We surveyed 94 greenhouse and nursery growers in three Northeastern states to examine factors that influence integrated pest management adoption. We constructed four alternative dependent variables describing the extent of IPM adoption, and employ Logit, Ordered Logit and Tobit models to identify factors affecting IPM adoption. We find that IPM adoption is more likely to occur on large farms that hire more full-time workers, and have more diversified crops. Greenhouse and nursery operations that face disease problems are less likely to adopt IPM, and availability of biological control agents limits IPM adoption. Our analysis also highlights differences between the self-reported and more objective IPM measures.
