Lumsden, R. D., and Locke, J. C. 1989. Biological control of damping-off caused by Pythium ultimum and Rhizoctonia solani with Gliocladium virens in soilless mix. Phytopathology 79:361-366. Gliocladium virens controlled damping-off of zinnia, cotton, and Disease control efficacy lasted for at least 2 mo when G. virens was cabbage caused by Pythium ultimum or Rhizoctonia solani in nonsterile int...

Recently, codes over some special finite rings especially chain rings have been studied. More recently, codes over finite non-chain rings have been also considered. Study on codes over such rings or rings in general is motivated by the existence of some special maps called Gray maps whose images give codes over fields. Quantum error-correcting (QEC) codes play a crucial role in protecting quantum ...

The pathological findings in three cases of equine phycomycosis in Costa Rica are described. Two cutaneous (Pythium sp) and one nasal lesion (Conidiobolus) were observed.

abstract some agricultural fields of razevi and north khorasan provinces were sampled for identification and resistance to metalaxyl of pythium ultimum species isolates. isolation was done between years of 2007 to 2009. van der plaats- niterink key to species of pythium and specific its region of rdna were used for morphological and molecular identification respectively. micrometric characteris...

Three new species of Pythium, namely, P. oopapillum, P. emineosum and P. camurandrum are presented in this paper based on morphological descriptions and molecular phylogenetic characterisation. These new species were isolated from various ecological regions in Canada. They have unique morphological features in the genus Pythium, and form distinct clades in maximum parsimony analyses, which are ...

A series of some novel 1,2,4-triazol-5(4H)-one derivatives were designed and synthesized under microwave irradiation via multistep reaction. The structures of 1,2,4-triazoles were confirmed by (1)H NMR, MS, FTIR, and elemental analysis. The antifungal activities of 1,2,4-triazoles were determined. The antifungal activity results indicated that the compounds 5c, 5f, and 5h exhibited good activit...

in order to study the role of pythium species associated with cantaloupe root and crown rot, samples were collected from infected fields in different areas of khorasan razavi province during 2009-2010. the root pieces were washed and cultured on cma-parp medium. the pythium isolates were then purified by hyphal tip method and identified based on van der plaats-niterink mycological key. the path...
