This started as a blackening on the tips of a few leaves and has spread to almost all of my sunflowers. My sunflowers seem to be doing fine even with the spread but for how much longer?

Hi and welcome to NGA @everydayjess

It is rather hard to say "Oh it is...." but, here is a link that describes the diseases Sunflowers are susceptible to. I hope this is of use to you. It has pictures and how to control the problem. Some plant diseases/problems can be regional so it would be beneficial to add at least your state and zone, or country and zone to your profile. To do so, click on the person icon at the top left of the page to access your profile/
