Biology, Etiology, and Management of Dollar Spot in Turfgrasses

Managed turfgrass areas (golf courses, lawn care companies, sport facilities, others) are vastly important for businesses in the New England economy. Intensively managed areas on golf courses, in particular, are challenged by abiotic and biotic (mostly by fungi) stresses that require monetary investment for maintaining optimal appearance. Dollar spot disease (caused by plant pathogenic fungi) is one of the most economically challenging pathogens, requiring repeated chemical inputs annually to maintain acceptable playing surfaces.

WC1 Hybrid Co-receptor/Pattern Recognition Receptor in the Immune Response to Pathogens of Domesticated Animals

Animal health is of great importance, in agricultural, food security, general economic and public health terms. The diseases that our lab investigates (e.g. tuberculosis, anaplasmosis, Johne's disease, leptospirosis, and porcine reproductive and respiratory syndrome virus (PRRSV)) cause billions of dollars in losses to U.S. agricultural producers. In addition, tuberculosis,anaplasmosis, leptospirosis and Johne's disease are zoonotic diseases, in which animals can serve as reservoirs and vectors of often fatal diseases for humans.

Improving Forage and Bioenergy Crops for Better Adaptation, Resilience, and Flexibility

As the global human population continues to grow and climate change alters weather patterns and intensifies stress on agricultural systems, we need to find new ways to sustainably increase production agriculture. We focus on grasslands because they are important for global food stability and as a vast ecosystem (66% of agricultural areas are grass lands) have serious global climate implications.

Novel Species Interactions: Effects of Invasive Plants on Butterflies, Birds, and Soil Biota

A focal species of this work is the widespread invasive biennial plant, Alliaria petiolata (garlic mustard) which disrupts nativeplant-fungal interactions in Northeastern deciduous forests of North America. Unique plant chemicals exuded by the roots ofgarlic mustard disrupt symbioses between native plants and mycorrhizal fungi that live on their roots (Stinson et al., 2006), alterthe diversity and composition of the soil microbiome (Barto et al., 2012; Anthony et al.

Development and Physiology of the Stomatal Complex in Grasses

Water is an increasingly scarce resource for agriculture thus engineering plants that use water efficiently is a primary goal forscientists. A recent approach in achieving water-efficient crops is to breed or engineer plants that can rapidly open and close their stomata in changing environments (Lawson and Blatt 2014, Raven 2014). During the day, plants may become shaded or enjoy a sudden but transient increase in sunlight as sun angles change (or are reflected) or as clouds and/or other obstacles block the sun.

MDAR Acidified Canned Food Products

Producing shelf-stable acidified canned foods can help to add value to produce and introduce new markets, extend the agricultural season, and reduce waste. However, to successfully sell and distribute shelf-stable products, such as salsas, sauces, and/or acidified pickled products, processors must comply with the Code of Federal Regulations (21CFR114).

Improving Access and Motivation for Small and Medium Processors in the Northeast to be in Compliance with FSMA’s Preventive Controls Rule

Many small and medium producers and processors are affected by the recent implementation of the Food Safety Modernization Act (FSMA) regulation as the existing training does not address how to determine compliance and assumes that small and medium food processors (SMPs) begin training with a base level of food safety knowledge that many SMPs do not have. This project develops accessible, scale-appropriate, motivational mixed-media content to provide SMPs with the information they need to better understand how to implement Preventive Controls (PC) in their food businesses.
