I posted this website last year
By registering on this site, people (especially in Washington) can try to get a fix as to when various pests/diseases/etc. are plaguing fruit growers and what might be done as a preventative.
People in the Portland area could try to get the WSU Vancouver site and log on there in order to get an approximation as to what to expect for neighboring Portland.
I confess it is a little time consuming to get to know this website, but this website does indeed seem to offer valuable info for Eastern Washington growers.
I am not at all sure that the website is applicable for western washington or Western Oregon people, though, as our wetness adds a variability that is not factored in to the modelling data.
Last year this website accurately predicted codling moth for Seattle, but it did NOT accurately predict the apple maggot fly arrival times when I used the "21 acres" site as our model.
This year, this website would indicate that the codling moth will be flying in the vancouver area about May 22nd and in the Seattle area about May 27th. Wow.... That seems kind of hard to believe because I know the fruit has been incredibly delayed this year.....shucks, the apple trees are just now in bloom and just now (this week) going to get some good pollination weather.....don't tell me the codling moth is coming out soon, because there is no way the apples will be big enough for me to use foot sox on them early enough to protect them all.....(although I am sure they will still help). Is it possible our excessive rain will also delay the codling moth? I hope so.
Anyway, I will let you know if codling moth traps actually capture any codling moths in the Seattle area this month.....(the only sure indicator)......and hope others from Portland will post as well if they detect the codling moth.
The apple maggot fly is still a long, long ways away.
Greenthumb,
Today, I talked via email to Ute Chambers in Wenatchee who is running this website and she gave me several bits of info which I hope to relate.......but for the time being let me just post what she sent me as to how to log in.
" HOW TO REGISTER AS A NEW USER AND LOGIN INTO DAS (WEBSITE)"
1. "To login to DAS use the sign-in box in the upper right corner of the DAS welcome page."
2. "If you are a new user you need to set up an account with DAS. Click on “Sign Up†to open the registration window. Here you enter your name, your email address, your business or orchard name, and your zip code. Then you type in the username you want and enter and re-enter the password you want."
3. "Click on this link to read the disclaimer. When you have read the disclaimer you can close the window and check this box."
4. When all entered information is correct you can press register. You will be sent an email from WSU to confirm your registration. Make sure that the confirmation email did not end up in the email junk folder.
5. In the DAS New Registration Confirmation email sent to you click on the link “Activate my accountâ€, and you will be directed to the DAS account confirmation page. If this activation link does not work you can copy the text link below it and paste it in your browser. When you click on “Activate my account†the browser will open the DAS account confirmation page. Click here to confirm you account activation.
6. Now you can login to your DAS account with your username and password. You will be directed to your profile page where you can set up your stations.
7. When you are done checking your stations and models you log out of DAS by simply closing your browser. If you have checked the “remember me†box, the browser will then recognize you when you login again. You can also logout by clicking on “Sign outâ€. This will bring you back to the DAS welcome page. In this case you will have to type your username and password to login again.
8. "If you forget your password just click on “Email Passwordâ€, then enter your email address in this new window, and your password will be sent to you via email within a few moments."
Greenthumb, I will have more to say about what to do after you have logged in later.....
By the way, I helped edit and create this little website link today about putting on foot sox, for anyone interested.
http://pipersorchard.org/categ.....-foot-sox/
A few more thoughts:
1. Ute says "there is also a video on the front page that shows how to sign up (under "video help" in the upper right area in the grey bar above the sign in box)."
2. Also, "you can tell people that there is a link "Contact us" on the bottom of the DAS home page, and people can send any questions through that little pop-up window" if you have questions for her. Her name is Ute Chambers and she is bright and quite helpful. Also, she says " DAS does not work on the new Windows Internet Explorer 9. It will take time to fix that and we recommend users to use other free browsers (Google Chrome, Firefox, or Safari)."
3. Also, to my comment on why models may not be accurate on the west side... Ute says " Not only is rainfall an issue (especially apple maggot), but also the milder winters on the west side can affect emergence of pests and how synchronous that emergence is."
I have my website set up for two stations, the "WSU Vancouver RE" station and the "21 acres station." I have apple maggot, cherry fruit fly, fireblight, scab, and codling moth as the areas of interest under my "21 acres station." Then, after I log in, I click "view models" at the top and then "by station" in the pop-up box below that.....and then click "21 acres" on the left side of my screen. If all is done properly then the info shows up for me.
Here is what the info that shows up says for codling moth for the Vancouver station for today, May 20th:
Codling Moth
Last Updated: 05/19/2011
Degree days since January 1st. = 166
Current Conditions:
CM emergence is expected in 1 days (=175 DD). Historically first moth is caught between 121 and 220 DD (average 175 DD). Studies show the 175 DD figure used as a biofix does not affect model accuracy compared to using a biofix.
Management:
Pheromone traps should be in place before first apple blossoms open or by 100 DD whichever comes first. If using mating disruption, dispensers should be in the orchard before the first apple blossoms open and use a 10x lure for pheromone traps.
Projected Forecast:
Conditions:
5% of CM adults should have emerged. No eggs have hatched, but they should start being laid 225 DD (50 DD after biofix).
Management:
If you are going to use an insecticide that kills CM eggs (Intrepid, Esteem, Rimon), it should be applied between 225-325 DD (50-150 DD after biofix). Using an ovicide at this time allows you to delay the first larvicide application to 525 DD (350 DD after biofix). If you are planning to use an insecticide at an egg hatch timing then a repeat application of the ovicide is not necessary. If an ovicide only control program is followed (not recommended) then two additional applications at a re-treatment interval of 14 days should be used.
--------------------------------------------------------------------
Editor's Note: In other words, at the risk of totally killing the science here and being inaccurate, I (Don Ricks) would say this: the codling moth is starting to come out in the Portland area.....we still have many more scientifically calculated "degree days"...... DD, (or, translation, without explaining what degree days mean:) we have a handful of regular days before there is any sort of significant number of eggs out there....and then more days after that before they hatch into our troublesome little larvae that eat into the apple......but it is time to start being watchful.....the codling moths are slowly starting to emerge and then to mate, and then in the near future to lay eggs and then in the future after that, the eggs will hatch......forgive me for over-simplifying it all.
am 90 % certain (without taking to an entomologist) that it was a codling moth that I saw on a trap that I placed here in Seattle at an area that gets early infestations. This is at an area that I know has a particularly warm micro-climate. I spotted this yesterday, May 23rd.
Micro-climate is everything......there are some areas in the Puget Sound area that won't get codling moth in any numbers to speak of for another month.....believe it or not. I suspect elevation, wooded areas, natural predators, amount of pavement nearby, and nearness to the water are all influencing factors, as well perhaps, as the number of "host" sites, such as apple trees (and maybe Hawthorns) that are nearby.....all of these are factors that determine the onset and "pressure" of the codling moth barrage.
It is my belief that if I saw a codling moth here in Seattle, then the slightly warmer (this year) Portland area probably has some flying around as well now in some parts.
