Interpretive Summary: Several chemicals were tested in the laboratory and greenhouse to see if they were effective in killing strawberry rootworm adults. All chemicals (DeltaGard, Scimitar, Discus, Orthene, Tame, Decathon, Talstar and Pylon) killed the adults. Growers will be able to use this information to make more information decisions about which chemicals to use to control this nursery pest.
Technical Abstract: In the lab and greenhouse DletaGard GC 5 SC at 4 and 8 fl oz/100 gal, Scimitar GC at 2.5 and 5 fl oz/100 gal, Discus at 25 and 50 fl oz/ 100 gal, Orthene TT&O Spray97 at 16 oz/100 gal, Tame 2.4 EC at 10.7 fl oz/ 100 gal, Mavrik Aquaflow at 10 fl oz/ 100 gal, Decathlon 20 WP at 1.9 oz/100 gal, Talstar Nursery Flowable at 10 fl oz/ 100 gal, and in the laboratory trial only, Pylonm at 2.6 fl oz/ 100 gal were tested against the strawberry rotworm adults. In the greenhouse the 8 oz. Deltamethrin and 5 fl oz Scimitar treatments effectively killed beetles as quickly as one day after treatment. The laboratory trial demonstrated that all treatments with the exception of Mavrik killed 96-100% of strawberry rootworm adult beetles by the end of the trial, 7 DAT.
