Abstract Jack Dibble was one of the UC scientists who built the Kearney Agricultural Center's reputation for first-rank agricultural research. Dibble began his career at UC Berkeley in 1955. Fourteen years later, when the University was establishing the Kearney Ag Center near Parlier, Dibble was reassigned. Though Dibble said he was hesitant at first, “It was the best thing I ever did.” During his 36-year career in entomology, Dibble's work has emphasized the screening of pesticides to determine how much and when to make applications for effective pest control. He also studied application techniques and integrated pest management. Dibble retired in 1991, but is still working on several studies at the Kearney Ag Center.
