Rooting Hormones for Plants

Have you ever wondered what type of rooting hormone to use on certain plants and then how do you mix it at the proper rate.  I remember when I started propagating plants everyone would use technical grade rooting hormones from chemical manufacturers.  These however are not labeled for nursery use.  So where do you get rooting hormones, what kind to you use that are labeled for nursery use, and how do you mix them to the right amount.  Here is a great publication from Cheryl Boyer, J. J. Griffin, B. M. Morales, and Eugene Blythe entitled "Use of Root-Promoting Products for Vegetative Propagation of Nursery Crops"  Here is the link:  http://www.ksre.ksu.edu/bookstore/pubs/MF3105.pdf
