Aspectos biológicos y control químico de la roya del clavel (Uromyces caryophyllinus (SHRANK) WINT) en la Sabana de Bogotá

In order to determine some of the biological aspects of the carnation rust and to evaluate some systemic and protectant fungicides, a research was done under laboratory and greenhouse conditions. The most efficient method of inoculation was the spray of uredospore suspension. Zineb, Oxicarboxin and Diclofluanid were the most efficient Inhibitors of uredospore germination. In the greenhouse trials, Oxicarboxin appeared to be the best fungicide followed by Triforine, Bitertanol, Diclofluanid, Zineb and Pyracarbolld. The fungicides Oxicarboxin and Triforine applied to the soli were much better th... Mehr ...
