A tiny caterpillar, sometimes barely visible to the naked eye, is one of the most formidable pests threatening the California brassica industry. The diamondback moth (DBM) is eating its way through California’s heartland. Defeating this elusive adversary will require cunning, innovation and smarter science, primarily in the form of agricultural research.
One such researcher dedicated to helping farmers overcome DBM is the late Dr. John Palumbo, who served the University of Arizona and agricultural community as an entomology professor and extension specialist for 35 years. Internationally recognized as one of the foremost experts in integrated pest management (IPM) for vegetable crops, his work made a profound impact on the fresh produce industry and the critical research needed to defeat DBM.
John’s recent passing reminds us how fortunate we are in this industry to have such dedicated, bright and passionate researchers in fresh produce. For those researchers who find themselves tenured in this fragmented and diverse sector, they devote their lives to a specialized industry often overlooked in mainstream agricultural research agendas. Yet, at this time, we need researchers and support for agricultural research more than ever.
Leaving a Legacy
John’s research not only shaped modern agricultural practices throughout his career but also left a lasting legacy that continues to advance the fresh produce industry. His work inspired innovation, improved crop resilience and ensured food security in the face of environmental and regulatory challenges.
“John was always a strong supporter of ag research, as an advocate for grower needs as well as a trusted, knowledgeable source for efficacy and crop safety data for registration. He will be missed by the research community. We honor his legacy and speak his name in high regard,” said Kari Arnold, PhD.
John’s research looked at new tools and IPM practices to combat DBM infestations, reduce pesticide resistance and identify manageable infestation sources, all while using data and sound science to advocate for growers. However, the example of DBM is only one of many reasons why continued investment in agricultural research is necessary to ensure the sustainability of our industry. As global challenges, such as climate change, the loss of pest control tools and the introduction of new pests intensify, innovative research and technological advancements are essential to support our important producing regions, enhance industry resilience and ensure food security.
Remembering an Industry Legend
“Despite his numerous accolades and prestige, John was one of the most humble, kind human beings I have ever met. Like all of the great researchers I admire, John also had an insatiable curiosity. He was driven by scientific inquiry, always going above and beyond to investigate further, generate additional data and consider other possibilities. I had the privilege of working with John for almost 10 years, and not a day goes by that I don’t reflect on how he’s impacted my personal and professional development, a sentiment that I’m certain is shared by countless individuals in the industry,” said Jeannette Rapicavoli, PhD.
In writing this article, the sentiment I encountered over and over was, what a tremendous honor and blessing it is to have known John as a friend and mentor. He was an absolute gem of a human being—a once-in-a-lifetime kind of person. John was instrumental in the progress and success of fresh produce for the West Coast, overshadowed only by his generous spirit and kindness for all. He will be dearly missed. It is our responsibility as an industry to continue to support agricultural research and continue the legacy of excellence.
