To answer Raye's question: the odd thing is after pulling all of the smaller tomatoes that had these strange black marks, the
plant actually is producing normal looking small tomatoes. Is this normal?
If that is the case I doubt it is late blight... Late blight is one of the worse. There is no way you can have it and have normal looking tomatoes. Just not possible.
Someone at my office suggested treating with Chlorothalonil
Sometimes I wonder where people come up with this crap....
Here is a product that has that item in it.
Ortho Multi Purpose Fungicide Daconil 2787
plant Disease Control. This is what the MSDS sheet says about this Chlorothalonil as it is part of this product.
Carcinogenicity: MSDS: GENERAL COMMENTS: This product contains chlorothalonil. The carcinogenic potential of technical-grade chlorothalonil (97%) has been tested in two rat studies and one mouse study. It was reported to cause an increased incidence of malignant and/or combined malignant and benign kidney tumors in both sexes in both rat studies and in male mice. In addition, increased incidences of malignant forestomach tumors were observed in both sexes of mice and in female rats in one study. Based on the results of these studies, chlorothalonil has been classified as a B2 carcinogen by the US EPA.
FYI there is no known cure for late blight. Take you tomatoe, some of the leaves and find your county extention office. They will be able to tell you what your problem is.
Sorry I cannot help more. However, I'm real proud you asked about that item before you ate it, or worse fed it to your boy.
