I've used BT successfully for years, but it is never something to broadcast. You use it carefully on just what you want to treat. Dipel contains BT.

Products coming to market these days are found to have a concentration of BT in the plants because of how it has been used in some commercial agriculture, so I suspect it will become a hot topic in organic gardening circles.

I often pick the hornworms and toss them into the woods across the road or relocate them to something I don't care about. They can eat all of the datura (jimson weed) they want, I have a fair amount of that. They love it. The hornworms become a great pollinator, the sphinx moth (ironically, it is the tobacco hornworm that attacks my tomatoes, not the tomato hornworm. I've seen other hornworm varieties also, in a yaupon holly). There are a couple of particular predators for the hornworms, a wasp, and the tachinid fly. Here's a blog entry I wrote after finding and photographing one in the garden a couple of years ago. I kind of like these Pillsbury dough boys of the garden - I've written about and photographed them several times.

On the gardening front today, after 56 days over 100 this summer, all it took was one day (Saturday, August 13) of a gentle rain and lower temperatures for several tomatoes to get pollinated in my garden. They may not end up very big, but they're out there! Ordinarily if it isn't below 80^o at night they won't pollinate. We've proved that to be true this year. They won't even respond to the Q-tip approach.
