However, white grubs (reaching 40–45 mm long when full grown) live in the soil and feed on plant roots, especially those of grasses and cereals, and are occasional pests in pastures, nurseries, gardens, and golf courses. An obvious indication of infestation is the presence of birds, such as crows, peeling back the grass to get to the grubs.
Symptoms are variable and range from stunted growth to curled young leaves. The soft tissue symptoms are more evident in spring and new leaves will reflex towards their own petioles. The affected leaves are brittle and easily fall from the plant. Fully formed leaves will appear to wilt as if the plant were water stressed.

Water promotes disease development as the pathogens only undergo germination and infection after more than nine hours of leaf wetness. [7] A. brassicae and A. brassicicola cause very similar symptoms, with symptoms normally occurring on older leaves, as they are closer to the soil and more likely to be affected by rain splash, which spreads the ...
