You can access a brief description of RIMpro in the blog commentary that I 
posted at on Jan 21.  The blog post 
provides a link to a PDF file that contains a 3-page description of RIMpro 
along with my impressions of the program after evaluating it for two seasons.  

RIMpro is a rather complex program that is not easily described in a short 
document.  If you are like me, you will have difficulty understanding how 
useful it is until you actually use it for a year or two.  It sounds simplistic 
when you you just look at a few printouts, but I found that it was really 
useful for estimating how critical the next predicted wetting period might be 
as we move through the primary apple scab season.  

The RIMpro program has several weaknesses (in my opinion) which are described 
in the PDF file noted above.  The biggest problem is that RIMpro predictions 
for ascospore releases are based on weather forecasts, and the accuracy of the 
4-day or even 2-day weather forecasts in my region in spring has been dismal. 
RIMpro will provide you with an estimate of spore release that is likely to 
occur with rains predicted over the next 4-5 days, but that spore-release 
prediction will jump around as the rains approach because the weather forecasts 
jump around, sometimes in the extreme.  I found RIMpro to be a very useful 
tool, but won’t be a really great tool until weather forecasts become more 

It is possible that in some regions, forecasts are more accurate than in the 
Hudson Valley.  Over the past few years, we seem to frequently be at the 
interface of storms that come up the coast, but then just miss us because we 
are a bit too far north and storms that come across the Great Lakes but then 
just miss us because we are a bit too far south.  As a result, over the past 
five years (roughly) we have gotten frequent predictions for major rain storms 
and spore discharge events during the prebloom period only to have the storms 
muss us completely.  Growers apply fungicides based on the forecasts, but then 
find that those sprays served no purpose because it remains dry.  RIMpro will 
not resolve that kind of problem, but it will tell you what might happen if the 
forecasters get it right.
