The time to protect apple trees from insects is near
Researchers say a third spray can improve codling moth control, and apple maggot treatments should begin as adults emerge in late June.
- Upper Midwest growers must begin controlling Codling moths soon, right after trees finish blooming, with research universities recommending Insecticides immediately after flower petals fall and again 7 to 10 days later.
- Codling larvae tunnel into Apple fruit heading for the core, leaving brown tunnels filled with sawdust-like material when small gray-brown moths lay eggs that hatch into larvae.
- Jim Walla, a retired North Dakota State University plant pathologist, relies on online prediction models for timing. Walla recently said, "If I didn't have the online models and data to use, I would plan to start spraying July 7, based on the models I."
- Adult Apple maggot flies typically emerge from late June into July, with eggs hatching into larvae nine days after adults emerge, creating winding brown trails throughout Apple flesh.
- Because Apple flowers are gone when spraying begins, bees and pollinators have essentially left the trees, reducing risks. Regardless of product choice, growers should apply Insecticides so leaves, branches, and developing fruit are completely covered.

The time to protect apple trees from insects is near
Gardening in the North has distinct advantages that we often take for granted. Milder climates might sound tempting, but regions with warm winters struggle to grow the crisp, crunchy, flavorful apples that are well-adapted our Upper Midwest backyards. Apple trees are relatively easy to grow with a little labor invested in pruning, protecting the trunks before winter and preventing insect damage to the fruits. Time spent in those three tasks yiel…
