In a Nutshell

    Brown spore cushions on the leaves and stalksDeformed leavesReduced plant growth

Hosts: %1$s

· Pea · Pigeonpea · Chickpea

Symptoms

Brown spore cushions appear on both sides of the leaves as well as on stalks. In dry weather conditions, these spore cushions spread out. Leaves become deformed and the whole plant has meagre growth. Nevertheless, the yield is little reduced.

Trigger

The fungus hibernates on field beans (also known as bell beans, broad beans or English beans), vetches and varieties of spurge. From there, it spreads to pea plants in spring. In winter, the fungus moves on to a new host.

Biological Control

The damage is mostly detectable at a late state of the disease. Treatment is not necessary in most cases, since revenue losses are low.

Chemical Control

Fungicides based on Tebuconazole can be used

Preventive Measures

    Remove all alternative hosts in the vicinity, such as Vicia species (broad bean) or Lathyrus (Vechtling)
