ABSTRACT

Field experiment was conducted at Galma Bizzara, Zaria during the 2015 dry season. Two different botanicals pawpaw (Carica papaya) and moringa (Moringa oleifera), were compared against Cypermethrin for the management of Aphiscraccivora (Koch)population on Cabbage (Brassica oleracea L.). The experiment consisted of four treatments laid in Randomized Completely Block Design (RCBD) replicated five times. Each plot was 4m by 3m. Moringa and pawpaw leaves were air-dried at room temperature (25oC) and pounded into powdery form. 20g each of pawpaw (Carica papaya) and Moringa (Moringa oleifera)leaf powders were soaked separately into 1 litre of water overnight prior to spray. Muslin cloth was used to squeeze and prevent foreign particles into the aqueous solution of moringa and pawpaw. Visual assessment was used to count the number of Aphis per plant. The efficacy of the standard (Cypermethrin) on mean population of A.craccivora was highly significant compared to Moringa leaf which was also significantly more efficient than pawpaw leaf at the first spray (p<0.05). In the second spray however, Cypermethrin gave the overall best effect while there was no significant difference between Moringa and Pawpaw leaves. From this study, Moringa could be a use for the management of A.craccivorapopulation on cabbage in place of the synthetic pesticide (Cypermethrin).
