Colletotrichum truncatum, a potential mycoherbicide for control of hemp sesbania, formed spontaneous variants on agar medium. The predominant variant produced more spores than the wild type on potato dextrose agar but the wild type produced more spores on Czapek-Dox agar. Spore yield of both types was greatly reduced on Czapek-Dox. In liquid culture, the variant spontaneously arose and graduall...

striga hermonthica is a parasitic weed which largely constrains maize and sorghum production in western kenya. the weed mostly invades small scale farms and depending on severity, it may cause damage ranging from 10% to complete crop failure thereby aggravating the food insecurity in that region. this study aimed at evaluating fungal isolates as possible biocontrol agents against the weed. fung...

We characterized the biosynthesis of indole-3-acetic acid by the mycoherbicide Colletotrichum gloeosporioides f. sp. aeschynomene. Auxin production was tryptophan dependent. Compounds from the indole-3-acetamide and indole-3-pyruvic acid pathways were detected in culture filtrates. Feeding experiments and in vitro assay confirmed the presence of both pathways. Indole-3-acetamide was the major p...

The aim of this study was to evaluate the antifungal potential of moss Bryum argentium, and Bryum cellulare against the phytopathogenic fungi Curvularia lunata, the causal organism of leaf spot of Zea mays using pour plate method. A phytochemical screening of the extracts was also carried out to determine the antifungal substances present in both the bryophytes. The results revealed that the ra...
