Agricultural and wild ecosystems may interact through shared pathogens such as Macrophomina phaseolina, a generalist clonal fungus with more than 284 plant hosts that is likely to become more important under climate change scenarios of increased heat and drought stress. To evaluate the degree of subdivision in populations of M. phaseolina in Kansas agriculture and wildlands, we compared 143 iso...

Macrophomina phaseolina é um fitopatógeno de solo com ampla distribuição geográfica, responsável por ocasionar perdas econômicas graves incitando sintomas podridões no sistema radicular e caule das plantas infectadas. Há uma demanda mundial crescente novos tratamentos, que promovam a segurança alimentar nutricional, substâncias mais eficazes menos danosas ao equilíbrio dos ecossistemas. O objet...

Fungi of the genus Trichoderma are used as biocontrol agents against several plant pathogenic fungi like Rhizoctonia spp., Pythium spp., Botrytis cinerea and Fusarium spp. which cause both soil-borne and leaf- or flower-borne diseases of agricultural plants. Plant disease control by Trichoderma is based on complex interactions between Trichoderma, the plant pathogen and the plant. Until now, tw...

A marine Ascidian-associated fungus, Trichoderma harzianum, (NIO/BCC2000-51) was assessed for its in vitro antagonistic activity against ten fungal phytopathogens and three food-infesting fungi. Fractionation of the cell-free culture filtrate of T. harzianum (NIO/BCC2000-51) showed its ethyl acetate (EA) fraction to be significantly active against fungal phytopathogens; Macrophomina sp, Pyricul...

we assessed a collection of 47 fluorescent pseudomonas spp., some with known biological     control activity against certain soil-borne phytopathogenic fungi such as, macrophomina phaseolina, rhizoctonia solani, phytophthora nicotianae var. parasitica, pythium sp. and  fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, hcn and protease. the resu...
