Crop Protection Lab:
During the previous two weeks the Crop Protection Lab (CPL) received 13 plant disease samples for diagnosis, two insects for identification, two weed samples for identification, as well as 99 elm tree samples that are being tested for Dutch Elm Disease (DED). If you have a tree that you suspect has DED, get it tested! Sample submission guidelines and forms can be found at Dutch Elm Disease Testing Samples.
The plant disease samples submitted to the lab have been barley, peas, lentils, mustard and canola. Testing is being completed on some of these samples currently. Preliminary results suggest that root health issues are affecting many crops, with both fungal pathogens and oomycetes causing the diseases, the latter being found in most pulse submissions. Most canola and mustard samples had herbicide damage affecting them. There was one occurrence of a sprayer tank being improperly cleaned that led to damage on a crop sprayed at a later date. One canola plant had blackleg. If you have a sample to submit to CPL, please be sure to follow the sample submission guidelines.
