US EPA’s Proposal to Prevent Western Corn Rootworm Resistance: Does IPM Implementation Have a Realistic Chance?

On January 28, 2015, the United States Environmental Protection Agency (US EPA)  published a “proposed framework to prevent corn rootworm resistance.” Public comments were sought across an original 45-day period that was extended 30 days beyond the original March 16, 2015 deadline. Within the proposal, the United State EPA acknowledges that corn rootworms have already developed resistance to “Bt corn” in some areas of Iowa and Illinois. US EPA has characterized some states within the Corn Belt as in the “red zone” and these include Iowa, Illinois, Nebraska, western Indiana, southwestern Wisconsin, southern Minnesota, and eastern South Dakota. The so-called “red zone” states are described by the US EPA as follows: “where corn rootworm infestations are common and the use of Bt corn is high, …” The Agency’s proposal also adds that producers may be part of the “red zone” if the following circumstances are met: 1) “corn-on-corn for multiple years”, 2) “heavy use of Bt corn”, 3) “regular corn rootworm infestations”, and 4) “spotty compliance with current refuge requirements.” As part of the US EPA’s proposed framework they offer the following proposal: “In areas at risk for corn rootworm resistance, to require crop rotation, use of corn varieties containing more than one Bt protein, or other integrated pest management (IPM) strategies and stewardship for corn rootworm.” Additionally, the US EPA proposes the following: “70% of corn acres in the “red zone” should take part in IPM efforts and that 50% of corn acres in non-”red zone” areas should participate in IPM efforts.” From my perspective, isn’t this setting the bar a bit low? Why not propose that some form of IPM be put in place on 100% of corn acres regardless of zone characterization?

In reaction to this US EPA proposal, not surprisingly, numerous comments have been received and published including a letter that I signed along with 14 other entomologists from 12 prominent institutions. I encourage you to review these comments from many individuals and organizations. As you will see, there are many different perspectives and opinions taken on this controversial proposal. Among the many concerns raised by the proposal are those that involve the use of a planting-time soil insecticide with Bt hybrids. Let me be clear — planting-time soil insecticides should be considered an important arrow in the IPM quiver targeted at the corn rootworm complex.However, the addition of a planting-time soil insecticide along with a corn rootworm Bt hybrid is not a good resistance management strategy. The authors of two recently published journal articles have confirmed that use of a planting-time soil insecticide with a rootworm Bt hybrid delays emergence and increases the chances of non-random mating (promotes assortative mating); thereby, hastening the onset of resistance to Bt proteins. The citations for these journal articles are provided below:

Petzold-Maxwell, J.L. et al. 2013. Effect of Bt maize and soil insecticides on yield, injury, and rootworm survival: implications for resistance management. Journal of Economic Entomology 106(5): 1941-1951.

Frank, D.L. et al. 2015. Effect of seed blends and soil-insecticide on western and northern corn rootworm emergence from mCry3A + eCry3.1Ab Bt maize. Journal of Economic Entomology DOI: 10.1093/jee/tov081

Planting-time soil insecticides will remain an important tool targeted at the secondary insect complex when present at economically threatening levels. They also represent an important option when used with non-Bt hybrids in fields with corn rootworm infestations. When a planting-time soil insecticide is used with a pyramided Bt rootworm hybrid for the sole purpose of rootworm protection, it’s hard to find any convincing argument that this is a good IPM or resistance management (IRM) approach.

Resistance by many pests, including corn rootworms, has occurred when we have used the same arrow over and over again and failed to integrate management tactics. Since 2003, the year in which Bt rootworm hybrids were commercialized, growers have increasingly failed to integrate tactics and have relied upon a narrow set of Bt rootworm proteins expressed at low levels within a refuge system designed for high-dose events targeted at European corn borers. We should not have been surprised when reports of western corn rootworm resistance to Bt corn began to occur in Iowa soon followed by Illinois. Finally, while I am supportive of crop rotation as a viable pest management tactic for corn rootworms in many areas of the Corn Belt, growers in east central and northeastern counties of Illinois recognize that a segment of the western corn rootworm population in those areas is now resistant to two Bt proteins (Cry3Bb1 and mCry3A) as well as crop rotation. Rotation, even in those Illinois counties, remains a good strategy; however, other tactics will need to be more fully integrated into a long-term corn rootworm management program.

Black Cutworm Moth Captures Common in Several Midwestern States

Impressive flights of black cutworm and armyworm moths have been reported by Doug Johnson an Extension Entomologist at the University of Kentucky . Entomologists at Purdue University also have received reports that black cutworm moth captures are now common in many areas of Indiana. Kelly Estes, Agricultural Pest Survey Coordinator with the Illinois Natural History Survey, has established a network of trapping cooperators across Illinois. Although no intense flights (nine or more moths caught over a 2-day period) of black cutworm moths have been reported by these cooperators, captures of this species have been common the past two weeks in the following counties: Champaign, Fayette, Logan, Lee, Macon, Macoupin, and Madison. This distribution of captures suggests that black cutworm moth flights have likely taken place throughout Illinois and growers are encouraged to remain vigilant for early signs of leaf feeding when corn seedlings begin to emerge. Today (April 21) strong winds from the south are undoubtedly bringing many black cutworm moths into Illinois and fields like the one featured in the photograph below will be prime targets for egg laying by this species.

Champaign County field considered a prime target for black cutworm moth egg laying, April 21, 2015.

 

For more complete information about the biology, life cycle, and management of black cutworms and armyworms, fact sheets are available from the Department of Crop Sciences, UIUC. Provided below is a brief overview of some key life cycle and management facts concerning black cutworms.

  • Black cutworm moths are strong migratory insects with northward flights commonly observed from Gulf States into the Midwest from March through May.
  • Moths are attracted to fields heavily infested with weeds such as chickweed, shepherd’s purse, peppergrass, and yellow rocket.
  • Late tillage and planting tends to increase the susceptibility of fields to black cutworm infestations.
  • Cutting of corn plants begins when larvae reach the 4th instar — with a single cutworm cutting an average of 3 to 4 plants during its larval development.
  • Cutting tends to occur most often during nights or on dark overcast days.
  • Fields at greatest risk to cutting and economic damage are in the 1-to-4 leaf stage of plant development.
  • An early warning sign of potential economic damage includes small pinhole feeding injury in leaves (caused by the first 3 instars).
  • A nominal threshold of 3% cutting of plants has traditionally been used as a point at which growers should consider a rescue treatment.
  • Not all Bt hybrids offer adequate protection against black cutworm damage. Growers should consult the Handy Bt trait table prepared by Dr. Chris DiFonzo at Michigan State University to determine the level of protection provided by their chosen Bt hybrid.

As the season progresses, if you learn of significant black cutworm infestations, please let me know and I will share this information with the readers of this Bulletin.

Newly Published Report Confirms Extensive Use of Insecticidal Seed Treatments in Field Crops

On March 20, 2015, an article published in Environmental Science and Technology confirmed the extensive use of neonicotinoids as insecticidal seed treatments in a wide variety of field crops across the United States. The authors of the article Margaret R. Douglas and John F. Tooker are scientists with the Department of Entomology at The Pennsylvania State University.

Provided below are some direct quotes from their journal article concerning neonicotinoid seed treatments (NSTs):

  • “Neonicotinoid use increased rapidly between 2003 and 2011, as seed-applied products were introduced in field crops, marking an unprecedented shift toward large-scale, preemptive insecticide use: 34-44% of soybeans and 79-100% of maize hectares were treated in 2011. This finding contradicts recent analyses, which concluded that insecticides are used today on fewer maize hectares that a decade or two ago.”
  • “Importantly, the introduction of NSTs closely followed introduction of Bt hybrids targeting corn rootworms (Diabrotica spp.), a pest complex that has historically driven insecticide use in U.S. maize.”
  • “Importantly, however, NSTs are now used on almost triple the area historically treated with non-seed insecticides; therefore, NSTs (together with Bt hybrids) have more than displaced non-seed treatment insecticide use on an area basis.”
  • “This finding supports the apparent shift toward an “insurance” paradigm of pest management in maize, in which transgenic crops and NSTs are deployed even when target pest densities are expected to be low. This notion is also supported by a recent survey, in which 39% of maize growers using NSTs were not targeting any particular pest.”
  • “Several analyses on the influence of Bt crops on pesticide-use patterns do not seem to have considered seed treatments, and so may have overstated reductions in insecticide use (especially “area treated”) associated with this technology.”

The widespread insurance-based approach to the use of NSTs is likely to persist in corn and escalate in soybean production due to (as the authors of the current journal article point out) — “current incentives and disincentives for farmers and seed suppliers.” As a result, concerns will linger regarding secondary-insect resistance development and potential negative environmental consequences.

2015 Handy Bt Trait Table Now Available

In the transgenic era, the most important insect management decision a corn producer makes is deciding which type of corn hybrid to plant — a Bt hybrid or a non-Bt hybrid? This decision is typically made in the fall or early winter, well before planting ensues. In a sense, a producer who elects to plant a Bt hybrid takes out an insurance plan against a wide range of insect pests for the upcoming growing season. I have referred to this in previous Bulletin articles as — insurance pest management, the new and most popular form of IPM across the Corn Belt. According to the USDA Economic Research Service, 80% of corn grown in the United States during 2014 was a Bt hybrid.

Once again, we have Professor Chris DiFonzo, Department of Entomology, Michigan State University, to thank for preparing an updated Handy Bt Trait Table. Within this table Professor DiFonzo provides information on trade and event names, specific Cry proteins expressed, refuge requirements, herbicide tolerance characteristics, and targeted insect species. Producers are encouraged to pay particular attention to whether or not a specific Bt hybrid offers control or suppression of a given insect pest. Many of the Bt hybrids now offer a wide range of insect protection above ground (e.g. European corn borer, black cutworm, fall armyworm, corn earworm, stalk borer, western bean cutworm) and below ground (corn rootworm). In addition, producers need to ensure that they are deploying the proper refuge with their Bt hybrid of choice. Although seed blend refuges (5% and 10%) are becoming more common, use of some Bt hybrids requires a structured refuge. The level of complexity regarding refuge requirements for the wide variety of Bt hybrids has increased in recent years.

Recently, bioassays conducted by Dr. Joe Spencer, an entomologist with the Illinois Natural History Survey, have confirmed western corn rootworm resistance to the Cry3Bb1 protein in several Illinois counties (Henry, Kankakee, Livingston, McDonough, Mercer, Sangamon, and Whiteside). A segment of the western corn rootworm population has developed cross resistance to the mCry3A protein and resistance to crop rotation in Kankakee and Livingston counties. Producers who have not been satisfied with the level of root protection afforded by a Bt hybrid and suspect resistance, should consider planting a pyramided Bt rootworm hybrid — a hybrid that expresses more than one Cry protein targeted at corn rootworms. Crop rotation also should be considered by producers in fields with a history of continuous corn production. For producers who elect not to rotate crops, nor use a pyramided Bt rootworm hybrid, the planting of a non-Bt hybrid along with a planting-time soil insecticide is an option. The key to successful long term management of corn rootworms is utilization of an integrated approach — alternating tactics and thus hopefully avoiding resistance development. Unfortunately, the history of western corn rootworms is one of repeating past mistakes and development of resistance to nearly every management strategy.

A final note — black cutworm moths are migrating into the state of Illinois and growers who elect not to plant a Bt hybrid offering control against this pest should remain especially vigilant for early signs of leaf feeding once corn seedlings begin to emerge. Fields at most risk include those heavily infested with winter annual weeds.

US EPA Concludes Neonicotinoid Seed Treatments of Negligible Benefit to Soybean Production

On October 15, 2014, the US Environmental Protection Agency issued a report on the benefits of neonicotinoid insecticidal seed treatments to soybean production in the United States. Neonicotinoid insecticidal seed treatments include imidacloprid, thiamethoxam, and clothianidin. The analysis concentrated only on the potential benefits of imidacloprid and thiamethoxam used as seed treatments. Although clothianidin is registered for use as a soybean seed treatment, the authors of the report considered its use “minor” as compared with the other two neonicotinoids. Provided below are interesting pieces of information that I pulled directly from the report.

  • “On average, from 2008-2012, neonicotinoid-treated seeds were applied on 30% of soybean acres, (with some individual years approaching 40% of soybean acres).” page 3
  • Within the Corn Belt (Illinois, Indiana, Iowa, Missouri, and Ohio, 2008-2012) 5, 413,000 and 5,368,000 acres of soybeans were planted with imidacloprid and thiamethoxam seed treatments, respectively. This translates into 433,600 and 151,700 pounds of imidacloprid and thiamethoxam, respectively, used during those years (2008-2012). page 4
  • Across the United States (2008-2012), 1,151,000 pounds of imidacloprid and thiamethoxam were used as seed treatments on soybeans. page 4
  • For this analysis, early-season insects were the primary focus and included many familiar Corn Belt pests such as soybean aphids, bean leaf beetles, cutworms, thrips, and some soil insects (e.g. wireworms, seedcorn maggots). page 5
  • “This analysis provides evidence that U.S. soybean growers derive limited to no benefit from neonicotinoid seed treatments in most instances. Published data indicate that most usage of neonicotinoid seed treatments does not protect soybean yield any better than doing no pest control.” page 13
  • “In cases where pest pressure does necessitate some type of insect control, efficacious alternatives are available for the key foliar pests of soybeans at a comparable cost per acre.” page 13

The authors of this EPA report acknowledge that use of neonicotinoids within soybeans is largely prophylactic — an insurance based form of pest management. In their analysis they estimate that insecticidal seed treatments cost on average approximately $7.50 per acre. They also point out that foliar insecticides labeled for use in soybeans generally cost less than $7 per acre (11 insecticides identified). In addition, the authors of this EPA report make the following assumptions on page 10:

  • “Nearly all soybean growers are already making foliar pesticide applications of some sort and thus have access to the necessary equipment for application. In addition, growers would not have to make an additional field pass as foliar alternative insecticides that target the same pest spectrum as neonicotinoid seed treatments are applied at the same time as a number of current foliar sprays (including herbicides, fungicides, miticides, etc.) and can be tank mixed. No yield gains are expected from neonicotinoid seed treatments, which means the only potential economic impact would be the cost of an insecticide used as a foliar spray.”

Some of these assumptions can be challenged, especially on very large farms across the Corn Belt in which many producers rely upon aerial applications of pesticides rather than making their own ground-based treatments. Additionally, the use of fungicides although increasingly common in recent years, is not routine within every Midwestern soybean field. Therefore, application of an insecticide and fungicide tank mix should not be considered a given on most soybean fields, nor should that of a herbicide and insecticide combination. The optimum time to apply a herbicide for weed control can vary considerably from that to deter insect damage.

Nonetheless, this informative report raises considerable doubt regarding the economic benefits of these insecticidal seed treatments to soybean producers. The use of insecticidal seed treatments within the soybean production system clearly functions as an insurance-based form of pest management. For large commercial farms across the Midwest landscape, many producers typically do not scout soybean fields and utilize economic thresholds to make management decisions for insect pests. Over the years, producers could save on insecticide costs within many Midwestern soybean fields by only treating when economic levels of a given insect pest surface. Yet, the long term trend regarding insect management within large-scale commercial corn and soybean production systems reveals an increasing reliance on product-based inputs (insecticidal seed treatments, Bt hybrids) versus labor and management costs (scouting and use of economic thresholds). It will be interesting to see if US EPA considers a similar analysis for these insecticidal seed treatments in corn production systems.
