|
Anthracnose |
Brown sunken spots on pods. |
Destroy affect plants and spray remaining plants |
Rotate crops |
|
Bean Seed Fly |
A soil living grub which attack seeds which then fail
to germinate or produce distorted seedlings. Mainly affects early
crops. |
Destroy damaged seedlings |
Ensure the seed bed is properly prepared and dust the
drills with Chlorophos |
|
Black Bean Aphid |
Stunted growth, damaged flowers and distorted pods. |
Spray at the first sign of attack and repeat if
necessary |
Pinch out the tops of broad beans once four trusses
of pods have formed |
|
Birds |
Seeds and seedlings eaten and damage to pods and
flowers |
None |
Place netting over crops |
|
Botrytis (Grey Mould) |
Grey velvety mould on pods. |
Burn affected pods and spray remaining crop. |
Spray at flowering time if this is a known problem |
|
Chocolate Spot |
Small brown spots on leaves and dark streaks along
stems. |
Lift and destroy diseased plants and spray remaining
plants |
Apply fertiliser prior to sowing and don't sow too
close together |
|
Downy Mildew |
Yellow blotches on leaves with brown mould
underneath. Pods are spotted and distorted. |
Spray at the first sign of disease and repeat every
fortnight if necessary. |
Burn affected plants after picking. Rotate crops |
|
Foot and Root Rot |
Leaves turn yellow and shrivel. Roots and the base of
stems turn black and rot. |
Burn affected plants and water the soil with Cheshunt
Compound to avoid spreading the disease |
Rotate crops |
|
Flowers (none) |
Flowers not produced. |
Can be caused by disease but most likely is caused by
too much nitrogen in the soil |
Always use a fertiliser with phosphates and potash |
|
Fusarium Wilt |
Stunted growth. Yellowing or rolled leaves. Little
crop. |
Burn affected plants. |
Grow wilt resistant varieties |
|
Grey Mould (Botrytis) |
Grey velvety mould on pods. |
Burn affected pods and spray remaining crop. |
Spray at flowering time if this is a known problem |
|
Halo Blight |
Small brown spots surrounded by a yellow "halo" on
the leaves. Stunted plants. |
Lift and destroy diseased plants |
Never soak seed and rotate crops |
|
Leaf and Pod Spot |
Brown sunken spots on pods. Discoloured peas. |
Destroy affect plants and spray remaining plants |
Rotate crops |
|
Marsh Spot |
Brown-lined cavity in the centre of peas caused by
shortage of manganese. |
None |
Add compost prior to sowing and apply a sequestered
compound |
|
Mice |
Will eat seeds and seedlings. |
None |
Dip seed in paraffin or alum, place spiny branches
along the rows or use a normal mouse trap. |
|
Pea Aphid |
Stunted growth and damaged flowers. |
Spray at the first sign of attack and repeat if
necessary |
None |

Hoe around plants during April and May to prevent
further attack |
|
Pea Thrips |
Silvery patches on leaves and pods. Pods distorted. |
Spray at the first sign of attack |
Remove infected plants and dig over the soil before
replanting |
|
Pea Moth |
Pea moth maggots burrow through pods into seeds. |
None |
Spray just as the flowers appear |
|
Pods (none) |
No pods develop |
The loss of flowers without producing pods is often
caused by birds or bees but can also be caused by roots drying out |
Keep roots moist and mulch |
|
Powdery Mildew |
White powdery patches on both sides of leaves. Pods
are covered in white patches. |
Spray at the first sign of disease and repeat every
fortnight if necessary |
Burn affected plants after picking |
|

Small round holes appear which house the seed beetle
grub. Seeds don't germinate or produce bad seedlings. |
None |
