EPA Product Cancellation Order for Certain Pesticide Registrations

As per registrant request, the EPA has canceled the registrations of twelve neonicotinoids, mostly various granular formulations of Thiamethoxam and Clothianidin. The cancellation was effective May 20th, so it’s possible these are on your shelves. I tried to search for them on NYSPAD, and none were in the system of pesticides registered in New York. I’m not sure if they were never registered in New York, or if the DEC was just that quick to remove them from the NYSPAD system. Please check your shelves for the products listed in Table 1 (EPA, 20 May 2019, Product Cancellation Order for Certain Pesticide Registrations)., and read Section VI. Provisions for Disposition of Existing Stocks.

“Telling Your Story”, a discussion group meeting for farm women.


“Telling Your Story”, a meeting for farm women, will be held on Tuesday, June 4, 2019 at Cornell Cooperative Extension, 24 Martin Rd, Voorheesville, NY 12186.

The Capital Area Agriculture and Horticulture Program and Cornell Cooperative Extension Albany County will host the meeting, which runs from 6:00 to 8:30 pm and is intended for farm women who wish to learn the key skill of telling their farm business story as a way of engaging customers and the public.

Inspired by Annie’s Project, a working group of farm women selected this topic as a key skill they wanted to learn. We invite other farm women to join us as we continue our women’s discussion group, which meets to provide support, programming and networking opportunities.

Making a personal connection is a crucial element for businesses to use when competing in the rough and tumble world. Steve Hadcock, CCE educator for New Farmers and Market Development, will work with the discussion group participants to develop messages for their use on social media and in their marketing campaigns.

As messages about food, local agriculture and other concerns continue to be diluted by misinformation, farm business owners must step up their game to produce materials and stories that engage and educate customers and the general public. Finding key points to convey the message you want everyone to understand is part of that process.  

The meeting is free and reservations are not required. However, a call/text or email ahead to Sandy would be helpful in planning for handouts and space. Call 518-380-1498 or 1-800-548-0881 or email sab22@cornell.edu.

Scouting Updates: Aphid Management in Greenhouses

by CAAHP Ornamental Horticulture Educator, Lindsey Christianson

Many of you have already seen and possibly already treated for aphids in your greenhouses, but with the cool weather keeping everything closed up, interiors are perfect for aphid populations to rebuild. If you use biological control agents for aphid management, you’ll want to release them as soon as possible.

How do you decide which beneficial bug to release?

 First things first: Are you finding green peach, melon, or foxglove aphids? Cornell University’s Dr. John Sanderson put together a quick guide (pdf) to help identify these three aphids that will probably be the most likely to show up in your greenhouses.

I found these foxglove aphids on fuschia in a greenhouse on May 1. This species can be distinguished from green peach aphids and melon aphids by 1) the antennae that are longer than their body, and 2) the dark green patches on their posterior, around the cornicles.

Melon aphids are generally the smallest of the three, and range in color from a very light yellow to a dark green/almost black. The easiest way to distinguish these from foxglove and green peach aphids is that the entire length of their cornicles are black.

Green peach aphids exhibit a range of colors also, but have shorter antennae that don’t extend the full length of their body.

The predatory midge Aphidoletes aphidimyza is a great way to get started in aphid management without necessarily having to know which kind of aphid you have. The larvae aren’t picky about which aphids they’re eating, and they’re voracious feeders.

Native lady beetles, Adalia spp. and  Hippodamia spp., are also recommended. However, as generalist predators that are fairly large, they’ll eat just about anything, including each other and other beneficial bugs, so you may not want to add them to your biocontrol mix if you’re using midge larvae.

Parasitoid wasps hold a special place in my heart as I used to work with a number of them for invasive species management. But there are a few things to take into consideration before you release them into your greenhouse. You typically want to start releasing wasps prophylactically. Many of these wasps have a difficult time stinging if aphids are crowded on a leaf, or they can get stuck in the honeydew of aphid populations that have been around awhile. Wasps are pickier about the species of aphids they attack, so these may not be a good place to start if you’re not sure which aphids you typically find in your greenhouses. If you know that you usually find green peach or melon aphids, you’ll want Aphidius colemani. If you have had more issues with foxglove aphids, go with Aphidius ervi. If you’re not sure, you can release both species at the same time and they won’t interfere with each other. Make sure to at least temporarily take down your sticky cards around the release date because, like other hymenoptera, they’re attracted to blue and yellow.

For more biological control options, check out Dr. Lily Calderwood’s factsheet “Getting Started with Biocontrol”.

Chemical options:

If you need to knock down a large aphid population and need to go the chemical route, UMass has a table of active ingredients that are effective against aphids and approved for use on greenhouse ornamentals. Since this information is out of Massachusetts, there may be some that aren’t registered in New York, so be sure to check on NYSPAD to make sure these products are okay to use in New York.

On the NYSPAD homepage, search “Products”.

Then you can search by the product’s trade name, or Advance Search to look up by active ingredient.

If you’ve already released biological control agents into your greenhouses, chemical applications will knock them back too, so you’ll have to keep a close eye on your aphid populations since those tend to bounce back more quickly than the beneficial insect populations.

New Resource Page – Becoming a Certified Pesticide Applicator in New York State

Applying for a pesticide applicator’s license can be confusing. Sometimes people don’t know where to start looking for information.

CAAHP’s Senior Commercial Ornamental Horticulture Educator, Lindsey Christianson, has written a resource page, showing would-be applicants where and how to find the information they need to start the application process for a pesticide applicator’s license.

This 2 hour multi-site WEBCAST meeting will provide information and resources available to local governments as they investigate issues related to enacting regulations for agriculture and animal owner-ship. With urban farming trends and more consumers concerned about their food sources, animals have infiltrated into village lots and beyond.

This class will be broadcast to 4 different locations, serving as a valuable springboard to local governments gathering knowledge and information.
