The in vitro and growth chamber, tests were conducted order to assess the effects of B. amyloliquefaciens B18 subtilis S8 strains each alone combination with tebuconazole against F. culmorum (FC) isolate responsible Fusarium crown rot (FCR) durum wheat. was unaffected by 30 µg.mL-1 tebuconazole. Bacillus (at 106 CFU.mL-1) tebuconazole, alone, reduced mycelial growth, this effect significantly i...

A Gram-negative bacterial isolate, named PG4, was recovered from the rhizosphere of a tobacco plant (Nicotiana tabacum cv. Burley) and was identified as Lysobacter capsici based on the sequencing and phylogenetic analysis of 16S rRNA and characteristics in the Biolog Identification System. Strain PG4 showed chitinase and protease activity and was able to inhibit the growth of a broad range of p...

Bacillus subtilis is a Gram-positive and endospore producing bacterium. Limited studies have shown that lipopeptides produced by B. can be inhibitory to phytopathogens. Sclerotinia sclerotiorum plant pathogenic fungus which causes various diseases like cotton rot, watery soft stem crown rot blossom blight in vegetable crops. The objective of the study was isolate from their potential against S....

root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...

Rhizoctonia solani anastomosis group AG2-2 IIIB is a severe sugar beet and maize pathogen. It causes crown and root rot disease which le ads to y ield losses world-wide. The soil-borne pathogen is d ifficult to detec t and quantify by conventional methods. We developed a real-time PCR (qPCR) assay for the quantification of genomic DNA of Rhizoctonia solani AG2-2 IIIB based on the ITS region of ...

in order to detect hydrogen cyanide gene and to determine pseudomonas fluorescent efficiency in producing hydrogen cyanide for controlling the growth of rhizoctonia solanipathogen (the causal agent of sugar beet root and crown rot), samples were collected from sugar beet rhizosphere in sabzevar fields. after soil sampling and purification, 31 pseudomonas spp. isolates were separated on specific...

In this study, bacterial strains were isolated from soils from 30 locations of Samcheok, Gangwon province. Of the isolated strains, seven showed potential plant growth promoting and antagonistic activities. Based on cultural and morphological characterization, and 16S rRNA gene sequencing, these strains were identified as Paenibacillus species. All seven strains produced ammonia, cellulase, hyd...

Staniaszek M., Szczechura W., Marczewski W. (2014): Identification of a new molecular marker C2-25 linked to the Fusarium oxysporum f.sp. radicis-lycopersici resistance Frl gene in tomato. Czech J. Genet. Plant Breed., 50: 285–287. Fusarium oxysporum Schlecht. f.sp. radicis-lycopersici Jarvis & Schoemaker (FORL) is a saprophytic fungus, responsible for the fusarium crown and root rot disease in...

For reducing the post-harvest loss and extension of shelf-life of banana, it is treated with fungicide or combination of fungicide and hot-water treatment. A study was conducted for developing a method to control post-harvest diseases and extension of shelf-life of banana through non-chemical method of hot water treatment. The best treatment combination was found at 53 °C for 9 minutes. Shelf-l...
