Wetting agent longevity

The application of H2Pro TriSmart at both monthly (10L/ha) and bi-monthly (20L/ha) significantly (P<0.05) increased mean visual turf quality over the control on 5 of 13 measurement occasions (figure 1).

Both applications of TriSmart also increased VMC% in the rootzone during periods of dryness and drought stress, with 5 occasions being significantly different (P<0.05) to the control at 3.8cm, and 3 occasions at 7.6 cm (figure 2 and 3).

This demonstrates the ability of applications of H2Pro TriSmart to maintain a higher VMC% of the rootzone during periods of dryness and so potentially improve plant health and performance.

Comparisons between the two H2Pro TriSmart programmes in place illustrate that at no time is there a significant difference between the monthly and bi-monthly programme for mean visual turf quality or mean VMC% at 3.8 or 7.6cm.

This suggests that either programme would be acceptable for managing tee or fairway type turf and potentially utilising a bi-monthly programme would reduce resources (fuel and water) used and operator hours to make a considerable club saving and contribute to a reduction in carbon emissions.
