## Description

Southern Ag Thuricide BT Caterpillar Control, 16oz - Pint

Review: Great for catapillars - Thuricide BT works really well if you stay on top of it—meaning you need to respray after it rains. I was able to keep vine borers away for a while, but eventually they got my zucchini plants. As for the bottle size, I actually disagree with those saying it’s small for the price. While it’s not huge, I have a decent-sized garden and it’s lasted all summer with some left over. You only use a small amount, diluted in water—I measure it with a syringe. I also found that using a good pump spray bottle makes a huge difference; coverage improved a ton once I switched application methods. There isn't a noticeable smell and you don't have to wait to harvest like other bug control methods. The catapillars have been absolutely awful this year, so overall, this is effective and economical if applied correctly.
Review: Thuricide Caterpillar Control - Killed the caterpillars on our tomato plants this past summer dead in their tracks!!!! It turned them black but didn't hurt the tomato's at all. This stuff saved our plants and we only applied it once. Still have plenty for next year.

## Questions & Answers

**Q: If i have cabbage aphids on my broccoli plants and i have sprayed bt, will it kill the aphids when they eat the leaves?**
A: All 4 of the current answers are nonsense.  It kills caterpillars and worms and the moth or butterfly eggs which produce the caterpillars.  It is harmlees to other types of insects and harmless to humans.  You CAN spray this on edible vegetables.  It is a bacteria and no more harmful to humans than acidophilus in yogurt.  Search [organic spray for aphids].  I found a product called Organicide which is safe for bees, ladybugs (they eat aphids) and butterflys.  It contains SESAME OIL as its active ingredient.  Neem oil will control aphids and many other pests, molds, mildews and other fungi.  However, Neem Oil has a nasty taste and smell.  I wouldn't recommend spraying the actual florettes.

**Q: Can this product be used as preventative measure and how often? Thank you!**
A: Thuricide is based on a bacteria (or group of bacteria) that infect a variety of caterpillars.   It takes 4 days for the caterpillars to die from the caterpillar, so reapplying less than 4 days is a waste.

This is my 1st year with Thuricide.  I found one large Tabacco Hook Worm on tomatoes.  Applied Thuricide and never saw any more, live or dead.  I applied more about 10 days later (there was a break in the daily rain), and again in about another 14 days.  Never saw more caterpillars.  So I quit applications.

Just my observations.  Not a study.

**Q: does it kill beneficial bugs and worms**
A: It kills caterpillars,  some caterpillars grow up to be beautiful beneficial butterflies and others crop pest moths.  Spray only on plants
You want to protect and spray carefully.

**Q: will it kill army worms**
A: Yes, it will. It may take up to 4 days after application, and make sure there is no rain or sprinklers to wash it off or you'll have to reapply. The key is to make sure you are applying to the leaves, not necessarily the ground or the army worms. The formula must be on their food source so it can get into their digestive system. It basically kills from the inside out.
