Dr. Zee Ahmed (Clemson University) and Dr. JC Chong (SePRO Corporation) have co-authored a new article in the July 2025 issue of GrowerTalks, offering practical strategies for managing scale insects in nurseries and landscapes.
Key highlights include:
- Identifying the most common scale insects
- Understanding why the crawler stage is the most vulnerable and effective target for control
- Monitoring crawler emergence using sticky bands
- Selecting insecticides that minimize impact on beneficial insects
With over 1,100 species in North America, scale insects are often difficult to detect and manage. This guide helps growers improve treatment timing and reduce long-term infestations.
