Verdure: Poa management, Nordic style December 2019 Looking to thwart Poa annua invasion on red fescue greens, researchers experimented with blending more competitive grasses into the seed mix.
Velvet vs. creeping: Managing bentgrasses in shade December 2019 Can new cultivars of velvet bentgrass — an oft-overlooked species — be a viable alternative for superintendents struggling with shade stress?
Soil surfactants and fungicide movement in turf November 2019 Fungicides need some assistance reaching the root zone if they are to effectively combat crown and root diseases. How well do various soil surfactants help?
Verdure: So, how late is too late? November 2019 A review of the literature on fall-applied nitrogen presents helpful insights on this common practice for cool-season turf managers, from suitable rate to environmental fate.
Oil spills on turf: Facts and myths November 2019 What happens when hydraulic oil gets on putting greens? A scientific overview that separates fact from folklore.
Suppressing Poa annua seedhead production November 2019 Researchers examined how well different mowing delays pre- and post-application of a plant growth regulator reduced seedhead counts in Poa annua greens.
Sequential-application herbicides for bermudagrass control October 2019 Is a series of herbicide applications necessary for optimal control of bermudagrass? Researchers surveyed different combinations and sequences.
Evaluating fine fescue shade tolerance October 2019 Fine fescues are considered to be among the most shade-tolerant turfgrasses, but how much does tolerance vary among species under greenhouse conditions?
Verdure: It’s resistant October 2019 Annual sedge has become resistant to ALS-inhibiting herbicides. Researchers examined the level of resistance and how it developed.
Poa annua: A plan of action October 2019 A $5.7 million research project is aiming to provide a clearer picture of Poa annua herbicide resistance, establish BMPs for Poa control, and deliver new support tools.
What lies beneath: The microbes at play on golf courses October 2019 Bacteria and fungi strongly influence turf health, and new research takes a close look at their composition in the soil of turfgrass under different management intensities.
A soil surfactant affects distribution of mefenoxam September 2019 Researchers investigated whether pairing mefenoxam with a soil surfactant would increase the fungicide’s downward movement in the soil profile.
Testing for disease in St. Augustinegrass September 2019 The Floratam variety of St. Augustinegrass is extremely susceptible to sugarcane mosaic virus. Researchers worked with growers to ensure disease-free sod.
Verdure: ‘Pre-haps’ you should think about that herbicide application? September 2019 Mississippi State researchers took a close look at how several commonly used pre-emergence herbicides specifically impact the roots of hybrid bermudagrass.
Scalping timing for tall fescue control with glyphosate September 2019 Field studies explored whether the renovation of tall fescue areas could be expedited without compromising herbicide efficacy.
Plant biostimulants: Establishing standards September 2019 Turf scientists offer an overview of biostimulants, Europe’s recently proposed research-based regulations, and key considerations for superintendents when considering a biostimulant.
Shallow soil compaction following fraze mowing August 2019 Can fraze mowing be an alternative to aerification for alleviating surface soil compaction in turf?
Identifying turf drought tolerance with a hydroponic system August 2019 Researchers looked at whether applying water stress to turf in a hydroponic system — instead of in field evaluations — could better screen for drought tolerance characteristics.
Verdure: Bacteria diversity in your putting greens August 2019 A three-year study sought to quantify and identify soil microbial populations in creeping bentgrass and hybrid bermudagrass greens.
Soil solubility of iron fertilizers August 2019 Turf’s different responses to granular versus foliar applications of the same iron source prompted researchers to evaluate the soil solubility of 10 common iron fertilizers on 11 soils.
