Verdure: Pseudo dollar spot control? June 2020 Purdue University researchers designed field experiments to test the impact of the biological control agent Tx-1 on dollar spot and brown patch activity in fairways.
Verdure: For your age, you look fabulous May 2020 In a series of studies over four years, researchers examined how N and K fertilization should be adjusted on aging ultradwarf bermudagrass greens.
Verdure: Primo your way to reduced nitrogen fertilizer April 2020 Can applications of trinexapac-ethyl — the active ingredient in Primo Maxx — decrease putting greens’ nitrogen requirements without compromising turf quality?
Verdure: Winter applications for spring Poa annua seedhead suppression? March 2020 A turf scientist tested whether earlier applications of PGRs could deliver better control of annual bluegrass seedheads.
Verdure: How long are you going to hang around? February 2020 University of Illinois researchers examined foliar retention and foliar retention efficiency to help optimize retention of a foliar spray on a turfgrass leaf.
Verdure: The way-back article for 2020 January 2020 Research published in 1962 on bermudagrass’s response to varying light intensity still offers pertinent insight on turfgrass light requirements and cutting heights.
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.
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.
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.
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.
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.
Verdure: Organic matter matters July 2019 The age of a putting green affects its rate of soil organic matter accumulation.
Verdure: That’s a sappy relationship June 2019 Can different in-field plant measurements — a clipping sap test or handheld reflectance meters — be used assess turf’s foliar nitrogen status to minimize anthracnose?
Verdure: It’s all in the delivery May 2019 Granular vs. foliar fertilizers — researchers tested them alone and in combination to determine their effects on turfgrass quality and soil nutrient levels.
Verdure: Before growing degree days were cool April 2019 GDDs have become a popular tool for the modern-day superintendent, but the concept first cropped up in turf management about 25 years ago.
Verdure: Jim Beard on the benefits of turfgrass March 2019 A paper from the late Jim Beard, Ph.D., compiled the many merits of turfgrass as documented by scientific studies. The collection remains relevant decades later.
Verdure: Let’s go organic February 2019 A fresh look at the findings from one of the rare studies on organic turfgrass management.
Verdure: Ironing your Poa annua? January 2019 Virginia Tech researchers studied iron sulfate in combination with PGRs for Poa suppression on a creeping bentgrass green.
Verdure: T is for turfgrass, and P is for Poa December 2018 Auburn University researchers evaluated the effects of phosphorus on Poa annua growth and seedhead production.
