Fine fescues on golf courses: Biotic stresses

An overview of the weed, disease and insect pressures that can afflict fine fescues, tolerance differences among taxa, and pest management strategies.

Verdure: You really ought to cover that up

With more transition zone courses opting for ultradwarf bermudagrass greens, researchers investigated various strategies for preventing winter injury of the warm-season grass.

The annual bluegrass seedbank vs. perennial ryegrass establishment

In sites infested with annual bluegrass, researchers tested the effectiveness of various herbicide programs in suppressing the persistent grass while maximizing establishment of perennial ryegrass.

Fine fescues on golf courses: Abiotic stresses

Fine fescues have many strong suits as golf course turf, but also shortcomings. Researchers examine different fine fescues’ responses to traffic, drought, shade, salinity and other stresses.

Seashore paspalum drought tolerance

Fifteen genotypes of seashore paspalum showed a range of responses to drought stress in a recent study.

Verdure: A small dose of manganese for take-all patch

Does manganese’s purported disease-suppressing ability stand up to scientific scrutiny?

Influence of carrier water pH on fungicide efficacy

Fungicides are most often mixed with water before application — can the quality of that water affect a product’s performance?

Fine fescues on golf courses: Availability, establishment, management

Researchers outline proper establishment, mowing and fertility practices for successful use of these low-input grasses throughout the golfscape.

Verdure: Pseudo dollar spot control?

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

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

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

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

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

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?

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

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

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?

A turf scientist provides an in-depth look at the herbicide PoaCure, including registration info, research findings, key considerations for successful use, and more.

Verdure: Winter applications for spring Poa annua seedhead suppression?

A turf scientist tested whether earlier applications of PGRs could deliver better control of annual bluegrass seedheads.

Bermudagrass: Reducing winter injury, spring dead spot

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.
