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.
Segway fungicide: Effects of irrigation on distribution May 2020 On a creeping bentgrass green, both the amount and timing of irrigation following cyazofamid application affected delivery of the fungicide to the target site.
Pesticide phytoremediation by native plants May 2020 Researchers evaluated three commonly used plant species’ capacity to minimize off-target movement of a fungicide, herbicide and insecticide.
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.
Wetting agents: Differences and implications for best use May 2020 Wetting agents vary in their effect on water surface tension, water infiltration and water retention. Researchers evaluated 15 products to help with proper selection.
Classifying fine fescues used on golf courses May 2020 The five fine fescues common in turf systems have key differences. Clarified taxonomic classification can help turf managers better capitalize on each grass’s strengths.
Spent coffee grounds for turfgrass? April 2020 Texas A&M researchers are investigating whether used coffee grounds can rival peat moss as a root-zone amendment.
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?
PGR effects on turf under heat and salt stress April 2020 Researchers tested whether plant growth regulators could improve the health of creeping bentgrass under heat stress, salt stress and the two conditions combined.
PoaCure: Has annual bluegrass finally met its match? April 2020 A turf scientist provides an in-depth look at the herbicide PoaCure, including registration info, research findings, key considerations for successful use, and more.

Bermudagrass: Reducing winter injury, spring dead spot March 2020 Joint projects are exploring solutions to winter-related hybrid bermudagrass woes, including the effects of fall mowing height on turf survival and strategies for combating SDS.
Zoysiagrass seedhead development and suppression March 2020 Go inside in-progress research aimed at creating a model to guide timing of PGR applications for better zoysiagrass seedhead suppression.
Risk thresholds for lance nematodes in turfgrass March 2020 A nematologist takes a close look at the relationship between lance nematodes and turf health, and how nematicides factor in.
When is Poa annua seed most germinable in spring? February 2020 Well-timed collection of clippings can limit the introduction of additional — and potentially herbicide-resistant — seed into the seed bank.
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.
Attracting bats to golf courses February 2020 In the first-ever study of bat activity on golf courses, a wildlife biologist looked at which golfscape habitats these prolific pest predators prefer, revealing ways superintendents can better support them.
Wildflowers bring in beneficial insects February 2020 Incorporating flowering plants on golf courses is a well-known strategy for aiding pollinators, but the practice offers another perk: attracting predatory and parasitic insects for natural pest control.
