AZ Hello

[Pennydt]

Hello from Gilbert, Arizona I’m working on my first above garden adventure. I jumped on here to ask what is wrong with my tomato vine. I figured all you gardeners would know what was wrong with it. (Brown spots on the leaves and yellowing) Any advise? I do not see insects.thanks

Hello and welcome to the Junction @Pennydt. I'm sorry that you are having some problems.

This looks like Early Blight to me. It starts on the lower leaves and works its way up. Remove the diseased foliage and place in the garbage or burn it.

This one is easier to prevent than to cure, but if you treat it you should still get a nice crop. I remove the diseased foliage and then use a spraying program. I will alternate spraying copper and Daconil every week and also if there is rain. This will help to control it.

Welcome to the forum, and sorry to see your problem with the blight. As a prophylactic, I spray my tomatoes (and many other plants) with a mix of Surround and potassium bicarbonate, though I stop the Surround on cherry tomatoes, once they set fruit. The potassium bicarbonate is more of a prophylactic, and copper is more of a cure, though I don't like to spray it to often. Something I use later on, which is another cure for some fungal diseases, is H2O2, which is cheap, and I spray it once a week, later on, a half cup 3%/gal.

Good luck with the garden!

Welcome to the forum! I have struggled with early blight and recommend spraying plants with a copper fungicide when they are babies to stop it from appearing, or at least slow it down. And do trim anything remotely diseased and as Miss S says burn it or get it off the property. Keep the plants well pruned and airy helps too. Plants can come back strong from early blight (don't ask me how I know lol).

Welcome to the Junction! I use H2O2 for early blight and has worked well for me.

Welcome to the Junction from Kentucky. Prune aggressively any infected leaves plus any that you think might become infected. In extreme cases, I will use diluted peroxide in an attempt to control it. MissS is sharp along with a lot of other people on the site. You came to the right place to learn.
