White powdery matereial on stems
of pepper plant and basil. Now all my young tomatoes (home germinated and Laurel's) are showing something that looks like curly top- top leaves are curled into small cups and growth is poor. No purple veins, no fungal-appearing spots on leaves, no other colors or discoloration.
I cleared out the infested pepper and basil but still have this severe problem on virtually all plants. Until this, have never had a disease problem. All plants in 15 gal containers, watering by drip system at soil level.. Help appreciated. Fred

Have you checked with a hand lens to see if they aren't mealy bugs?
You might want to take a sample to your University Coop Extension Service for diagnosis. My tomato plants also had a white fungal growth on the stem near the soil-line. The symptoms appeared to match descriptions of Sclerotinia sclerotiorum, but it's quite hot here, so didn't fit the profile that this occurs in cool weather. The plants stopped drinking water, wilted and died. http://www.ext.vt.edu/pubs/plantdise...2/450-712.html http://www.ext.nodak.edu/extpubs/pla...rop/pp659w.htm http://www.ces.ncsu.edu/depts/pp/notes/oldnotes/vg4.htm http://aggie-horticulture.tamu.edu/t...stems/24a.html |

Robin, Thank you for those links. That seems more likely to be what killed my plants.

Oh, I'm so sorry to hear that; honu!
Did they all die? What actions are you taking for next time? Curious....

Thanks Robin,
Every single tomato plant on one side of the house got hit, wilted and dead within a few days, one after the other. Adjacent peppers and herbs were unaffected. Strangely they were all in pots that were sterilized, with brand new potting mix & purchased compost, getting drip irrigation, with red plastic mulch over. I even added mycorrhizal fungus innoculant as insurance. I now wonder if the addition of purchased compost to these pots could have been part of the problem. Fortunately I have about 14 still alive in pots on a different side of the house that is practically all concrete and hardly any exposed soil, but struggling w/ spidermite infestation (if not one thing, it's another). I'm really not sure what to do for next time, since our year round, warm, humid, moist climate is perfect for breeding fungus. Your literature links and suggestion of Southern Blight were very helpful, so thank you very much for sharing! |

honu,
Maybe you can use these links: spider mites Integrated Pest Management (IPM) SPIDER MITE CONTROL This article is about SPIDER MITE control. It will explain why they are a pest and what needs to be done for controlling infestations.
