A pest-resistant variety of strawberry has been produced by genetic engineering.
Researchers grew the GM strawberries and non-GM strawberries in matched fields on five farms for three years. The table shows the mean results per growing season.
| Type of strawberry | Yield in tonnes per hectare | Number of pesticide applications | Number of insect species recorded at the field edge |
|---|---|---|---|
| GM | 24 | 2 | 11 |
| Non-GM | 18 | 5 | 16 |
