(1995) that has the following scores: 0 = no symptoms; 1 = hypocotyl with small lesions; 2 = hypocotyl with large lesions, but without constriction; 3 = hypocotyl totally constricted and showing damping-off
; 4 = non-germinated seeds and / or seedlings not emerged.
They reported that the incidence of damping-off
was found maximum in the pathogen inoculated control (54.67%) and lowest in the plants treated with the consortium of Trichoderma isolates BHU51+BHU105 (22.00%) rather than the individual application of Trichoderma isolate BHU51 and BHU105 on to seeds.
According to the experimental data in the present study, the methanol extracts of Coptis Rhizome powder and the indicator compound berberine chloride have the potential to be explored as new plant derived pesticides to control Rhizoctonia damping-off
in vegetable seedlings.
If space is left between the soil surface and the rim of the container, damping-off
fungus is likely to develop in the resulting dead-air space.
Suppression of damping-off
disease in host plants by the rhizoplane bacterium Lysobacter sp.
-MUCH more daylight and (hopefully) warm sunshine now that spring has sprung means much more watering in the greenhouse and under outside cloches.Open doors and vents whenever possible so air can circulate and reduce the risk of damping-off
disease killing developing plants.
Solution: These plants have the dreaded damping-off
disease commonly occurs when greenhouse-grown tall fescue plants are established to determine viable endophyte content of seed (Hill and Bouton, personal observation).
Keep seedlings moist enough to avoid wilting, but be careful not to overwater, which promotes damping-off
. Mulch with dark, heat absorbing mulch or black plastic for heat after soil is well warmed.
