Grey Leaf Spot?

Gussie · June 22, 2012

Based on my Googling, I am pretty sure I am dealing with Grey Leaf Spot on my Caspian Pink.

Quick Stats: Purchased plant at a local greenhouse. Planted out approx 2.5 weeks ago in Promix (I think this last batch I got was not BX). Earthbox with the auto water system. Espoma Garden Lime and Tomato Tone per EB directions. Planted next to Omar's Lebonese, which shows no signs of illness. Oh, and in case I didn't do something right in my profile, I am in Northern Virginia - Zone 7.

I have attached photos in the hopes (fear?) that you guys can confirm. I just did a foliar spray of Actinovate so I can stop stressing and go to work, but not sure what else I can/should do. Happy to hear any/all advice from you experts who have enabled my rekindled love of tomato growing.

Trying my darndest to stay organic, and my 14 other plants are loving life. Well, except for the Cherokee Purple that I accidentally over de-suckered one day. Poor guy is still trying to figure out how to grow now that I stopped pinching him.

Thanks!

Looks more like Septoria to me, especially on picture #1, or possible Septoria + early blight. Based on the second picture, I wondered if these are just the bottom leaves or if it was spread throughout the plant. Either way, the Actinovate should help, and I would suggest removing the infected leaves. Good luck!

Thanks! It looked like it was more pronounced on the bottom leaves, and it had not (yet?) moved all the way up the plant. If I remember correctly, it's about half way up.

I will remove the remainder of the leaves when I get home, and I will watch it like a hawk. It wouldn't just be stress from the heat wave, would it?

Got home and looked at my plants long and hard. Turns out there are now three affected with this craziness. I do believe you are right with the septoria, rsg, so thank you for giving me the appropriate place to start looking for solutions. I am not seeing lots of organic options for managing the spread, but I will keep searching.
