Abstract

The effect of Nitrogen fertilization on the infestation level of D. saccharalis in flooded rice was observed in two different field experiments. In one of them, plants that received basal and split application of Nitrogen (total of 100 kg N/ha) were more infested by stem borer than plants that received only basal application (50 kg N/ha). In the other experiment, under various Nitrogen fertilization levels (30, 60, 90, 120, 150 and 180 kg/ha). Nitrogen rates and stem borer infestation were highly correlated (R = 0,975**).
