Hummingbirds may reduce SWD

Research in raspberries at Cornell AgriTech over the last four years has shown promise as an alternative tactic to reduce the impact of SWD on berries. As described in a previous blog posted in 2014, Hummingbirds, these birds may indeed enjoy eating SWD. Preliminary data analysis for 2018 shows that when SWD numbers are very low […]

Use salt flotation to check for SWD

Effective use of salt flotation will help you determine if your fruit are infested with SWD and if your spray program is working. It also will give you a perspective on what your customers may find when they take the fruit home to eat fresh or to make pies, jellies, jams and preserves. I learned that variations […]

Organic Management Guide Released

A national team of researchers lead by the University of Georgia has released a new guide to organic management of SWD this May, 2018, Management Recommendations for SWD in Organic Berry Crops. The guide details information on non-chemical and insecticide approaches to protect berry crops against SWD. Controlling SWD is particularly challenging, requiring a rigorous, persistent and […]

Renovate Strawberry Plantings Promptly

Strawberry renovation is a critical, but often overlooked part of growing June bearing strawberries.  This year, with SWD numbers climbing, it’s even more important to remove fruit leftover in the field as quickly as possible. Otherwise, this fruit can serve as a food and reproductive resource for SWD population growth. The task that creates a […]

First Find in Rensselaer County

Two female SWD were caught in one of two traps set in an Amelanchier hedgerow immediately adjacent to a June bearing strawberry field during the week ending June 25, 2018. The two other traps at this location are inside exclusion netting over a blueberry planting and caught zero SWD. These traps are being monitored by […]

SWD insecticide quick guides updated for 2018

There were a few changes during the past year in the insecticides registered in New York State for SWD management. Most notably: Delegate WG, spinetoram (new product label, 62719-541) no longer needs a 2ee for use on stone fruits, grapes, brambles and blueberries. There is also a supplemental label for blueberries. Radiant, spinetoram (new product label, […]

More SWD being found – cherries at risk

In the last week of July 2017, my program found up to 100 SWD in some of the SWD traps in our raspberry research plot in Geneva, NY. Without a doubt, pressure from SWD and fruit infestation levels will be increasing as the SWD population explodes. In addition, fruit crops normally escaping infestation are reporting […]

Blueberry grower reports

Reports from blueberry growers have come in. SWD — caught in traps, found in fruit, and plantings shut down. One of these growers in the Southern Tier of NY, caught a single male in a trap on Sunday, July 23, 2017, and then, “In a matter of 3 days my 4 traps exploded with SWD. […]

Pruning caneberries to minimize SWD habitat within the planting

Examine your caneberry plantings for conditions that promote SWD infestation and take steps to eliminate them. Although we cannot change the weather, we can alter conditions in the planting to reduce the cool, dark, humid areas preferred by SWD. Pruning and training systems can help maintain an open canopy to increase sunlight and reduce humidity. […]

Protecting crops from SWD infestation

To protect crops from SWD infestation, once susceptible fruit is ripe and SWD is in your area, manage them aggressively. Using a combination of tactics is better than relying on one; and is the foundation of integrated pest management (IPM). Talk to your local Extension office about how to monitor for SWD, read Extension newsletters […]
