I am getting a brownish possible fungus (not sure) on my kale and tomato plants. I am unable to identify the problem and wondered if you could help. I have attached photo of problem.

Hi and welcome. Sorry I couldn't see exactly what you are referring to in your picture. Could you give us a closer view, and a shot of the tomatoes as well?

There are some brown burnt looking areas on the leaves but I don't see anything that looks like fungus. As the weather cools you need to scale back on your fertilizer application because the plants are growing more slowly. Too much can cause burnt tips and areas on the leaves.

Things like fungus that affect tomatoes don't normally affect cabbage-y things like kale. But there's an easy home-made fungi remedy you can try that may not help but can't hurt. Spray the foliage of the affected plants with a solution of 1/2tsp. baking soda dissolved in a quart bottle of water. This time of year IS infamous for fungal blights like powdery mildew that definitely do infect tomatoes. So the baking soda spray may prevent an infection even if that's not the problem you are seeing. You can spray it on every few days as a preventative because of course it washes off - I keep a bottle of this in the garden and just spritz it around whenever I'm out there because of course here in FL we have every fungus known to man floating around in the air.
