2013

We have continued to shape discussion among local government and school leaders in terms of creative response to fiscal stress.

2011 to 2013

Cornell University Cooperative Extension-NYC is co-leading a 2.5 year national project that involves approximately 60 schools in 4 States in a randomized controlled trial examining effects of school gardens on fruit and vegetable consumption and other outcomes.

2008

More than half of the world's population depends on rice as their staple food, and the U.S. is the world's fourth largest exporter of this essential commodity. Rice production must increase dramatically and in a sustainable manner to meet the demands of the 21st century. Population pressure, natural resource limitations, changing climate and globalized markets all contribute to the rapidly evolving landscape of agriculture and underscore the importance of agricultural innovation. Advances in genomic science offer new opportunities to address many of the challenges for the future.

2008 to 2013

Late blight (LB), early blight (EB) and Septoria leaf spot (SLS) are the three foliar fungal tomato diseases in temperate regions, with yearly weather conditions determining which of these diseases are most problematic that year. Currently, conventional and organic growers rely on preventative fungicides for control, with sprays typically starting in mid-July and continuing on a weekly basis. However, following release of lines from breeders at Cornell and North Carolina, seed companies are starting to trial and sell hybrid tomato varieties with tolerance to EB and/or resistance to LB.

2008

The goal of my research program is to identify and evaluate multiple strategies than can be integrated to control weeds in vegetable and fruit crops. The strategies may be traditional (chemical, mechanical) or more unusual (cover crops, natural products, weed biology/ecology, crop rotations). The intention is to develop methods of ensuring continued production of healthy foods while maintaining economic sustainability for growers and the safety of the food supply and environment.

2008 to 2011

Invasive plants change plant communities and ecosystem function across North America. My work assesses how changes in plant communities and management of invasive plants using biological control affects a wide range of native biota.

2008 to 2011

The primary focus of this project is to support the existing and expanding grape and wine industries in New York and other states east of the Rocky Mountains by increasing the abilities of grape producers and their advisers to manage infectious diseases that limit profitability and preclude sustainable production if not addressed adequately. Additionally, the project has several components that are applicable to the grape industry in the western U.S. and to those in overseas locations.

2007

Intellectual property rights for plants have increased private investment and breeder numbers. This study examines the effect on the quality of wheat germplasm in the state of Washington. Using state variety testing data, the intellectual property rights (IPR) system was found to lead to more productive varieties from both public and private breeders.

2007

By the end of the century, climate change projections under business-as-usual emissions scenarios suggest a warming of 3 – 5 degrees C accompanied by an increased occurrence of very dry and very wet periods in North America. If these forecasts are realized, agricultural systems are likely to experience an increased vulnerability to invasive weed species.

2007

The goal of this project is to identify grapevine volatile cues used by female grape berry moth, the key insect pest of grapes in the eastern United States, to locate host grapevines and use this knowledge to develop a lure and new trapping system to help grape growers monitor grape berry moth phenology and better time management decisions. We have developed a six-component synthetic lure, based on host volatiles produced by grape foliage, that is as attractive as live grape shoots in laboratory behavioral assays.
