Hi! Even if the smell was detectable ahead of visible symptoms, it would only 
happen after infection occurred. At that point, no spraying is possible. So I 
don’t see how smell would be useful (?) The only management option after 
infection is pruning out, which can’t be done by smell ;-)

The whole point of predicting infection (via computers or otherwise) is to help 
make appropriate spraying decisions, ahead of infection.
