Golovinomyces Cichoracearum

In 2005, the authors encountered a previously unreported powdery mildew disease of Coreopsis verticillata L. (whorled tickseed) ‘Zagreb’ and C. auriculata L. (lobed tickseed) ‘Nana’ in central Washington and determined the causal agent to be Golovinomyces cichoracearum (DC.) VP Gelyuta. This report documents the occurrence of G. cichoracearum on Coreopsis species in the Pacific Northwest, and describes diagnostic features of the disease and causal agent.

Noxious Weed

Common teasel (Dipsacus sylvestris) is a European species introduced into North America, and is now widely established and regarded as a noxious weed. In October 2005, a powdery mildew was observed on D. sylvestris in two locations in Pullman, Whitman Co., WA. Examination of diseased material confirmed that the causal agent was S. dipsacearum. This report provides the first documentation of S. dipsacearum on D. sylvestris in North America. Accepted for publication 20 April 2006. Published 7 June 2006.

Golovinomyces Orontii

Periwinkle is a trailing, spreading evergreen plant used in landscapes as a groundcover. Beginning in 2005, a powdery mildew was observed on periwinkle in coastal (Monterey Co.) California. As reported herein, the causal agent was determined to be Golovinomyces orontii (Castagne) V.P. Heluta. This appears to be the first record of a powdery mildew species on Vinca spp. in North America.

Leveillula Taurica

The effectiveness of benomyl, chlorothalonil, copper hydroxide, dinocap, sulfur and triadimefon for the control of the fungus Leveillula taurica, causal agent of the powdery mildew of peppers (Capsicum annuum), was evaluated under field conditions. Results from two experiments indicate that weekly applications of benomyl and triadimefon reduced disease incidence and increased pepper yield. In the first experiment, plots treated with triadimefon (0.35 L/ha) and benomyl (0.55 kg/ha) produced 20.2 and 17.2 kg fruit/plot, respectively, whereas the nontreated plots yielded 13,9 kg/plot. A similar trend but with higher yields was obtained in the second experiment. Treatments with triadimefon (0.70 L/ha) and benomyl (0.55 kg/ha) produced 41.0 and 41.3 kg of fruit/plot, respectively, as compared with the control treatments which yielded 29.0 kg/plot.
