Using the natural enemies of the pathogens in combination with improved early detection methods will not only enhance disease control but also lead to reduced pesticide use and accumulation in the environment. The majority of scientists at PMRC have one or more MII projects underway. George Lazarovits and the Fats and Proteins Foundation and Rothsay are examining the use of proteinaceous animal byproducts as soil amendments for the control of soilborne plant pathogens. Stephanie Hilton and Cyanamid Crop Protection are investigating reduced rates of a soil treatment for cabbage maggot control in crucifers. The crucifer beetle, Phyllotreta cruciferae , and the striped crucifer beetle, P. striolata , are highly attracted to Indian mustard.
Indian mustard contains elevated levels of glucosinolates that stimulate feeding.
In growers' fields, beetles congregate on the trap crop and avoid feeding on the commercial crop. Adoption of this technique eliminates the need for early season applications of foliar insecticides to control flea beetles. Plantings of Indian mustard also appear to enhance the activity of biological control agents. Large numbers of several species of parasites and predators can be found on these plants throughout the season. Indian mustard provides a suitable refuge and an abundance of prey for the beneficial insects.
