Once it infects any section of a plant, it can quickly spread to other healthy parts of the plant. They tend to affect plants that are injured or damaged and are on the verge of dying. They occur on wet plant surfaces and can infect almost every common plant species. The development of Botrytis molds, or gray molds, is mainly caused by moisture. These fuzzy structures contain thousands of microscopic spores that can become very active and can spread at the slightest activity. If the humidity is extremely high in your home, you may notice web-like structures covering the leaves, possibly spreading and making the flowers appear grey when observed from afar. These spots will start to turn greyish and finally brownish, making them easily mistakable for brown mold. To know that your plants have been infected by gray mold, be on the lookout for spots on leaves, stems, buds, and petals that appear whitish and seem to be water-filled. Excessive inhalation of these spores can cause allergies and other respiratory issues. They are common outdoors but can also be found on plants that are grown indoors or in greenhouses.ДЄlthough it develops on plants, Botrytis spores can be found in indoor and outdoor air throughout the world. However, it has recently been shown that plants do not always show symptoms upon infection, and can often show delayed symptoms once the fungus has already spread to various parts of the plant. Plants produce localized lesions when attacked by Botrytis molds, which are usually visible to the naked eye. You can find the gray mold on wounded plant tissue, including fruits, flowers, leaves, shoots and storage organs. Botrytis cinerea on Riesling grapes Where to find Botrytis mold at home?Д«otrytis molds are frequently found in damp areas of homes and in gardens. Various Botrytis species have also developed resistance to many fungicides, thus being able to fight back against human intervention. cinerea has been found to exhibit many phenotypic and genotypic variations. Over time, Botrytis species have proved to be adept at changing their morphology and function, which to enables them to live in many different environments and infect such a wide range of plant hosts. Botrytis conidiophores Adaptability of BotrytisДЄdaptability refers to how an organism changes or adjusts to fit and survive in its changing environment. Other common species of Botrytis fungus are B. fragariae is a recently discovered species which affects strawberries and is also of great economic importance. cinerea is exceptional in that it affects about 1000 species of plant host, whereas other species only affect a few hosts with some being host-specific. cinerea which is subject to extensive study owing to its substantial economic impact. Known Botrytis speciesД«otrytis has about 30 species that have been scientifically identified.

Most Botrytis species are plant parasites, but some of its species are saprophytes. The gray colour originates from asexual spores (conidiospores) which can be spread by water or wind.Д«otrytis molds mostly occur in the asexual (anamorph) forms, but sexual (teleomorph) forms have also been described. It first attacks a plant in the form of a white growth which over time develops into a gray mass with a velvety appearance. The most common species of Botrytis, B.cinerea, is commonly referred to as gray mold. Considered by many to be archetypical examples of necrotrophic fungi, they are primarily known for the damage they cause to hundreds of plant species, notably grapes, raspberries and strawberries. Botrytis is a genus of anamorphic fungi belonging to the Sclerotiniaceae family.
