Traditional herbicides are glyphosate based. Overuse of these herbicides has led to glyphosate resistance in some plants. Amaranthus palmeri is one of them. This study is an ongoing one whereby we investigate the responses of the Glyphosate Susceptible and the Glyohosate Resistant forms of Amaranthus palmeri to organic acetic acid herbicides. First, we hypothesized that although they respond differently to glyphosate based herbicides, they will both respond the same to organic based herbicides. When both are treated in a greenhouse with an organic 10% acetic acid solution, and are under 8cm in height, both die. This low 10% acetic acid solution was used versus the standard 20% acetic acid solution, because previous studies suggest that at a very young age, the 10% solution is strong enough to control the growth. Using less solution is less costly to the famers pocket and to the environment. Death did occur with both plant forms. However, there is a slight difference in death rate. With the Glyphosate Susceptible plants, 85% died within 24 hours, while with the Glyphosate Resistant plants 100% died within 24 hours. Because of this slight difference, we are now investigating genomic data. There may be changes in the genomic response between the Glyphosate Resistant forms of Amaranthus palmeri versus Glyphosate Susceptible forms of Amaranthus palmeri to an organic herbicide solution that contains 10% acetic acid. We wish to see if these two plants will have the same genomic response to this treatment or if the response will be different. We are collecting samples of Glyphosate Susceptible and Glyphosate Resistant Amaranthus palmeri in their early stages of growth that have been treated with 10% acetic acid. We are looking at changes that may occur immediately, within 4 hours, within 8 hours and/or within 24 hours of treatment. Most herbicide damage to cells will occur within 24 hours.

Role: My role in the research included planting pants and harvesting their growth. I worked with pots, soil, and gardening to tools to structure our control and treated plants. I monitored their nutrient intake for maximum growth. I also contributed in collecting the plant specimens.
