The effectiveness of various seed-tuber treatments was evaluated for control of silver scurf on potato (Solanum tuberosum), caused by Helminthosporium solani, at four locations in Washing-ton and Oregon using seed-tubers from the same source. Disease incidence was determined at harvest and following storage, and differed significantly among locations. The highest incidence of disease was observed at Redmond, OR and the lowest was at Hermiston, OR. Significantly less silver scurf occurred on progeny-tubers, regardless of location, when seed was treated with the fungicide treatments fludioxonil, fludioxonil + quintozene, azoxystrobin, or thiophanate-methyl + mancozeb compared with the nontreated control. A sample of H. solani from seed planted in the Columbia Basin of Washington and Oregon was assessed for resistance to thia-bendazole (TBZ) and thiophanate-methyl (TPM). Sensitivity of 20 isolates of H. solani to TBZ was determined on V8 media amended with TBZ. Four isolates, selected as a subset from the 20 isolates tested for TBZ sensitivity, were tested for resistance to TPM, mancozeb, and TPM + mancozeb on amended V8 media. Isolates differed significantly in sensitivity to both chemicals. Thirteen isolates out of the 20 tested were resistant to TBZ. One out of the four subsets of isolates was resistant to both TBZ and TPM. TBZ sensitivity was not related to geographic origin of the isolates. Variation in resistance was evident on a small scale as seen with one resistant and one sensitive isolate collected from the same tuber. This is the first report that silver scurf incidence is affected by location despite the same tuber-seed source and also the first report of TBZ and TPM resistant isolates of H. solani from the Columbia Basin (Oregon and Washington) production area.

Background and Aim: Indiscriminate and injudicious use of antibiotics in layer farms is a common practice of Bangladesh for the compensation of Poor management practices and ignorance. Despite this scenario, there is no published documentation on antibiotic usage pattern and farm management practices in layer farms. This study was undertaken to understand the farmers' perspective in small-scale layer farms regarding antibiotics usage and farm management. Materials and Methods: A questionnaire survey was conducted in 120 small-scale layer farms of Mymensingh district during January-February 2017. We only considered farms in production. Data were analyzed on antibiotic usage, purpose, egg management, understanding of antibiotic residue, withdrawal period, and other issues. Results: Among 120 farmers, about 94.16% of farmers are using antibiotics without respecting the withdrawal period. Only 39.1% of farmers possess knowledge of residues. In our surveyed farms, 91.83% of farmers are not practicing egg washing before supplying to the market and 52.67% of farmers are unaware of cleaning and disinfection of egg tray. Ten different types of antibiotics of seven classes have found in the survey. Most antibiotics are in the Watch (49%) and Reserve (8%) groups according to the WHO AWaRe categorization and 73% antibiotics are critically important for human medicine and are considered as last resort. Conclusion: This study found that due to the lack of knowledge and poor management, farmers consider using antibiotics as the most effective practices to control disease and enhancement of egg production. These indiscriminate uses of antibiotics are responsible for antibiotic residual and resistance problem. Here, we also provide some suggestion and guidelines to improve management practices to minimize the emerging problems of antimicrobial resistance through small-scale layer farms.
