DiTommaso, Antonio

Associate Professor
The overall goal of my research program is to study and gain a more in depth understanding of the basic biological/ecological principles governing agricultural and environmental weed population dynamics that ultimately lead to the development and implementation of safe, effective, sustainable and economically viable weed management strategies. To achieve this goal my research program comprises several major thrusts.

research and scholarship focus

Primary areas of scholarship focus on:||Effects of the environment on weed species. Evaluation of the effects of biotic (e.g. plant competition; selective disease and insect predation) and abiotic factors (e.g. light, fertility, salinity) on the seed biology, growth and reproduction of important agricultural weeds (velvetleaf, pigweeds, common ragweed) and introduced invasive plant species (e.g. swallow-wort, mugwort) of natural communities in the Northeastern United States.|Effects of weeds on their environment. Examination of the direct and indirect impact of weeds in their habitat. Includes research on the effect of the invasive alien vine pale swallow-wort (Vincetoxicum rossicum) [Apocynaceae] on monarch butterfly populations, arbuscular mycorrhizal fungal (AMF) populations, and native plant species. |Manipulation of the environment to suppress weeds. Research aimed at modifying the biotic and/or abiotic environment of troublesome weeds in both cropland and natural systems to improve control. These tactics can be used either alone or as part of an integrated management strategy. Manipulation of the biotic environment is primarily achieved through the use of selective biological control agents such as fungal pathogens and insects while abiotic manipulations focus largely on soil fertility management.

teaching

teaching focus

My teaching philosophy is founded on respect both for students as individuals and for the pedagogical process. My approach is based on the following belief: As students become active observers, they will be motivated to seek and learn new ways to discover, problem-solve, collaborate, and develop critical thinking. Thus, it is my role and responsibility as a teacher, to seek ways to stimulate, encourage, and enhance students` curiosity. ||Undergraduate Courses Taught:|CSS 315 - Weed Biology & Management - (Fall term) 4 credits. ||ENTOM/CSS 444 - Integrated Pest Management (Fall term) - 4 credits. |Course website: http://instruct1.cit.cornell.edu/courses/ipm444/||Graduate Courses Taught:|CSS 614 Weed Ecology and Management (Spring term) - 3 credits - offered in odd years only.
