Central Jersey, zone 7a. I've observed dollar spot now for a 3rd consecutive year. To my knowledge I never had it prior to the 2020 growing season, though I've also become much more observant over the years and know to be on the lookout for fungal issues.
The first year (2020), I just let it ride, and tried (unsuccessfully) to fertilize and grow my way out of the problem. It did not work. I had small patches of dead turf / bald spots all over the place by the end of Summer.
Last year (2021), I reluctantly sprayed the bayer fungus hose end product (propiconazole) at the curative rate after dollar spot became evident (early-mid June). Fortunately, it worked. I didn't even have to do a second application, it completely wiped out the infestation in one application. I was thrilled.
My hope entering this year (2022) was that it would not return since I had such good success treating it last year, however, I started observing the typical small patches right around the first week of June. I just yesterday applied the bayer propiconazole hose end sprayer product to combat the issue and I am hoping for results like last year.
That being said, I am paranoid about building up resistance to propiconazole, so I wanted to ask what I can rotate the propiconazole treatments with in the future if I have to spray again this year or in the future. As an example, my understanding is azoxystrobin - does not - work for dollar spot. I'd like to know what brands of products you recommend / have had success with against dollar spot in the past.
I was reluctant to preemptively spray, but I'm beginning to accept it will need to be done on an annual basis moving forward. My rationale is, I can't have an outbreak of DS ruin all the hard work in an otherwise healthy turf stand. I just want to do the treatments in the safest / recommended best practice moving forward.
