A preliminary conclusion is that the herbicide addition increases the numbers of 2,4-D degrading and total bacteria counts and that plants don’t influence 2,4-D degradation by indigenous microflora or bacterial counts. However, a more exhaustive study is nowadays being performed in order to correlate the herbicide dissipation with bacterial counts and to deep explore the plant-bacteria interactions. Evaluating the capability of herbicide degradation by soil microbes and the factors that influence on it is a necessary step for future design of bioremediation strategies.
