Speaking at British Protected Ornamentals Association technical seminar Life Without Pesticides, she said it was important for all nursery staff to understand the basic principles behind pest and disease control.
"It's very important that all members of staff in the nursery understand the basics," she added. "But the most important thing is the inspection of the plants.
"Everybody should be doing it all the time, but one person in particular should have a responsibility for it and you should check all the plants as they come in."
She advised growers to:
- Maintain nursery hygiene to help prevent the spread of diseases.
- Take care to control the glasshouse environment.
- Regularly inspect crops for pests and diseases.
- Act swiftly to control disease once it has been identified.
- Have a plan of what you are going to do and make sure you keep records of what you have done in the past for reference.
