March 30, 2009 Recorded Pest Message in Print
Hi Fruit Growers,
Who wants to sign up for SkyBit? For $10 per month you can have daily
weather emails. You can get more information at http://www.skybit.com/cgi-bin/nav.cgi
The weather data from SkyBit is used in computer models to generate Orchard
Radar. This information is available to you without getting the daily
emails from SkyBit. Orchard Radar includes information such as when primary
apple scab season is over, when insect pests are likely to show up, when
trees need to be sprayed again for sooty blotch and flyspeck... There
is a whole lot of useful information - it's a great tool. This will be
available at the URI Apple IPM website: http://www.uri.edu/research/ipm/
Hopefully this will be ready by the end of this week.
2009 New England Tree Fruit Guides are in. There are a lot of chemical
changes from last year. The guide includes information on apples, pears,
peaches , plums and cherries. The cost is $30. Let me know if you want
me to send you a copy.
Another great tool is the newsletter from UMASS - Healthy Fruit. You
can sign up and pay for a subscription at http://www.umass.edu/fruitadvisor/fruitsubscriptions.htm
This costs $50 per year.
I plan on recording the first fruit pest message of 2009 on Thursday,
April 2. The number to call is 401-949-1456. I plan to report on whether
or not winter moths have begun hatching. My thoughts at this time are
that only orchards and blueberry farms close to the coast need to be
worried about spraying for winter moths. In the past few years we have
seen high numbers of winter moths in Bristol, Warwick, and Providence.
I am most concerned with farms in these areas and also Newport County.
Winter moth has not been a problem away from the coast - so far.
So if your orchard is in a winter moth danger zone, consider applying
an insecticide in early April. Winter moth caterpillars are pretty easy
to kill, if the pesticide is on the buds before the caterpillars enter
the buds. Imidan or most any insecticide should be effective. Last year
I found the first caterpillars April 8. I'll start looking again this
week and let you know what I find. You can email me or call if you have
See you soon!
