Possibilities of biological and chemical control of Verticillium wilt in pepper
Phytoparasitica 35 (5), 436-441
Abstract: In pathogen populations in Serbia, the incidence, pathogenic and morphological characters of Verticillium spp. were studied. Biological and chemical control of Verticillium was investigated in pepper plants (Capsicum annuum L. cv. 'Soroksari') with the biofungicide Polyversum (Pythium oligandrum) and the conventional fungicides benomyl and propamocarb-hydrochloride. On the basis of macroscopic and microscopic characters of the isolates originating from eight localities in Serbia, it was established that they apparently belong to the species Verticillium dahliae. The isolates differed in their pathogenic characters. However, all of them caused marked wilting symptoms on pepper plants 40 days after inoculation, conducted when there were more than nine fully developed leaves on the primary stem. The fungicides were applied either before or after inoculation. Benomyl was the most efficient fungicide in wilt control (88.2% when applied after inoculation and 94.6% when applied before inoculation). Polyversum proved more efficient (66.6%) when applied before rather than after inoculation. Propamocarb-hydrochloride provided sufficient Verticillium wilt control; its efficacy and that of Polyversum were similar, and less efficient than benomyl, but still significantly different from the disease control.
