1-Hydroxyphenazine (1-OH-PHZ), a natural product from Pseudomonas aeruginosa strain SD12, was earlier reported to have potent antifungal activity against Rhizoctonia solani. In the present work, the antifungal activity of 1-OH-PHZ on 40S ribosomal S9 protein was validated by molecular docking approach. 1-OH-PHZ showed interaction with two polar contacts with residues, Arg69 and Phe19, which inh...

This study tests the effect of glyphosate application on disease severity in glyphosate-resistant sugar beet, and examines whether the increase in disease is fungal or plant mediated. In greenhouse studies of glyphosate-resistant sugar beet, increased disease severity was observed following glyphosate application and inoculation with certain isolates of Rhizoctonia solani Kuhn and Fusarium oxys...

The antagonistic potential of seven species native Trichoderma against Rhizoctonia solani f.sp. sasakii were evaluated in dual culture method which includes T. asperellum (KU933476), koningiopsis (KU904460), Hypocrea lixii (KX0113223), harzianum (KU933471), ovalisporum (KU904456), (KU904458), atroviridae (KU933472). Among them showed highest inhibition percentage (78.09%), followed by (70.95%),...

Expression of the linear DNA plasmid-encoded protein (RS224) from the plant-pathogenic fungus Rhizoctonia solani isolate H-16, anastomosis group 2-2, and its localization were studied. Extracts from Escherichia coli cells expressing the open reading frame (ORF) of RS224 (RS224ORF in pRS224) contain a 92-kDa T7.Tag-RS224orf fusion protein. Antisera raised against the fusion protein obtained from...

A study was undertaken to explore the effect of volatile oils from Eucalyptus citriodora and its major constituent citronellal against two well-known rice pathogens, Rhizoctonia solani and Helminthosporium oryzae. The radial growth and dry weight of both the test fungi were drastically reduced in response to the volatile oils. A complete inhibition of R. solani and H. oryzae was observed at 10 ...

A series of pyrazole carboxamide and isoxazolol pyrazole carboxylate derivatives were designed and synthesized in this study. The structures of the compounds were elucidated based on spectral data (infrared, proton nuclear magnetic resonance and mass spectroscopy). Then, all of the compounds were bioassayed in vitro against four types of phytopathogenic fungi (Alternaria porri, Marssonina coron...

Biocontrol of Rhizoctonia solani in tomatoes cultivated under greenhouse and field conditions was analyzed using the Trichoderma harzianum mutants Th650-NG7, Th11A80.1, Th12A40.1, Th12C40.1 and Th12A10.1 and ThF2-1, respectively. Their innocuousness on tomato cultivars 92.95 and Gondola (greenhouse assays), and on cultivar Fortaleza (field assays) was established. Alginate pellets (1.7 g pellet...

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...

متابولیت‌های ثانویه گیاهی، به دلیل داشتن خواص ضدمیکروبی و آنتی‌اکسیدانی جایگاه ویژه‌ای در کنترل عوامل بیماری‌زا گیاهی دارند. در همین راستا اثر ضدقارچی سه اسانس مرزه بختیاری ((Satureja bachtiarica ، دارچین ((Cinamomum zeylancium و رازیانه ( (Foeniculum vulgare بر رشد سه گونه قارچ مهم بیماری‌زای گیاهی Fusarium oxysporumو Fusarium solani و Pyrenephora graminea مورد مطالعه قرار گرفت. بعد از خشک شدن...
