Abstract

Effect of two aqueous plant extracts were tested on fungal organisms associated with diseased mustard at Central Laboratory, National Root Crops Research Institute (NRCRI), Umudike, Abia State. The diseased mustard seedlings were sourced from an existing experimental field during 2022 cropping season at Teaching and Research Farm, Federal College of Agriculture, Ishiagu, Ebonyi State, Nigeria. Aqueous leaf extracts from Fiscus exasperata and Calotropis procera were used to inhibit the growth of the mycelial fungus at 0.5,1.0 and 1.5 w/v concentration levels in a Completely Randomised Design and replicated three times. Data collected were subjected to Analysis of Variance (ANOVA) using Minitab Version 17 and the means were separated using Tukey test at P

<0.05. The results revealed five fungi organisms belonging to four genera were isolated which includes Trichoderma species, Fusarium oxysporum, Sclerotium species, Fusarium solani and Alternaria species. The results showed that Fusarium solani had the highest percentage of occurrence (32.56 %), followed by Alternaria species (25.58 %) while Trichoderma species had the least (4.65 %). The inhibitory effect of C. Procera ranged from 3.73 to 93.39 % with Fusarium solani and Trichoderma species respectively across the three concentration levels. Similarly, the inhibitory effect of F. exasperata ranged from 2.33 to 89.59 % with Fusarium solani and Trichoderma species respectively across the three concentration levels. Therefore, the potentials of these two aqueous extracts on the inhibition of mycelial growth of fungal organisms associated with mustard diseases are worthy. This study showed the prospect of Fiscus exeparata and Calotropis procera in the control of fungal disease of mustard and a possible alternative to chemical pesticides.
