The Effects of Some Bio-Nematicides on the Productivity of Capsicum annum

Biopesticides have found intrinsic application in the control of plant pests and diseases, due to their eco-friendly activities and bioavailability as opposed to synthetic pesticides. Nematode infestation has become a major problem associated with poor yield and low economic value of farm produce. The height and dry shoot weight (DSW), of C. annum (pepper plant), treated with some potential nematicides (Azadirachta indica, Vernonia amygdalina, Manihot esculenta, Carica papaya. and Citrus sinensis), were investigated ex-situ. The investigation was carried out in a two trials, within exposure periods of 30, 60 and 90-days, at different concentrations of 20, 30 and 40g. Results showed that, compared to the control, all treatments similarly demonstrated significant improvement in the monitored parameters of both trials (p < 0.05). Thus the applied treatment significantly (p < 0.05), improved productivity of C. annum induced due to their varying degrees of nematotoxicity. Based on the findings of this research, we therefore conclude that the application of the treatments (i.e. bionematicides), can improve the productivity of Capsicum plant
