ACGA Preview: Research in Cranberry Entomology
Join us August 15 for the ACGA Summer Field Day to visit research bogs and discuss results.
Insecticide Trials against Sparganothis Fruitworm and Spotted Fireworm
We are currently conducting experiments to compare the efficacy of various insecticides (Delegate, Altacor, Intrepid, Lorsban, Imidan, and 2 unregistered insecticides) against Sparganothis fruitworm and spotted fireworm larvae in cranberries. [Read more…]

Cranberry: Root-feeding Pests
Occurrence of root-feeding insects will manifest by the presence of dead patches. Pull dead vines and search through the root zone and soil for grubs and worms.
If your beds have damage caused by root-feeding insects, you should consider treatment with Imidacloprid (e.g. Admire Pro, Alias 4F, Alias 2F) immediately after bees are removed. Admire Pro (imidacloprid) is labeled for the control of cranberry rootworm, white grubs (Phyllophagaspp.), and other scarabs in cranberries.

Marucci Research in Cranberry: Insecticide Trials Against Blunt-nosed Leafhoppers
Semi-field bioassay testing efficacy of
insecticides on leafhoppers.
Recently we conducted an experiment to test the efficacy of a newly-registered insecticide (Closer SC) in cranberries against blunt-nosed leafhopper nymphs.
Closer (Dow Agrosciences) is an insecticide for the control of sap-feeding insects, including leafhoppers, aphids, and whiteflies. It has both systemic and translaminar activity, belongs to a new class of insecticides (the sulfoximines), and has minimal impact on beneficial organisms.
Insecticide control for leafhoppers is best achieved pre-bloom when targeting the nymphal stage, i.e., immatures. Broad-spectrum insecticides (e.g. Lorsban) are currently recommended for their control. Thus, Closer may provide an alternative to broad-spectrum insecticides and likely be more compatible with biological control because it has less of an impact on natural enemies. [Read more…]
