Abstract: 
Tomato (Solanum lycopercicum L) is one of the most cultivated crops in Côte d'Ivoire. However, its production is confronted with enormous constraints, especially the damage caused by pathogens and vectors of certain diseases. Faced with this damage, most growers resort to chemical products that are harmful to the environment, the user and consumers. Therefore, it becomes necessary to use the extract of Artemisia annua as a biopesticide in the control of diseases and pests of tomato crop in the field. The trial consisted in setting up an above ground tomato crop and then formulating a biopesticide based on Artemisia annua L at different doses (100% pure filtrate; 75% diluted filtrate; 50% and 25%) and applying it on the crop. It appears from this test that the biological extract based on Artemisia annua L , proved to be an insecticide or an insect repellent and biostimulator. Moreover, the dose of 100% of the pure extract of Artemisia annua L was the best on the agromorphological parameters and on the pathogenicity parameters.
