Harrell’s is constantly looking for new and innovative technologies to improve plant quality and promote plant health. We always want to provide you with the most beneficial product for your plant, which sometimes means incorporating new ingredients in different combinations. In the past, our research with Activator has demonstrated that the inclusion of Activator with foliar fertilizer increases turf color relative to foliar fertilizer alone. In search of a way to improve Activator with new technology, we set out to identify the potential benefits of adding salicylic acid (SA) to our Activator formula. To do that, we conducted extensive research with Dr. Xunzhong Zhang of Virginia Tech in the spring of 2019 to explore the plant health benefits of SA and to identify the ideal application rate of SA in combination with Activator.

The results demonstrated an increased effectiveness of spray-mixture applications resulting in improved plant health. Through the research, were able to successfully identify the proper dosage of SA, and we’ve incorporated it into the new Activator + SA. Now you can be sure that when you apply critical chemistries to your turf, they’ll be working every bit as hard as you do. No more wasted product, time, or money from a spray failing to fully absorb into the plant. Call your Harrell’s rep to learn more about how Activator + SA can help you maximize your next spray.
