Propagator's Cornucopia: Products, Problems, and Observations

摘要

This presentation deals with several topics that are the results of observations in the field, production, and landscape situations. It is my intent to share with you these various topics and that this information may be of use to you in your own particular situation. This past year, 2001, was one of unusual weather here in the Chicago metropolitan area. The summer weather was very conducive to a number of fungal and bacterial diseases. As a general practice I have for many years rotated use of several different types of fungus-control products to deter a resistance build up in either a growing or garden situation. I realize this is not a new tactic, but I wanted to share with you what products and results I had this past year. Prior to the onset of blackspot, Diplocarpon rosae, I began a program to control potential disease outbreaks in several large (50 to over 100 plants) rose garden collections.
