thank you Dave for the time and effort you put into this post -
short of input from specmeters, I'll slightly exaggerate and say that the
Cornell model will predict scab infection after a short heavy dew, while the WA
model requires rainforest conditions for a couple of days before it indicates
Just remembered the fireblight trigger is reset by entering last
spray date in disease model options, not the model start date, which
IS the best way to reset the scab model.

David,
I've been using Specware for about 12 years with great success in
targeting sprays for scab and especially fireblight. I don't recall
ever seeing the Mills and Wash. models in disagreement, but I admit I
usually just go with the Mills model. The Cornell model has always
signaled infect
Hi! I agree with both Dave and Daniel, but let me add a grain of salt:
All infection events are not equal.
Plain infection models tell you nothing about ascospore availability &
discharge. Conditions may be right for spores to infect... but infection only
occurs IF spores are both mature and ej
Dave's right, the Mills model is Al Jones from about 1980. The WA model is
actually the original Bill Mills model from the 40's, and the Cornell model is
Gadoury, Stensvand and Seem's 1994 revision. Nice overview, Dave. I haven't
checked, but there may be differences between the Cornell model an
Hello, David --
I really don't know how the Spectrum instruments are
programmed, and I don't know what they are using for the Washington
scab model. Thus, this response may be of limited usefulness.
I suspect that that the differences between the Cornell and
the Mills (MI) models relate to
Is anyone else on this list using Spectrum instruments to monitor weather and
model disease? - I've had a 'Watchdog' for several years now, and yesterday had
an anomaly, with complete disagreement and inconsistencies between the three
scab models -
The software uses models from Cornell, Washin
