Plants - show reduced emergence, yellowing and/or browning (necrosis) of leaves beginning at tips
Reduced bulb size, bulb decay, and brown, poorly developed root systems
In storage - bulbs show spongy, sunken, yellow brown rotting lesions
In early stages - infected bulbs are softened, brown and watery when cut open
White, light pink or reddish fungal growth covering the cloves or in rot cavities
Deep cracks form in the cloves, followed by break down of the tissue, which will eventually dry down to a portion of its original size, the cloves becoming crinkled and small
Soil borne fungus and can persist for long periods in the soil
Transmission - infested soil on tools or equipment, infected debris, infected seed, or run-off water
Pathogen enters the plant through wounded tissue
Disease develops from the base of the bulb and progresses towards the tips of the cloves
Favored by higher RH and temperatures(20-30 ° C)
Avoid rotations with Allium spp.(e.g. onions and leeks) and cereals
Store bulbs at cool temperatures and low humidity with good ventilation
