USO DE ÁGUA OZONIZADA E FUNGICIDAS CÚPRICOS NO CONTROLE DE CERCOSPORIOSE EM MUDAS CAFEEIRAS

Abstract

This study aims to verify the comparative effect of ozonized water and cupric fungicides in the preventive control of Cercosporiosis and vegetative characteristics in coffee seedlings. Thus, the research took place in a shaded environment. treatments, consisting of: T1 witness; T2 with ozonized water; T3 with application of fungicide Copper hydroxide; T4 with copper hydroxide + ozonized water; T5 with application of copper oxychloride; T6 with copper oxychloride + ozonated water. So the The climate was not conducive to the occurrence of cercosporiosis (Cercospora coffeicola). According the diagrammatic scale showed a low incidence of the disease, in the work of JULLIATI (1997), that the increase in the incidence of the disease in the period from May to late July, it is possibly due to the low temperatures that usually occur during this period, associated with loss or reduction of nitrogen level in the leaves.
