How does botrytis spread?

How Does Botrytis Spread? When any part of the plant is infected, botrytis spores will spread from the infected area to noninfected areas. Additionally, spores may be spread from plant-to-plant through moisture and air currents of the wind.

How does Botrytis cinerea reproduce?

Botrytis cinerea is the causal agent of gray mold diseases in a range of dicotyledonous plant species. The fungus can reproduce asexually by forming macroconidia for dispersal and sclerotia for survival; the latter also participate in sexual reproduction by bearing the apothecia after fertilization by microconidia.

How does botrytis start?

The spores start to germinate when they land on the surface of the host plant. This is also dependent on such factors as temperature, moisture and sunlight among others.
