I sprayed Surround on my apples for about five years, beginning right
after petal fall and then every week or two or whenever it rained
about an inch. I got good coverage using a gasoline powered Stihl
backpack sprayer. In those five years, I harvested almost no apples
and would often see curculio scars on the fruits the day after I
sprayed!
