Early bight? - Page 2

barryla61 · June 16, 2014

We went thru and cut each infected limb off of nearly 250 plants and then sprayed with daconil

Puzzling how many people said "yep, that's early blight" without a single sign of ringing or yellow splotches.

While it looks much more like bacterial spot to me, but even I will not commit to any one diagnosis until I've seen more leaves, and/or you've received positive identification from a professional.

Have you considered taking a leaf by your county extension agent? They would be able to identify it. They could also tell you if there have been any other cases of it in your area.

Did that and he said it was early blight

Some extension agents are more adept than others. I agree with Feldon, although I'm trying to remember which disease manifests as rectangular ribbon lesions on the stem? Hmmmm ... seems I should remember that one.

I had a few bottom leaves that were actually touching the ground that looked similar to that. Yesterday I pruned anything close to touching the ground(even non affected leaves) and spray with Bonide copper fungicide from top to bottom. Hope I'm preventing a outbreak. Been reading about the bleach/water spray. Any pros/cons on either application that I should be aware of??? Thanks for any info

I've stopped using fungicides completely, and found that what I'm left with, after necessary pruning, heavy mulching, proper maintenance and selective culling, are lines that will withstand or outgrow the several diseases that are chronic in my garden (Early blight, Septoria leaf spot, and grey mold, mostly).

If you go to the next forum down, Common Garden Diseases, at the very top
of the page you'll see a thread created by Ginger called "Excellent photos/
description PDF of tomato diseases. Click on the link (2nd one) in the first message.

Do you think "Target Spot" (pg 16) resembles your photo?

Just my opinion-I don't think it's Early Blight--I would think you'd have bright yellow around irregular dark spots with some concentric rings for it to be
identified as EB.

Most American counties (called a parish or comté in France, a jurisdiction in most parts of Europe) have an agriculture office that will offer free consulting when presented with diseased plants or questions.

Early blight doesn't always have yellow if caught right away. The purplish/dark markings on the stems is also a sure sign of early blight in my limited experience.

Thank you. I'll try to find out how it is by us.

The county extension agent is a technician paid partially by the state and partially by the county, trained as a horticulturalist at a state university, and whose office assists local farmers, plant nurseries, municipalities, and individual gardeners and home owners with various issues regarding crops, trees, landscaping, lawn grass, garden plants, et cetera.

The county extension agent also usually is the instructor of the Master Gardeners course of study in the county or region to which he or she is assigned. For example, in the State of Indiana, the county extension agent is trained at Purdue University, and instructs the Master Gardeners classes and local chapters under the Purdue Extension program. In Ohio, its done under the authority of the Ohio State University, and so on across the United States.

The individual extension agents vary in their knowledge and talents with regard to teaching classes, identifying diseases, disorders, or instructing farmers and homeowners as to tree pruning, lawn maintenance, pest controls, etc. A homeowner or gardener truly is fortunate when his or her county extension agent is adept at his or her assigned duties.
