Insect Management: During September many growers will
be establishing new stands of alfalfa. Several insect pests can be of
concern during stand establishment. When seedling alfalfa plants have
emerged monitor the stand for clipped plants. Cutworms, crickets and earwigs
will occasionally be abundant enough to severely thin stands by clipping
alfalfa seedlings. Sowbugs and pillbugs are crustaceans that damage seedling
fields that have not been well tilled and have been known to cause damage
in re-seeded fields. The palestriped flea beetle is also occasionally
abundant enough to cause severe damage to seedling alfalfa. Treat with
an insecticide bait or foliar insecticide when these insects are abundant
enough to cause areas of stand loss.
