STUDIES ON THE LEAF SPOT DISEASE OF EGGPLANT (SOLANUM AETHIOPICUM L.) AND ITS MANAGEMENT WITH SOME BOTANICAL

ABSTRACT

Field, greenhouse and laboratory studies were carried out at the Department of Crop Science,

University of Nigeria, Nsukka in order to evaluate the leaf spot disease of eggplant and its

management with some botanicals. Field survey of diseased plants was conducted on

eggplant farm. Solanum aethiopicum L. plants were sampled on every 1 m distance along the

diagonal transects for disease incidence and severity. Pathogen isolation from severely

infected leaves was carried out in the laboratory where the diseased leaves were plated on

fresh Potato Dextrose Agar. Identification of the isolated fungi was carried out with the aid of

identification scheme based on their cultural characteristics. Nursery preparation for raising

eggplants used in the green house was also carried out on a sterilized soil. The five most

abundant pathogens isolated were inoculated separately on the seedlings of eggplant in five

replicates.

The experiment was arranged in a completely randomized design. Phytochemical

contents of the four plant extracts were determined in the laboratory. An in vitro control of the

organism responsible for the leaf spots was carried out using plant extracts at 0.030 g/ml,

0.060 g/ml, and 0.120 g/ml and 0.250 g/ml concentrations. The experimental design was a

9×4 factorial in a completely randomized design (CRD). The data were analyzed using

analysis of variance (ANOVA). Means were later separated using Fisher’s least significant

difference (F-LSD). Helminthosporium infestans Dur. & Mont, Cladophialophora carrionii

Trejos, Aspergillus niger van Tieghem, Rhizopus nigricans Ehrenb and Neurospora africana

Huang & Backus were isolated from the diseased eggplant leaves. H. infestans recorded the

highest percentage frequency (61.11 %) while A.

niger had the lowest percentage frequency

(5.56 %). H. infestans was pathogenic to eggplant seedlings. The Koch postulate test

confirmed H. infestans as the causal organism of the spots symptoms. The qualitative

phytochemical analysis on the test plants revealed the presence of tannin, soluble

carbohydrate, hydrogen cyanide, steroids, flavonoids, alkaloids as well as glucosides in all

the extracts analyzed. The effect of ethanolic extracts of the test plants significantly (Preduced the incidence and severity of the pathogen. Anti-fungal activity of seed extracts of G.

kola on H. infestans was highest at 0.0120 g/ml concentrations. G. kola could be used as

fungicide to manage leaf spot in eggplant because of its availability and eco-friendliness.
