Positive physiological effects of using some systemic fungicides in horticulture were meansured. Some effects were observed, growth increased and vegetal development, what directly interfered in the final production. In this way, this study ainmed at examining how the application of some systemic fungicides influenced in the agronomic characteristics. For that these fungicides were administered on crop Brassica oleracea L. var. botrytis L, cv. Barcelona. The experiment was performed with randomized complete block design, with four trataments (T1) control without fungicide application, (T2) Cantus 0,3 g L-1 , (T3) Cabrio Top 3,0 g L-1 , T4 stimulate 0,6%) and 4 replicates. Each parcel was represented by 20 plants, with fungicide application at two times the first at 20 days after sowing in the trays and the second at the beginning of the flowering on the field crop. With regard to the number of leaves per plant, the treatment that presented the worst result was (T4) in which there were on difference on treatment. The treatment with boscalid resulted in bigger and heavier inflorescenses standing out production over the other treatments. It presented positive results in the final production, which was one of the main expected factors. Followed by the treatment in which Piraclostrobine (T3) was used, witness (T1), respectively. The treatment that presented an inferior result in all the analyzed elements was (T4), with Cinetine 0,09 g/L + Giberelic Acid 0,05 g/L (GA3) + Ácido 4-indol-3ilbutírico.
