sugar beet roots and attached soil are usually transferred to sugar factories for processing ,then the roots are washed by pressurized water. muddy water as waste flows in canal and is used to irrigate fields. the possibility of occurrence and fluctuations of the pathogenic organisms in waste were studied in 2005. the samples were collected from waste water once a week. isolation of pathogens w...

Ginseng damping-off, caused by the fungal pathogens Rhizoctonia solani and Pythium sp., is a critical disease in ginseng seedling. In a continuing effort to find microorganisms with the potential of acting as a biocontrol agent against Rhizoctonia damping-off, we found that a Streptomyces sp. A501 showed significant antifungal activity against Rhizoctonia solani. In field experiment to test the...

Pseudomonas sp. strain 2-92, isolated from a Canadian field plot under long-term mineral fertilization, strongly inhibits the growth of Fusarium graminearum, Rhizoctonia solani, and Gaeumannomyces graminis. Here, we report the draft genome sequence of Pseudomonas sp. strain 2-92.

We have tested whether a gene encoding a polygalacturonase-inhibiting protein (PGIP) protects tobacco against a fungal pathogen (Rhizoctonia solani) and two oomycetes (Phytophthora parasitica var. nicotianae and Peronospora hyoscyami f. sp. tabacina). The trials were performed in greenhouse conditions for R. solani and P. parasitica and in the field for P. hyoscyami. Our results show that expre...

Seed health testing by studying the seed-borne fungi of soybean seeds is an important step in the management of the seed-borne diseases. In the present study seed-borne fungi was studied by using agar plate method. A number of seed-borne fungal species was isolated from the agar plate. These seed-borne fungal sps. were Aspergillus niger, A. flavus, A. fumigatus, Chaetomium globosum, Curvularia ...
