Taxonomic studies were made on Streptomyces species, causal organisms of potato common scab, isolated from lesions of potato tubers and sugar beet roots in Japan. They were divided into two groups based on the spore chain morphology: spiral spore chain isolates (SI) group and rectiflexible spore chain isolates (RFI) one. Although the two groups did not significanlty differ each other in their p...

INTRODUCTION: Head scab caused by Fusarium graminaerum (Schwabe) has caused significant losses in the soft red winter wheat crop in Kentucky and in small grain crops in many regions of North America. Damage from head scab results in reductions in seed quality, emergence, and yield of wheat. In addition, losses in food-grain quality are caused by production of fungal mycotoxins, specifically vom...

Quinone outside inhibitors (QoI) fungicides group were introduced for commercial use against apple scab (Venturia inaequalis) in Israel 1997. Unlike other regions the world, which resistance of V. inaequalis to QoI was observed within 3–5 years use, it only occurred after 14 use. Field trials conducted between 2007 and 2017 showed a significant reduction susceptibility QoIs northern since 2011....

Pseudomonas fluorescens LBUM223 is a plant growth-promoting rhizobacterium (PGPR) with biocontrol activity against various plant pathogens. It produces the antimicrobial metabolite phenazine-1-carboxylic acid, which is involved in the biocontrol of Streptomyces scabies, the causal agent of common scab of potato. Here, we report the complete genome sequence of P. fluorescens LBUM223.

As part of a research programme designed to identify biological agents for the control of sheep scab, the pathogenicity of the fungus Metarhizium anisopliae to Psoroptes mites in the presence of sheepskin and wool was examined in the laboratory. No inhibitory effects of skin and wool were observed and high levels of infection were recorded. Subsequently the pathogenicity of formulations of both...

Scanning surveillance facilitates the monitoring of many endemic diseases livestock in Great Britain, including sheep scab, an ectoparasitic disease major welfare and economic burden. There is, however, a drive to improve cost-effectiveness animal health surveillance, for example by thoroughly exploiting existing data sources. By analysing Veterinary Investigation Diagnosis Analysis (VIDA) data...

Apple scab caused by the pathogenic fungus Venturia inaequalis causes significant damage to apples. The creation of apple-scab resistant varieties is considered an alternative pesticide-based management. To evaluate R gene inheritance, 862 apple hybrid samples were analyzed and divided into populations depending on resistance genes (Rvi6 Rvi5) present in parents’ genotypes their combinations. f...

One of the greatest problems in breeding for Fusarium head blight (FHB) resistance lies in the difficulty of assessing the disease. Air separation methods have long been used in the seed industry for seed conditioning purposes and in seed labs to measure the proportion of different components of seed samples. An air separation machine was specifically developed from a Precision Machine head thr...
