Heterobasidion Root Disease Interactive Guide
Result
HRD is not present in the stand AND the stand IS within 25 miles of a confirmed HRD stand.
Learn more in Chapter 3 of the HRD guidelines.
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 risk of impact is not considered high based on the current scientific information about the disease and observations in Wisconsin.
Things to consider
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 if HRD were to develop in the stand. It is important to note that there are no treatments to eradicate the pathogen after it infests a stand.
