Disease Organisms Symptoms Occurrence Hosts Control
Ascochyta
blight
Ascochyta lentis On leaves, small round whitish lesions
with brown margins. Lesions often
containing small black fruiting bodies
of the fungus. Lesions can also form on
stems causing premature death. Pod
infection can ultimately result in black
discolourations on seed
Common in all lentil growing
regions in southern Australia. All
varieties except Northfield are at
risk of seed infection by ascochyta
blight.
Damage is most likely in wet
seasons
Lentils – seed,
stubble and self
sown plants
Seed dressings.
Resistant varieties.
Foliar fungicides.
Crop rotation.
Avoid early sowing
Botrytis
grey mould
Botrytis spp. Leaves: White round lesions-spots
without black fruiting bodies as in
ascochyta blight.
Stems: Light brown sections form on
stems that are covered with fluffy grey
mould. Botrytis grey mould can cause
branches to die and cause discoloured
and shrivelled seed.
In severe cases large brown patches
can form in the crop
Most likely to occur in dense,
lodged crops when there is frequent
rain late in spring
Most legumes Seed dressings.
Low plant density.
Avoid early sowing.
Foliar fungicides.
Crop rotation.
Resistant varieties
Alfalfa
mosaic
virus
Virus Tip necrosis Prevalent in lentil production
regions
Wide host range
including most
pulses, some
horticultural plants
and weeds
Virus free seed,
management of
weeds, resistant
varieties
Cucumber
mosaic
virus
Virus Yellowing, stunting Common in all lentil growing areas Very wide host
range, including
most pulses,
pastures,
horticultural
crops and weeds
Virus free seed,
management of
weeds, resistant
varieties
Beet western
yellows virus
Virus Yellowing, stunting Present in all lentil production areas Very wide host
range. Most pulses
and brassicas and
many weed species
Managing weeds
and aphids,
resistant varieties
