Tomato Pests & Diseases

Purple leaves and stem Lesions

13 years ago

My heirloom tomato plants grew spectacularly early on, some up to nine feet. However I had very limited production with many blossoms failing. More recently the plants developed a disease that displays purplish blotches on the leaves and multiple lesions on the stems, including the stems of developing fruit (which, then, donÂt develop). The plants are grown in 31 quart, self watering Earthtainers, two plants per Earthtainer. The soil is a four to one combination of Promix potting mix and Perlite. Two cups of dolomite lime (still got BER) and three cups of Gardentone 3-4-4 vegetable fertilizer were added at planting per the Earthtainer instructions. All of the containers are raised off the ground on a platform and have a black plastic mulch barrier over the top of the soil.

Our county extension horticulturalist is stumped.

If you're going to pull some plants anyway, you could try slicing the "trunk" of the stem vertically. If there is some hard brown material in there you could check out the pictures at: http://vegetablemdonline.ppath.cornell.edu/ Perhaps it might confirm your diagnosis. If it's LB, I believe the best thing is to pull anything that shows disease to try to stop it from spreading to other healthy plants. Linda

It's not at all aromatic. It's a very attractive plant, but I'd like to know what it is!

Echeveria turning purple from the stem out towards the tips of leaves

Not enough draining going on. The top Echeveria you should cut the top off till good flesh is exposed. No brown parts. So the rot doesn't spread to the pup on the side. The Lime and Chile Echeveria is probably a goner from the looks of it. Once that center is rotted there's no turning back. I have had miracles happen;). Don't hold your breath though. Succulents should always be in containers with drainage holes. I'm not saying without the drainage holes it can't be done, but it's more complicated;). Also, adding half perlite or pumice makes all the difference in the world;).
