You may have received a box of fruits that contained citrus fruits that looked like the ones in the video. A black layer colors the beautiful color of the citrus fruits. You're probably wondering what this is all about. Is it dirt? Are they little animals?
Neither. It is negrilla, also called fumagina. It is a fungus that develops on the sugary secretions, called honeydew, of insects such as aphids or whiteflies. The insects feed on the proteins they find in the plants and excrete the substances they cannot utilize: the sugary secretion. This secretion then provides the ideal source of nourishment for Negrilla.
The black powder is therefore a fungus that covers leaves, other parts of the plant and fruits. Ideally, the rain simply washes away the negrilla fungus.
It is important to understand that although the fungus does not look very nice, it does not cause any danger. It can be easily removed with a damp cloth or a dry brush, because it is only an aesthetic blemish. You can enjoy the fruit and the peel without hesitation.🍋🍊
