Peter,

Am curious if you use a degree day model for knowing when the PM pressure is greatest.

Also, do you have good mineral balance in the soil and in the vine?

Having good levels of soil/vine calcium, boron, zinc and phosphate (in addition to others) has been a very, very important part of keeping PM under management with my clients/vines.
