What others have said, it you find it you are normally a little behind the 8 ball already. We've had tar spot every year since 2018. With 2018 and 2020 being the worst. You need to be spraying before you see it for the best return from what we have seen. Some years it comes in later but if you are seeing it right at tassel it could get ugly.
