Scouting advised for alfalfa weevil CONTINUED FROM PAGE C2
Economic Thresholds Economic thresholds have been developed to aid decision making on alfalfa weevil control (Table 1). These thresholds were derived by North Dakota State University entomologists (Beauzay et al. 2013) from a two-year study conducted at the UNL Eastern Nebraska Research, Extension and Education Center near Mead in 1990 and 1991 (Peterson et al. 1993). These guidelines can fluctuate depending on growing conditions and variety. Deciding whether to treat or re-sample depends on the average number of weevils per stem, the stem length, treatment costs and the value of the alfalfa. When alfalfa reaches 50% or more bud stage, it may be more profitable to cut the alfalfa early than treat it. Insecticides Because alfalfa weevil natural enemies (e.g., lady beetles and parasitoid wasps) have the potential to keep weevils from reaching economic injury levels, use insecticides only when necessary. Many insecticides are registered to control alfalfa weevil larvae. See the most recent edition of the Guide for Weed Management in Nebraska with Insecticide and Fungicide Information (EC130) for rates and restrictions of commonly used insecticides for alfalfa weevil larval control. They differ in their modes of action and pre-harvest intervals. Highly effective insecticides for alfalfa weevil control include those that are pyrethroids (active ingredient ends in “thrin”) and products containing indoxacarb (e.g., Steward). Pyrethroid insecticides also provide aphid control but can have detrimental effects on beneficial insects. Indoxacarb products are more selective and do not affect most beneficial insects but will not provide aphid control. Recent concerns of insecticide resistance have been noted for lambda-cyhalothrin (e.g. Warrior) as well as indoxacarb (e.g., Steward) in various field reports throughout western states. However, recent laboratory studies of field-collected alfalfa weevil populations for low desert regions of California and Arizona (Mostafa and Harrington 2020) have indicated no measurable resistance to populations in those locations. It is important to note that because of complications due to overwintering of multiple life-stages of this insect, control failure within a region could be the result of insecticide resistance or it could also be due overwinter survival of mixed life stages as discussed under “life stages” above.
Wheat grazing vs grain value
By Todd Whitney, UNL Cereal grains like wheat are grown for dual purpose (forage and grain) production in the central plains and southern plains states. To prevent grazing animals from eating immature wheat heads, livestock are generally removed from the fields just prior to the jointing growth stage when immature wheat heads move up the stems. This year, economic conditions and the marginal wheat yield outlook have many Nebraska growers placing higher value on wheat as a forage. Extended spring dry conditions held back pasture growth and delayed livestock turn out onto native pastures. Also, higher hay prices (still over $200 per ton for prairie hay and baled alfalfa) are favoring wheat forage utilization. For example, the wheat or rye graze-out option may provide 45 days or more of grazing. So, instead of protecting potential grain yields, producers may be removing wheat as a forage and re-planting summer annuals like grain sorghum, millet, or forage sorghums on those same fields. Whether the cereal plant forages are grazed-out; hayed or harvested as wheatlage; the goal is to timely plant subsequent summer annuals between midMay to mid-June for optimizing yields. Sorghum planting windows may extend to later June or possible early July depending on moisture conditions. Later grain sorghum planting dates, though, such as after wheat grain harvest usually result in yields half as productive compared to earlier sorghum planting. In western Nebraska, average stocker cattle gains on wheat during May and early June have ranged from 1.5 to 2.5 pounds per head per day. ##### In the 2004 movie “Mean Girls,” the “nice girl,” Cady, is named after Elizabeth Cady Stanton, a 19th-century pioneer in the American women’s rights movement.
