The most important spray of the season for control of anthracnose on brambles is the delayed dormant spray of lime sulfur, Sulforix or copper hydroxide. If you have a problem with anthracnose, this is one spray that you can’t afford to miss. One of these materials should be applied when new leaves are exposed 1/4 to 3/4 inches; if you are late in your application and don’t spray until a few leaves have unfolded, cut the rate to reduce the risk of leaf burn.
