Product Trials – Trá sys

Evaluation of Trá sys on High Stress Turfgrass

  • Location: Irish Sportsturf Institute (ISTI), Poaceae Farm, Blessington, Co. Wicklow, Ireland.
  • Date: from July 15th to November 4th 2017.
  • Turfgrass canopy:   predominantly   (>85%)   annual   meadowgrass   (Poa annua) with traces of browntop bentgrass (Agrostis capillaris) and slender creeping red fescue (Festuca rubra literalis).
  • Protection: no pesticides of any type were applied during the trial.
  • Irrigation: it was applied based on wilt assessments – at no stage during the trial was supplementary irrigation required.
  • Equipment: treatments were  made  using  a  CO2  backpack  sprayer (Bellspray R&D JR-203S, R&D Sprayers, Opelusa, LA)

Turf Colour (1-10)

Both  treatments  showed significant differences compared to the control, but  almost  no  difference between the rates.

 

 

 

 

 

 

 

Turf Quality (1-10)

There were significant differences between the  control  and  the Trá sys treatments, with no significant differences between the two rates.

Disease Cover (%)

The  applications  of Trá sys did not completely prevent the  development  of Microdochium  nivale but did reduce it significantly in comparison to the untreated control.

Normalized Difference Vegetation Index (NDVI) (0-0,8)

Treatment 6 rated significantly higher than the control.  Treatment 5 also showed good results.

CONCLUSIONS

  • Trá sys provides a balanced nutrition that improves leaf strength for a healthier plant, with a faster recovery from abiotic stress.
  • Best responses for all the parameters were achieved with the higher rate of 30 l/ha, although the lower rate showed very good results.
  • Due to   weather   conditions,   during   the   month   of   September   the parameters show a negative impact. The results with Trá sys show a great difference in performance.
  • Great results with reduced disease cover over the trial period(-66%), colour (+0,8) and quality (+0,7).
