Abstract/Contents:"Biostimulants are materials that when applied in small quantities, may promote plant health and growth. Many biostimulants contain cytokinins, seaweed extract, humic acid, or even beneficial microorganisms, all of which have individually been claimed to have a positive effect on plant growth or health. Biostimulants have been used increasingly in recent years, as the EU just recently announced in the winter of the 2019 that they would treat biostimulants as their own separate entity under fertilizer regulation. The US has no such regulation for biostimulants, therefore, much speculation exists as to the product integrity being marketed and sold in the US. With this in mind, three greenhouse trials were conducted with Tifeagle bermudagrass (Cynodon dactylon) in Clemson, SC during the summer of 2019. Study one was a rooting study performed in lysimeters to determine differences in rooting between treatments. Study two was a recovery study where a small plug was extracted from the main plug to replicate an injured area, and then used to determine the speed of recovery between treatments. Study three was a grow-in study to replicate the speed of the turfgrass to establish in a bare area. Three biostimulants were used for all three studies, each applied individually, and also applied with nitrogen fertilizer. Additionally, an untreated and a fertilizer (0.2 lb N/1,000 ft2) treatment were added for eight total treatments. Initial treatments began on June 21, 2019, and biostimulants were applied biweekly for 12 weeks. Fertilizer was applied opposite biweekly. Ratings and pictures were recorded weekly. A destructive harvest was conducted at study conclusion to determine biomass differences between treatments. Trends and differences will be discussed during the presentation."
