University of Missouri Plant Clinic
Cool wet weather may result in an increase in plant disease problems this spring, particularly fungal and bacterial diseases that thrive during these conditions. After last spring’s unusual freeze, as well as droughts, flooded soils, ice storms and other stressful environmental conditions over the past few years, we may also see an increase in other plant stress related problems including root rots, cankers, insect infestations such as bark beetles and borers, and other issues. Recently in the diagnostic clinic we have received an influx of samples that have been submitted from severely stressed pines and other conifers that have turned yellow and brown over the winter. In some cases the problems are related to environmental conditions and little can be done to save the tree. In other cases treatable diseases are present. Proper disease identification and careful timing of treatment applications can make a difference in protecting susceptible plants from damage, especially in a year with favorable conditions for disease development. The time for treatment applications for some of these diseases may occur within the next few weeks.
Sample submission to the diagnostic clinic can provide you with an accurate diagnosis of your plant problems and management recommendations. Please refer to the sample submission section of our website http://soilplantlab.missouri.edu/plant/index.htm or contact us for more information on sample submission.
