ABSTRACT:
The
efficacy of 5% Monodra seed Petroleum ether extract (5% MSEE), 5% Jatropha seed
petroleum ether extract (5% JSEE), 5% Monodroa seed water extract (5% MSWE), 5%
Japtropha seed water extract and a standard synthetic insecticide,
Lamdacyhaiothrin (25g a.i./ha) were evaluated in the field during the early
season fir their effectiveness in the control of spp, the major insect pests of
Okra. All treatments, except the 5% JSWE, significantly reduced (P =0.5) the
population of the pests with Lamdacyhalothrin proving more superior in
efficacy. The ranking of effectiveness in the control of Podagrica spp was;
Lamdacyhaiothrin > 5% MSEE > 5% JSEE > JSWE > Control. The
Lamdacyhalothrin had a higher resuduak effect when compared with the other
treatments, while the ether extracts had greater residual effects when compared
with the water extracts and control. There was significant difference in the
total fruit yield (t - I) = ( tons ha 1) obtained in the Lamdacyhalothrin-treated
plots and other treatments; and the yields from the plots treated with the ether
extracts of the two botanivals were also significantly higher than the control.
The correlation coefficient (r = - 0.96) showed that the total fruit yield
produced were affected negatively by the level of defoliation on the leaves.
The ether extracts of the two botanicals showed good promise as substitute for
the area. Perhaps, higher dosages of the products and closer spray regime may
improve their efficacy.
