## Description

Bonide Captain Jack's Bacillus Thuringiensis BT, 32 oz Ready-to-Use

Review: Works for powdery mildew - This did a great job getting rid of a nasty bout of powdery mildew. Now that I know that it works I will be using it in the future as a preventative for powdery mildew and I felt it helped keep pests at bay, especially ants lurking on leaves. I truly hate the smell but don't care as long as it does its job. Didn't linger on my produce itself either.
Review: Very effective against hornworms! - This product saved my tomatoes! Hornworms have been bad in Texas this year. I was searching my plants every day for these nasty creatures and going out at night with a blacklight and still having hornworm damage. I started using BT on my plants and overnight found it had killed several hornworms. It is important to me that what I use is non-toxic to pets and beneficial insects. BT does that. The smell is a bit strong, but it dissipates relatively quickly. This is good stuff! I highly recommend it if you're having caterpillar issues in your garden.

## Questions & Answers

**Q: Will this kill squash vine borers?**
A: I've read that it has to be BtK for it to kill SVB

**Q: Amazon's highest rating (4.6) for this type of insecticide, and it is very popular. Do you agree that it is very effective for tomato fruit pests?**
A: Yes it is.  It's hard to find in stores anymore so Amazon is best source.  It works and maintains organic qualities.

**Q: Just curious as to why the info says "Approved for organic gardening" as opposed to simply "organic"! And who approves it?**
A: Because it’s safe to use in a organic garden.

**Q: Will this work on bud worms?**
A: Yes.  You should start using it before you see damage and then regularly every two weeks to keep them from taking over your plants.  Worked great on my supertunias last summer.
