Aquatic Plant Control Research Program. Assessment of Fungal Pathogens asBiocontrol Agents of Myriophyllum Spicatum

摘要

In the 2 years of this project (1994-95), nearly 200 sites in the United Kingdomand mainland Europe were surveyed for fungal pathogens that could be used as biocontrol agents against Myriophyllum spicatum. Over 400 potential pathogens in 38 genera were obtained in pure culture. Isolates have been screened for pathogenicity on sections of plants; of these, 13 have been shown to possess some control capabilities. These include two isolates of Gliocladium roseum, two indeterminate Hyphomycetes (producing only chlamydospores), Acremonium sp., Cylindrocarpon destructans, Embellisia nr. telluster, Fusarium solani, Geotrichum candidum, Coniothyrium fuckelii, Cryptosporiopsis sp., Glomerella cingulata, and an indeterminate Coelomycete.
