Efeitos da podridão negra no crescimento da couve ( Brassica oleracea var. Acephala)

Abstract

Black rot caused by Xanthomonas campestris pv. campestris, is an important cabbage disease. In order to contribute to the improvement of the growth on the disease, at the level of the peasants, the present study was made that constitutes a comparative analysis of the disease in two treatments (control treatment with the fungicide and without the fungicide) in the green areas of Maputo - Romão neighborhood. In the study area, at weekly intervals, 60 plants were evaluated in relation to the incidence and severity of the disease, as well as some growth parameters. There was no occurrence of the disease, which made it impossible to assess the incidence and severity of the disease, probably due to the time when the study was carried out, which was not favorable for its manifestation. The growth parameters did not show significant variations in the two treatments, except for the fresh weight of the stem and the root by the analyzes made in the statx statistical package version 2.0.
