In Vitro Screening of Fungicides to Control Artillery Fungi

Abstract

We evaluated the influence of 26 fungicides at four different concentrations (0.1, 1.0, 10.0, and 100.0 a.i.) on in vitro growth of an artillery fungus (Sphaerobolus stellatus isolate SS8) in Petri plate culture. The most effective fungicides, as determined by comparison of mean EC50 values, were polyoxin-D and azoxystrobin, followed by pyraclostrobin, triademifon, tebuconazole, propiconazole, thiophante-methyl, triticonazole, thiram, and fludioxonil. These in vitro laboratory findings need to be evaluated in the field before specific fungicides can be recommended to control artillery fungi in landscape mulch.
