Resumo: | This study aimed to evaluate the effect of canola extracts obtained by different forms of extraction (alcohol, macerated, watery without reservation time and infusion), in control of Botrytis cinerea in vitro and gray mold in post-harvest strawberries cv. Camarosa. In vitro condition two experiments were conducted, being mycelial growth and conidia germination in a factorial 4 X 5, with factors extraction modes and extracts concentrations (0, 3, 6, 9 e 12%), with four replicates. Post-harvest were tested four types of extracts at a concentration of 16%. The design was completely randomized, with four replicates per treatment, and the portion composed of 10 fruits per replicate. Physichocemical parameters and biochemical analyzes were evaluated. The results showed reduction of mycelial growth and conidia germination, depending on the concentrations, but there were no differences between the types of extracts. The higher efficiency of the extracts occurred at a concentration of 8,31%, the assessment within 96 hours. The alcoholic extracts, maceration and infusion reduced rots caused by B. cinerea in post-harvest strawberries. The extracts acted in changing the acidity of fruits and behavior of peroxidases, but showed no effect on total soluble solids (TSS), firmness, weight loss, anthocyanins, flavonoids and the enzyme phenylalanine ammonia liase (PAL). The results of this study demonstrate the control potential of canola in vitro B. cinerea and gray mold in strawberries.
