Where our guidance comes from

Our field calls are grounded in university research and professional standards, then extended by our own documented field positions. The science is the floor.

Jeff Kaulbars on The Morning Blend.

Jeff joined ABC Action News’ Morning Blend to talk about why palms in Florida communities fail, and what proactive palm health care looks like.

Lethal bronzing
The vector research

We lean on the work of Dr. Brian Bahder (UF/IFAS), among the foremost researchers on lethal bronzing and its planthopper vector in Florida.
