Bio – efficacy of Aqueous Plant Extracts and Cyperdicot on Insect Pests Infestation, Growth and Yield of Sweet Pepper (Capsicum annum L.) in the Dry Savanna of Nigeria

DEGRI M.M.

Abstract: Field experiments were conducted at the Faculty of Agriculture orchard farm, University of Maiduguri during 2011 and 2012 cropping seasons. The aim was to compare the efficacy of neem (Azaradichta indica) seed oil, garlic (Allium sativa) bulb and bitter leaf (Vernonia amygdalina) aqueous plant extracts with the synthetic insecticide cyperdicot 400 EC in the control of aphids on sweet pepper (Capsicum annum L.). The treatments consisted of three aqueous plant extracts at 50/0 w/v and cyperdicot 400 EC replicated four times including control in a randomized complete block design .Each plot measured 4.0 m by 3.0 m with 1.5 m inter-spaced per adjacent plot. Results of the study showed that neem seed oil and garlic treatments were effective against aphids as the synthetic insecticides cyperdicot in controlling sweet pepper aphids (Aphis gossypii). Cyperdicot 400 EC significantly (P≤0.05) reduced aphids infestation followed closely by neem seed oil and garlic bulb. Sweet pepper plant heights were significantly higher in neem seed oil and garlic extracts treatments than bitter leaf treated plants. Fruit number and fruit yield were also improved more than bitter leaf treated plots and control. Among the three aqueous plant extracts, neem seed oil and garlic extracts proved effective in controlling the pest, therefore they are recommended for controlling sweet pepper aphids due to their low cost, potency and efficacy.
