Abstract
An experiment was conducted in Potiskum; southern sudan savanna and
Geidam; sahel savanna zones of Yobe state Nigeria to compare the effects of
onion bulb extract and balanite fruit extract with the synthetic insecticide
cypermethrin in the control of okra flea beetle Podagrica spp infesting okra.
The experiment was laid out in split plot design with four treatments
replicated three times. In each block the okra variety ladyfinger was assigned
to the main plots while onion bulb extract (125 g/ l)), balanite fruit extract
(10% w/v), Cypermethrin (10 ml/ liter of water) and untreated- control were
assigned to the subplot. Each experimental plot was sprayed with the treatments
according to the experimental design. Parameters assessed include number of
flea beetles (Podagrica spp) per plot, number of feeding holes per plant per
plot, number of fresh fruit yield and plant height per plot. The data obtained
revealed that in both locations (Potiskum and Geidam) significantly lower number
of okra flea beetles and feeding holes on okra leaves were recorded in the
plots sprayed with cypermethrin which was followed by the onion bulb extract
and the balanite fruit extract treated plots while significantly higher number
of flea beetles and feeding holes on okra leaves were recorded in the untreated
controls. It was also observed that significantly higher mean number of fresh
fruits per plant per plot and higher plant heights were recorded in the plots
sprayed with the synthetic insecticides; cypermethrin which was followed by the
onion bulb extract and balanite fruit extract treated plots while lower number
of fresh fruits and plant heights were recorded in the untreated control. Both
of the two tested botanicals are as effective as the synthetic insecticide;
cypermethrin and both can be recommended for use by the resource poor farmers
since both botanicals are cheap and readily available in the two location.
