Copper(II) compounds as effective agents against Colletotrichum acutatum causing strawberry anthracnose
Abstract
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 Na2[Cu(1,3-pddadp)].6H2O 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 CuSO4.5H2O and Ba2(1,3-pddadp).8H2O. Additionally, the effects of these compounds on sporulation level and the number of conidia per 1 mm2 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).
