Diagnosis at the Crop Protection Lab is in full swing. See what the most common issues have been this year.
The recent rains have helped crops progress and resulted in an influx of samples at the Crop Production Lab. To date, 56 samples have been received, which is fewer than at this time in 2018. The main concerns have been related to environmental stress, including low temperatures earlier in the spring followed by high temperatures and moisture stress.
A couple of recent canola submissions were diagnosed as having brown girdling root rot and wire stem symptoms resulting from infection caused by Rhizoctonia solani.
Herbicide carryover and root rot complex have accounted for a number of samples.
In addition, the Lab has received 73 samples for Dutch elm disease testing. There have been seven confirmed negative samples tested for Dutch elm disease, with the other results still pending. The Lab also wrapped up the herbicide resistance testing from 2018 submissions, with 363 tests completed.
In some recent news, the Crop Protection Lab will be moving in fall 2019. The new location will still be in Regina. Further information will be forthcoming.
