Bonide Sucker Punch - Manual (Page 4)

Apple and pear trees, healthy, vigorous and free from stress may be treated
after planting when the trees show established growth. Remove sprouts
and follow the application procedures described below. Do not apply to non
established or stressed trees as injury and stand loss will result.
NEW PLANTINGS
Prune existing sprouts and treat during the dormant season. Thoroughly
cover area where existing sprouts were removed but restrict treatment to
the cut surfaces and 2 to 3 inches of the surrounding area. Avoid fine spray
particles from drifting or splashing on surrounding fruiting wood or buds.
Do not treat scaffold limbs after bud activity starts in the Spring. There has
been some fruit size reduction on Golden Delicious and Anjou pears from
excessive treatments to scaffold limbs on older, weaker trees. To minimize
the chance of injury, limit treated areas to 10 percent of the total bark area
of the tree. Do not treat weak trees and do not repeat applications on the
same tree for at least one year.
ESTABLISHED PLANTINGS - SCAFFOLD LIMBS
Prune existing sprouts and apply this product during the dormant season
prior to green tip stage or during the Summer pruning season when the
new shoots are 6 to 12 inches in height. The later applications have been
the most effective. On bearing trees do not treat suckers during bud swell,
bloom or fruit set. This period is from the start of growth to 4 weeks after
petal fall. Application during this time can result in excessive thinning. Avoid
spray drift of fine spray particles.
