Introduction to the Symptoms and Control Methods of Seedling Blight in Calla Lilies

What do the symptoms of seedling blight in calla lilies look like, what are the transmission routes, and how do we go about controlling this disease? Let's take a look together.

Symptoms: It causes rot of the bulb sprouts, browning of seedling leaves, and shriveling and curling. When the sprouts are not damaged, they can still grow normally; if the affected leaves dry up and wrap around the terminal bud, it causes stunting or poor stem emergence. Besides damaging the leaves, this fungus can also harm the base of the stem, causing browning symptoms at the sprouting sites and forming wounds that facilitate further damage by bacterial soft rot.

Transmission routes: This fungus can survive as mycelium on plant debris or vegetative propagules. It is introduced via infected bulbs or directly infects from the soil.

Control methods:

1. Bulb disinfection.

2. Soil fumigation.

3. Remove diseased leaves, and refer to the use of dexon or fudonin chemicals for drenching.
