Resumo
With the objective of studying the effect of some syst! mie drugs on the fungus, Fu-6a.1t.i..um ox.y-6po1tu.m f. sp. cuben-6e (Ef.) Sn. EH., which attacks the rootstalk tissue of the cultivated "Maçã" bananna (Mtua. -6ap..ie.n.tum L. l, an experiment was set up in virgin "cerrado" soil, which had been previously covered with natural vegetation. The effects of Benlate (benoniyl) and Plan tvax (oxamyl), both in doses of 0.1, 0.2, and 0.5%, as well as Mycostatin (nistatina) in doses of 0.02, 0.05, and 0.1%, and co bination of Mycostatin plus soluble Neantina (chloride of metoxi-etil mercurio at 3 1 7%) in doses of 0.02, + 0.15%, 0,05 + 0.3%, and O. 1 + 0.5%, were tested by immersing the infected roorstalks in the solutions for a ten-minute period. The rootstalks used had been naturally infected by the fungus. lhe experiment design used was randomized blocks with four (4) repetitions of twenty-six {26) treatments. Each parcel was composed of four (4) plants.
lhe results observed in February of 1974 revealed an i discriminate incidence of the ''Mal do Panama• on the plants of all treatments, demonstrating that none of them was sufficiently effective in erradicating the pathogen established in the rootstalk tissues. It is suggested, because of root damage and the subsequent inadequate penetration by the fungicides, that this lack of absorption was responsible for the unsuccessful attempts at controlling the disease.
It was concluded that the control of this disease is neither possible nor viable under the conditions in which the ex periment was executed, using the above-mentioned method of fungi cide application and preparation of the rootstalk. Changes ;; procedure are recommended for future experiments.
