Nursery, Greenhouse, and Landscape - New Fungicide Available

The following is information on a new fungicide available for the green industry from Bob Mulrooney, Extension Plant Pathologist, UD.

A new fungicide has been labeled for use on turf and ornamentals in greenhouses, shade houses, container nurseries, retail, conifer and forest nurseries, commercial and residential landscapes, and interiorscapes. It is called Pageant. Pageant from BASF is a combination product of pyraclostrobin (Insignia) and boscalid (Emerald). Those of you that know the vegetable and fruit fungicides will recognize Pristine which is the equivalent combination in Pageant.

I have tested it for powdery mildew and black spot control on hybrid tea rose and found it to be pretty effective at the high rates for black spot but not very effective on powdery mildew.
Trial results are below.

It has a wide label and could be very effective for the diseases on the label. You beed to check the labels for plants with sensitivity such as some grape cultivars, ninebark and Wintercreeper , Euonymus vegetus.

The label can be found at
