Prairie growers should be checking their alfalfa fields for alfalfa weevils as soon as possible, say forage experts in Manitoba and Saskatchewan.
If weevil larvae numbers are high, the alfalfa crop should be cut immediately, weather permitting.

“There are many alfalfa fields where if it’s not hayed or sprayed, very soon, there will be quite significant damage,” said Lorne Klein, Saskatchewan Agriculture’s forage specialist in Weyburn, Sask.
