Abstract
Pesticides have been an important building block in the process of agriculture for hundreds of years now. However, over time the danger of certain pesticides has become clearer and clearer. These striking studies commonly revolve around the active ingredient involved in the pesticide, and the most dangerous of these active ingredients: glyphosate. Shockingly, due to its affordability, glyphosate is the most commonly seen active ingredient in pesticides, even with it's danger being known. An alternative is needed. Naphthaleneacetic Acid, an auxin, has demonstrated an uncanny ability of pacificity when placed in the same enviornment with a microbiological organism. In addition to this, naphthaleneacetic Acid is efficient at reducing plant growth on a small and large scale. A model organism that can be negatively affected by glyphosate is Pseudomonas fluorescens.: a beneficial microorganism that inhabits the soil. The growth of P. fluorescens can be measured using zone of inhibition (ZOI). The testing of Glyphosate on P. fluorescens revealed an average ZOI of 5.587 cm, in comparison to the testing of naphthaleneacetic acid on P. fluorescens which revealed an average ZOI of 0.747 cm. When placed in a solution of naphthaleneacetic acid, P. fluorescens demonstrates minimal inhibition, however when placed in a solution with Glyphosate, the growth of P. fluorescens was completely halted.
