Botrytis cinerea is causing fruit rot of strawberry after infection of flowers and fruits by
airborne conidia. The antagonist Ulocladium atrum has been selected for its ability to compete with Botrytis spp. in necrotic tissues. Antagonism results in suppression of sporulation of the pathogen and in blocking growth of B. cinerea from necrotic plant tissue to adjacent healthy tissue. Preliminary experiments in strawberry demonstrated the potential of U. atrum to suppress B. cinerea sporulation on strawberry leaves as well as to protect flowers from invasion by the pathogen. A series of ten field experiments has been carried out with annual waiting-bed crops between 1996 and 2003 to optimise and to integrate the use of U. atrum in control of grey mould in such a strawberry cropping system. First experiments indicated that applications before flowering did not increase disease control and that regular applications twice weekly during flowering were superior to applications once weekly. In 2002 and 2003, a decision support system was used to optimise timing of antagonist applications and to avoid applications under conditions not favourable for disease development. In comparison with regular applications of U. atrum twice weekly, applications according to DSS (>7.5% infection chance) were less frequent resulting in slightly weaker disease control (2002; no statistically significant difference) or timed differently resulting in increased disease control (2003).
