  • The black sooty mould can be sticky and is the result of a whitefly attack.
  • Cabbage whitefly overwinters on brussel sprouts as adult insects.
  • Adult whitefly and their nymphs suck sap from the sprout plant and excrete a sugary substance (honeydew) onto the leaves.
  • Sooty moulds then grow on this sugary substance – and can make a real mess of the sprout buttons.
  • The warmer the weather the worse the problem is.
