Checkout the latest Fruit Pest Advisory!
The latest Fruit Pest Advisory is now available. Although spring activity is still about three weeks ahead of “average,” the cooler temperatures starting today will slow plant (and pest) growth down. Unfortunately, the early spring meant early blooms that are susceptible to frost damage.
Assessing frost damage:
• Temperatures of 26°F or lower occurred in some fruit-growing areas early this morning. If this temperature is sustained, fruit losses can occur.
• A picture is provided in the advisory link below, but to check for damage, wait 3 to 7 days from now, and slice flowers or fruitlets in half to see if the tissue inside is brown (dead) or green (live).
On apple and pear:
• Codling moth: For a few locations, a treatment date is provided, but it is a month away. The next advisory will provide more accurate dates.
• Powdery mildew: Apply a fungicide after bloom.
On peach/nectarine and apricot:
• Powdery mildew and Coryneum blight: Apply a fungicide at shuck-split stage (when the brown papery husk splits from the fruitlets), which will be earlier on apricot than peach
• Green peach aphids are becoming noticeable but could be ignored.
