During June and July, crop scouting for the ascochyta/mycosphaerella complex in field pea is critical for assessing risk and gauging the need for and timing of an in-crop fungicide application. However, late season crop scouting is also important as it can be used to assess the prevalence, severity and impact of these disease issues. Where unsprayed check strips or areas have been left in the field, late season assessments can be used to assess the impact and benefit of spraying in relation to leaf disease management and crop productivity.
Assessment protocols and scouting information are now available at the links below for the ascochyta/mycosphaerella complex in field pea.
The main leaf diseases in field peas:
- Ascochyta blight caused by
the fungus Mycosphaerella pinodes;
- Ascochyta leaf and pod
spot caused by the fungus Ascochyta
pisi
