Recommendation
Treatment of pine and spruce stumps is considered unnecessary because pine and spruce make up less than 50% of the stand. On species other than pine and spruce, the impact of the disease is not high and rarely causes mortality based on the current scientific information about the disease and observations in Wisconsin.
If you choose to harvest during April 1–November 30 without stump treatment, consider the potential impact to the stand and subsequently to adjacent stands. It is important to note that there are no treatments to eradicate the pathogen after it infests a stand.
