Use of antibiotics and yeasts for controlling Chinese cabbage soft rotThe soft rot caused by Pectobacterium carotovorum subsp. carotovorum (Pcc) may occur in Chinese cabbage (Brassica pekinensis) plantations presenting till 67% of incidence. In this research we evaluated the Pcc sensibility to bactericides in vitro, the effect of Mycoshield ® at 3.0 and 1.5 g L -1 , and yeasts at 10 8 cel/mL -1 to control the disease in greenhouse and field. Plants were sprayed with Mycoshield ® (oxitetracycline 20%) and yeasts (Rh1 and Rh2 (Rhodotorula spp.) and Sc1 (Saccharomyces cerevisae)) seven days after transplant and inoculated with the isolate Pcc120 seven days and 12 h after treatment, respectively. In all experiments disease epidemiological components were evaluated. In vitro 40 Pcc isolates were resistant to copper sulfate and sensitive to oxitetracycline, streptomycin, oxitetracycline + streptomycin and oxitetracycline + copper sulfate all at 0.2 g L -1 . Six Pcc isolates were more inhibited by Mycoshield  than by Agri-Micina ® (oxitetracycline 1.5% + streptomycin 15%) both at 3.0 g L -1
