Experiment was carried out in 2006 and 2007 cropping seasons at Adamawa State University, Mubi experimental farm. The experiment was to sort for safer, affordable, available control measure to cowpea (vigna ungniculate) pest for the poor resource farmers who are involved in the highest percentage production. The research was to investigate the effect of karate 25Ec, neem need aqueous extract and cigarette filter extract on the yield of Ife-brown in Mubi. Four chemicals karate 25Ec, neem seed aqueous extract, cigarette filter extract and the combination of the three chemicals were used. Control plots were laid down in series of similar experiment in a randomized complete block design (RCBD). Data were collected and analysed. The result in 2006 and 2007 showed that the combination of karate25Ec, neem seed aqueous extract and cigarette filter extract recorded the highest weight of 380.09g and 490.00 the control plot recorded the lowest weight of 165.16g and 162.15g respectively.
