To explore the pathogenesis of Rhizoctonia solani and its phytotoxin phenylacetic acid (PAA) on maize leaves and sheaths, treated leaf and sheath tissues were analyzed and interpreted by ultra-performance liquid chromatography-mass spectrometry combined with chemometrics. The PAA treatment had similar effects to those of R. solani on maize leaves regarding the metabolism of traumatin, phytosphi...

in vitro studies with trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. microscopic observations showed that t. harzianm and t. viride, isolated from soil samples from ahwaz and karaj, adversely affected the mycelial ...

ABSTRACT The biochemical defense mechanisms of amphibians involve cutaneous secretions bioactive molecules with antimicrobial activity. This study evaluated the in vitro activity methanolic extracts from two amphibian species Bufonidae family, Rhaebo guttatus and Rhinella marina, control phytopathogens Fusarium udum, solani, Colletotrichum truncatum, Aspergillus flavus, Rhizoctonia Macrophomina...

Rhizoctonia solani (Teleomorph: Thanatephorus cucumeris, T. praticola) is a basidiomycetous fungus and a major cause of root diseases of economically important plants. Various isolates of this fungus are also beneficially associated with orchids, may serve as biocontrol agents or remain as saprophytes with roles in decaying and recycling of soil organic matter. R. solani displays several hyphal...

SUMMARY Sheath blight, caused by the fungus Rhizoctonia solani, is a major disease of rice world-wide, but little is known about the host response to infection. The objective of this study was to identify proteins and DNA markers in resistant and susceptible rice associated with response to infection by R. solani. Replicated two-dimensional polyacrylamide gel electrophoresis experiments were co...

background and purpose: fusarium species are avid producers of secondary toxic and carcinogenic metabolites such as fumonisin. contamination of food and feed products with fumonisin can be hazardous to the health of humans and animals and may lead to agricultural loss. accordingly, in this study, we aimed to evaluate the effects of candida parapsilosis on the growth and fumonisin production of ...

Aqueous leaf extract of four different species of Datura viz. D.stramonium L., D. innoxia Mill.Gard, D. metal L. and D. ferox L. Amoen were tested for their antifungal activity against phytopathogenic molds in terms of mycelial growth of Alternaria solani and Fusarium oxysporum f.sp. udum causing early blight of tomato and wilt of pigeonpea respectively. The extract of Datura sp. at 5, 10, 15 a...

The effect of five antioxidants (citric acid, salicylic acid, benzoic acid, ascorbic acid, and sodium citrate) on the resistance of tomato plants (Lycopersicon esculentum Mill) to early blight disease incited by Alternaria solani was investigated in vitro and in vivo. The results indicated that all of the antioxidants tested markedly inhibited the mycelial growth of A. solani in vitro. The degr...
