Broad spectrum weed control is essential for successful lesquerella [Lesquerella fendleri (Gray) Wats., Brassicaceae] production. Weeds must be controlled during establishment and throughout the growing season. Lesquerella seedlings grow slowly following germination and emergence, and cannot compete well with most broadleaf and grass weeds. Weed competition is particularly critical prior to clo...

Fluorescent pseudomonads were a major component [log (10) 4.2-6.1 colony-forming units mL-1] of the culturable heterotrophic gram-negative bacterioplankton observed in three Mississippi Delta oxbow lakes in this study. Pure cultures of fluorescent pseudomonads were isolated from three Mississippi Delta oxbow lakes (18 per lake), using selective media S-1. Classical physiological tests and Biolo...

BACKGROUND The State of California maintains a comprehensive Pesticide Use Reporting Database (CPUR). The California Department of Water Resources (CDWR) maps all crops in agricultural counties in California about once every 5 years. OBJECTIVE We integrated crop maps with CPUR to more accurately locate where pesticides are applied and evaluated the effects for exposure assessment. METHODS W...

OBJECTIVE To evaluate the relationship between pesticide use and myocardial infarction (MI) among farm women. BACKGROUND Little is known about the potential association between pesticide use and cardiovascular outcomes. METHODS We used logistic regression to evaluate pesticide use and self-reported incident nonfatal MI among women in the Agricultural Health Study. RESULTS Of those MI-free...
