Hi Matt,
I currently own a Mankar P-50 walk behind sprayer. It was purchased
for a small Christmas tree plantation. A few of the larger Christmas
tree growers here in MN use them with good results. However, some
conifers when the new growth has hardened are tolerant to glyphosate
so I never noticed drift being an issue. I've never used it in the
orchard for fear of glyphosate damage. We had a couple rows of
Honeycrisp that had smaller, stunted leaves due to glyphosate damage
with a normal handgun sprayer. I refuse to use it in the orchard
ever again.
The Mankar walk behind sprayer does get quite tiring to push it over
large acreages especially in the summer while it is hot and the tall
weeds cause resistance on the spray hood. Also, I always wear a pair
of Tyvek coveralls and chem boots as walking behind it all day does
cause chemical to build up on clothing even though only a small
amount is emitted. It does not have a problem killing weeds several
feet tall.
Cheers,
Nick Lucking
