Book Description
Cercospora leaf spot, caused by Cercospora beticola Sacc., is the most detrimental disease of sugar beet (Beta vulgaris L.) in the Great Lakes Region. Field trials determined efficacy of BEETcastTM 50/35, BEETcastTM 55/50, and calendar spray schedules using 115 or 235 L ha 1 carrier volume with disease severity value (DSV) accumulation beginning at 1 May or crop emergence. Disease progress was minimized by spray schedules with conservative application intervals compared to longer application intervals. Area under the disease progress curve was reduced by a carrier volume of 235 L ha 1 compared to 115 L ha 1 at one of five sites, and DSV start date at emergence compared to 1 May at one of two sites. Aerial C. beticola conidia concentration was assessed in 6 h intervals and peaked in September with daily mean maxima from noon to 6 pm. Daily mean air temperature was related to daily mean conidia concentration when all data were considered and when concentration exceeded 30 spores m 3.

Innovative Methods for Detecting and Managing Cercospora Beticola

Category : Electronic dissertations

Pages : 233
Book Description
In many parts of the world, including the Great Lakes region of the United States, Cercospora leaf spot (CLS), caused by the fungal pathogen Cercospora beticola, is a major foliar disease of sugar beet (Beta vulgaris subsp. vulgaris). CLS management has become challenging in recent years due, in part, to an increase in fungicide resistance. If CLS is to be successfully managed in the future, more information about its epidemiology and alternative management strategies will be necessary. Thus, my first study employed sentinel beets to detect C. beticola spores in the field during the first half of the growing season. In both years of the study, spores were detected earlier than any previous reports. The spore levels detected fluctuated during both seasons and were correlated with factors such as rainfall and relative humidity. This information could be used to improve the timing of fungicide applications. The second study examined the potential of bicarbonate salts to be used as fungicides for C. beticola management. Ammonium, potassium, and sodium bicarbonate were tested in vitro. Each inhibited the growth of C. beticola, with ammonium bicarbonate causing complete growth inhibition at 1% (w/v). Sodium bicarbonate at 2% (w/v) significantly reduced CLS in the greenhouse compared to a control, so it might be useful in the field. The third study tested the effects of heat treatment in the form of a propane torch on C. beticola in vivo, with the goal of using such a technique to reduce inoculum levels of the fungus. Heat treatment of infected leaves completely inhibited sporulation and decreased fungal viability by over 80%. The new insights and methods developed from this research have the potential to aid in future CLS management.
