In a popular boek [Klazien uit Zalk, a Dutch writer 1991] I found that Borage [Borago] could protect strawberries against all king of insects.

Good to know for growers of strawberries which really should not be eaten if treated with pesticides.

With ChatGPT I found the following:

Yes, borage (Borago officinalis) can help protect strawberries against certain insects. Borage is a flowering herb that is known to have pest-repellent properties. It contains compounds, such as pyrrolizidine alkaloids, that act as natural insecticides.

When grown near strawberries, borage can attract beneficial insects like bees and wasps that help pollinate the strawberries and prey on pests. These beneficial insects can help control populations of aphids, thrips, and other insects that may damage the strawberry plants.

Additionally, borage has been reported to repel certain insect pests due to its strong fragrance. Some insects, like Japanese beetles and tomato hornworms, are known to be deterred by the scent of borage. However, it’s worth noting that borage may not provide complete protection against all types of insects, and its effectiveness can vary depending on the specific pest pressures in your area.
