The Occurrence of Fungal Diseases in Maize in Organic Farming Versus an Integrated Management System

Organic farming is becoming increasingly popular because it leads to healthier products. Due limitations on the use of chemical protection, however, plants may be more susceptible pathogen attacks. Therefore, aim study was determine occurrence fungal diseases in maize grown organic versus integrated systems. The field experiment conducted during years 2017–2019 Puławy, Poland. Three varieties, Ambrosini, Smolitop and Ricardinio, were cultivated two fields with a different crop production system. incidence diseases, such as northern corn leaf blight, eyespot, common rust, smut Fusarium ear rot, assessed. Fungal isolates collected from leaves cobs disease symptoms identified microscopically molecularly. In both cultivation systems, blight eyespot most common, while rust fusariosis seen often cultivation. Alternaria alternata, oxysporum, poae, graminearum sporotrichioides species frequently detected Additionally, verticillioides Weather conditions, especially heavy rainfall high air humidity, greatly influenced diseases.
