Herein, we report the first occurrence of web blight of rosemary caused by Rhizoctonia solani AG-1-IB in Gangneung, Gangwon Province, Korea, in August 2014. The leaf tissues of infected rosemary plants were blighted and white mycelial growth was seen on the stems. The fungus was isolated from diseased leaf tissue and cultured on potato dextrose agar for identification. The young hyphae had acut...

The antifungal activity of ethanol extract of Silybum marianum was investigated invitro against three strains of Rhizoctonia solani at different concentrations (5, 10, 15 and 20%). Bioassay of extract was conducted by poisoned food technique with three replications. The findings showed that strain of R. solani (Eggplant) was susceptible to concentrations of S. marianum more than other strains i...

Damping off caused by Rhizoctonia solani (isolate AG4) constrains growing soybean in the north Iranian province of Golestan. The pathogen was grown on malt agar containing 0, 50, 100 or 200 ppm trifluralin then its vegetative growth and virulence were evaluated. The response of soybean cv. Williams seedlings grown in soil containing 0, 0.5, 1 and 2 ?g ai g-1 trifluralin was investigated. On mal...

Pseudomonas CMR12a was previously selected as an efficient biocontrol strain producing phenazines and cyclic lipopeptides (CLPs). In this study, biocontrol capacity of Pseudomonas CMR12a against Rhizoctonia root rot of bean and the involvement of phenazines and CLPs in this ability were tested. Two different anastomosis groups (AGs) of Rhizoctonia solani, the intermediately aggressive AG 2-2 an...

HOWELL, C. R. 1978. Seed treatment with L-sorbose to control damping-off of cotton seedlings by Rhizoctonia solani. Phytopathology 68:1096-1098. The keto sugar, L-sorbose, inhibits hyphal extension and accumulate in the soil. When applied to seed in crystalline promotes profuse branching in Rhizoctonia solani. When form with sticker, L-sorbose is highly water soluble and may applied to cotton s...

A two-step method was developed to evaluate potato resistance to black scurf caused by Rhizoctonia solani. Tuber piece inoculum was first conducted in the laboratory, which was also first reported in this study. After inoculation with pathogen discs and culture for 48 h, the necrotic spots on the inoculated potato pieces were generated and measured by the crossing method. Further evaluation was...

Rhizoctonia muneratii ATCC 13247 was capable of catalyzing the conversion of 25-hydroxycholesterol to the 3-oxo-4-ene. Hydroxylation at the 6alpha and 6beta positions with the concomitant 3-oxo-4-ene transformation was also observed. The addition of Triton X-100 to the growth medium immediately before steroid addition selectively prevented the appearance of the respective 6alpha-hydroxylated pr...

During late August and early September 2011, stem rot symptoms were observed on adzuki bean plants (Vigna angularis) growing in fields located in Beijing and Hebei Province, China, respectively. In this study, four isolates were obtained from infected stems of adzuki bean plants. Based on their morphology, and sequence and polymerase chain reaction-restriction fragment length polymorphism (PCR-...

A series of novel fused heterocyclic compounds bearing benzo[4,5]imidazo[1,2-d][1,2,4]triazine 4a-4w were designed and conveniently synthesized via the intermediates 2-(halogenated alkyl)-1H-benzo[d]imidazoles 2a, 2b, and 2-((1-(substituted phenyl)hydrazinyl)alkyl)-1H-benzo[d]imidazoles 3a-3g. The structures of all target compounds were characterized by FT-IR, ¹H NMR, 13C NMR, and EI-MS, of whi...

A novel slightly distorted octahedral complex of Cr(III) of norfloxacin (Nor) with the formula [Cr(III)(Nor)(Bipy)Cl2]Cl·2CH3OH has been synthesized hydrothermally in the presence of a N-containing heterocyclic compound 2,2'-bipyridyl (Bipy). The complex was characterized with FT-IR, elemental analysis, UV-visible spectroscopy, and X-ray crystallography. Spectral studies suggest that the Nor ac...
