摘要

The fungicides belonging to the chemical groups of strobilurins and triazoles have their contribution to increase the productivity of the crop by a phytotoxic effect. The objective of this study was to evaluate the effects of fungicides at different times on the quality and quality of the spikes. The experiment was conducted at the Universidade do Estado de Minas Gerais and the experimental design was in randomized blocks, with 4 replicates, factorial factorial 3 × 3 + 1, the first factor being composed of 3 combinations of fungicides and the 2 applications (49, 56 and 63 days after sowing-DAS) + 1 witness. The lot was composed of 4 rows spaced 0.45 m and the harvest was done manually at 83 DAS. The height of the plant, the height and the diameter of the glue in the first ear, total mass of ears with and without straw, grain mass per ear, length and diameter of the ears and productivity were evaluated. The data were analyzed by variance and as means compared by the Tukey test. The height of a plant was significantly affected throughout its life in the treatments at 63 days. The series were concentrated by the treatments are a non-spike mass, grain mass per spike and productivity, and pressure levels were loaded when they were performed at 63 DAS.
