Pest management schedule

In order to be successful, an IPM program should follow a schedule of monitoring and cultural controls that is repeated each year. Read about the specific pest to determine how to monitor for the pest, and to decide what level of pest infestation can be tolerated.

Time Action
Early spring before bud break Prune trees before bloom to improve air circulation within the tree canopy. Remove and burn any branches with black knot or brown rot.
Remove and dispose of any mummy fruit still on the tree.
For plum trees with a history of plum pockets, apply a single application of fungicide.
Bud break If the tree has a history of blossom blight and twig blight caused by brown rot, apply fungicides to protect blossoms. Repeat application according to label instructions until petal fall.
Bloom Check trees during bloom to make sure bees are actively pollinating flowers.
After frosts, check to see if the center of the blossoms are green (healthy) or black (dead).
2 weeks post bloom For cherry trees with a history of significant leaf loss from cherry leaf spot, apply a fungicide spray to protect mature leaves. Repeat application according to label instructions until after harvest.
Shuck fall to small fruit Monitor for plum curculios ; manage them if any adults are present.
Mid May through June Place traps for spotted wing Drosophila in trees and check them regularly throughout the growing season.
July through harvest If spotted wing Drosophila are present, harvest ripe fruit, properly dispose of infested fruit and apply insecticides.
Mid June - harvest Place sticky card traps for cherry fruit fly in cherry trees. Use appropriate management measures if adults are found.
June-August Monitor trees for cherry leaf spot. If leaves develop spots and drop early rake and remove all leaves in the fall. If defoliation is severe, consider using protective fungicides the following year.
2-3 weeks before harvest For trees with a history of significant brown rot infection of fruit, apply fungicides to protect ripening fruit. Repeat application according to label instructions until harvest.
Harvest Pick all ripe fruit on the tree. Harvest rotten fruit separately from healthy fruit. Compost or bury infected fruit. Pick up and dispose of any fruit that falls on the ground.
Fall If cherry leaf spot infected the tree, collect and remove all fallen leaves.
Remove weeds next to tree trunk to discourage mice.
