Strawberry culture is one of the most difficult when it comes to the biological control of fungi. The use of plant extracts as an alternative control to minimize the incidence of persistent fungi in crops or planting areas has been researched in recent years, in the search for more natural control and less harmful to the environment and human health. The objective of this work was to verify the effect of the extracts of the plants, losna (Artemisia absinthium L.), arruda (Ruta graveolens L.), pimento-longa (Piper aduncum L.) on the biological control of the fungus Botrytis cinerea. The extracts were prepared by extracting the crude extract of the plants, diluted in ethanol-based solvents, dosed at 0 (control or control), 25g.L-1, 50g.L-1, 100g.L-1, 12 treatments, 5 replicates and 10 plants. Among the results obtained, we highlight the concentrations of 100g.L-1 for the extracts of Piper aduncum L. with significant effect on the control of Botrytis cinerea fungi with significant decrease of the presence and infestation in plants as in fruits.
