Terreplex unlocks bound nutrients

Terreplex® is a unique organic acid, derived from lignin with a pH of 2.5 but completely non corrosive and will not burn. Terreplex performs 2 key functions to benefit turf health: 1. Terreplex® dissolves bicarbonates, frees up calcium, magnesium and potassium, and aids removal of unwanted sodium. Therefore an application of Terreplex® before renovation releases nutrients bound up over summer and ensures the turf has fully available access to these key nutrients. Terreplex® provides the opportunity for free calcium to then move onto exchange sites and help with long term soil structure and air flow. 2. Terreplex®, due to its unique organic base, actually… ...Read More

Anthracnose issues?

Anthracnose is a disease common in Poa golf greens throughout summer. It attacks weakened Poa and can lead to turf death. It commonly follows drought stress and is favoured by high humidity.

A recent presentation from Dr John Kaminski of Penn State University highlighted the latest research on Anthracnose control. Key points : Regular, light nitrogen apps equivalent to 1-2 bags Nutrite Bentgrass Soluble per ha monthly is essential. It is actually preferable to apply fertiliser biweekly at 0.5-1 bag. Cutting greens with… ...Read More

A fresh look at turf mites

These days turf mites rate as a major economic pest, and are credited with severe restriction of couch regeneration in Spring!  Mite populations build quickly as new shoots are produced in early spring, providing an inviting food source for this difficult to control pest.  Modern thinking suggests that protecting this early season tissue from mites with a rotation of control products will go a long way to establishing season long control. This year Living Turf's accredited spray service has been busy supplying and applying programmed applications of Thumper® and Higran® (detailed below), with truly astounding results.  Scores of couch sportsfields… ...Read More

Argentine Stem Weevil this summer

In 1986 Michael Gibian completed research on Argentine Stem Weevil (ASW) as part of his BScAgr degree.  Since then the ASW life cycle has been observed during insecticide registration work by various people including Jyri Kaapro and Albie Leggett. In summary we can confirm; Over the past 30 years the period over which ASW poses a threat has widened from about 3 months to 6 months as the climate warms. Egg laying, which used to commence in early September, now starts in July with larvae found at Avondale GC on 5 August after a bifenthrin application. Larvae last for an… ...Read More
