What to Do About Rot During the Bowl Lotus Growing Period

Symptoms of Bowl Lotus Rot

Bowl lotus rot is what we commonly call rot disease. The disease affects the whole plant and gradually spreads to the stem, leaf stalks, leaves and other parts. In the early stage, the symptoms are mild and difficult to notice with the naked eye. As the disease worsens, one side of the stem turns brown, the leaves become lighter in color, and the leaves dry up until they die.

Conditions for the Onset of Bowl Lotus Rot

Bowl lotus rot does not develop all at once; it is caused by fungi that lie dormant for a long time and overwinter in the soil. The fungi lie dormant in the seed lotus roots and diseased soil, and when temperatures rise again in spring, they attack the plant.

There are differences in susceptibility among varieties. Those with deeper root systems are less affected, but continuous overcast and rainy weather with insufficient sunlight will worsen the disease.

Poor soil drainage or high acidity, dirty water quality, or water temperatures above 38°C can all easily trigger this disease.

Methods for Preventing and Controlling Bowl Lotus Rot

Select disease-resistant varieties according to local conditions, and be sure to choose pure, true-to-type seeds.

Turn the soil in time to increase soil permeability, and sprinkle some lime appropriately.

Treat the seed lotus roots before planting by spraying them with a carbendazim or thiophanate-methyl solution, then wrap them in plastic film and seal for 24 hours. Take them out, let them dry, and then transplant.

Fertilize in a timely and moderate manner, using a mix of organic fertilizer and chemical fertilizer. At different stages of lotus root growth, control the water level well, keep the depth appropriate, and maintain a moderate water temperature.
