Keep in mind that observations on blueberry and apothecia
development are taken from Berwick to Aylesford and may differ slightly to
individual farms.
With the exception of early Monday
morning this week has remained quite dry. Many growers decided to spray for
that wetting event because it took a very long time to dry off.
Looking ahead at the forecast, the
weather calls to remain dry with the possibility of isolated showers on Sunday
night/Monday morning. Despite the varieties being at a susceptible stage
and apothecia being active, if the weather remains dry the risk of infection
remains low. if rain is forecast the risk can quickly increase so growers
should continue to keep an eye on the weather forecast and be ready to
react.
Above early emerged apothecia are starting to age and dry slightly but are still active.
Below are later emerged apothecia.
