Effect of planting time on the incidence of crown rot (Gibberella zeae) in wheat

Abstract

In the time pf planting experiments with wheat conducted from 1963 1967 on the Darling Downs in QLD, late sowing always produced much less crown rot than early sowing. Although seed inoculated with a spore suspension of the casual fungus (Gibberella zeae) produced a higher percentage of diseased plants. The relation between time of planting and disease incidence was not disturbed. No direct relation between temperature or rainfall and disease incidence was apparent.
