One of my tomato plants looks "burned" similar to a portion of it is dying. Any perception of what this could be? This is one of the Beefsteak tomato plants, I have two of...
This is one of the Beefsteak tomato plants, I have two of them. They're very big, probably 4.75 to 5 foot. And the other day when i checked the garden, a small part of the plant looked dry and unmoving like autumn leaves. I took those leaves off. Then today, I notice that another set of leaves on the plant looked yellow with black on it as if it have actually been burned. The other plant doesn't look approaching this aside from a few yellow leaves on the bottom. Any idea on what this could be from?
Donna is right. Sunburn. Get some shade cloth. You can make a stand over them with PVC next drape the cloth over. If you live in Southern California, right now temps.are 100 and above. Yes they do achieve sunburned and yes even if you water. Byee P.S. Thanks Sandy G. for the site! Could be neomotodes. They are things that eat the roots. Not much you can do presently, but before you plant again, put down black plastic (like trash bags,for a while) afterwards cedar chips when you plant.
Tomato leaves don't get burned by the sun unless you are having regular temperature over 100 and you are forgetting to water. It is more likely to be some sort of fungal disease or blight -- see the sign below. the article also gives you advice more or less controlling the disease. Where do you live? I'm from southwest Missouri and we've been getting tons and tons of rain and adjectives my tomato plants are kinda yellow and look like they're dying. I know mine are similar to that because they've gotten way too much water. My entire garden is suffering because of too much dampen.
Answers: Where do you live? Looks close to it might be late blight.

That is also a sign of verticillium wilt but most plants these days are resistant.
Late blight is a Phytophthora, related to an algae so kind sure that you don't water too much. let the plants dry out between watering's and that may get hold of you by. No cure for Phytophthora's so you might want to plant in another area subsequent year.
too much sun.the sun is burning your plant. If you are watering in the afternoon, this is probably your cause. Watering within the afternoon causes the sun to go directly to the branch, therefore scorching it. If you are not watering in the afternoon try to believe if you have used fertilizer recently, and if you enjoy it may have not been diluted satisfactory causing leaf burn. If not, look on the bottom of the leaves, and check for tiny white insects or "chew marks". Also, if the plant begin to wilt, or is already wilting, you may be in the early stages of bacterial spot within which the laves turn yellow and fall past its sell-by date. If you feel this is the case use an life 3in1 insecticidal soap/ bactericide such as Safer ( I suggested this to another asker earlier!), which is available at Lowe's or other garden centers. Good Luck, and hope your plants bounce back soon!
