2016 monitoring network in NY

jec3@cornell.eduJune 15, 2016Leave a comment

The SWD monitoring network for 2016 is set up. Twenty-five people are collaborating on the network this year, including Cornell Cooperative Extension agriculture educators, regional fruit educators, and extension faculty. A total of 117 Scentry traps and lures are deployed in the network, primarily in raspberry (summer and fall) and blueberry, in 25 Counties.

Most sites are reporting no SWD finds to date, but a few reports have come in of SWD caught in traps. Related to that, this week's trap monitoring at Dr. Greg Loeb's research site caught no SWD (see blog, Ontario County first find), which may indicate that populations are still sporadic and low.

2016 SWD Monitoring Network: collaborators, Counties, number of traps and crops.

Ontario County first find

jec3@cornell.eduJune 13, 2016Leave a comment

Dr. Greg Loeb’s entomology research program, Cornell University, Geneva, NY, has caught 3 SWD females in traps set on the edge of a blueberry planting that is adjacent to woods in Ontario County. This blueberry planting is often the site where Greg’s program catches SWD first. Traps were set out on May 31^st and checked on June 7^th, which indicates the SWD were caught sometime during that week. The good news is that the blueberry crop is not ripe and therefore not vulnerable to oviposition at this site.

This is the earliest that SWD has been caught in New York State since monitoring began in 2012. The mild winter that occurred in New York, with only one significant cold snap around February 14^th, may have contributed to early arrival and overwintering success of SWD. Mild winters and early SWD arrival is the typical situation that is now found in Europe with this invasive insect.

Research by Dr. Anna Wallingford, a post-doctoral associate in Greg’s lab, and others is finding that SWD goes into reproductive diapause in the late fall during which time egg laying ceases and overwintering survivability increases. The traps used to catch these three females were baited with a fermenting lure that is being researched by a team at Rutgers the State University of New Jersey. This same team has research that is underway, on the female SWD caught in these fermenting lure traps, to determine if these early-arrival females are ready to lay eggs.

There is no doubt, the SWD season has begun in New York and it looks as if the 'mild winter early arrival' predictions may prove true. Please note: this finding won't show up on the SWD distribution map, because research trap sites aren't part of the 'map-reporting' monitoring network.

Exclusion netting against SWD

jec3@cornell.eduApril 19, 2016Leave a comment

Get your order in NOW for exclusion netting to cover your berry planting and protect it from SWD infestation. Contact Dale Ila Riggs, The Berry Patch, Stephentown, NY at berryprotection@fairpoint.net.

If you have an existing framework to protect your blueberries from birds, the exclusion netting can be placed on that framework. Read the full report on exclusion netting research, funded by NE SARE, The use of insect netting on existing bird netting support systems to exclude spotted-wing Drosophila from a mature small-scale commercial highbush blueberry planting. (url is http://mysare.sare.org/sare_project/fne14-813/?page=final)

Dale Ila Riggs writes in her report:

"The system worked extremely well. In 2014, with the 80 gram netting, at most, only 0.53 percent infestation occurred in a 10 week harvest season. Unsprayed berries without exclusion netting had as high as a 60% infestation level in one sampling period alone. In 2015, using the 80 gram netting, at most, a 0.37% infestation was found over a 5 week harvest season. Sprayed berries without exclusion netting had as high as a 20% infestation level in an individual sampling period. The netting held up through 3 severe thunderstorms and 2 hail storms and we refined our attachment system for large scale deployment of large pieces of netting.

This system has great potential for small scale, organic, and no-spray blueberry growers and I believe the system can be used by raspberry growers as well."

Beautiful, ripe raspberries without SWD, that's the goal of every berry grower these days! Including Dale Ila Riggs, The Berry Patch, Stephentown, NY.

You can order the exclusion netting from Dale Ila Riggs, The Berry Patch, Stephentown, NY. For questions, contact her at berryprotection@fairpoint.net. Orders with Tek-Knit must be finalized this week.

If you've been considering protecting your berries from SWD with exclusion netting, read the report to see if this approach could work on your farm. Don't delay, contact Dale Ila to get the netting you need as part of her bulk order with Tek-Knit.

SWD Stakeholder Survey

jec3@cornell.eduMarch 31, 2016Leave a comment

The Sustainable Spotted Wing Drosophila (SWD) Management for US Fruit Crops project, funded by NIFA, needs your help. This five-year project is developing national research and extension approaches to minimize the impacts of SWD. They include:

new management tactics and programs
expanded pesticide registrations for SWD
information and training on SWD for growers, extension agents, and others

In order to achieve this and ensure that the research and extension efforts match the needs of growers, the project is collecting information on the impacts of SWD on berry and small fruit growers' farms, your current management practices and preferences, and your needs for better management of SWD.

Participation in the survey is voluntary. The survey doesn't collect personally identifying information and the data will only be analyzed and reported in aggregate form. Please help us help you by providing your perspectives on SWD in the survey.

Entrust organic insecticide – don’t overuse!

jec3@cornell.eduAugust 12, 2015Leave a comment

An important warning from Dow AgroSciences, the manufacturer and distributor of the organic-approved insecticide, Entrust SC, about the use patterns of this product for control of SWD - don't overuse it, follow label directions and rotate with a different active ingredient. (Excerpts from their letter are in quotes. I've added bold emphasis.)

It is crucially important to follow the "labeled resistance management restrictions for Entrust SC in organic cropping systems in the Northeastern United States targeting Spotted Wing Drosophila." It is my understanding that, in New York, Entrust is under a 2ee registration and you must have the 2ee in your possession when applying this insecticide; ask your supplier.

"Entrust SC Insecticide is a solution for control of economically important arthropods across many different crops. This product is registered for organic use and is OMRI certified. The active ingredient Spinosad is a group 5 insecticide, which offers a unique mode of action. Dow AgroSciences is proud to offer a unique class of chemistry for organic growers."

Insecticide rotation to different IRAC groups

"At Dow AgroSciences we take (insecticide) resistance very seriously and investigate all situations we are aware of in which non-compliance may be occurring or where performance is in question. We strive to make sure our products are stewarded correctly in the market to follow label language with regards to use patterns. Specifically, our labels include Resistance Management directions which state that rotation to other insecticide classes should occur after two consecutive applications." For many fruit crops, only three total applications of Entrust may be applied per season—read and follow label directions.

Organic insecticide rotation guidelines -
For organic management of SWD, rotate to a different insecticide active ingredient after applying one, no more than two or three (depending on the crop label) Entrust (group 5 insecticide) sprays. Options for rotation partners include the active ingredients azadirachtin (group UN insecticide) and pyganic (group 3A insecticide). While spinosad (Entrust) has good to excellent activity against SWD, azadirachtin and pyrethrin have fair to poor activity against SWD. Save Entrust applications for when SWD populations are high and fruit is at high risk.

Azadirachtin is the active ingredient derived from neem oil. Trade names include, but are not limited to, AzaSol, Aza-Direct, AzaGuard, AzaMax, and Azatrol EC. These insecticides may not be labeled on all fruit crops, so read the label carefully before purchasing and using this insecticide. Group UN - mode of action is unknown or uncertain.

Pyrethrins are active ingredients derived from the plant Chrysanthemum cinerariifolium. Pyrethrin insecticides are highly toxic to bees, so don't use these when pollinators are active. Trade names include, PyGanic EC 1.4 and PyGanic EC 5.0. These insecticides may not be labeled on all fruit crops, so read the label carefully before purchasing and using this insecticide.

Insecticide application frequency and amounts per season

Dow AgroSciences has also "been made aware that Entrust SC is allegedly being used at a greater frequency than the label allows per crop. Dow AgroSciences is closely monitoring this situation to understand if these are isolated cases or more widespread occurrences." Entrust is typically limited to 3-5 applications per season, depending on the fruit crop, and always no more than a cumulative total of 9 oz per acre per season.

When an insecticide is applied too often and at higher cumulative rates than research on the chemistry warrants, a sensitivity shift in the target insects can occur over the course of a growing season. Over several growing seasons, SWD individuals with reduced Entrust SC (Spinosad) sensitivity could make up the majority of the SWD population in organic cropping systems. We are very concerned about this and work is ongoing to identify more effective insecticides for rotation partners in organic systems.

If resistance to Entrust SC (Spinosad) is selected in organic systems due to overuse and lack of rotation, IPM growers using the group 5 insecticide Delegate WG (Spinetoram) could lose this insecticide due to group 5 insecticide sensitivity shifts in the SWD population. Spinetoram is the chemically synthesized spinosad active ingredient and it, currently, has excellent activity against SWD—it, too, should not be overused. Likewise, if IPM growers overuse Delegate, this could have negative repercussions on the activity of Entrust.

Let's keep Entrust in the Northeast!

"...if non-compliance continues then Dow AgroSciences will pursue corrective action which could include withdrawal of Entrust SC from the Northeastern United States. If you have any questions, please contact your local Dow AgroSciences partner."

Take the time to learn about resistance management and follow the label directions that are designed to help prevent this from occurring.
