Fungicidal efficacy of crude extracts from some indigenous plants against fungal pathogens associated with tomato (Solanum lycopersicum L.) fruit rots

Abstract

The research work was conducted in the biology laboratory of federal college of forestry Jos (latitude 7o11’N and longitude 7o38’E) in 2016. The objectives of the study were to determine the occurrence of rot fungi in Jos north and Bassa local government areas of Plateau state, to assess the fungicidal effect of crude extracts from some selected indigenous plants on two most prevalent rot fungi and to assess the best concentration of the extracts that is comparable to synthetic fungicide. The treatments were four varying concentrations (75g/l, 100g/l, 150g/l and 200 g/l) for each plant, standard fungicide (Carbendazim at 2g/l), and control laid in a Completely Randomized Design (CRD) with three replications. In general, Azadirachta indica gave the best reduction for radial mycelial growth (1.65 cm) on Aspergillus niger and (1.50 cm) on Rhizopus stolonifer compared to the controls (7.67 cm) for Aspergillus niger and (8.40 cm) for Rhizopus stolonifer
