Brief Summary of Minutes of Annual Meeting

2020 meeting discussion. Money left over from the San Antonio meeting was transferred to Kelly Tillman to subsidize this meeting. Location for 2020 meeting will be in Madison, Wisconsin hosted by Bryan Jensen- dates will January 21, 2022 January 23, 2020 -selected and voted for. All were in favor. Discussion occurred on the meeting time because of the government shut down but committee decided not to change the time or date at this time hoping the government would not shut down next year. Andy discussed state report submission via a website or a fill-in PDF form for the 2020 meeting. The objective is to make it easier for the secretary and to make it standardized for everyone. We will need to include an extra section for those who want to include other things. And there should be a standard citation section as well. Industry wants copies of our state reports and there was discussion of whether they should be allowed. It was decided to refer them to the website of NC 246 as we publish our reports and make them public. There was also discussion about industry wanting a copy of our state reports before they come in for their session. Nothing was proposed on this. It was noted that the meeting with industries to exchange information and industry can choose to attend and have a focused discussion or not.

2020 Rewrite. It was noted that we need a new draft agreement for the NC 246 and that the executive committee will be appointing subcommittees for the objectives. We were advised to make changes so it is understood we have made advances and to not make objectives overly complicated to help the government review team. September 30 submit the list of participants, select a leader, form a writing team, format is listed on the NCERA site. Contact Christa Hamilton to walk us through it. Objectives need to be revised and tweaked by September 30 to October 1 new project due.

Monitoring for Bt resistance. Collecting from Bt corn is becoming an issue and attorneys will not let you keep any data from that. Companies could block this and cause problems when we try to make the data public. There was discussion on the 5% refuge for single Bt traits and how it should not be allowed anymore. We were told it was being phased out by the companies but exact details were not given. Community refuge idea was brought up again for ear feeding caterpillars. Resistance monitoring issues were brought up as well including the fact that we, as scientists, monitor for resistance issues, but perhaps that is more of something the companies should be doing. It was suggested by industry that we should focus more on new ideas, preventing issues, and creating a successful IRM plan for ear feeding pests.  Sentinel plots were briefly discussed and putting these in the greatest hotspots. We discussed putting out a methods paper that companies can use and refer back to. The reason being is we are the experts on corn pests. We should include where to collect, what bioassays to use, and the different levels that should be expected from each of the bioassays. We should include what mitigation action against the Bt failures is acceptable to us and what we recommend. We should discuss what a standard sentinel plot would look like. What is the differences and if true isolines are available for each of these for sentinel plots? Are there true isolines for sweetcorn? It was discussed that we have less than 10 years for Vip and that long-term IRM is not possible for Bt‘s anymore. The creation of a methods paper on monitoring for Bt resistance as an official entity. Companies can use this as standard.  Juan Luis-fall armyworm genomes have been sequenced from different regions. DNA based monitoring set of markers for frequency of alleles is needed. Noted was possible Cry1A and Cry1F toxin receptor mutations. How can we detect mutations? For Vip- what is the threshold for unexpected damage, EPA wants to know. We need a harmonized message and shared BMPs.

We need sentinel plots to detect Vip resistance. For refuge management, why plant refuge if the farmers can’t see the difference. Bayer/Monsanto noted that there are standalone roundup ready varieties with good yields and they have lots of unsold inventory. “So where is the need that we keep talking about?” We need a proposal in writing for Vip resistance monitoring for ABSTC to be included are toxins needed from the companies, the right germ plasm from the companies. *This should be an issue brought up at the International Corn Summit. *

Where do we stand on these?

• What would successful resistance monitoring look like for each of the species as this is not even standard across the board.
• What is our own definition of resistance?
• What does successful IRM for ear feeding pests look like.
• What should be the proper mitigation of Bt failure?
• We need a threshold for “additional action necessary” for being proactive.

 Note: How Corteva deals with UXD. Corteva said there is less than 1% that is single trait toxins. Corteva makes an effort to talk to neighbor of growers about BMPs. They inform the EPA within 30 days of confirmation of resistance. They inform local extension agents, growers and, experts in the area. Their mitigation area is half mile with an unexpected damage area.

For ABSTC the definition of resistance is not as important as the “action threshold”. The threshold of action to nip it in the bud as soon as complaint comes in. They mentioned the more regulation the worse the problem will be.  However, we noted that the frequency of resistance alleles in a population is important so that should be monitored.

A discussion on the BMP before resistance occurs. ABSTC wants us to research what to do after resistance is found. It was mentioned that a priority should be to lower selection pressure first. Pointing out resistance issues is important but this is more reactive and what they want is more predictive or proactive approach. Part of this involves product selection which is still very important as well as monitoring.

Our BMP’s: We have assumptions about the Bt refuge and how and why to use it. We need to make sure ag professionals understand this. If pests aren’t there, don’t use the pest product. Scouting is important. Not using a same product every year. If we could predict where past populations are, we could put the right product down although this can be very hard to predict. What is the economic impact of the BMPs?  We need to be able to communicate value over time regarding the BMP’s. Farmers think more on this year’s yield and less on long-term durability. It is important to not put so much emphasis on the insect pest itself but also on resistance to the pathogen it transmits. Planting dates with certain traits, for example use Vip only in late planted corn. Find out what the pests are really doing, for example cannibalism in Bt- corn earworm get too sick to eat each other when feeling on Bt’s. Are there any conventional seed sources with resistance?

Bagtag agreements. The permission to do Bt tests and general use was discussed. Pat Porter brought up the bag tag agreement again and we need to update the relaxed service agreements as well as our master service agreement for our specific universities. Do we know who our contract negotiation officer is in our research offices? We need to know who specifically in each of the companies we need to contact for these. We went through our master service agreement template and completely updated it. However, it was stated by the companies that the one we came up with is too specific and the lawyers would have it for years. They asked us to redo to be more general. However, it was discussed that we don’t gain protections from general guidelines. Side note: Are sentinel plots in the agreements?

Non-Bt and non-treated seed. It was stated that farmers do not usually know what they are planting and that volunteer corn is and has been an issue. It was noted that sellers are also not aware of the actual traits they are selling at times. It was stated that names of toxins are not important to farmers and that this information on toxins is hard to find. It was noted that companies develop programs or packages so farmers aren’t bogged down in the details and they don’t have to think about these things as they are provided in a package form. It was noted again that monitoring needs to go into the decision but that it’s driven by economics. The availability of non-Bt corn is still an issue. Pennsylvania and Michigan and other fringe states have greater availability of the none Bt corn. We need to put together an informational survey and find out what knowledge is out there on Bt usage. This should include what the traits are, what they control and when to use Bt traits. Variety testing at universities is usually conducted with Bts so we have no information on the comparison of a non-Bt varieties. What is the benefit of variety testing -if you include information on return on investments, monitoring costs, scouting costs, it may be economically viable to use non-Bt. Seed treatment costs add to the cost of the seed overall and these are usually to control secondary pests which are only a minor issue. We need an analysis that will include the cost for pest management yet extract the Bt costs- note this may be difficult. The goal would be to show if there’s a dramatic overpayment-cost-and yield potential’s for different areas. It was noted that it is hard to break even when using seed treatments. How do we figure in incentive costs like buying early? Then put this model out.  Christian Krupke has taken the lead on this subcommittee to create a spreadsheet for economic models for seed treatment costs. Kelly Hambee-Delaware has information on in furrow versus seed treatments.

Extension meetings versus company meetings. Confusion occurs when extension and companies have different views for ag professionals. Perhaps there is different audiences at extension meetings versus company meetings. Extension meetings are sometimes plagued with problems like low attendees, attendees may only show if we offer CCE credits and use giveaways. Some universities are charging which some may prefer since it sends a message of worth. Extension messages tend to be more complex while industry has simple messages. Companies tend to have more streamlined communication while extension has a greater frequency of meetings. There are more community county extension meetings and only four from Pioneer for example. Meetings that are more friends and neighbors tend to be better attended. Information is readily available online, why come to a meeting. Folks too busy to attend. We offer unbiased information about products. Independent consultants can be a big help in getting out good information. We need better news and electronic newsletters. We need to provide the farmers’ problems with real solutions. Training new faculty is important and to get them connected to our group. We develop stuff, put it out there everyone uses it without credit to us-bad?, good? QR code to get us two extension stuff printed materials faster? Printed materials, free cards and info still relevant despite online availability. PDFs easier to read.

WCR permit. The permit was discussed. What would we like to see in terms of a permit wording? Add in Mexican corn route worm for the south. Explain wild type versus non-wild type with references. Who will lead the new permit writing? We need an update of Wade his position and to send a letter of support for the colonies.

Insecticide resistance and monitoring. We need to add in bees and exposure to sprays for the rewrite, include pyrethroids and adjuvants and how they affect pollinators. We need 1) proactive resistance monitoring for insecticides 2) coordinate standard assays across different universities 3) proactively monitor.

NC246 organized a Western Bean Cutworm (WBC) Summit in conjunction with the Entomological Society of America (ESA) National Meeting in Vancouver, BC on November 10, 2018.  Twenty-eight participants from biotech seed corn companies, regulatory agencies (US-EPA and USDA-APHIS), and federal (USDA-ARS) and universities convened to discuss current difficulties producers encounter in the control of WBC.  This meeting among major stakeholders reviewed the status of current knowledge of WBC biology, ecology, and management tactics in relation to the efficacy of integrated pest management (IPM) and insect resistance management (IRM) tactics.  Moreover, a meeting report was distributed which outlined the inadequacies of IRM and IPM strategies, and developed priorities for future research.

 

NC246 members organized a Western Bean Cutworm Symposium held in conjunction with the 9th International IPM Symposium on March 21, 2018 in Baltimore, MD, with the goal to improve understanding of the IPM issues surrounding WBC.  This symposium program had six invited presenters from across the United States, Canada, and Mexico, along with a concurrent poster and extension materials session.  Presentations were taped and videos of the oral, poster, and extension presentations were made available for public viewing.

 

NC246 members organized a symposium entitled “Current Research on the Biology and Management of Insect Pests in Corn: Crossing Borders from Genes to Populations” at the ESA National Meeting on November 13, 2018.  These presentations by NC246 members showcased research performed by committee members, and communicated outcomes and impacts to an audience of international stakeholders.

 

The Handy Bt Trait Table at https://www.texasinsects.org/bt-corn-trait-table.html is an independent unbiased source of information regarding the Bacillus thuringiensis (Bt) protein toxins in all commercially available corn hybrids.  The updated version for 2018 received nearly 2,300 unique page views from states across the entire Corn Belt within the first few days.  The trait table is also free for distribution in magazines, extension bulletins, and meetings.  This is an important one-stop source of unbiased information about trait packages to aid farmers in selecting seed traits.
