Dipel , also known as Bacillus Thurigensis Kurstaki . I find it easier
to get a uniform application using dust and a small hand pump duster . I
use the same unit to apply DE - the thing is that if DE gets wet it
loses effectiveness and must be re-applied . We get heavy dew here
almost daily this time of year ...
i don't see many bugs on the tomatoes i want to
discourage. i much prefer to not cause problems
by spraying anything if i can help it. so far so
good.

Â* I take exception to a caterpillar/worm that eats all the foliage -
and green tomatoes - off my tomato plants . I've been plucking and
stomping , but as much fun as that is it gets old after a while . BtK is
harmful only to certain caterpillar-type pests . DE will also affect
pollinators , which is one of the reasons I don't often use it . I'm
VERY careful with what I use and when , I'd hate to poison my bees .
