Abstract : Studies were conducted to evaluate the use of essential oils of different basil genotypes as a form of alternative control of stem end rot of mango caused by Lasiodiplodia theobromae. In vitro, the oils were tested at different concentrations and evaluated over time in order to compare their performances as antifungals. The basil genotype B was the most effective and was selected for the in vivo test, which was tested using a small concentration fungicide used in the in vitro assay. The infection rate was assessed in 2 ways, i.e. curative and preventive. Results showed that the highest efficiency was observed in the curative treatment.
