Two problems on my tomatoes

bwaynef · June 19, 2013

I've got one plant with some sort of mold growing on it. So far, Daconil hasn't touched it (although, my Daconil is a year old....).

Another plant has some troubled leaves, although growth above these seems to be fine.

Does any of this look familiar?

I think that may be Sclerotinia sclerotiorum (White Mold or Timber Rot)
Daconil doesn't kill fungus, so no surprise that it hasn't touched it. Don't even know if Daconil is a preventive for White Mold.
Maybe someone who has experience with this can help suggesting an effective control.

I used Bill's (b54red) bleach spray on my plants that had these white mold spots. It killed the mold and now they're dry brown spots. The plants are fine now.

it's actually one problem. what kind of weather you had and have there? it should make a set back as soon as temps go over 25C and air humidity drops under 85%.

as for the chemistry, is a fungicide named ''Ronilan'' still available in USA?
also, some info on another kind of mold you may find here, the substances are ok for White Mold too:

I sprayed w/ about 2-4x the strength Bill recommends for bleach spray, and mid-spray realized it and went back and rinsed the plants down 3-4 minutes later. If I don't soon see improvement, I'll try to get the proportions right and spray as recommended.

I added 1 oz. 8.25% bleach to 17 oz. of water.

Paradajz, I'm heading out of town tomorrow for 9 days and won't be able to hunt down those products between now and then.

I'll try to let you guys know how they are when I get back.
