Hi All:
Don't forget that when Alternate Row Middle (ARM) spraying was almost universal
in PA the half sprays were applied every 7 days rather than applying a full or
complete spray every 14 days. Later in the season the intervals were extended
considerably. One major advantage of ARM sprays is that it takes one-half as
long to get some coverage as it would take to make a complete spray. That can
be advantages when there may be an approaching weather event such as a front
with lots of rain and wind.
So with chemicals that have a pretty short half life it was felt that a
complete coverage on one side of the tree and partial coverage on the back side
knowing that you would do the reverse in 7 days.
I have heard that today there are some concerns about resistance management
with ARM Sprays. I am not a pest control person so I am just giving a history
lesson on ARM sprays. Of course many pests and pesticides have changed now so
ARM sprays may not be advantages for current orchardists.
Be well, George Greene
