Regular seasonal spraying is very important for fruit production in Western Oregon. Timed sprays help to control fungal diseases, insects and some bacterial diseases.
When spraying in Fall, Winter, and Early Spring, sprays should evenly coat all branches and the trunk.
Late Spring and Summer sprays should be applied according to label instructions. Bloom stages are used to time spray applications:
- Pre-Pink – buds are swelling but not showing any color
- Pink – first show of color, but flowers are not open
- Petal Fall – last flowers have fallen
Please note that these stages vary from year-to-year based on weather, so it is important to watch your trees during critical times.
