Organic farming is highly dependent on legumes to build soil fertility. However, declining trend
is present inlegume, especially spring pea production in Germany. The reasons are beside low
yield, foot and root diseases. Therefore, winter pea should be considered as possible alternative to
spring peas. Climate change scenarios predict an increase in winter precipitation and temperatures
which are expected to favor winter over spring pea. Winter peas, especially in mix cropping with
cereal, provides good weed suppression, prevents soil erosion and better uses winter moisture.In
addition, winter peais a good pre-cropand can be used in two-crop systems (winter pea followed
by maize). The hope is also, that winter peas are less susceptible to root rot pathogens. However,
little data are available. Therefore, study was carried out to evaluate the susceptibility of the
winter pea variety EFB33to different isolates of Fusarium avenaceum, F. solani f. sppisi, M. pinodes
and P. medicaginis under controlled conditions compared to the spring variety Santana. Three
weeks after sowing and inoculation disease symptoms were assessed and plant growth parameters
measured. All of the tested pathogens resulted in disease. Reductions in fresh weight per unit of
external tissue damage on Santana were significantly different among pathogens with 12.5% for
F. avenaceum, 8.8% for P. medicaginis, 8.4% for M. pinodes and 3.8% for F. solani, respectively.
Overall, EFB33 was less susceptible and the highest reduction of fresh weight caused F.
avenaceum, 15.8%. No significant difference was observed among other pathogens.
