the dreaded aphid disease

15 years ago

What is the disease carried by the aphids..

Its beginning now: browning leaves will quickly die from the bottom to the top of the plant. It's spread by aphids. I've sprayed with a neem/alcohol/soap solution, and will treat the plant with the copper medicine.

I went through this last year and in the end, lost. Does anyone know what I'm describing?

I would put pictures here but the process confounds me.

    Noticed your in the Atlanta area. Im new to this and do not know the aphid disease. If you have pics you can always email them to someone to post, or you could upload to a free site like flickr or photobucket. After that copy and paste the address to the picture in the box.

    I haven't noticed anything in particular except I may have been overwatering some plants turning leaves to yellow. I disposed of them last night in a ziplock just to be safe. They were still in cups.

    The 15 plants I have out are doing well (except mortgage lifter).

    Let me know if you need help posting pics, I can do it for you. Will be interesting to see how you fair in the same area. I'm in Dacula,GA

    CMV (cucumber mosaic virus) is spread by aphids but doesn't fit your symptoms.

    Upload photos to photobucket, copy the HTML code from beside picture and paste the code in your reply here.

    From the Album page on photobucket you can mouse over the picture and codes will appear under it.

    Posting the pictures of the infected leaves, which have been removed. The tomato is a Mortgage Lifter which was planted one month ago in a 20 gal. container and was sprayed with a Neem solution twice in the past week for aphids. The plant is unhappy now, can it be saved?

    I'm feeling discouraged about the prognosis because I lost the plants last year. Damn the aphids..

    Trying to post the pictures...

    Here is a link that might be useful:

    Bill - it looks more like a soil drainage issue in the container to me...

    Not a disease/virus.

    EG and Jean, excellent insight.. I can do something about the drainage. Thanks.!

    It doesn't particularly look like a drainage issue to me... Looks more akin to fertilizer burn.

    Here is a picture of fertilizer burn for comparison:

    The thing that makes it look like fertilizer burn (or excess salts) to me is that there is some yellowing, tho not much, but the edges of the leaves are browned and crispy - A good indicator for fertilizer burn.

    It could be watering issues, but in my experience excess watering doesn't yield crispy leaves and tends to have a little more yellowing. Also, the soil looks fairly dry, I wouldn't expect that if the mix was retaining too much water / not draining.

    Can you elaborate on your watering / fertilizing schedule?

    there is no such thing as "aphid disease"... aphids can "transmit"and/or spread disease... that indeed looks like fertilizer burn ...

    its a big 20 gal pot holding two bags of potting mix, from LAST year. It has a cap on the bottom which I plan to remove to improve the drainage. It sits outside and catches rain so... The thing is that whatever it is it killed my tomato plant from last year from the same syndrome. But I nursed the tomato and removed foliage to the end.

    If it is excess salt accumulation, can this be corrected?

    You would have to improve drainage drastically and flush the soil thoroughly with water or replace the soil.
