Biological Control of Pests in Forest Nurseries
Most major insect pests have developed resistance to the pesticides now available and new pesticides are facing increased costs and legislated restrictions. These, coupled with increased worker and consumer health concerns and possibilities of environmental contamination, have resulted in increased interest in biological pest control applications. The term biological control as used here refers to the use of living organisms to control plant pests. This is a very active and growing area and is being applied in increasing numbers of commercial applications in North America and Europe. The following programs have been developed in North America and Europe to use biological control agents to limit many common pests found in nurseries, Integrated pest management using biological control requires knowledge of the pest life cycle, careful monitoring to determine pest threshold levels, modification of spray programs to avoid harm to the biocontrol agent and a slightly different way of thinking about insect pests, parasites and predators. The rewards are better pest control, healthier plants, lower pesticide inventories, reduced health and environmental hazards and happier employees.
