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.

Evaluation of Potential New Insecticides and Fungicides for Honey Bee Repellency in Seed Carrots

Series/Report number: 
COARC2016
Abstract: 
To insure honey bee safety during crop pollination, potential new products were screened for bee repellency. This research was conducted in a carrot steckling field at the Central Oregon Agricultural Research Center (COARC). Bee visits were counted beginning one day after bees were brought into the field and continued for a total of four counts. There was no statistical difference between treated and untreated plots, indicating no detrimental effect on bee activity from these products.

Evaluation of Potential New Herbicides in Carrots Applied as a Directed Spray at Layby

Series/Report number: 
COARC2016
Abstract: 
Weed resistance to ongoing use of Lorox in carrots grown for seed is a concern to industry representatives and growers. This project was established to evaluate two new products compared to current industry standard treatments. Spartan (sulfentrazone) is used in peppermint production and there is local knowledge about the spectrum of weed that it is effective on. Results from a directed spray application at layby indicate that it may provide a good fit in carrot seed production.
