Wheat producers are being advised that Barley Yellow Dwarf Virus (BYVD) has been found in two wheat fields in Northwest Saskatchewan.
Crop Extension Specialist Quinton Cubbins says they did a couple of tests for the virus, which was found in the Medstead area, as it's earlier than they might normally see it.
BYD Virus is spread by aphids, so controlling their population in the field is important.
Once the wheat is infected, there are no effective treatments.
The Saskatchewan Wheat Development Commission's latest newsletter notes that the BYD Virus can cause a range of symptoms that can impact plant health and lead to significant yield losses.
One of the earliest and most noticeable signs to look for in the field is leaf discoloration, where leaves starting at the tips or edges turn yellow or red.
The discoloration usually appears one to three weeks after infection, with other symptoms being reduced tillering, delayed flowering, poor grain fill, and stunted growth.
The BYD Virus symptoms can mimic nutrient deficiencies or other diseases; as a result, lab testing is needed to make an accurate diagnosis.
To confirm that's what you are dealing with samples should be taken and sent to the Crop Protection Laboratory in Regina for confirmation.
