Horticulture requires a significant use of chemical inputs due to the parasitic pressure to which it is exposed. Among these inputs are the herbicides that are the most used. Due to their mode of action and their selectivity, those based on 2,4-D, glyphosate and nicosulfuron are detected as being the most widely used. This massive use is not without consequences on the environment and particularly on soil. Herbicides are frequently implicated in the reduction of soil fertility and terrestrial biodiversity observed in agricultural areas. This situation requires the greatest caution and clear information on the environmental risks actually incurred by in situ studies. This study was initiated with the aim of evaluating the impact of herbicides on soil life by using Eudrilus eugeniae earthworms as bioindicators. To do this, each experimental plot on which microcosms of earthworms were deposited received a herbicide treatment based on 2,4-D, glyphosate or nicosulfuron at the concentrations recommended by the manufacturer. Parameters such as biomass, number of cocoons, hatching rate and number of individuals per cocoon were evaluated. After 35 days of exposure, no effect was observed on the biomass of earthworms. Reproductive parameters such as number of cocoons, hatching rate and number of individuals per cocoon were strongly reduced by 2,4-D herbicides. Those based on glyphosate and nicosulfuron only reduced to lesser degrees the number of cocoons laid per pair compared to 2,4-D. The acute avoidance reaction test was a function of the herbicide and its concentration used. At the end of this study, it appears that the treatment of 2,4-D, glyphosate or nicosulfuron at the manufacturer's concentrations poses a threat to the specific richness of earthworms; they therefore reduce soil fertility. Those based on 2,4-D exhibit severe toxicity to soil health.
