What kind of "leaf spot"?
Out of 200 plants (20 some varieties), this is the only one with some leaf issues. New growth is unaffected as of now. Plant looks healthy. No yellowing.
It is Purple Bumble Bee. When I search images online, it really looks like the ones they show for air pollution like ozone damage. Closest I can guess is Septoria, but the spots are not round or tan. More of a purplish/black and squarish. Very similar to Leaf Scorch on Strawberry leaves. Any specific hunches? IMG_1231.JPG IMG_1230.JPG IMG_1229.JPG These pics did not turn out as clear as I hoped. Will take some more tonight. Last edited by PureHarvest; May 6, 2016 at 08:04 AM. |

No yellow halo around the lesions. No curling or distortion, no mottled or mosaic pattern. Might be bacterial. Copper spray will most likely cover it.

I agree, definitely not Septoria.. Looks bacterial to me as well. Remove damaged foliage, isolate from others if possible.. You can try copper, sulfur, or diluted bleach spray.. Bacterial diseases are extremely difficult to correct if they are allowed to flourish. Good luck!

I might just trash the whole bag. It is only one of 100 bags, so not worth keeping around for the innoculum. That and it's a cherry, which I don't really grow a lot of anyway. More for my MIL who likes them. I still have two other bags with PBB cherry, so she won't go without...

Consider Tomato Spotted Wilt Virus too. I'd ditch the plant. Thrips can spread it.

I might have to isolate and spray first before trashing completely. Just to see if something takes care of it. Seems it would start showing on other plants but being the only one and only one of that type.
Could it have come from the seeds.? |

All my plants are protected from rain via my high tunnel, so I don't know how it got on the one plant, whatever the offender is.
I guess a seed-born problem could have caused this. It is still too cold and early for thrips and most other bugs up to this point, but their feet and mouths could spread it later, so I am tossing it. I could spray, but I hate spraying. I have never had leaf issues ever this early in the year, and I don't want to have a plant hanging around with inoculum while the rest of my crop is trying to take off. Besides, it's not like spraying it will magically cure the plant or eliminate all spores etc. I will be doing some detailed inspection on everyone tomorrow now that the weekend is here. We just need some sun, ughhhh! |
