gummosis |
|
The hard gummy substance on the outside of bulbs is characteristic of the condition, gummosis. Susceptibility to gummosis varies by variety and maturity, with mature bulbs being more resistant. Gummosis may result from mechanical injury or ethylene gas produced by the fungus Fusarium sp., which can colonize bulbs. |

leaf distortion |
|
Leaves showed white tissue in areas on the margins and areas of white flecking located symmetrically on the leaves. A representative from Yoder Bros. said they call this the "Lisa problem". Yoder has done extensive virus/viroid testing over time and we have never been able to associate a virus or viroid. Likewise, they have done foliar and soil analyses and not been able to associate anything consistently. Also, they have never been able to associate spray injury, etc. Yoder sees this on 'Lisa' usually in the heat of the summer. The sunken white flecks are not apparent in cooler temperatures. Usually the crop grows out of it. After several years, this flecking symptom has not been considered a major problem for the chrysanthemum crop. |
