Overview

Randomized trial evaluates insecticides to reduce Lygus damage in carrot seed, suggesting effective control options.

Key Points

  • Evaluate the efficacy of various insecticides against Lygus hesperus in hybrid carrot seed production.
  • Conducted an insecticide efficacy trial in a commercial hybrid carrot seed field in Central Oregon.
  • Utilized a randomized complete block design with three replicates and applied treatments after honeybee removal.
  • Lygus populations were sampled using a 15-inch sweep net at 7 and 14 days after treatment.
  • Orthene fully controlled L. hesperus nymphs at both evaluation times.
  • Transform achieved significant suppression similar to Orthene at both 7 and 14 DAT.
  • Other treatments like Beleaf and Brigade showed moderate control at 7 DAT but poor efficacy at 14 DAT.
