Efficacy of PostivaTM for Management of Bacterial Diseases of Ornamental Crops

Pathogen management commonly includes environmental regulation and sanitization. There are limited numbers of effective registered bactericides. In 3 years greenhouse trials, PostivaTM, a premix pydiflumetofen (6.9%) difenoconazole (11.5%), was tested for activity against xanthomonas leafspot geranium, zinnia, ficus bacterial wilt geranium caused by Ralstonia solanacearum. PostivaTM applied at 0.73–1.5 L/ha significantly reduced disease incidence and/or severity on each crop tested. applications were similar (p = 0.05) to commercially available standards zinnia ficus. (0.73 L/ha) that observed with Cease® (9.35 L/ha). may be beneficial in an integrated program control diseases. is highly promising as rotation option reduce the buildup populations resistant copper compounds antibiotics frequently used industry.
