Crop Protection Lab:
During the previous two weeks the Crop Protection Lab (CPL) received 17 plant disease samples for diagnosis, and one weed sample for identification, as well as 82 elm tree samples that are being tested for Dutch Elm Disease. 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 garlic, cereal crops, oilseed crops and pulse crops. Testing is being completed on these samples currently. Preliminary results suggest that root health issues are affecting many crops. The CPL has also had two positive cases of Wheat Streak Mosaic Virus occurring in wheat crops. There has been a few incidences of herbicide carryover injury identified, and one occurrence of a sprayer tank being improperly cleaned that led to damage on a crop sprayed at a later date. If you have a sample to submit to the lab please be sure to follow the sample submission guidelines.
