It is increasingly commonplace in the turf industry for Managers to try and do the right thing in relation to  monitoring the environmental impact and using lower risk inputs,  whether these  be  for example fungicides or fertilizers .  Gone are the days of the mercuric fungicides! This is an  admirable approach  but a major issue  is that there is little by way of good information on the non - target impact of preventative (or curative for that matter) programmes.   Spraying to manage one disease can in fact encourage other diseases. In 1995 Eric Nelson discussed the  non-target  effects of fungicides in depth. The actual manner in which this disease enhancement occurs depends on the specific environment  in which  applications are made.   The main reason this occur s  is that by spraying to deal with a fungal pathogen, you in turn cause a reduction in  competition from other  non-p athogenic antagonistic microbes. This reduction leads other pathogenic species  to  proliferate  and be

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 die
