O controle da ferrugem do cafeeiro baseia-se principalmente na utililllção de fungicidas e vem apresentando resultados satisfatórios. Entretanto, devido aos possíveis problemas, como o desequilíbrio biológico (9), acúmulo de produtos no solo e nas águas, seleção de linhagens resistentes do patógeno entre outros, há necessidade de estudar alternativas a esse método. Em relação ao controle biológico, Vertieillium kcanii (8, 13) e Bacillus subtilis (4, 11) vêm apresentando resultados promissores no controle da doença. Baeillus subtilis (Ehrenberg) COM e seus metabólitos vêm sendo estudados com alternativas ao controle químico de fungos fitopatogênicos com relativo sucesso (1, 2, 3, 4, 5, 12, 14, 15, 17). Essa bactéria apresenta grande capacidade em inibir os fitopat6genos causadores de ferrugens tais como: Uromyces phaseoli (1, 2, 5, 6, 14); Puceinia pelargonii-zonalis (19) e Hemikia vasta/ri.>: (4, 11). Além de B. subtilis, outras espécies de Bacillus têm ação sobre ferrugens como: B. cereus em Puccinia alUi (7); B. pumilus em Puccillia recolldita, Puceinia graminis f. sp. tritiei e Puceinia coronata (15). Considerando esses aspectos, o presente trabalho teve por 01>jetivos avaliar o efeito de produtos obtidos de B. subtilis sobre a ferrugem do cafeeiro (Hemileia vastatrix Berk.) e o potencial '994 Grupo Paulista de Fitopatologia. showed a reducrion on (1) lhe perUnlage of infecled Je(llles; (2) rwmber of Jeslons per leaf anil (3) rwmber of lesion.s per infecred leal. 1he alrocl GPU(13)12 h(llle no syslemic acrion in lhe ascendam, ckscendanl and lateral direcrion.s. 1he direcl appJicarion of fermeruarive material of lhe foliar femlizer tkrived from lhe gluJamic fermentarion of molasses (concenrrarions of 10,25, 50 and 100%) showed an eJJeclive control ofcoJJu leaf rnst when considend lhe above parameters. sistêmico dos metabólitos de B. subtilis em cafeeiro.
