Chemical control of Fusarium head blight on wheat.

The effects of different chemical substances on infection and mycotoxin production by Fusarium culmorum in winter wheat cultivars were investigated in field trials during two years. Spray treatments of the cvs. Kontrast and Agent with the fungicide tebuconazole either two days before or two days post – inoculation reduced of the disease index of the spikes by 61 – 89% and the DON in the grain by 50 – 70%. Application of melconazole in the cvx. Kontrast, Agent and Piko two days before inoculation led to decreases of the disease index by 68 – 71% and the DON content in the grain by 61 – 69%. Application of the fungicidal substance chlorothalonil, prochloraz and benomyl  two days before inoculation did not satisfactorily control the pathogen. Treatment of the plants with azoxystrobin reduced the disease index of the spikes, but the DON content of the grain was higher than in the untreated control. Application of piperonylbutoxide, a possible inhibitor of trichothecene biosynthesis, increased the efficacy of the fungicides in the cv. Agent.
