Integrated Preharvest Fungicide Programs for Brown Rot
There was a time when selection of a fungicide for brown rot control was based solely on efficacy and cost of the product. However, the brown rot pathogen, Monilinia fructicola, has become resistant to DMI fungicides and to some extent QoI fungicides in many stone fruit growing regions in the eastern United States. This occurrence has underscored the need for a greater degree of integration of different fungicide chemistries as a resistance management strategy. [Read more…]

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…]

Cranberry: Insect Update 6/28/2013
As we approach the end of bloom, growers should consider the need for any post-bloom applications. The main pest targets for these applications are mainly Sparganothis fruitworm and spotted fireworm. [Read more…]
