ABSTRACT The influence of varying environmental and cropping conditions including temperature, light, soil type, pathogen isolate and race, and cultivar of tomato on biological control of Fusarium wilt of tomato by isolates of nonpathogenic Fusarium oxysporum (CS-20 and CS-24) and F. solani (CS-1) was evaluated in greenhouse and growth chamber experiments.(More)
Integrating multiple soil and disease management practices may improve crop productivity and disease control, but potential interactions and limitations need to be determined. Three different potential disease-suppressive management practices, including a Brassica napus (rapeseed) green manure rotation crop, conifer-based compost amendment, and three(More)
Soilborne potato diseases are persistent problems in potato production and alternative management practices are needed. In this research, biocontrol agents (Bacillus subtilis GB03 and Rhizoctonia solani hypovirulent isolate Rhs1A1) and compost amendments (from different source material), were evaluated alone and in combination, for their potential to reduce(More)
Soilborne potato diseases are persistent problems in potato production. Use of disease-suppressive rotation crops, such as Brassica spp. (mustards, rapeseed) and sudangrass, has shown potential for management of soilborne diseases and enhanced yield in various crop production systems. However, how to best implement these crops into productive potato(More)
Maine consistently ranks in the top ten potato (Solanum tuberosum L.) production areas though yields are substantially lower than the mid- and western USA. Geospatial frameworks help resolve patterns and trends in production environments (at multiple scales) that may enable improvements in adaptive management strategies which enhance yield, increase(More)

Rats were given bilateral injections of 1-2 mul procaine HCl solution (50 mug/mul) in the region of the ventromedial hypothalamus. Normal-sized meals occurred reliably with a latency of 16-120 sec, indicating that this region has the function of inhibiting onset of eating, not just the function of stopping a meal. Food-rewarded fixed-ratio-of-one (FR 1;(More)
