Studies were conducted at two sites in South Dakota in 1992 and at one site in 1993 to measure the effect of velvetleaf on corn growth and yield. Velvetleaf was overseeded in corn rows and thinned to densities of 0, 1.3, 4, 12, and 24 plants/m2. Velvetleaf leaf area index and total biomass were positively correlated with velvetleaf density. Biomass per velvetleaf plant and corn biomass were correlated negatively with velvetleaf density. The percent corn yield reduction was similar for locations and years in spite of large yield differences. Maximum yield loss estimated by a hyperbolic yield reduction model was 37.2% with a loss of 4.4% per unit velvetleaf density.

This report indicates that Brassica carinata is a host for Macrophomina phaseolina and if susceptible crops (such as soybean and corn) are planted following B. carinata, presence of inoculum combined with drought conditions can favor charcoal rot development and cause yield loss.

Brassica carinata is an emerging oilseed crop in the United States, and root diseases caused by Fusarium have the potential to cause yield losses in production. In this study, B. carinata plants were randomly sampled at vegetative and seed development plant stages from South Dakota State University experimental plots. Reddish-brown lesions were observed on roots of sampled plants from which F. acuminatum, F. oxysporum, F. solani, and F. sporotrichioides were recovered. The Fusarium species were identified based on morphology and phylogenetic analyses of the translation elongation factor 1-α gene region. Pathogenicity of the four Fusarium species was evaluated on five B. carinata accessions using a modified inoculum layer method in the greenhouse. At 21 days after inoculation, root rot severity caused by Fusarium on the B. carinata accessions was assessed on a rating scale of 0 to 4 and evaluated using relative treatment effects (RTEs). The F. oxysporum isolate caused significant differences in RTE (P = 0.01) among the B. carinata accessions. However, there were no significant differences in RTE among the B. carinata accessions in response to F. acuminatum (P = 0.82), F. solani (P = 0.76), and F. sporotrichioides (P = 0.47) isolates.

Abstract The AMAGuides to the Evaluation of Permanent Impairment (AMA Guides) is the most widely used basis for determining impairment and is used in state workers’ compensation systems, federal systems, automobile casualty, and personal injury, as well as by the majority of state workers’ compensation jurisdictions. Two tables summarize the edition of the AMA Guides used and provide information by state. The fifth edition (2000) is the most commonly used edition: California, Delaware, Georgia, Hawaii, Kentucky, New Hampshire, Idaho, Indiana, Iowa, Kentucky, Massachusetts, Nevada, North Dakota, Ohio, Vermont, and Washington. Eleven states use the sixth edition (2007): Alaska, Arizona, Louisiana, Mississippi, Montana, New Mexico, Oklahoma, Pennsylvania, Rhode Island, Tennessee, and Wyoming. Eight states still commonly make use of the fourth edition (1993): Alabama, Arkansas, Kansas, Maine, Maryland, South Dakota, Texas, and West Virginia. Two states use the Third Edition, Revised (1990): Colorado and Oregon. Connecticut does not stipulate which edition of the AMA Guides to use. Six states use their own state specific guidelines (Florida, Illinois, Minnesota, New York, North Carolina, and Wisconsin), and six states do not specify a specific guideline (Michigan, Missouri, Nebraska, New Jersey, South Carolina, and Virginia). Statutes may or may not specify which edition of the AMA Guides to use. Some states use their own guidelines for specific problems and use the Guides for other issues.
