![]() It came into our hands and we started doing tank mixing, field plots. Sanson: SpeedZone came about, the concept, we were very fortunate to obtain the rights to a very unknown chemistry at the time, carfentrazone-ethyl. Golfdom: Let’s talk about SpeedZone herbicide, how far back does it go? How many versions were there? Can you tell me the origin story? I didn’t go by the guidebook it’s more fun to mix things and see what happens. My mother didn’t like it very well when I’d unfold all that on the kitchen table and have burners and everything going. My parents were good about fostering my desire to go into science. Golfdom: You told me a story, about when you were a kid … what was your dream Christmas gift when you were going through the Sears, Roebuck & Co. I pay more attention to the course than the game. That’s in the back of my mind, it should be out of my mind. Sanson: Whenever I get on the golf course, my game suffers because I’m more focused on what the weeds are and how they look the greens and how they look and if they’ve been treated properly with fungicides. Golfdom: When you get out on a golf course and look around, do you wonder what products you’ve formulated that might be making a difference at the course? There’s quite an extensive list but most everything on the (PBI-Gordon) website I’ve touched. Union, Kabuto, Tekken, Pedigree … then, into the summer months you’ve got Surge, and we have Q4, which is patented and has done really well for us. And then when you start getting into fungicide treatments, we have a long list. And then go further down the calendar, another thing PBI is recognized for, is the Trimec brand. Those are applied in the spring and the fall. As you progress through, on the professional side, the one PBI is known for is the SpeedZones. Starting going into spring, the preemergent applications - a lot of weed and feeds that consumers put out that contain dithiopyr, or some of those combos with 2,4-D and some of the phenoxy acids. Sanson: When I’m asked that, I think of the calendar year and work my way through, the timing of the applications help in terms of what we’re looking at. Golfdom: On the golf side, what products have you had your hands on? I learned a lot more of the aspects of formulation and analytical chemistry and just sharpened my skills to help me be successful in a career in formulation science. in organic analytical chemistry and I’ve done post-doctoral studies at Arizona State University. Golfdom: What is your educational background? I wear several hats for PBI but the one I’m known for with your readers is the formulation of products that are in the golf industry, the turf industry, and in particular fungicides, herbicides and insecticides. I’ve seen a lot of changes and a lot of progression. Sanson: I’ve been with PBI-Gordon for a quarter of a century. Tell us about what you do for PBI-Gordon. Golfdom: You know I’m always talking formulation chemistry.
