It's all about unlocking the power of Plant Growth Regulators, or PGRs — what they are, how they work, and how to use them profitably. To help us break it all down, we’ve invited Gunther Kreps, a crop science expert from AgXplore, a company known for innovation in biologicals, nutritional's, and crop enhancement technologies. Gunther walks us through what every farmer should know about PGRs, from the science to the field-level strategy.
Plant Growth Regulators (PGRs) with Gunther Kreps of AgXplore. As farmers look for new ways to protect yield and stretch every input dollar, PGRs are rising to the top of the conversation — but what exactly are they, and how do they work?
Gunther kicks things off with a clear breakdown of the science behind PGRs — from naturally occurring hormones like auxins and gibberellins to advanced synthetic formulations used in modern ag. We explore how PGRs stimulate or suppress specific plant responses, helping crops manage stress, increase tillering, strengthen stalks, improve root mass, and ultimately perform better under pressure.
The conversation gets practical as Gunther shares when and how to apply PGRs, which crops respond best, and how to maximize synergy by tank-mixing with fungicides, foliar feeds, or herbicides. He also addresses timing, weather influence, and why not all PGRs are created equal — pointing out the key signs of a high-quality product versus one that might just be snake oil.
We then dive into the evolving PGR landscape, including advancements in targeted formulations, compatibility with precision ag, and what’s on the horizon — like AI-powered prescriptions and biostimulant hybrids.
