Alternatives to Methyl Bromide for control of Soil-Borne Diseases in Bare Root Forest Nurseries

The objective of the project is to develop alternatives to methyl bromide and other chemical soil fumigants through implementation of comprehensive integrated pest management practices in bareroot forest nurseries. Within this broad objective we are conducting field experiments to evaluate the basis for fumigation in nurseries with respect to cropping and soil treatment practices in order to develop effective alternative management practices which minimize incidence and severity of disease. Together with field studies, greenhouse and laboratory studies are aimed at better understanding the genetic basis for pathogenicity of Fusarium oxysporum f. sp. pini, and the dynamics of pathogen populations in nurseries to better predict disease potential.
