The OHP PGR Calculator takes the guess work out of the equation when it comes to calculating and applying PGRs (Plant Growth Regulants) in the field. The OHP PGR Calculator will allow the user to look up current PGR rates in ppm for spray or drench applications. The grower then enters the desired dose and the size of the application area (L x W) or the number of pots for a drench and the application conveniently calculates the amount of solution and product needed. "A simple tool like this takes the guess work out of PGR applications and calibration. It's easy and accurate," adds Dave Barcel, Senior Technical Manager - OHP, Inc. The OHP PGR Calculator also has the ability to access SDS sheets, Labels and other specific information on different OHP PGR products.
