Re: AZ41 - multi-purpose spray
Benny, last year was a year with low pressure for flreblight as we didn't have any spring rains in our (yours, Joe's, mine) area. With the rains we had this past weekend and also a couple of weeks ago, commercial pear growers in my area have been needing to spray more and I would expect your threat of fireblight in 2009 to be higher than in 2008. I didn't spray any of my trees for anything in 2008 and had very little fireblight or peach leaf curl. The lack of rain obviously wasn't so good for the water supplies for the state, though.
I only have two pear trees left, down from about 800 trees 10 years ago. Fireblight was a major problem, only behind codling moths and low commodity prices.
