Be proactive with Botrytis control


When considering your approach to managing Botrytis this autumn, proactivity will be key in controlling the fungus and making sure crops stay healthy through the dull winter months.

It’s important to stay vigilant during periods of high humidity and low light levels, as this is when the fungus is most prolific.

An integrated approach

Botrytis is best managed using an integrated approach, which incorporates cultural controls, regular monitoring, biologicals and conventional chemistry.

Alternating products that have different Modes of Action (MoA), and timing the applications according to weather conditions and disease pressure in crops, is key.

For example, Frupica SC, has very strong preventative activity and so, tank mixing this botryticide with a multi-site MoA partner such as Karma, where the label permits, will also help to form a robust anti-resistance strategy.

Top tips for Botrytis control:

  • Ensure that crops are well ventilated – open doors and vents to allow airflow, even if only for a couple of hours
  • Ensure crops have the right amount of nutrition for the plants to store sugars in the crowns
  • Monitor the crops, remove and dispose of any affected parts of the plants
  • Maintain a strict hygiene protocol when planting new crops
  • Utilise specialist light penetrating polythene films for tunnel covers which will help reduce sporulation
