When the spores are mature, a crack in the needle opens along this line. Photo: Jan Byrne, MSU. Spores are produced beneath the elongated, slightly raised, black line along the infected needles.

Protectant fungicides effective against other needlecast diseases such as chlorothalonil or mancozeb may provide control. Shear healthy trees first and disinfect tools often.Ĭurrently, no information is available on the effectiveness of fungicides for control of this disease.Promote good air movement by providing adequate spacing or controlling weeds. ![]() Avoid planting spruce where Lirula needle blight occurs.Inspect nursery stock for signs of infection.MSU Extension recommends following these general plant health guidelines: Not much is known about controlling Lirula. Spores are released from these structures on third year needles. On second year needles, you will find a raised black line, which is a spore producing structure on the midrib on the underside of the needle. The current year’s needles appear to be the most susceptible. In late spring through midsummer, infected needles release spores that spread by splashing and dripping rain to new needles. The fungus overwinters in infected needles on the tree. Lirula macrospora takes several years to complete its lifecycle. Unlike other needlecasts we find on spruce, the brown needles killed by Lirula can remain attached for several years. White spruce, including Black hills spruce, is a more susceptible species. ![]() Hosts include Colorado blue spruce ( Picea pungens), and white spruce ( Picea glauca). Lirula needle blight is caused by the fungus Lirula macrospora. Recent samples of browning interior needles on Black hills spruce sent to Michigan State University Diagnostic Services found Lirula needle blight. ![]()
