The capability of endophytic Trichoderma spp. to reduce sheath blight disease in rice caused by Rhizoctonia solani was assessed under the growth conditions established practices System Rice Intensification (SRI), compared those standard irrigated cultivation. seeds inoculated with a local isolate fungus asperellum SL2 were grown respective SRI and conventional or uninoculated plants then infect...

Pea (Pisum sativum L.) is subjected to attack by certain soil-borne phylogenetic of fungus-like eukaryotic microorganisms such as Pythium debaryanum and fungi Rhizoctonia solani Fusarium which cause damping-off diseases. Isolation associated P. three species Trichoderma was carried out from soil rhizosphere pea plants. Antagonistic effect Rhizobium leguminosarum combined with lignorum, T. longi...

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...

in vitro and greenhouse studies were conducted to investigate the possibility of an interaction between two systemic insecticides of: thiodicarb (larvin df 80) and imidacloprid (guacho sw 70), and seedling disease organisms of: rhizoctonia solani, fusarium moniliforme and pythium ultimum. when in vitro concentrations of imidacloprid and thiodicarb were applied, a fungistatic activity occurred. ...

A series of benzimidazole phenylhydrazone derivatives (6a-6ai) were synthesized and characterized by ¹H-NMR, ESI-MS, and elemental analysis. The structure of 6b was further confirmed by single crystal X-ray diffraction as (E)-configuration. All the compounds were screened for antifungal activity against Rhizoctonia solani and Magnaporthe oryzae employing a mycelium growth rate method. Compound ...

Root rot is an important and widespread disease that often causes significant reduction in the yield and quality of harvested peas throughout the production areas in New York. Pea root rot can be caused by one of several soilborne pathogens or various combinations of root pathogens and also non-pathogens. In recent years, Fusarium solani f. sp. pisi (causal pathogen of Fusarium root rot) has be...

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...
