Stop the spread of Botrytis with NoPath

Botrytis is everywhere and could strike at any moment. While sudden outbreaks usually don’t happen, an unexpectedly rapid advance could. As a grower, you have various ‘tools’ to stop the fungus.

Humidity is key to Botrytis’s ability to strike. The spores of Botrytis germinate easily and quickly in wet conditions and at high humidity. If the foliage is wet for longer than six hours, the chances of germination and therefore the risk of infection is very high.
A temperature of 15 to 20 degrees Celsius is most ideal for Botrytis spores to germinate. That doesn’t mean they won’t germinate at lower or higher temperatures – only more slowly. Little wind or air movement and dark weather promote the germination process. A dense crop and full foliage are also ideal conditions for Botrytis spores to germinate.
Easy entry points for infection are wounds on fruit, e.g. as a result of damage by wind.

Create the right conditions

How do you stop Botrytis spreading and nip it in the bud?

Preventing a humid climate is crucial here. If you have greenhouse crops, you can effectively stay in control and create the desired ‘drying’ effect. To do so, it’s important to ensure the crop dries quickly after irrigation or spraying by opening the windows or switching on the fans. This ensures sufficient air flow and prevents the humidity from rising too much.

The situation is a little more complex in outdoor crops, as you have no control over the weather. Only by means of cultivation management can you get some control of the situation. Implement crop measures that create enough air movement in the crops – ensure generous planting distances between plants and remove leaves. This will help the crop to dry faster after wet weather, such as a rainstorm.
It’s also important to ensure your crop is strong and vigorous: crops like these are better able to withstand a Botrytis infection than weaker crops.

Biological control

If you notice an infection, you should apply NoPath. NoPath is a natural plant based on plant essential oils for use in a wide range of crops including ornamental crops and vegetables.

How it works

Mode of action

The essential oils disturb several essential biochemical processes in cells of harmful disease-causing fungi. This disturbance leads to the death of these cells.

Visual effect

Progress of disease stops or slows down.
