Things that make tomato leaves and stems twist and curl

Looks like 2-4,D damage to me.

Yeah that's what I thought too. But he specifically said no herbicides used so the link to other possible causes. Of course that doesn't leave out the neighbors use of herbicides.

Dave.

looks exactly like the 2-4D damage I had a few years ago.

2-4D damage,

Damage which is very similar to 2,4=-D also occurs with herbicide carryover in organic matter such as manure, even though composted.

Please see this link: herbicide carryover info

Also do the bio-assay suggested at that link to verify if that's the problem.

I had a few tomato plants that looked exactly like that last year. Of 8 plants in the bed, 3 of them had that problem and the rest were huge and healthy, even though they were only a couple feet away.

It was my first year gardening so I had to buy a couple yards of compost for my new raised beds. I'm not sure if there was something in the compost or if something sprayed on the corn field across the street drifted into my yard, but the plants never really recovered. They continued to grow new twisted leaves and stems, but never set any new fruit.
