The plum curculio is an extremely destructive key pest of stone and pome fruit in commercial orchards in eastern North America. In fact, in a survey of over 100 MA and RI apple growers (conducted in mid-April 2018 by J. Piñero) this insect pest ranked first in importance. Conventional growers typically apply broad-spectrum insecticides to control plum curculio. The main goal of this project is to evaluate the attractiveness of aromatic compounds to overwintered plum curculio and to other early-season pests.

Experiments will be conducted in the greenhouse and in the field with leafy vegetables to investigate if the mineral nutrient content of these foods can be enriched through fertilization of the crops. This research will address investigations of mineral nutrients, suggested to include phosphorus, calcium, magnesium, potassium, iron, manganese, copper, and zinc, which the investigators have the capability of analyzing in their laboratories. The research will emphasize investigations with lettuce that can be cycled rapidly in greenhouse or field production.

The goals of this project are to: 1) study and improve microbial control options in IPM strategies for: a. arge acreage crops (alfalfa, corn, dry beans, potatoes, and small grains) b. orchard systems (fruits and nuts) c. small fruits and vegetables (blackberries, blueberries, raspberries, strawberries, and vegetables) and d. urban and natural landscapes, rangelands, and nurseries.

Grapes have a high establishment cost of $20-30K/acre and delayed returns during a 3-4 year establishment period. Profitability and sustainability depends upon reliable productivity and resilience to inevitable climate-related injury.

Wetland identification, protection, and restoration is a multi-million dollar industry in the United States. State, regional, and federal agencies are working to develop and enforce regulations to maintain, enhance, increase, and protect our nation's wetlands. Non-profit organizations such as The Nature Conservancy, Sierra Club, World Wildlife Fund, and Ducks Unlimited have joined forces to support many of these efforts. In contrast, economic development can be stymied by over-regulation and thus developers argue for a balance between natural resource protection and development.

The overall objective of this research is to use beneficial bacteria and fungi to improve medicinal and aromatic plant yields quantitatively and qualitatively. Specific objectives are:
