John, Thanks for the reply. That .pdf looks like a really nice resource. I have several species of spiders all over the garden, nothing specifically targeting pinworms. I am pretty sure that the most common variety I have is a yellow sac spider. The spiders may not be helpful with pinworms that have buried themselves inside the plant or fruit, but they do a nice job of killing off the adult moths and random traveling pinworms. The spiders combined with diligent human search and destroy techniques (targeting pinworms with minimal leaf removal) have worked well for my small kitchen garden (~9 tomato plants, ~25 plants overall). -Chris

Perhaps chewed with the culprit long gone?

Definitely not any post emergent herbicides used around here. I have very lush gardens in the back yard where these tomatoes are located and no lawn.....just mulch in the pathways. I live in a rural area with no neighbors and no farms within at least a couple of miles. So there is no possibility of any 2,4-D, although I agree that the damage to these plants certainly does look like the ones I have seen on-line of herbicide damage. This is the first time I have ever used Preen. Trust me....I will never use it again. I have koi ponds and didn't even realize until I put it out that Preen is VERY toxic for fish. Luckily all of my ponds are raised slightly so water can't run off into them from the yard. I am sort of afraid to try flushing the bed too much....it's uphill from one of the ponds and I am a little nervous about the contaminated water running towards the pond even though it's unlikely it could run in. I am usually so much better about reading labels. I can't imagine why I even used this stuff!

Indeed, anthracnose and some cracking (the cracking is not too bad, as long as it doesn't rot badly at the crack it's fine).
