As you know, we at City Fruit are passionate about pest management. We’ve blogged about it, sell City Fruit Shields to fruit tree owners, and are working to apply the footies on healthy trees in the city.
To help us with this, we’re working with Don Ricks to determine the status of apple maggot and coddling moth in the city, when to start applying pest prevention measures, and which to use.
We’re looking for volunteers to help him apply footies to fruit trees in two different orchard in the city:
Don is continually monitoring the situation in Seattle and has sent us this dispatch:
As of today (5/10/10) I am still not seeing codling moth in the trapsbut what I did see over the weekend is that some of the apples at the Good Shepherd Center are now big enough to apply footies to. Everywhere else, the apples are still too small or we haven’t even had complete petal fall yet.
One month ago it looked like we would have an exceptionally early season this year, but we have had some cooler than usual weather the past few weeks and this has changed the picture. Neither the bugs nor the fruit is developing as fast as we once thought, but we expect the weather ahead to be warming up shortly. Warmer climes, like the Rainier Valley, will need earlier attention. Cooler climes by the Puget Sound, or at higher elevations, might be a little later.
Consequently, the indications are now that the best time to apply foot sox will be the week before and after Memorial Day.
If you are spraying the organics Neem Oil, kaolin clay, or Spinosad products as your first cover spray for the codling moth, then probably mid- to late-May would be a good time to make the first application. This will have to be followed by sprays every 10 days or so until either harvest time or until you have covered them with foot sox.
The apple maggot fly will probably be flying in early- to mid-June, but stay tuned for further updates on when the fly is flying and (later in the season) when the fruit will be ripening.
