In Vitro Evaluation of the Resistance of Seven Isolates of Colletotrichum acutatum to Thiram and Copper

摘要

Seven Isolates of Colletotrichum acutatum have been collected from strawberries attacked with anthracnose in the Loukous territory, Morocco. The study of the effect in vitro of 3 fungicides with Thiram as active substance and another one with copper on seven isolates of C. acutatum was studied. Thiram has a potent effectiveness on germination and is moderately effective on mycelial growth and sporulation. Copper has shown effectiveness on germination as variable activity in other strain’s life stage.
