After the 2 nd treatment(May 9) the results are significant (b) invariants 2 and 3 and significant distinct (bc) invariants 4 and 5 and very significant in variant6. The results obtained after the 3 rd treatment(June 12) are from distinct significant in84variants 3 and 5 up to very significant in variant6.It results that the following contact fungicidesBravo 500 SC and Dithane M 45 (V2 and V3)have a good efficacy, and the systemic ones(V3-V6) present a high efficacy. The bestresults were obtained with V6, the fungicideScore 250 EC.CONCLUSIONSDuring the laboratory trials there were selectedthe products with the best biological activity
