Evaluation of Potential New Insecticide in Carrots for Lygus Control

Series/Report number: 
COARC2016
Abstract: 
Lygus bugs feeding on carrots grown for seed during flowering and seed maturation reduce seed viability. Potential new insecticides for control of lygus in carrots were evaluated in alfalfa and carrots plots at the Central Oregon Agricultural Research Center (COARC). Sulfoxaflor (Transform) and flupyradifurone (Sivanto) were compared to the industry standard, naled (Dibrom 8) plus lambda-cyhalothrin (Warrior II) and an untreated check. Although Transform was effective one week after application, Dibrom 8 plus Warrior II was the only effective treatment compared to the untreated check in subsequent evaluations and across the three sampling dates.
