscus esculentus (L) and cowpea, Vigna unguiculata (L), Walp. Various concentrations of neem emulsion reduced incidence of Selepa docilis (Butler), Urentius sp. and Zonocerus variegatus (L), on eggplant. Damage caused by Sylepta derogata (F), defoliator of okra, was less in plots treated with 5, 10 and 20% aqueous-methanol extracts of defatted neem cake. Moreover, neem seed cake applied as dust enhanced cowpea yield.
