Research Project: WEED AND INSECT CONTROL IN CRANBERRY BEDS Project Number: 5358-22000-037-04
Project Type: Grant

Start Date: Aug 26, 2009
End Date: Sep 30, 2013

1. Develop and assess new controls for perennial weeds in cranberry beds. 2. Develop and assess controls for blackvine weevil in cranberry beds. 3. Assess organophosphate alternatives for insecticide management on cranberry beds.

Field trials will be implemented across numerous growers’ cranberry beds infested with yellow loosestrife (Lysimachia terrestris). Trials will consist of mesotrione, rimsulfuron and quinclorac applied alone and in all herbicide combinations. Research will be conducted to assess adulticides and larvicides for the control of blackvine weevil. Adulticides - each treatment will be applied at the first sign of adult emergence. Larvicides - treatments will be applied to weevil-infested cranberry beds at the end of egg laying in August. Research will be conducted to assess if any of the new alternative insecticide chemistries are as effective for fireworm control as organophosphates when applications are made via chemigation. Documents Grant with Washington State University. Formerly 5358-22000-032-15G (12/10). Formerly 5358-22000-036-04G (8/2011).
