Wild Blueberry Newsletter July 2022
Dear Growers, Processors, and Stakeholders,
We are starting to see and hear accounts of drought-related stress in wild blueberries. So far the locations with drought stress are on a ledge or in fields that are burned very frequently. These locations have less organic matter (water holding sponge) than is ideal. If you see this stress in your fields contact your county NRCS office and talk with them about mulching and irrigation cost share programs. The wild blueberry growing areas of Lincoln, Knox, Waldo, and Hancock counties are in a “Moderate Drought” while Washington county remains “Abnormally Dry” according to the U.S. Drought Monitor. If you have irrigation, it should be used to apply approximately 1 inch of water per week to both prune and crop fields.
It is time to begin monitoring for Spotted-Wing Drosophila.
Weather is an important driver of SWD activity. The last few weeks have brought excellent weather conditions for Spotted-Wing Drosophila populations here in Maine. High humidity and warm conditions will likely lead to earlier captures of SWD. This year, our traps at wild blueberry monitoring sites Downeast and in Mid-coast have already trapped SWD males and females in low numbers. Similar to the last couple of years populations will likely build as the crop ripens and harvesting starts.
Monitoring for SWD on your farm.
With great variation between sites and regions that grow wild blueberry here in Maine, monitoring for this pest on your own farm is the only way to be sure, if and when management might be necessary. Monitoring for both the adults in the field and infestation in the fruit is recommended when ripe fruit is present. For guides on how to monitor for SWD on your farm, along with information about cultural control, action thresholds, and chemical control please consult the 210-Spotted Wing Drosophila: Pest Biology and IPM Recommendations for Wild Blueberries on the Cooperative Extension: Maine Wild Blueberries website. An excellent How-To Trap SWD Video can be found on the Wild Blueberry Videos page of our UMaine Extension website.
