Preliminary evaluation of the effects of fluridone in irrigation water on container-grown azaleas

In 1992, we initiated a study to determine the effects of fluridone in irrigation water applied to container-grown azaleas. Azaleas ( Rhododendron indicum L. `George Tabor') were grown in containers with a 3 pine bark: 1 sand mixture and were irrigated daily for 5 weeks (except weekends) with s...

Description
Summary:In 1992, we initiated a study to determine the effects of fluridone in irrigation water applied to container-grown azaleas. Azaleas ( Rhododendron indicum L. `George Tabor') were grown in containers with a 3 pine bark: 1 sand mixture and were irrigated daily for 5 weeks (except weekends) with solutions containing fluridone concentrations ≤2000 g·L −1 . The threshold for appearance of visible injury symptoms (bleaching of new growth) was 250 g·L −1 at 5 and 12 weeks after treatment initiation. Visible symptoms did not appear until at least 35 days after treatments began. No statistically significant injury occurred to azaleas treated with solutions containing fluridone concentrations
