摘　　要：在内蒙古锡林郭勒草原的大针茅上发现有由茎黑粉菌引起的黑粉病，根据以往在近缘属植物芨芨草上的调查结果，分析推断当地在针茅属植物上也有发生由针茅柄锈菌引起的锈病的可能性。对两种病害的病原菌，被用做控制大针茅和贝加尔针茅种子（颖果）危害放牧绵羊的生防作用物进行了讨论。The smut caused by Ustilago hypodytes (Schl.) Tr. On Stipa grandis P. Smirn. in Xilinguole grassland of Inner Mongolia was found in 1997. According to the survey in the past, there was a rust caused by Puccinia stipae Arth. on Achnatherum splendens (Trin.) Nevski, in the same locality. Because the Stipa and Achnatherum are close relative genera, and in the other region, the Puccinia stipae occurence yet on the Stipa breviflora Griseb. So, the same rust occurence on Stipa grandis and S. baicalensis Roshev. is possible. The possibility of the two pathogens as a biocontrol agents for control the damage of two spear grasses on sheeps was discussed.
