  Effect of Late Winter 1998 Furadan4F Alfalfa Stubble Treatment on Alfalfa Growth and Alfalfa Weevil, Aphid, and Threecornered Alfalfa Hopper Populations

  Rethwisch, Michael D.; Kruse, Michael; Ottman, Michael J. (College of Agriculture, University of Arizona (Tucson, AZ), 1999-05)

  Furadan 4F was applied to alfalfa regrowth stubble following the first harvest of 1998 to examine treatment effects of alfalfa weevils, aphids, resultant plant growth, and threecornered alfalfa hoppers. Furadan 4F reduced larval numbers throughout the period that larvae were present (25 days after treatment). Little effect was noted for adult weevil numbers in field. Aphid numbers were also reduced by the treatment, and alfalfa stems in Furadan 4F plots were significantly taller at 21 days post treatment. Little, if any, effect from the Furadan 4F treatment was noted for adult threecornered alfalfa hopper populations during the five months following application.
