- My experience with aphids in the open has been that
- around the time I start noticing them, ladybugs start
- noticing them too and within a week they are mostly
- gone. However if you spray, you will kill the ladybugs
- and the aphids will be back in a week. Aphids
- can be physically hassled by a strong stream of water
- from a hose. You can knock the majority off into the mud
- and only a few will survive. This also works on
- spider mites.
- Tomato fruitworms are susceptible to BT (Bacillus Thuringistis
- or something like that). This is a disease that paralyzes
- their digestive system and kills them in a day or so.
- It is sold in garden stores under the name Dipel and other
- names. I occasionally used it to control hornworms and
- various cabbage worms when I was in Florida.
- The tomato fruitworm, cotton bollworm, tobacco budworm and corn
- earworm are all the same insect and it may help if you
- separate your sweet corn and tomatoes. My experience has
- been that old harvested sweet corn harbors a lot of these
- worms and that as the corn dies they move into tomatoes.
- (I've never seen them move the other way). In
- general you will have fewer bugs if you keep your garden
- clean; old exhausted plants often have a disproportionate number
- of bugs.
- I had a lot of trouble with stink bugs and squash
- bugs in FL. I never found a satisfactory organic control
- and was unwilling to spray.
