Dollar Spot

Preventative and curative control

By Scottie Hines, CGCS

It finally looks as if Old Man Winter has left the building…or at least we all hope he has! It seemed like the month of May would never get here, however, here we are, the start of May!

Now is the time to start thinking about spring and summer diseases. It always seems that Dollar Spot is the first of the summer disease to rear its ugly head. Dollar spot is easily controlled and rarely kills Midwest turfgrass but it sure can make things look ugly with the foliar damage associated with it.

For preventative and some curative control of Dollar Spot, Quali-Pro Enclave is an excellent choice!
