Bulb rot on Tulip caused by Botrytis tulipae
Bulb decay in Tulips can be caused by Botrytis tulipae or B. cinera. When bulb decay is caused by B. tulipae,the disease is known as “fire” and the diseased flowers arising from infected bulbs are known as ‘fireheads’. These fungi are common in the environment and infect bulbs through injuries caused by insects or improper handling. Only intact, undamaged bulbs should be stored or planted. Discard any bulbs with signs of fungal infestation. Store bulbs in a dry, cool area in onion bags or loose layers of peat or hay. Bulbs can be treated with hot water to eliminate pathogens or dusted with an appropriate fungicide (thiophante methyl, iprodione, captan) before planting.
