New PGR Resources
Here’s a listing of new information about PGRs
For plant growth regulator information, greenhouse growers have a number of online and electronic information sources available. This post highlights some of the latest information about PGRs utilized for ornamental crops.
e-GRO Mobile Rate App
This spring, a new web-based app was introduced by the e-GRO group. The PGR Advisor for Floral Crops lists crop specific recommended PGR rates based on the labels, research study rates, and plant supplier information. It can be accessed using your phone, tablet or computer. The app is free.
The web address is: http://www.egro.mobi
After starting the app, then select the plant you want to treat, and decide among the PGR options listed.

PGR Mix Master
Brian Krug of the University of New Hampshire partnered with Fine Americas to develop a mobile app for calculating PGR mixing rates. PGR Mix Master is available for the iPhone®, Android®, and Blackberry®. It calculates PGR mixing rates for sprays and drenches for most of the common chemicals available for ornamentals. A more detailed article about the apps was written by Dr. Krug as an e-GRO Alert. The article also has an embedded video with instructions about how to use the app. The article is number 1.11 and is available at: http://www.e-gro.org/alert.php
(A computer based alternative rate calculator called PGRCalc is also available calculating mixing rates at: http://extension.unh.edu/Agric/AGGHFL/growing_tools.htm)
Podcasts
A collection of 20 podcasts (videos) that cover a wide array of PGR related subjects is available free on the Greenhouse Grower website. Most videos are around 5 minutes in length.
