Frequently the incldence of damping • off in the seedbed, in pre or post-emergence, affect the chronogram of planting, causing death of thousands of pla􀀄 tules. ln the present experiment, it 􀂤as attempted to determi­ne the effect of seven fungicides, app11ed by spray at high v􀀅 lume, on the contro1 of damping • off caused by Cy.V.-nd1r..octad.iun sp. and Fu..6alU..um sp. in plantules of Eucatyptu..6 􀃜a.U.gna Sm. in the seedbeds. The experimental design used was that of random 1 blocks with four {4) repetitions. lhe seeds were desinfected with dry Neantine at 0,31 and the seedbed was treated with methyl brom1de (40ml/m2 ), and afterwards innoculated with Cy­t.ind1r..octad.ium sp. and Fcu,a/U.um sp. grown in substrate cornaeal -sand. It was observed that the most effective treatments in the control of damping - off were Arasan - 75 at U,3S, Cupravit azul at 0,4% and Mtltox at 0,35% 1 while the most phytotoxic aspect 1n the parts treated with Ferrado! at 0,251. The high density of seeding (50g/m2 ) coupled with the occurrence of humid and rainy weather seem to have contr ibuted greatly to the high 1ncidence of damping - off.porAcesso AbertoArtigo
