Abstract
Field experiment was conducted at the Michael Okpara University of Agriculture, Umudike, to evaluate the field performance of 5% aqueous and 5% petroleum ether extract of seeds of Monodora mysristica (Gaertn.) Dunal and Jatropha curcas L. for the control of flea beetle, Podagrica spp., on okra variety, NHAE 47-4. A synthetic pyrethoid, lamdacyhalothrin at 25g a.i/ha was incorporated in the study for comparison. The 5% petroleum ether extracts of the plant material and the lamdacyhalothrin significantly (P 5% MSPEE > 5% JSPEE > 5% MSAE > 5% JSAE > control. It was concluded that the plant extract showed good prospects for the control of Podagrica spp infestation on okra, especially the petroleum ether extracts. It is suggested that higher dosages, better formulations and closer spray regimes may enhance their effectiveness. Journal of Applied Chemistry and Agricultural Research Vol. 6 1999: pp. 100-104
