Abstract

SUMMARY Iprodione seed treatment at 100 g a.i./kg seed had little effect on final emergence in peat‐based compost at 60% moisture content (wet weight basis) but caused up to 1.5 days' delay in the time to 50% of the final emergence (t 50 ). The effect was independent of initial seed viability, the conditions and duration of seed storage after treatment and germination temperature. Raising the compost moisture content to 70% resulted in a 9% reduction in final emergence and a 3 day increase in t 50 . Iprodione had a greater effect in a filter paper test, reducing final emergence by up to 24% and increasing t 50 ; the effects were again independent of initial seed viability and storage conditions.
