PGRs in Agriculture
PGR - It's an acronym farmers are hearing more and more about, but what are they and how should they be used? PGR stands for Plant Growth Regulator. PGRs are often known as plant hormones (also called phytohormones). They are signaling molecules produced within plants that occur in extremely low concentrations. Plant hormones control all aspects of growth and development from initiation of germination to production of seed and fruit to final plant maturity.
In perfect conditions, plants create all the hormones they need on their own. But, anything that stresses a plant can cause the ratios of phytohormones to get out of balance causing the plant to use valuable energy to correct this imbalance instead of building yield. There are five major hormone families in plants: auxins, gibberellins, cytokinin, ethylene, and abscisic acid. Having the optimum ratio of these hormones active in plants is critical to maximizing yield potential in your crops. Stoller has conducted extensive research over the past 49 years to gain an understanding of hormone activity in plants.
Stoller's research found the optimum ratios of the three major hormone groups required for maximum plant growth (cytokinin, auxin and gibberellin). This, along with an understanding of the need for specific plant nutrients in combination with these plant hormones at critical growth stages, is what led to the development of a season-long approach to optimizing plant growth and helping farmers maximize the yield potential of their crops.
One of the biggest yield limiters your crops face on a daily basis is weather stress. Bio-Forge Advanced is a specialized, non-PGR product that helps fight abiotic (weather-related) crop stress. Proper plant nutrition is also important to prevent yield loss. Harvest More Urea Mate is a specialized foliar or irrigation applied fertilizer that contains 11 critical nutrients for optimum growth.
Not all PGRs are created equal. Using the right product with the right ingredients at the right rate and right crop stage is very important. Your Stoller representative can help you utilize these products properly. Stoller has almost 50 years' experience working with farmers to help them build better plants using proven products backed by extensive global research. Stoller products can be used in combination with your current production practices.
