UCONN IPM: Integrated Pest Management:Tree Fruit:Apples:Weekly Pest Message

Fruit Pest Message
March 26, 2009

Hello Connecticut Fruit Growers,
This is my first Fruit Pest Message of the 2009 season. As usual, I will send pest alerts, meeting notifications, etc. throughout the season.

New England Tree Fruit Management Guide
The 2009 New England Tree Fruit Management Guide has just arrived from the printers! The Guide includes extremely useful information, particularly with regard to pesticides & pest management. A number of new products were added this year. The Guide covers all tree fruit crops grown in New England including apples, pears and stone fruit. They are now available from the UConn Communications and Information Technology Office; Unit 4035; 1376 Storrs Rd.; Storrs, CT 06269 or (860)486-3336. The cost of $35 includes Shipping & Handling. Credit cards are accepted. Order soon so you can be prepared for the upcoming season!

Apple Scab
Dan Cooley, Arthur Tuttle and Jon Clements from the University of Massachusetts just published a new factsheet “Reducing Apple Scab Risks and Saving Scab Sprays”. Of particular interest is a discussion on reducing scab inoculum using a urea spray on the orchard floor now. You can see it by clicking on: http://www.umass.edu/fruitadvisor/factsheets/f134.html

There is more on the subject of reducing scab inoculum in an article by Dave Rosenberger in the NY Scaffolds Newsletter. See “Act Now to Reduce Scan Inoculum in Problem Orchards” in the March 23, 2009 issue. http://www.nysaes.cornell.edu/ent/scafolds/2009/090323.pdf

Dave Rosenberger has an article in that same issue that you might also find interesting, “Expect Fungicide Supply Complications for 2009”.

Insect Traps and Pheromones
I try to put the first set of insect traps up at apple silver tip. These are white sticky traps for tarnished plant bugs in apples and red sticky traps for apple blotch leafminers. Both of these traps (as well as a number of other insect monitoring supplies) are available from Great Lakes IPM; 10220 Church Rd. NE; Vestaburg, MI 48891. (800)235-0285 or www.greatlakesipm.com

Weather Stations
Once again, I’m planning to have weather stations in a number of orchards in 2009. I will give you E-Mail updates on apple scab, fire blight and summer disease predictions based on the weather data. I’m hoping to have at least a few operating by April 1.
