[Fr., f. fumago.]
A black superficial mould on plants, caused by fungi once grouped under the name Fumago, and associated with the honey-dew produced by certain insect pests.
[1879G. B. Buckton Monogr. Brit. Aphides II. 20 Passerini remarks that Rhopalosiphum dianthi is one of the most destructive Aphides in foreign greenhouses. They there give rise to a kind of mould on the plants they infest, to which the French give the name Fumagine.] 1913D. Grant tr. Bourcart's Insecticides 393 Fumagine is the term applied to the black coating which appears on certain plants infested by plant lice or cochineals (scale insects). This coating is formed by the black mycelium of a fungus which lives solely on the saccharine liquid, the honey-dew, which the insects project on the leaves. |
