Copper(II) compounds as effective agents against Colletotrichum acutatum causing strawberry anthracnose
2020
Abstract The aim of this study is to evaluate the in vitro antifungal effects of copper(II) compounds on the growth of the fungus Colletotrichum acutatum isolated from strawberry. The growth inhibition activity of Na 2 [Cu(1,3-pddadp)] . 6H 2 O complex (1,3-pddadp is 1,3-propanediamine- N,N’ -diacetate- N,N’ -di-3-propionate anion) against this fungus was compared to those of CuSO 4 . 5H 2 O and Ba 2 (1,3-pddadp) . 8H 2 O. Additionally, the effects of these compounds on sporulation level and the number of conidia per 1 mm 2 of colony were investigated. The obtained results showed that the highest percentage of inhibition for mycelium growth was achieved at a concentration of 100 and 200 µg/mL for all applied compounds. The biological activities of the investigated compounds were compared with those for the commercial formulation of fungicide captan (Metod 480 SC).
