摘要The white pine blister rust caused by Cronartium ribicola is one of the most severe diseases of Pinus armandii Franch in Yunnan Province, China, and controlling the disease is very difficult. A mycoparasite (Trichoderma atroviride P. Karsten SS003) we isolated can effectively destroy aeciospores. Microscopic analysis showed that aeciospore warts started to fall off 3days after SS003 inoculation, and the outer wall of the aeciospores was deformed and completely broken 5days after treatment. SS003 treatment indoors and in the field was effective against C.ribicola. SS003 mycelium grew well on aeciospore piles, and the outer walls of most aeciospores were broken when examined by microscope. The average efficacy of SS003 against Armandii pine blister rust reached 71.85% after continuous treatment for 1.5years in the field. Additionally, safety tests showed that P. armandii seedlings experienced no side effects when they were inoculated with either conidial suspensions or mycelium solution of SS003. Our results suggest that T. atroviride SS003 is a promising mycoparasite for controlling Armandii pine blister rust.
