The Impact of Climate Change on Weed Management There is a direct link between Climate Change and Turf Weeds which have serious implications on turf management in Australia. Climate Change is going to affect herbicide efficacy and weed distribution. Weed distribution will be affected due to the impact it will have on many plant functions of turf weeds. Being highly adaptable weeds will undoubtedly adapt to these changes, and this will raise a completely new set of management issues. Increasing CO₂, together with higher temperatures and variable moisture conditions, will affect the growth and geographical presence of turf weeds, and alsothe efficacy of herbicides that you use to control them. C3 vs C4 plants. C3 turf weeds will benefit from rising CO₂ levels, but studies suggest, that rising temperatures will negate the beneficial effects of CO₂ on photosynthesis. Once temperature go over 25°C, this negatively impacts C3 plants because their photorespiration rate increases. Photosynthes...

Turfgrass Management for out of Season Events
How Off Season Events Affect Turfgrass. As turf agronomists we are constantly trying to offer our clients the best solutions to sports ground management problems. Not only do we offer the latest in product innovations we also strive to create solutions to common issues. One of these is the Increasing use of venues in Australia for are traditionally regarded as ‘’off season’’ use. Concerts, moto cross and even large scale theatrical productions are now more the norm than the unusual. This, coupled with the greater use from more traditional sports such as Rugby League, Rugby Union and soccer mean that the playing surface has come under increased pressure. TV is an unforgiving mistress. Many of these events are televised and have come under an unprecedented level of scrutiny from many ‘’arm chair’’ experts. Is it possible that we are at a point where the demands on these surfaces has reached a tip off point? One where recovery is not going to occur due to pressu...
How do I keep my turf green over winter?
Turf managers commonly use turf pigment and colorants for improving the appearance of sports turf areas. These are cheaper than oversowing, without the issues of removing an overseeded grass from warm-season turf. The use of pigments also occurs in fungicides for promoting plant health benefits e.g Bayer with their Stressgard® technology . Available pigments include Vertmax® , Vertmax Duo® , Green Pig®, Sensi-Pro®, and BASF ‘s Vision Pro®. These are based on copper phthalocyanine with variations in active concentration affecting their rates of application. To better understand how these products perform, numerous studies have been carried out at North Carolina State University and more recently in Sydney, Australia by Gilba Solutions. Why use turf pigment? These offer a viable low-cost alternative to overseeding warm-season grasses. Drought-resistant cool-season grass varieties used for overseeding have made spring transition more difficult. Pigments also ...
