Resumo
The increment of tne growth of tree conservat,on by means of official incentive, greatly intensitied the planting' of eucalyptus in Brazil, creating the necessity of producing seedlings 1n great uantities. 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.
