Potato late blight is a particularly destructive disease that can explode out of control from time to time, as it did in 2009 in New York. The disease is dramatically influenced by weather, host resistance and proximity to a source of the pathogen. Typically, massive amounts of fungicide are used to prevent an epidemic. We have developed a web-based system that enables a grower to control this disease but with reduced amounts of fungicide. The system is available on the web and integrates the effect of weather, host resistance, fungicide and proximity to a source of the pathogen.
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.
The implementation of manure storage covers can reduce odor and air emissions, but their management and economics are uncertain. The goal of this project is to monitor, document, and educate agricultural producers on the impact of covers on their management system and define expected costs and benefits.
Pathogenic organisms such as Escherichia coli and Cryptosporidium parvum continue to cause a threat to our food and water safety. Similarly, organisms such as Dengue virus and rotavirus are important clinical analytes related to human health, especially in the countries of the developing world. Organisms such as Bacillus anthracis and Yersinia pestis are serious threat agents for our safety and security, since they can be used as bioweapon material.
A mathematical programming model of a representative New York dairy farm is developed to identify optimal management adjustments to increased availability of corn distillers dried grains with solubles (DDGS) or a change in its relative price as the corn-ethanol industry in the United States matures.
In 2007-2008, we continued delivery of a new model for teaching science communication and outreach skills to science graduate students. In addition to delivering the course at Cornell, we helped institutions both in the US and internationally in developing similar courses and workshops.
In 2008, this study was initiated as a condition of the New York State Special Local Need Registration (SLN NY-070005) for the 4-Poster Tickicide Device (EPA Registration Number 39039-12) to investigate human and wildlife-associated risks due to changes in deer movement and behavior from placement of 4-Poster Devices and permethrin residues in and on deer, and efficacy of the technology for control of blacklegged and lone star ticks. NYSDEC issued a Special Local Need registration for application of 4-Poster Devices to reduce tick abundance on Long Island.
For the past ten years, consumers have created a demand for organic dairy products. Our project works with all links of the value chain to satisfy this demand in an environmentally, financially, and socially responsible manner.
Our team offers existing and transitioning farmers workshops to improve their farm business management capabilities. By sponsoring field days, video conferences, and discussion groups, we have allowed farmers to increase their practical knowledge of organic production techniques.
Cornell Cooperative Extension (CCE) educators are Cornell University’s front line in helping New York field crop producer clientele with crop production and pest management issues. Keeping CCE personnel informed on the latest information and developments helps us meet Cornell’s high standards for extension outreach and provides clientele with quality, pertinent, timely and user-friendly programs and resources that maximize our educational impacts.
We are designing, synthesizing, and applying new materials and properties for nanotechnological, biological, and biomedical applications. Our research has resulted in numerous peer-reviewed papers in high-impact journals such as Nature biotechnology, Nature Materials, Nature Nanotechnology, etc. More than a dozen patents have also been granted or filed. Some of these patents have been licensed to a local start-up company.
