## Questions & Answers

**Q: It says it is a concentrate but how much spray will this yield?**
A: This one pint (16 ounce) bottle will make 24 gallons of spray.  The normal mixture amount is 2 ounces of Monterey to 3 gallons of water.  IMO it goes a very long way and works very well on cabbage worms.

**Q: An employee at a nursery told us that in addition to spraying the foliage with the dilute product, we could spray this full strength on the ground at**
A: I believe that would be a waste of this product.  It attacks the worm's mouth parts when it is consumed, which shuts down their ability to eat, leading to their demise.  Unless there is material on the ground that the worms are eating, spraying it on the ground would have no effect.

**Q: is the active ingredient Bacillus Thuringiensis Kurstaki ?
Need for tomato horn worms !**
A: BT kills worms.

**Q: Is this organic?**
A: Yes I believe it is as my husband uses it on his plants and he only uses organic products
