Brown specks / holes in leaves

[guitar1580]

I planted these Brandywines around 2 weeks ago, sprayed with Fung Onil approx. 1 week ago, since I have had early blight problems in the past. Yesterday morning I noticed brown spots on some of the lower leaves, which become holes on some. I'm thinking something is eating through. Notice how some of the holes elongate.

Earlier today, I sprinkled with some Seven Dust after snapping these pics, to hopefully take care of possible bug life.

Anyone recognize this condition?

Thanks, JT

It may be bacterial spot/speck but I'm no pro at diagnosis. I do know these leaves look similar to a recent condition my tomato leaves had, and a copper fungicide purchased from Home Depot did the trick. I wish you luck.

Look at the last pic on this page if you want a comparison.. The suggest is to pick off the worst leaves and spray with copper fungicide. link

Looks like flea beetle damage to me. Sevin should take care of them.

could you post a photo of the back leaf side, and a bit more clear photo of a leaf which has some necrosis on the margins ( like the leaf from the bottom of the first photo you posted )?
and if you can tell how long it approximately takes for those spots to change the color from the grayish one to brown?

Ha! Ivan has taught me everything I know about fungal/foliage diseases but, so far, he has not given me this lesson. I've personally never seen these symptoms but it is what I would imagine a fungal splash-back to look like. I will leave it to Ivan for the correct diagnosis.

I will say, however, that overuse of Sevin (Carbaryl) will boost any spider mite population you have and I wouldn't recommend using it except in a few specialized cases.

Good luck,
Steve

well, we spent a lot of time talking about this at the other thread, that's why i asked for your help

in my experience this is what a Powdery Mildew looks like at bit lower temps ( or should we call it 'not that high' ) and/or slightly alkaline soils.

Spider mites possible, but I agree with the previous analysis of bacterial speck.

Largely caused by over head watering, thus wet leaves, then leaves not drying by sun and airflow.

A copper spray should help stop the spread and avoid wetting the leaves.

Thanks for the input, folks. I threw the damaged leaves away, so I can't really get more pics at this point.

We have not had much rain in the last week, and I don't wet the plant or leaves when I water. About the only dampness is the morning dew, and it has been fairly hot and dry in the week leading up to me noticing the spots.

We're getting some rain tonight, so I'll check things out in the morning after the sevin dust is washed off, and see if there is any more new spots.
