Replication data for: Final report for Neudorff crabgrass trial - Project # G19-07
Borealis
Lyons, Eric M.; Watson, John R. — 2024-09-30 This project compared liquid and dry formulations of Fiesta at varying rates on pre-emergent control of crabgrass and other weeds in a cultivated area of soil. Post-emergent control of crabgrass was also documented. In addition, the study will also provide information to the industry sponsor on product efficacy. Project results may also be used for registration purposes and marketing in the Canadian market.

Replication data for: Comparing plant growth regulators: Anuew, Primo Maxx and an experimental on a USGA putting green
Borealis
Lyons, Eric M.; Flude, Corey; Watson, John R.; Howard, Emily — 2024-10-02 This project evaluated the effect of Anuew (prohexadione-calcium) as compared with industry standard, Primo Maxx (trinexapac-ethyl) and experimental NAI-20026 (trinexepac-ethyl) on turfgrass growth and quality parameters on a mature bentgrass/annual bluegrass greens height stand of turf. Performance was assessed by how the treatments impacted turfgrass growth (clipping biomass), any stress if observed, and associated turfgrass quality measures.

Lyons, Eric M.; Watson, John R.; Howard, Emily — 2024-10-02 This project evaluated the effect of BlackHawk (NUP12130) as compared with industry standards, QuickSilver (carfentrazone-ethyl) and other commercially available surfactants and herbicides. Turfgrass growth and quality parameters on a mature bentgrass/annual bluegrass greens height stand of turf were evaluated, as well as efficacy of the products on moss control.

Replication data for: Comparing different formulations of Fiesta to determine application safety for turfgrass: Project G20-04A+B
Borealis
Lyons, Eric M.; Watson, John R. — 2024-10-16 This study compared liquid and soluble granular formulations of a well-known commercially recognized low-risk herbicide, Fiesta, at varying rates to assess the impacts on turfgrass quality and safety following application. Both projects compared formulations (liquid and soluble granules) of Fiesta at varying rates to determine application safety for turfgrass. Project A examined effects of the products on a 90% turf-type tall fescue/10% Kentucky bluegrass sward of turf. Project B examined effects of the products on a 3-way blend of 100% Kentucky Bluegrass sward of turf. Project results may be used for registration purposes and marketing in the Canadian market.

Replication data for: Comparing the efficacy of different rates of liquid and soluble granular formations of Fiesta on broadleaf weed populations in lawn-height turf
Borealis
Lyons, Eric M.; Watson, John R. — 2024-10-16 This project compared formulations (liquid and soluble granules) of Fiesta at varying rates on broadleaf weed populations common in lawn-height turfgrass. In addition, the study also provides information to the industry sponsor for registration purposes and for use in the Canadian market. To analyze control of weed populations, point quadrat weed counts, NDVI and visual ratings were used throughout the experiment.

Replication data for: Final report for Neudorff Fiesta safety trial– Project # G21-03
Borealis
Lyons, Eric M.; Watson, John R. — 2024-10-29 Applying low risk herbicides on turfgrasses to control weeds and maintain quality is common practice in areas under a cosmetic pesticide ban or reduced herbicide framework. This study compared liquid, soluble granular, and dry formulations of a well known commercially recognized low-risk herbicide, Fiesta, at varying rates to assess the impacts on turfgrass quality and safety following application. Quality of turfgrass was analyzed using point-quadrat counts, visual ratings, and NDVI readings throughout the experiment. The different formulations of Fiesta did not cause any significant turfgrass loss in the experiment. Some phytotoxicity was observed with all the Fiesta products post-application. Any existing black medic weed populations in the treated plots were significantly reduced by all products.

Replication data for: Final report for Neudorff Fiesta efficacy trial – Project # G21-04
Borealis
Lyons, Eric M.; Watson, John R. — 2024-10-30 Low risk herbicides are now commonly used on lawn height turfgrass to manage weeds. This study compared various rates of Fiesta liquid, granular, and soluble granular formulations to determine their effectiveness of controlling broadleaf weed populations on lawn-height turfgrass. To analyze control of weed populations, point-quadrat weed counts, NDVI and visual ratings were used throughout the experiment. There were significant differences in percent control of dandelion at 18DAT1 and 7DAT2 - all treatments provided good control at 7DAT2; this effect was not evident at 14DAT2 and 21DAT2. There were significant differences in percent control of black medic at 14DAT1, 7,14, and 21DAT2; all treatments provided significant control of black medic at 21DAT2.

Replication data for: Efficacy of fungicide products for control of dollar spot on a USGA putting green
Borealis
Lyons, Eric M.; Jordan, Katerina S.; Watson, John R.; Howard, Emily — 2024-10-28 This project evaluated the effect of a Nufarm selective fungicide mixture as compared with common industry standards to control dollar spot (Clarireedia jacksonii, formerly Sclerotinia homeocarpa), and anthracnose (Colletotrichum cereale), if observed. Turfgrass quality parameters on a mature bentgrass/annual bluegrass greens height stand of turf were evaluated, as well as efficacy of the products on disease control.

Replication data for: Final report: G21-02 – Greens height plant growth regulator trial
Borealis
Lyons, Eric M.; Flude, Corey; Watson, John R.; Howard, Emily; Ball, Cassidy — 2024-10-28 This project evaluated the effect of Anuew (prohexadione-calcium) as compared with industry standard, Primo Maxx (trinexapac-ethyl) and experimental NAI-20026 (trinexepac-ethyl) on turfgrass growth and quality parameters on a three-year-old greens height stand of bentgrass turf. Performance was assessed by how the treatments impacted turfgrass growth (clipping biomass), any stress if observed, and associated turfgrass quality measures.

Replication data for: Final report for Neudorff crabgrass trial – Project # G21-05
Borealis
Lyons, Eric M.; Watson, John R. — 2024-11-04 This project compared liquid, soluble granule and granular formulations of Fiesta at varying rates on pre-emergent and post-emergent control of crabgrass and other weeds in a cultivated area of soil. Two industry standard treatments were also included. The study has provided information on product efficacy.

Replication Data for: G18-03 - 2018 Greens height fertility trial
Borealis
Lyons, Eric M.; Watson, John R. — 2024-07-19 This project tested existing formulations of various Brett Young product lines at three different levels of nitrogen application that were split throughout the growing season. The target annual nitrogen rates for the study are 0Kg N/100 m2, 1 Kg N/100 m2 and 2 Kg N/100 m2 from a granular nitrogen source and 0-0.34 Kg N/100 m2 from a liquid nitrogen source. The study also included a 0.5 Kg N/100 m 2 control for comparison with the granular and low nitrogen liquid treatments. The objective of the study is to provide more information on the products for use by the sponsor and Canadian turfgrass industry professionals.

Replication Data for: Plant growth regulation and the rebound effect when prohexadione calcium is applied to fairway height annual bluegrass and creeping bentgrass swards
Borealis
Husiny, Jaber; Ficht, Alexandra; Watson, John R.; Lyons, Eric M. — 2023-03-07 The purpose of this study was to test the effectiveness of prohexadione calcium (PC) as a plant growth regulator (PGR) at different rates on a mixed stand canopy at fairway height under northern temperate conditions using an extended growing degree (GDD) day application schedule. Additionally, this study aimed to capture the rebound effect measured after regulation loss and subsequent applications of PC.
