Abstract/Contents:"Kentucky bluegrass (KB) is one of the most common turfgrass species for golf course fairway in the cool climate. However, it is sensitive to drought. Plant growth-promoting microorganisms (PGPMs) have shown the capability to improve stress tolerance, including drought, in field crops. In turfgrass, fungal endophytes, such as Acremonium, enhance performance and stress tolerance in perennial ryegrass, tall fescue, and fine fescues due to high host specificity. However, the effects of PGPMs on other important turfgrass species, such as KB that rarely forms symbiotic relationship with PGPMs, is largely unknown. The objective of this research was to determine the efficacy of six commercial PGPM products ('BontaniGard 22WP', 'Companion', 'Molt-X', 'Nortica 10WP', 'RootShield PLUS+WP', and 'Serenade') on drought tolerance of KB fairway. A plot with no PGPM application was included as the control treatment. A fairway with 'Kenblue', 'Waterworks', and 'Barserati' KB were established in fall, 2020. PGPMs were applied once every other week, except RootShield (once monthly) from late June to mid Sept. in 2021 and 2022 when irrigation was withheld. Turf quality and growth and stress indices collected with a radio spectrometer. Drought tolerance decreased in the following order, 'Waterworks' ā‰„ 'Barserati' > 'Kenblue'. Differences in PGPMs were observed occasionally in 2022 in which Molt-X was relatively less effective than other treatments. Overall cultivar played a more important role than PGPMs in KB fairway drought management."
