  • Love Shaddox!

    Really enjoy having this podcast queued up. Dr. Shaddox does a great job of sharing his knowledge (especially with a trained monkey like myself) while still holding my attention.

  • I want to like this podcast.

    Travis speaks like a true professor. Dull and monotone. His sentences start off normal and then he eventually ends them mumbling in a low voice. Maybe it’s just me, but if there is any background noise I can’t understand half of what he’s saying. Grab a good pair of isolation headphones. You’ll need them.

Talking Points

Recent interactions between the hosts and their guests.

S3 E62 Dr. Lee Miller - Turf Fungicide Resistance?
Q: Can the repeated use of Azoxystrobin actually lead to worse dollar spot or leaf spot than if no fungicide had ever been used at all?
No, there is no research indicating that using Azoxystrobin makes it worse, although it does not control dollar spot.
S3 E62 Dr. Lee Miller - Turf Fungicide Resistance?
Q: What is fungicide resistance and how does someone differentiate between resistance and an application error?
Fungicide resistance is a stable change of the pathogen allowing it to overcome fungicide effectiveness. It can be distinguished from application errors by continuous failure of the fungicide despite repeated applications.
S3 E54 The Rise and Fall of University Turfgrass Programs
Q: What can we do to get more young adults involved in Turfgrass and keep the Turfgrass colleges alive?
The faculty members often share their stories about how they got involved, typically through outdoor experiences from their childhood. Today's generation lacks such experiences, making it challenging to engage them in turfgrass science and agriculture.
S3 E27 Tinfoil Turfgrass - How to Apply Iron from Someone Who Knows Nothing About Iron.
Q: How do you determine the amount of fertilizer to use on your lawn?
The best approach is to get a soil test to determine nutrient levels.
