## Questions & Answers

**Q: What is active ingredient**
A: it's on the label

**Q: How does this work on brown blight?**
A: Used as a mold preventative.

**Q: Will this kill pm ifs it’s already present?**
A: I use it as a preventative for PM.  I will tell you this would be the closest bet besides Labs(lactic acid bacteria serum) for killing PM.  Don't waste your money on anything else. It does not work! Get this, treat pm, save for future use...look into making Labs and use labs and Regalia to prevent PM.... An ounce of prevention is worth a pound of cure🙂

**Q: Is a wetting agent needed? Can it be used as drench and foliar on the same day, in 7 day intervals?**
A: Yes is the answer to each of these questions. 
Great product.
