Tomato Blight

It appears here in Long Island we are in the grip of a tomato blight due to the massive amount of rain we have had this year. Its effecting large and small gardeners alike. Lucky for me it hasn't gotten a hold of my tomatoes yet but I'll have to keep an eye on them. Here is some information from the newspaper about Tomato Blight so you can keep an eye on your tomatoes too.


What to look for: White-mold encircled gray spots on leaves and gray or brown lesions on stems. Eventually the fruit exhibits dark, greasy-looking lesions (yuck) and the plants blacken, wilt and die. Since I don't have any (knock on wood) I looked around and found this picture on Illinois Fruit and Vegetable News Website. (click here) Itt



What to do: Affected plants must be tightly sealed in plastic bags and put in the trash. They should never be composted or allowed to linger on the ground.


Preventative: For organic gardens the paper suggests products with fixed copper but states it's the least effective against blight. for non organic it suggests looking for products that contain maneb, mancozeb or chlorothalonil.
