Rainfall on early Monday morning
represents a significant infection risk and growers should apply a group 3
fungicide using its "back-action" to prevent infection.
If growers had sprayed in the last five days they should still be
protected for this rain event.
Growers are urged to pay attention to the weather forecast this week as the blueberry varieties move through the critical infection stage of development and apothecia are present and actively releasing spores.
