Q.I Notice Some Black Dust On One Of My Sunflower Plants And I’m Not Sure What It Is.

Zone New York, New York | Anonymous added on August 31, 2021 | Answered

One of the stalks on one of my sunflower plants has what looks like some soil on it but I’m not sure if that’s what it is or if it’s some sort of pest or disease. Can you help me identify it and let me know what to do about it? Pictures are attached. Many thanks.

It looks like, either, soil or insect frass. I don't see any signs of pests or disease, which leads me to believe that it is soil. Gently, blow it off.
