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...
Fungicide use in the turf industry - prevention or cure?
A recent trend in the turf industry has been one of prevention is better than cure and this appears to have been driven by a combination of chemical manufacturers together with their suppliers. I am not arguing that this is an admirable approach and one that could lead to a reduction in some problems developing. However, there are three issues I have with this. Firstly, surely if prevention is better than cure this should be taken literally and not be based entirely on liberal applications of chemicals, on the off chance that it will prevent any potential disease or pest infestation from occurring? Surely you wouldn’t pump antibiotics or other medications into your system on the off chance that you might get an infection, would you? The second issue is one of pure economics. If prevention is better than cure surely the starting point for this is the health and nutrition of the plant (and the soil) rather than a blind reliance on chemicals for this? In the same way, a balanced...
