    I think my potted veggies have flea beetles. Anyone know if any organic way of dealing with them?

    Try this homemade spray to control the flea beetles:
    2 cups rubbing alcohol,
    5 cups water
    1 tablespoon liquid soap

    You could also try dusting the affected plants with talcum powder (non scented) it helps repel flea beetles on tomatoes, potatoes, peppers and other plants.

    Cayuga, Eileen's spray works really well. It needs to be re-applied after a rain. Make sure you use liquid soap, not detergent. This spray works on almost all soft-bodied insects, so your ladybugs are safe!

    Be careful spraying when there's bees around do it in the evening when they've gone for the night.

    This is the damage. Does it look like flea beetle damage? I did see one teeny tiny black beetle on the leaves. PXL_20210606_110937979.MP_compress62.jpg PXL_20210606_110947503.MP_compress85.jpg

    no. that doesn't look like flea beetle damage to me. nor have I ever seen flea beetle on tomatoes. eggplant, potatoes, things with thick sturdy leaves but not tomatoes. that actually looks more like environmental damage such as too hot of water being sprayed on the foliage when first running the "solar warmed" hose. pick those leaves off and put them in the trash. don't compost them or leave them on the ground... just incase it is a fungal or viral issue.

    It isn't only fungal diseases that must be fought to protect crops and plant health. Pests don't give rest to cultivated plants either. Aphids, onion and carrot flies, Colorado beetles - this is not a complete list of insects eager to eat cultural plants. In addition, they are carriers of fungal spores from one plant to another. So combating them must be practical and include agronomic measures and pest control products https://www.growgardener.com/best-rear-tine-tiller-reviews/. Use only healthy seed and planting material.

    I think it looks as if your plants have one of the tomato viruses. If this is the case, the plants need to be burned, and all tools and surroundings treated with a disinfectant - a weak bleach solution would do.

    I think that they're just old leaves and nothing to worry about. Are they just on the bottom of the plants?
    If it's blight it would effect the stems as well.

    I don't think blight and mosaic virusus are the same thing Logan. I think mosaic viruses (there are a few) are caused by transmission from infected tools, or aphids spreading the disease, and I believe that tomatoes are also not very happy with chemical insecticides - they can cause the plants more trouble than help. I hope someone will correct me if I'm wrong but I think that blight has to do with climatic conditions. :confused:

    Yes it could be a virus of some kind.
