By Top Crop Manager
June 29, 2016 - Alfalfa weevil is still at high levels in some alfalfa fields, according to the most recent Manitoba Insect and Disease Update. Some alfalfa hay fields are being cut early as a result.
Meanwhile, pea aphid levels are near or above economic threshold in some pea fields, although levels are sporadic as other fields have quite low levels.
