LABServices is a contract research organization (CRO) founded in 1985 to serve the crop-production research and development needs for agriculture in North America. Today we offer a menu of services tailored to the needs of an evolving crop production and pest management industry in agriculture. Located in Hamburg, Pennsylvania (approximately 20 miles west of Allentown, PA), LABServices conducts field R&D studies for product efficacy and crops developed through biotechnology. Agronomic field crops, tree fruit, vegetables and other specialty crops are maintained at the Hamburg facility. In addition to on-site studies, LABServices provides clients project management services to successfully coordinate product development and technical support projects throughout North America.

LABServices also offers clients storage and distribution for experimental and commercially-available crop production products to domestic and international testing locations. A full time IATA- and 49 CFR DOT-certified staff allows this service to efficiently store and distribute sample quantities of crop production and pest management products on an as-needed basis.


The cornerstone of LABServices is our team of skilled professionals.  Our staff of life-science professionals have field R&D expertise in a wide range of biological disciplines: weed science, entomology, agronomy, plant pathology, agriculture, turfgrass, biology, food science, and environmental science.  The LABServices team is uniquely qualified to design studies and interpret results from technical and commercial perspectives, providing the information base needed to make informed business decisions in the plant protection and pest management industries.
