Re: [apple-crop] New Technology in Apple Scab and Fire Blight Management

Jon,

Being int he Midwest, I will not be able to attend the Summit. Where can 
we get more information on the RIMpro Cloud Service other than the web 
site, or should we set up an account to learn more?


Thanks!

You can access a brief description of RIMpro in the blog commentary that I 
posted at http://blogs.cornell.edu/plantpathhvl/blog/ 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 
accurate.  

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.

[apple-crop] wind chill

[Arthur Kelly]

Does anyone have a handle on how wind chill relates to fruit bud critical
temps.  We are expecting -11F tonight with a wind chill effect of around
-30 F.

Re: [apple-crop] wind chill

[David A. Rosenberger]

So far as I know, wind chill is pretty much irrelevant when it comes to plants 
and other life forms that are not warm-blooded creatures.  Wind-chilll provides 
an estimate of how we perceive the cold, but the measured temperature on the 
thermometer is still  the temperature experienced by trees.  Winds can affect 
plants by increasing desiccation, especially if winds persist over long periods 
of time, but I don’t think a single night of very low wind chills will have 
much impact on dormant trees.  With very cold nights and high winds, I suppose 
there could eventually be some freeze-drying effects, but I don’t think I’ve 
ever heard much about that kind of damage on trees?
