- Abstract
The effectiveness of Trichoderma harzianum in suppressing clubroot of brassicas, which is caused by Plasmodiophora brassicae, was tested on broccoli (Brassica oleracea var. italica Plenck), in field conditions, in Escagüey, municipality of Rangel, Merida State, Venezuela. The experiment showed that the applications of a biopesticide based on this antagonist had a significant effect on the percentage of health plants and the crop yields, in dependence of the dose used. In addition, the relation benefits/cost was also favorable. These results showed that, for these particular conditions, P. brassicae is an adequate biological alternative to control the clubroot of brassicas, no aggressive to environment and human beings, useful for the transition phase toward a sustainable agriculture, without chemical pesticides.
