My work with prohexadione calcium has been with dry formulations of Apogee or Kudos. There is a product that was released more recently called Cryova PGR marketed by Atticus, LLC. It is also a dry formulation similar to Apogee and Kudos (percent active ingredient.) I have not conducted trials with this product and I don't know the price point. Information on the product can be found at the links below. These items are not the actual label and are promotional.  We are evaluating liquid formulations of both Kudos and Apogee in our research program this year.
