We have been having hot and humid days with no rain for 3 weeks (it just rained 6 inches this weekend, so I'm watching for some recovery). Lawns are KBG, fescue and rye. Many lawns in my area, fertilized or unfertilized have this issue going on. The affected areas are in the sun and the unaffected areas are green which are in the shade. The lawns that are irrigated look much better. My question is CAN THIS BE JUST DORMANCY? So many times people just jump in a spray a fungicide and/or apply Dylox. On my treated lawns I've used Merit so its not grubs. The grass does not pull up when tugged. This is my lawn. I haven't mowed in 3 weeks, been so dry. This is the first year I haven't watered. I've applied 1/2 lb of N in April and 3/4 lb in mid June with Merit.
