Evaluating the use of flower strips in a biological and integrated pest control program at an ornamental nursery

Description

As part of an integrated pest control program, the company Les Serres Rosaire Pion & fils launched an innovative project on the use of flower strips in potted perennial production. A section of a single species of perennial sensitive to thrips damage (e.g., Hemerocallis Stella de Oro) was selected. Large containers of plant media measuring about 1 ft. by 5 ft. were seeded with plant species that attract natural enemies of thrips (especially the predatory bug Orius) such as certain species in the Aster family (e.g. calendula). A bed of the same perennial, located at least 50 m away, served as a control (without flower strips).

Objective(s)

• Evaluate how well containerized flower strips attract natural enemies of thrips
• Keep pest populations on potted perennials below the economic injury threshold and reduce pesticide use
