Cause Various Fungi, Penicillium spp. In Washington, penicillium hirsutum has been discovered on iris. In Denmark, P. tulipae and P. hirsutum both exhibited more severe symptoms than other species. These fungi typically target weak or damaged bulbs caused by various reasons, particularly damaged bulbs kept in damp environments. Additionally, reports of these fungi on other bulbous plants, such as crocus, gladioli, iris, and onions, have been made.
Symptoms Bulb storage causes brown stains to appear. On the bulb, the basal root plate, or in the spaces between the scales, a blue moldy growth may appear. Leaf initials and surrounding tissues may become internally discolored. The entire bulb could be impacted, becoming dry and hard. The foliage on sprouted blubs may be reddish-stunted.
- Dig bulbs at the appropriate time and handle them gently to prevent harm, such as bruises or sunburn.
- Store with gentle air circulation and moderate humidity.
- Dispose of damaged and unhealthy bulbs.
- Before replanting tulips on the same ground, give the area long rotations. Take out stray plants from earlier bulb crops.
