Abstract/Contents:"Poa annua suppression in cool-season putting greens is a perennial challenge in many temperate climates around the world. A nutritional approach, common in the UK and becoming more popular in the US, is frequent use of sulfates of iron (Fe) and ammonium to provide plant nutrition plus gradual rootzone acidification. Acid pH (<5.5) is known to favor desirable Agrostis and Festuca species relative to Poa. Another component of this nutritional approach is to not apply P or K as they are also thought to favor Poa. In the US it is very common also to use repeated applications of the Class B plant growth regulators (PGRs), paclobutrazol or flurprimidol, to selectively injure Poa throughout the growing season. Such practices may be safe and successful in mild maritime climates, but what are the effects in the humid subtropical climate of Virginia? Our objective was to apply very high foliar rates of FeSO4 and determine effects on Poa annua populations in a creeping bentgrass green over time. The Fe treatments were split with a generic seaweed extract or paclobutrazol to determine any additive effects on Poa suppression. FeSO4 rates were 0, 1.22, 2.44, and 4.88 g m-2 applied in 400 L water ha-1 every two weeks from March through November. Plots were split by generic seaweed extract (1.27 mL m-2) or paclobutrazol (22.3% a.i. at 0.16 mL product m-2) on the same application schedule. Nitrogen was supplied to all plots uniformly via ammonium sulfate at 8.8 g N m-2 yr-1. No P or K was applied. Line intersect counts of Poa at study initiation indicated a 45% population within the creeping bentgrass. Following 3 months of treatments, paclobutrazol reduced Poa populations to approximately 10%, without regard to Fe level. One season of treatments resulted in 10 cm depth soil pH reductions from 6.4 to 6.0. The medium FeSO4 rate provided the best visual turfgrass quality, with no treatment causing undue reductions in turfgrass cover to date."
