Virulence and Genetic Variability Among Isolates of Mycosphaerella pinodes
Mycosphaerella blight, caused by Mycosphaerella pinodes (Berk. & Bloxam) Vestergr., is the most important foliar disease of field pea (Pisum sativum L.) worldwide (2,7,16,17,23,30,31). In Canada, average dry seed yield losses caused by this disease have been estimated at 10%, and losses of over 50% have been reported in field trials (28,34). Management for Mycosphaerella blight is limited to fu...
متن کاملDaily and seasonal spore dispersal by Mycosphaerella pinodes and development of mycosphaerella blight of field pea
Daily and seasonal spore dispersal of Mycosphaerella pinodes (Berk & Bloxam) Vestergren and the relationship of spore dispersal to distance and disease severity were investigated in a pea field in western Canada during two consecutive years. Most ascospores were released in response to rain events, during the first 23–27 d after the inoculum source area was infested with naturally diseased pea ...
متن کاملEpidemiology / Épidémiologie Temporal and spatial dynamics of mycosphaerella blight [Mycosphaerella pinodes] in field pea
The temporal and spatial patterns of epidemics of mycosphaerella blight, [Mycosphaerella pinodes] in field pea in western Canada were characterized during 2000 and 2001, using mathematical models and geostatistical analysis. The logistic model well described the disease progress over distances and in various directions from the inoculum source. The temporal disease progress rates measured by th...
متن کاملSuppression of hop looper (Lepidoptera: Noctuidae) by the fungicide pyraclostrobin.
The hop looper, Hypena humuli Harris, is a reemergent pest of hop that often requires treatment to mitigate crop damage. In 4 yr of field trials, plots treated with fungicides were observed to sustain less hop looper defoliation compared with nontreated plots. Further investigation revealed that abundance of hop looper and associated defoliation were reduced when the fungicide pyraclostrobin wa...
