Treatment
There is no cure for plants that already have damping off. However, you can easily prevent the problem by providing good air circulation. A small fan or simply cracking the lid of the germination tray will suffice. The biological fungicide Mycostop may also be used as a seed treatment to prevent seed or soil-borne diseases. Other steps for preventing damping off include the following:
When starting seeds indoors, use good organic potting soil or sterilize your own potting soil in an oven.
Make sure your seed starter mix is light and fast-draining.
Plant seedlings so that the soil surface is near the top of the container to insure proper air circulation.
Sow seeds thinly to prevent over crowding which can lead to humid, moist conditions.
Seedling trays that provide water from below are preferable to overhead watering.
Never water past noon so that the soil surface and the plants are dry by evening.
Avoid overwatering tender seedlings.
