A single, plastic population of Mycosphaerella pinodes causes ascochyta blight on winter and spring peas (Pisum sativum) in France.
Plant diseases are caused by pathogen populations continuously subjected to evolutionary forces (genetic flow, selection, and recombination). Ascochyta blight, caused by Mycosphaerella pinodes, is one of the most damaging necrotrophic pathogens of field peas worldwide. In France, both winter and spring peas are cultivated. Although these crops overlap by about 4 months (March to June), primary ...
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 کاملStudies on the Control of Ascochyta Blight in Field Peas (Pisum sativum L.) Caused by Ascochyta pinodes in Zhejiang Province, China
Ascochyta blight, an infection caused by a complex of Ascochyta pinodes, Ascochyta pinodella, Ascochyta pisi, and/or Phoma koolunga, is a destructive disease in many field peas (Pisum sativum L.)-growing regions, and it causes significant losses in grain yield. To understand the composition of fungi associated with this disease in Zhejiang Province, China, a total of 65 single-pycnidiospore fun...
متن کاملVirulence 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...
