Biological Activity: Carbendazim mixture with flusilazole is a fungicide used to control sooty mold caused by Botrytis narcissicola. The disease is the most common foliar disease of daffodils (Narcissus cultivars) in the UK and causes significant losses in bulb and flower production. Carbendazim mixture with flusilazole was found to be effective in reducing lesion size and significantly reducing symptoms of secondary sooty mold after spraying when used in combination with several other fungicides. In field trials in Cambridgeshire and Lincolnshire, a spraying program using this fungicide mixture was effective in controlling sooty mold. In addition, alternating four to six sprays using two or three fungicides with different modes of action not only reduced disease damage but also increased bulb production. The study discusses the selection of appropriate fungicides and control methods that may reduce the number of spraying applications.
