“We don’t have a concrete number but it’ll be in the thousands of acres,” Greg Donald, president of the P.E.I. Potato Board, told Farms.com today.
Mustard helps control wireworm, which causes about $10 million worth of annual crop damage in P.E.I. by burrowing holes in potatoes and making them unfit for sale.
Instead of harvesting the mustard, farmers work the crop into the soil. As the mustard breaks down, it releases a biofumigant that controls wireworm and similar pests.
The crop also has other advantages, said John Hogg, a 2,000-acre potato and grain producer from Summerside, P.E.I.
“If you incorporate the mustard into the soil it can have some weed control benefits,” he told Farms.com today. “It can also be good for soil health overall. We’re just waiting for documentation to give us firm results.”
Some farmers have also found potato yield benefits after a mustard crop.
Those boosts are a result of mustard’s ability to fight off several pests and diseases, said Ryan Barrett, research coordinator with the P.E.I. Potato Board.
“In potatoes we battle quite a few soil-borne fungi like rhizoctonia and common scab, which can affect skin finish on potatoes,” he told Farms.com today. “We’re definitely seeing some growers with yield boosts and we think part of that is mustard’s ability to manage these kinds of diseases.”
A good crop rotation can help break up disease cycles and promote microbe development in soils, Barett added.
