Seletividade de fungicidas cúpricos e sistêmicos sobre o fungo Cladosporium cladosporioides em cafeeiro

the occurrence of cladosporium cladosporioides on coffee fruits is frequently and coincides with the control of others diseases in coffee plants. the fungus cladosporium sp. has been found associated with coffee of good quality; therefore, it is important to use of selective fungicides to preserve it. on the study, six years old, coffee plants cv 'acaiá cerrado mg 1474' were selected and sprayed with cupric and systemic fungicides alone or associated copper oxichloride (50% of metallic copper). commercial 'calda vi？osa' was used as copper products and epoxiconazole as a systemic product. the incidence of cladosporium cladosporioides was evaluated four times using a scale. it was verified that on the treatments with the fungicide epoxiconazole applied isolate or in combination with copper fungicide the fungus was found at low levels but increased until may. on the treatments with copper fungicides the fungus incidence was high since may indicating that it was not affected or even was favored by previous applications of copper fungicides.
