Good stuff Steve

I used a product last year, we sell in Canada called pHortress, which contains Potasium Phosphite. We did a trial in the patch last year with one plant only getting the pHortress and no other fungicide. The plant was free of PM for the entire season!

The rest of our plants recieved the regular fungicide treatments + phortress. There was no significant differnace in disease levels.

Interesting stuff Steve, I remember learning about phosphite a couple years back when I took a mauget tree injection class. They had seem some pretty impressive results on apples and crabapples. (I think it was on scab control) The trees also seemed to get a boost from the extra phosphorous.

Our tree & Nursery customers get outstanding Rust & Apple Scab control by applying Agrifos to the trunk with Pentrabark. No need to drill holes or waste time with foliar sprays. A 3 gallon hand sprayer is easier to lug around than a Beam sprayer too.
