Possible late blight?

gryffin · August 20, 2011

I went out earlier this morning to check my plants and found several leaves with possible symptoms of late blight. I've never seen the disease up close and in person, but what I saw seems consistent with pics I've seen online at Cornell's site.

After taking pictures, I doubled bagged all the branches/leaves that appeared to have symptoms, and I'm prepared to pull the rest of the affected plants if it is late blight. Below is a link to a web album with the pictures I took. Fortunately, there are only 4 plants at this location (on my deck in planters). My main tomato plot is at a community garden.

Thanks for any feedback!

Removing affected foliage is a good idea but before you do anything as drastic as pulling the plants, you might want to check these two sites to make sure it isn't something like Gray Mold that can look very similar to LB:
