Pear IPM

View Print Version

Historical difficulty and recent challenges with pear psylla and mites have sparked interest among growers, consultants, fruit packers, and researchers to take a closer look at the strategies we use to control these pests. Two industry-directed WSU projects focused on integrated pest management of pears began in early 2017.

Louis Nottingham is working with Betsy Beers to evaluate current and novel tactics for managing psylla and mites. Louis is researching the efficacy of insecticides and cultural methods for psylla management such as insect growth regulators, new organic products, tree washing, and plastic mulches.

Chris Strohm is working with Tianna DuPont to assess integrated pest management programs in commercial pear orchards. Chris is scouting for pests and natural enemies in orchards that use conventional, IPM, and organic spray programs. The goal of this work is to create a scorecard to assist growers and consultants with management decisions and reduce the costly spraying that has become the norm for pear psylla control.
