- Abstract
The maize white spot stands out as an important disease for all regions where corn is cultivated. This disease is related to significant damage to corn crop by to reduce the productivity, especially when none treatment is apply. Although there are still controversies about the etiology of the disease, the latest evidence relates the bacterium Pantoea ananatis as etiological agent. The chemical control is the most effective tactic employed to avoid the disease progress. According to this doubt our objective was to evaluate the maize white spot severity by the application of antibiotics in two stages (V8 and pre-tasseling) to obtain the best strategy for the chemical control of this disease. The experimental design was randomized block design (RBD) with six treatments and four replications and two positive controls. The treatments were: oxytetracycline + streptomycin (400, 500 and 600g cp/ha), oxytetracycline (300, 400 and 500g cp/ha), epoxiconazole + pyraclostrobin (750ml cp/ha) and mancozeb (2500 g pc/ha). Significant difference was noted for all pesticides applied at V8 and pre-tasseling stage. The antibiotics controlled the disease as good as the fungicides, resulting in rising the productivity.
