19/02 Control of downy mildew, black root rot and Ramularia leaf spot diseases on pansy and viola

Release Date: 
19/02/2002

This factsheet collates information from several HDC funded projects to provide guidelines for achieving effective control of downy mildew, black root rot and Ramularia leaf spot on pansy and viola. Information is provided on the recognition and basic biology of each disease to assist in the selection of the most appropriate cultural and chemical strategies for disease control. The guidelines provided aim to not only minimise the risk of crop damage by inappropriate fungicide use, but also reduce the potential for the development of fungicide resistance.
