Abstract
A pot trial was conducted in 2010 and 2011 cropping seasons at the screen house of Michael Okpara University of Agriculture, Umudike to determine the potency of some plant extracts and pesticides for the control of bacterial leaf blight of cocoyam (Colocasia esculenta L.) Scholt. The materials employed include: lemon grass (Cymbopogon citrates). Black pepper seed (Piper guineense), orange peel (Citrus sinesis), streptomycin sulphate (antibiotic), copper oxychloride (fungicide) and sterile water (control). The experiment was laid in complete randomized design (CRD) and replicated six times. The plant materials used were first made into aqueous extracts using cold water extraction and diluted to 10% concentration. Application on leaves was by use of a hand sprayer for two weekly intervals. Data were collected on disease severity and incidence including growth parameters and on yield of corms. The results obtained showed that all the plant extracts were able to reduce disease and increase yield better than the untreated control.
