We really think that the supplier sent us bad plants, we thought they looked bad at the time. I have a plant that shows virus symptoms in some shoots but the other shoots look normal. The recommendation was to destroy the plant. It is an unusual plant, and I want to keep growing it. Tell me how to recognize INSV on impatiens plugs - I've seen spots on impatiens for years that turned out to be no problem after a few weeks.
Symptoms vary in different temperatures, varieties and ages of plants.
After some virus problems last spring, we cleared the houses and left them empty for the summer. This fall we grew Poinsettias and they were beautiful. Weeds serve as hosts for INSV too. Poinsettias do not and therefore that crop did not show any problems. However, the annuals were probably infected by thrips that had fed on infected weeds and then moved over to the young annuals.
