Is this Blight or Insect damage?

15 years ago

I live in Lower Hudson Valley in NY. I put out Toms in May (from mastergardener sale) that are going gangbusters. I put out 2 more in June (from Bonnies via Kmart) and they were looking good until I did a close inspection this AM. pictures are below. first three pics are plant #1 and the 4th is plant #2 right next to the first. This garden is brand new this year so nothing has been planted before. I sprayed Fung-onil when I planted out but not again since. And it was an old bottle. at least 3 years and maybe 4. It has been rainy (at times serious downpours) this past week.

PLease help advise what to do here. I'll pull it if necessary. The next row over has the other toms and on the other side are peppers. A spreading infection would not make me happy......

PLant #1

PLant #2 just starting to show signs

thanks

I can't enlarge the pics enough to see if those actually holes or black mold/bacteria spots. If it is bacterial spot then it will disappear as the moisture/humidity levels drop. Increase sun exposure as much as possible, even with a bit of pruning is necessary. Or you can spray with one of the anti-bacterial, anti-fungal sprays available.

If they are holes, then it is insect pests of some kind and no real threat to the plant.

To me, some of it looks like insect damage, and the third picture down looks like it could be Early Blight or some kind of bacterial spotting, or septoria leaf spot. The lesions look a bit small for EB to be honest. It's hard for me to say what it is exactly.

Here's a link to a website that can help you make a more detailed diagnosis:

Also, here's a link to a recently posted discussion on treatment for EB/Septoria (if that turns out to be your issue): http://forums.gardenweb.com/forums/load/tomato/msg06225646932.html?10

Hope that helps,

So I went all Mr Miyagi on the lower leaves of the affected toms. then mulched heavily. i use soaker hoses on timer for irrigation. Lets see what we shall see. I also sprayed with the Bonide organic 3 in 1 stuff. probably wont change a thing but i did it anyway....LOL

Sorry about the double post. I'm still getting used to the gardenweb system.

Let us know how it turns out.

Peace,
