Question of the Week – Macrophoma Rot

Posted by romeethredge on August 19, 2015

Last week I had a photo of a muscadine with a spot on it. We get several disease caused spots on muscadines and some caused by insects. This one is Macrophoma rot and it can occur worse during rainy times and seems to be worse on certain varieties.  Fungicide sprays early in the season go a long way towards helping have a good muscadine harvest. Agent Mark Crosby wrote a good article about this you can link to here.

Macrophoma rot (Botryosphaeria dothidea) causes small, sunken, black fruit spots that are round with distinct edges in the early part of the season. As harvest approaches, these spots may develop a greasy-looking soft rot around the initial lesion. A halo develops around the black spot and the entire fruit may rot just before harvest. Infections are sometimes not visible until the soft rot stage occurs.

This week I was asked to identify weeds for folks and I got one weed twice in the same week. So I’ll make it the question of the week. What is this plant?

And the Bonus question: What is the song about it, or at least it’s mentioned in the song?IMG_0552
