Resistance to conventional fungicides causes the poor disease control of agriculture. Natural products from plants have great potential as novel fungicide sources for controlling pathogenic fungi. In this study antipathogenic activity of the leaf essential oil and its constituents from Calocedrus macrolepis var. formosana Florin were evaluated in vitro against six plant pathogenic fungi. Chemic...

The effect of onion and garlic extracts on fungal growth and keratinolytic activity was studied in Trichophyton mentagrophytes as one of the major etiologic agents of human and animal dermatophytosis in Iran and other parts of the world. In order to find out the best keratinase producer for further steps, culture conditions for 30 strains of T. mentagrophytes isolated from human dermatophytosis...

The effects of osmotic and matric water potential on mycelial growth, production and germination of conidia, and production and maturation of pseudothecia of Pyrenophora triticirepentis (PTR), the cause of tan spot of wheat, were examined on clarified V8 juice agar amended with KCl or polyethylene glycol 8000 (PEG8000). Patterns of the growth responses of three isolates to decreasing osmotic an...

Frosty pod rot (FPR) of cacao is caused by Moniliophthora roreri (MR). Effective management must include chemical or biological control, in addition to agronomic tactics. Flutolanil has been effective controlling FPR. The objective this research was determine the response flutolanil MR isolates from Amazon and Coast regions Ecuador. Percentage mycelial growth inhibition (PGI), medium inhibitory...

The activity of the ATP:GTP 3'-pyrophosphotransferase (guanosine pentaphosphate synthetase I [GPSI]) from Streptomyces antibioticus is stimulated maximally by methanol at 20% (vol/vol) in assay mixtures. Although the enzyme is not activated by ribosomes, its activity is stimulated by tRNA (uncharged or charged) and by synthetic mRNA [e.g., poly(U)]. The level of stimulation is greater in the pr...
