Sirococcus shoot blight, caused by the fungus Sirococcus conigenus, is the most serious forest pest problem in red pine plantations. Red pine trees of any size can be affected and entire plantations have been killed by this disease in Nova Scotia. This report describes trials conducted to test and demonstrate whether sirococcus shoot blight can be controlled by pruning in red pine plantations in Nova Scotia. Four plantations having different degree of blight infection were used as test sites. One plantation with a high infection rate was used as control, and the others were subjected to treatments consisting of pruning, removing, and burning all infected shoots and branches. Plots were then assessed annually during fall to early spring from 1989 to 1992. Recommendations for red pine management are made based on the results.
