Aspergillus is most commonly found in the soil around us, where it thrives on naturally occurring organic debris. Some species are known to colonize stored cereal grains not only causing losses but also producing mycotoxins such as trichothecenes, zearalenone, and fumonisins that are harmful to humans and animals(1, 3). P. aeruginosa infections in humans can invade nearly any tissue in the human body, provided they are already weakened.

To avoid food poisoning, food preservation is done in various ways like pasteurization, salting, boiling etc. Harmful microorganisms not only damage the human body, but also the food we eat. These problems may be worse in those who have weakened immune systems, are prone to autoimmune diseases, or are generally sensitive to environmental allergens. As the table grape season in Chile starts up, a defect to keep an eye out for is sulphur dioxide injury. Aphids can transmit dozens of viruses from a diseased plant to healthy in few seconds, especially through the winged generation. Botrytis, Cladosporium, Fusarium, Geotrichum, Monilia, Manoscus, Mortierella, Mucor, Neurospora, Oidium, Oosproa, Penicillium, Rhizopus and Thamnidium. Specifically, the omnipresent spores of botrytis. Scientific investigations have confirmed the compatibility of the fungal species used with humans. in my opinion, and sign of P.M you should take out the effected plant, quickly and carfully . Beside this, is Botrytis cinerea harmful to humans? Fungicides, also known as antimycotics, are pesticides used to eliminate or inhibit the growth of fungi. By causing flowers to die or never bloom at all, powdery mildew prevents plants from growing fruit. Botrytis forms two types of resting structures on or in infected plant tissue: 1) very dark brown or black multi-celled structures called sclerotia and 2) single-celled, thick, dark walled chlamydospores.
