Late blight confirmed in 21 cases on Prince Edward Island

There are now 21 confirmed cases of late blight on Preince Edward Island, including a first-time-ever case confirmed of blight in a rogue potato plant in a soy bean field.

The majority of cases are in potato fields in the western part of the province. The soy bean field case is in Forest Hill in the east.

The potato plant would have grown from a potato left behind missed in last year's harvest.

"There is a situation this year where we have quite a few volunteer potato plants in soy bean fields. And the one in the east is in fact that,"says Marleen Clark, plant disease diagnostician with the Department of Agriculture.

While 21 cases of blight are confirmed, Clark said the number of unreported cases is probably much higher. She said the number of cases at this point is not unusually high.
