Is the best solution always the best?

Often when we search for solutions to our pest problems we are presented with the best most effective solution. Obviously this is what we would expect, especially when coming from a consultant or expert. No one wants to recommend something that might not really work that good right? Typically the best solution is the one that provides the best control. What if we have other criteria? Doesn't true IPM practices demand alternative actions? Case in point this summer I had a particularly bad outbreak of Cyanobacteria on my putting greens. I did some quick research and the main recommendation I found was to spray cholorthalonil. Great. A simple and relatively cheap solution. The only problem is that I have set some rather stringent EIQ goals for pesticide use. One light application of chlorothalonil would use up half of my yearly budgeted EIQ. I needed another option. Chlorothalonil would only be used in a worst case scenario. I would continue to research options and closely monitor th

"Grow What Grows"

At this time there was very little bentgrass left on my greens. They were almost 100% poa annua. I was in the process of making big changes to my management techniques. The use of a moisture meter allowed me to keep moisture levels controlled during the optimum growing season. I changed over to the MLSN fertility guidelines and my fertilizer rates were changed to be based on the temperature based Growth Potential. I changed the way I mow, cultivate and almost every other aspect of the putting green maintenance. I started using a moisture meter in 2008. All of a sudden I wasn't guessing on soil moisture levels. Although I wasn't precisely controlling moisture similar to how they do on Tour I was able to keep the greens significantly drier. Some people say that in my climate (West Coast of Canada) it is impossible to keep the greens
