Bhut jolokia (Capsicum chinense Jacq.) is one of the world’s hottest chilli entered in the Guinness book of world record (2006). Many pest and diseases ruined Bhut jolokia and among them damping-off disease of seedling as well root and stem rot in young transplants caused by Rhizoctonia solani is one of the important limiting factor in cultivation and production (Ngullie and Daiho, 2013). Even ...

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 diseases have long been prevalent in Australian grain-growing regions, and most management decisions to reduce the risk of yield loss need to be implemented before the crop is sown. The levels of pathogens that cause the major root diseases can be measured using DNA-based services such as PreDicta B. Although these pathogens are often studied individually, in the field they often occur as ...

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...

Potato (Solanum tuberosum L.) an agro-economically important food crop in the world, is sensitive to many fungal pathogens including Rhizoctonia solani (AG-3), the causal agent of stem and root rot diseases. Chitinase and glucanase are cell wall degrading enzymes which have been shown to have high antifungal activity against a wide range of phytopathogenic fungi. In the present study, plasmid p...

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...

The genus Lysobacter includes several species that produce a range of extracellular enzymes and other metabolites with activity against bacteria, fungi, oomycetes, and nematodes. Lysobacter species were found to be more abundant in soil suppressive against the fungal root pathogen Rhizoctonia solani, but their actual role in disease suppression is still unclear. Here, the antifungal and plant g...
