Research Projects
The Cranberry Research Foundation (CRF) funded over $12,750 in research projects in 2006. CRF makes an ongoing effort to strategically fund projects that have an immediate impact on the ability of Massachusetts cranberry growers to grow cranberries. CRF focuses on projects that improve the sustainability of cranberry production while protecting the environment. The 2006 research projects that CRF contributed funding are as follows:
Title: Transition to Biointensive Management of Cranberry Fruitworm
Principal Investigator: Anne L. Averill and Martha M. Sylvia, UMass Cranberry Station and Department of Entomology, University of Massachusetts.
Abstract: We will screen reduced-risk compounds in the lab and field. We will begin work with Cesar Rodriguez-Saona of Rutgers University to develop a trap for females and will also begin work to isolate pathogenic fungi in bog soil (which could infect the over wintering stage). Bogs that reported high losses to cranberry fruitworm in recent years will be monitored to determine contributing factors to control failure.
Title: Black-Headed Fireworm and Winter Moth: Evaluation of pest status
Principal Investigator: Anne L. Averill and Martha Sylvia, UMASS Cranberry Station and Department of Entomology, University of Massachusetts Amherst
Abstract: Sampling and management approaches will be evaluated for black-headed fireworm. This includes screening of compounds, assessment of larval sampling and trapping efficiency, determination of a partial or complete third generation, and potential of biological control impact. Winter moth pest status will be assessed in bogs at risk.
Title: Efficacy screening a new herbicide on woody perennial weed species
Principal Investigator: Hilary A. Sandler
Abstract: This new herbicide has excellent efficacy against nut sedge and some grass and rush species. In addition, cranberry exhibits excellent tolerance to the herbicide. Observations in 2005 indicated injury on woody perennial weed species that came into contact with herbicide drift from adjacent studies. The focus of the proposed study is to evaluate several rate regimes of the new herbicide for control of sawbrier (Smilax glauca) and dewberry (Rubus sp.) in controlled studies. If possible, we will also evaluate efficacy of this exciting herbicide for control of yellow loosestrife (Lysmachia terrestris) and narrowleaf goldenrod (Euthamia tenuifolia) and other problematic cranberry weeds.
Title: Potassium rates and timing for optimum cranberry nutrition
Principal Investigator: Carolyn DeMoranville, UMass Cranberry Station
Cooperators: Joan Davenport, WSU; Teryl Roper, UW Madison, MA cranberry growers.
Abstract: As growers’ ability to use custom blended fertilizer increases, questions surrounding the amount of potassium fertilizer that is optimum for cranberry production have increased. Although normal ranges for cranberry tissue K are established, and some recommendations exist for K rates, primarily Extension recommendations have focused on N and P. The research presented here also proposes to complement field and laboratory studies in WI and WA so as to define the optimum K rate, timing, and form for cranberry production. This will allow growers to make informed decisions regarding fertilizer blends and potentially lead to cost savings. The primary concern leading to this proposal is a recent study from WI showing that despite grower conviction that high K rates are required, there may actually be a negative relationship between yield and high tissue or soil test K values (WI cranberry School 2006).
