Spring Symposium, Dr. Fred Yelverton, NC State



It’s clear that Dr. Fred isn’t from around here. The accent is like smooth Carolina sweet tea. But the only Tea he’s talking about today has to do with Plant Growth Regulators.

(sorry Dr. Fred. No picture here….we’ve got the room to dark and I don’t wanna be beaten down by using my flash…plus the iphone flash is like…well…a phone flash)

Dr. Fred is working with a lot of PGR timing. And it’s clear that one of the things I’ve been saying about timing is key. Check out this past Zealot Post. Dr. Yelverton is also clearly pointing out the variances in rate having to do with turf type and height of cut. He also has some very good data that says that when you go off the product long enough the “Rebound Effect” is clear and happens and is very real. Point? Go off the material and expect a rebound. So the whole “I can’t sleep because it is summer and I got all superstitious so I quit spraying my PGR” can be a very bad thing.

And going out and making one app is just putting your head in the noose.
