Damping-off is the term gardeners use to describe the wilting and death of seedlings just before or just after they emerge from the soil. Damping-off of seedlings and early foliar blight are generally attributed to AG 4. Growers need further chemistry for alternation to keep disease under control and to reduce the risk of resistance developing.

First, it is the causal organism of root and stem diseases of potatoes, beets and other root crops; second, it is one of the main causes of damping-off among seedlings of many species of plants; and third, it causes a foliage blight of sugar beets (12). Biological control of damping-off disease of sugarbeet (caused by Pythium spp.) The best known type of Damping Off first manifests itself as a fuzzy whitish mold on the surface of the soil and then goes on to girdle the succulent stems of newly germinated plants.

As with most minor crops there is a gap in the available fungicides for treatment of major diseases. Do not use garden compost or reuse potting soil for starting seeds. Do not plant in cold, moist soil. Seedlings that suddenly collapse or fall over or bare spots in containers or in the garden where seeds were sown but never appeared are signs of damping-off. A 3-year study was conducted to evaluate the effectiveness of two disease-suppressive Streptomyces spp. The leaves are oval in shape, arranged alternately on the stem and grow 20–40 cm (7.9–15.7 in) in length.

Damping off is a fungus that lives in the soil, particularly where humidity is high. All isolates colonized roots well, so differences in activity were unlikely to be due to differential colonization.

C. Source: Phytopathology 2012 v.102 no.4 pp. Root and crown rot on mature roots is primarily caused by AG 2-2 IIIB, but intraspecific group IV can also cause some limited damage. If spring rains are heavy, cover containers to reduce risk of waterlogged soil and damping off. For example, the AG that causes disease on wheat is the same one that induces damping-off in sugar beet seedlings (AG-4), but is different that the one that causes root and crown rot in beets (AG2-2).
