Monitor your orchards at least fortnightly for
levels of pests and diseases and assess the potential risk of infection or infestation.
Use the schedule in the Defra Best Practice Guides for Apple and Pear Production.
Take into account predictions from pest or disease models and weather forecasts.
If spraying is justified, choose an approved pesticide
which is as safe as possible to humans, wildlife and the environment, but which at the
dose recommended on the label will give effective control of the target
pest or disease in trees of the standard height and density at that
growth stage.
Check the product label for the dose recommendation.
Finally, select the pesticide type that best fits the description in the
menu options and tick the box to indicate that you have done all the above.
