Insect Management: During September and October 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 (picture), 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, but are most common as pests in re-seeded fields. The palestripped 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.
Weed Control: Eptam 7E was the first herbicide registered for
water-run applications. It is also available as a 20% granule. The granular
formulation is often a more efficient way of applying this highly volatile
herbicide as long as it is incorporated with water within 12 hours. Because
the granule is more efficiently applied than water-run 7E application,
2 lbs. active ingredient of the 20G is often equivalent to 3 lbs active
ingredient of the 7E
