The 2020 NE-1640 meeting was held Sept. 16, 2021 at Gulf Shores, AL in conjunction with the Society of Nematologists annual meeting, with some participants joining via video conference due to the COVID-19 pandemic.

Administrative Advisor

Anton Beckerman reported on congressional budget progress and the increased appropriations proposed in the President’s budget.  He indicated that NIFA was doing more remote work, to achieve faster turn-around.  The REEPort system is moving to a new reporting system.  The annual and termination report should highlight publications and other outputs (grants written collaboratively, partnerships with industry, technologies, etc.) and distinguish Outputs versus Impacts.

Presentations

Koon-Hui Wang (Hawaii) reported on studies on crown and root rot of asparagus, with two trials evaluating soil amendments and effects on soil health. Results demonstrate that the adverse effects of fluopyram on soil health can be mitigated with sunn hemp as a green manure crop.  Biological stimulants (shrimp shell meal, crustacean meal, or chitosan drench) enhanced soil health while reducing Fusarium wilt.  Numerous outreach events and a YouTube channel facilitated outreach education on cover crops and soil health management.

Carmen Ugarte (Illinois) surveyed plant parasitic nematodes in fields with short (3 years) versus long (< 5 years) corn-soybean-small grain rotations.  Higher soybean cyst nematode numbers occurred in fields with short rotations, whereas fields with long rotations had more free-living nematodes and more spiral and dagger nematodes.

Frank Hay (Cornell) assessed garlic cloves for bloat nematode (Ditylenchus dipsaci) and found heat treatment reduced nematode populations by 88-99 %, but was unable to eradicate the nematode from seed cloves. He also evaluated new methods for extracting nematode DNA from soil to improve diagnostics for root knot nematode, Meloidogyne hapla, and refined damage thresholds for M. hapla on tolerant potato varieties, reducing the need for nematicides.

Ernest Bernard (Tennessee) surveyed grapes and found plant parasitic nematodes in 54 of 55 vineyards surveyed.  Important pathogens included lesion, dagger and root knot nematodes.  Meloidogyne enterolobi was not detected in any surveys in Tennessee.  Hemp cultivars were evaluated for resistance to M. incognita, and found that varieties T1 and WIFE were almost immune, while Charlottes Web and Remission were susceptible, supporting high reproduction. Susceptibility was not correlated to canabinoid levels.

Rob Wick (Massachusetts) reported finding a new root knot nematode species on turf grass in New Hampshire.  He tested several proprietary compounds for nematode control in turf, but did not find useful levels of population reduction.  He also identified Bursaphelenchus antoniae from white pine in Massachusetts, the first report of this species in North America.

Andreas Westphal (California) evaluated application methods of allyisothiocyanate compounds as a biofumigant, as well as chemical nematicides in almond production.  Anaerobic Soil Disinfestation was very effective for lesion nematode control.  He also reported on use of a spray blade applicator for subsoil application of nematicides.  He began microplot experiments to evaluate various digestates (effluents of a biogas reactor).

Deb Neher (Vermont) conducted on-farm trials with Anaerobic Soil Disinfestation and vermicompost to reduce root diseases in lettuce.  Vermicompost was more effective at reducing disease than a commercial biocontrol product (RootShield) but was phytotoxic when used in planting mixes at greater than 5 % by volume.  Poultry based compost enhanced survival of enteric pathogens in soil more than dairy-based compost, which may affect organic certification decisions.

Billy Crow (Florida) continued multi-year trials of nematicides on turf grasses.  Fluopyram and abamectin give good control of sting (Belonolaimus) and root knot nematodes.  These are less effective against Lance nematode (Hoplolaimus), and turf quality declines when lance nematodes exceed 100-300/100 cc soil.  The miticide chlorfenapyr was effective for control of foliar nematode (Aphelenchoides besseyi).  A related species (A. pseudobessyi) was associated with green stem and foliar retention in soybean.

James Lamondia (Connecticut) used tobacco cyst nematode (Globodera tabacum) as a model for pale cyst nematode on potato (G. pallida). A solanaceous weed, Solanum sisymbriifolium (sticky nightshade or Litchi tomato) has been evaluated for ability to stimulate hatch of G. tabacum in comparison to a susceptible or resistant host plant, for ability of the nematode to reproduce and increase, and for efficacy against the nematode as a trap crop under field conditions in comparison to plant resistance.  Litchi tomato was more effective in reducing nematode numbers than non-host rotation and use of a resistant variety.  Control was as effective as expected for soil fumigation.  Surveys for beech leaf disease (Litylenchus crenatae) found this pest in new areas after the first report in 2020.  Tree injection with oxamyl reduced  nematode populations in leaves. 

Lesley Schumacher (USDA-Tennessee) has begun screening soybean germplasm for soybean cyst nematode resistance, and integration of these cultivars with cover crop management and seed treatments.  She is determining population densities of nematodes and their relationships  with rotifers, Collembola, mites and oligochaetes to evaluate associations with soil health.

Nathaniel Mitkowski (Rhode Island) described results of trials that supported earlier reports of poor efficacy of fluopyram against lance nematode, but found that Salibro (fluazaindolizine) was effective.  Abamectin has activity, but rarely penetrated deeper than one inch as it binds to surface organic matter in turf.  The beech leaf disease (Litylenchus crenatae) was most severe along streams and wet areas, or after prolonged high humidity (>2 weeks).

Marisol Quintanilla (Michigan) presented results of a four-year trial comparing soybean varieties with soybean cyst nematode resistance from Peking and PI 8878.  Rotating Peking and PI 88788 resulted in the lowest cyst nematode populations density, and highest yields. Cover crops with oilseed radish and ‘Dwarf Essex’ rape reduced lesion and root knot nematodes.  Fields with the lesion nematode Pratylenchus penetrans had reduced carrot root weight, whereas fields with P. neglectus and P. crenatus had less damage.  Studies are underway to establish unique damage thresholds for the three species.  Additional studies evaluated composts and nematicides for managing root knot neamtode in day lily and lesion nematode in potato.  The entomogenous nematode Steinernema feltiae reduced emergence of the spotted wing Drosophila, but S. carpocapsae and Heterorhabditis bacteriophora did not.

George Bird (Michigan) proposed that thermal stability was a useful parameter to indicate soil health in potato fields. Fields with cool and stable conditions were associated with higher potato yields and higher Cornell University soil health indicators that fields with hot stable conditions or nonprofitable yields. The Soybean Cyst Nematode (SCN) Coalition, a public/private partnership of 28 states and 8 corporations, implemented a statistically valid pre-post program survey of more than 1,000 soybean growers in 17 states to determine the impact of the program since its launch in 2018. The results show that the proportion of soybean growers rotating with non-host crops has increased 6%, rotation of sources of SCN resistance has increased 10%, ability to identify Peking as an alternative source of resistance has increased 10%, use of SCN protective seed treatments has increased 18% and overall use of SCN resistant varieties has increased 7%. In addition, 55-76% of the growers were able to recall Coalition specific educational messages. Grower most trusted sources for SCN information included the agricultural media (43%), Extension (38%) and seed dealers (37%). A 60-day campaign for six new SCN Coalition videos resulted in more than 900,000 views.   Potential trap crops prevented reproduction of SCH HG Type 1.2, and six grower field trials were initiated in 2021.

James Kotcon (West Virginia) evaluated amendments to agar media to assay for nematode trapping fungi.  Urea in water agar increased trap formation by the fungi Arthrobotrys and Dactylaria, but had less effect in quarter-strength corn meal agar.  The best recovery occurred with both urea and bait nematodes added to plates, but trap formation was quite variable.  Birdsfoot trefoil pastures were helpful in suppressing the sheep intestinal parasite, Haemonchus contortus), and lambs grazing birdsfoot trefoil had lower levels of infection, and better weight gain than lambs on orchard grass and clover pastures.

Multi-State Impact Statements Workshop

Sarah Delheimer (Colorado State University) presented a workshop on writing effective Impact Statements.  These should include a brief summary of the work and why it matters.  That may include a change in knowledge, skills or behavior by the targeted stakeholders.  Output statements should focus on the issue and accomplishments.  Impact Statements should define when and where the impact occurred and who benefited.

Business Meeting

Billy Crowe was elected as Secretary for the first year (2021-22) of the new NE-2140 project, and Ernest Bernard will serve as Chair.

An invitation from Florida to host the 2022 meeting was accepted unanimously. 

Preparation of a termination report was discussed and Nathaniel Mitkowski agreed to circulate the report template.  The report is to be filed in the old NIMSS system.

A resolution of appreciation to Billy Crowe was adopted unanimously in recognition of his service as local arrangements host for the meeting.

Billy Crowe moved to adjourn, Nathaniel Mitkowski seconded, and the motion caried. The meeting adjourned at 4:46 PM.

Multistate Project NE-1640 Termination Report

Title: Plant-Parasitic Nematode Management as a Component of Sustainable Soil Health Programs in Horticultural and Field Crop Production Systems

Period Covered: 10-01-2016 to 09-30-2021

Date of this report: 28 February 2022

Accomplishments

Short-Term Outcomes

Objective 1. Develop and integrate management tactics for control of plant-parasitic nematodes including biological, cultural (such as rotation or cover crops and plant resistance), and chemical controls.

Following the 2018 NE-1640 SCN short course in New York, this nematode has been confirmed for the first time in 29 additional counties. At the beginning of NE-1640, SCN had only been detected on one county in New York. 

In 2018 in CA, protocols for anaerobic soil disinfestation (ASD) were optimized to allow for nematode reductions to fie ft depth when done at the proper time of year.

In 2019 in CA, limitation of the time of year for successful use of ASD were determined, and feasibility of use in orchard versus vineyard soil were recognized.

The most effect pesticide is ineffective if it does not come in contact with the target pest. Studies on the behavior and vertical migration of the key plant-parasitic nematodes on warm-season turfgrasses (grass root-knot, sting, and lance nematodes) showed an interaction with the mobility and persistence of turfgrass nematicides.  Abamectin remained in the top 2 cm of turf profile, the same region where the grass root-knot nematode proliferates.  Therefore, abamectin can be used effectively for grass root-knot nematode on turfgrasses but is not very effective on nematodes such as sting nematode that inhabit deeper in the soil profile. Fluopyram nematicide is more mobile than abamectin and moves deeper into the turf profile over time.  Therefore, fluopyram can provide good control of sting nematode but only temporary control of grass root-knot nematode.  This research was key in understanding how to best use these nematicides against key nematode pests and the research results were incorporated into extension publications, articles in trade publications, and dozens of seminars presented in FL, GA, SC, TX, AR, MO, and AL. 

New diagnostic procedures for root-knot nematodes on warm-season turfgrasses were developed and implemented.  Accurate diagnosis of these nematodes leads to improved management by targeting the correct pest.  This, in turn, yields reduction in labor costs, water use, fertilizer use, and use of other pesticides.

New risk thresholds for lance nematodes to warm-season turfgrasses were developed and implemented. Accurate diagnosis of these nematodes leads to improved management by targeting the correct pest.  This, in turn, yields reduction in labor costs, water use, fertilizer use, and use of other pesticides

A new species of foliar nematode (Aphelenchoides pseudobessyi) from ornamental plants in nurseries and landscapes in Florida as well as from soybean in Brazil was described.  This leads to new research on the potential risk this nematode has on US soybean and other crops.

A new species of root nematode (Hirschmanniella dicksoni) from limpgrass pastures in Florida was described.   The virulence and host range of this nematode are currently unknown, but will be investigated in future trials.

Weed hosts for multiple species of nematodes were identified.  Through targeted weed management, nematode pest problems on crops and nematicide use can be reduced.

Comand® Compost was shown to improve turfgrass tolerance to sting nematode and in some cases to suppress sting nematode activity and reproduction.  Incorporation of Comand Compost prior to planting has become a standard practice for sting nematode suppression on athletic fields and golf courses in Florida.

Evaluation of bermudagrass germplasm tolerance to sting nematode has led to TifTuf being recognized as the most tolerant cultivar available. This cultivar is now the cultivar of choice for use on high-end athletic fields in the southeast, leading to reduced risk of player injuries and reduced nematicide use.

Replicated on-farm trials demonstrated two approaches for reducing inoculum load of soilborne pathogens for lettuce production: anaerobic soil disinfestation and blending vermicompost in starter mix.

Some compost blends evaluated in Michigan have high nematicidal activity.  The LAB blend from Morgan Composting, kills 100% of root lesion nematodes even at a 5% concentration, in addition, poultry manure is also effective. 

In soybeans, trials have demonstrated that rotating different sources of resistance to Soybean Cyst Nematode (SCN) reduces SCN numbers and increases yield.  Using the same sources of resistance year after year leads to yield decreases and nematode increases on the previously resistant varieties.  Seed treatment nematicides have not decreased SCN numbers or increased yield. We found that the Peking source of resistance is especially susceptible to SCN overcoming resistance, but it does excellent in rotation with the PI88788 source of resistance. 

Soybean germplasm was obtained from collection curator for bioassay and bioassay work continued to identify new potential sources of resistance to soybean cyst nematode populations.  Breeding lines from Uniform Soybean Tests-Southern States and ARS breeding lines were evaluated for response to soybean cyst nematode populations.  Soil samples collected from Tennessee soybean production fields were assayed soil for soybean cyst nematode, other plant-parasitic nematodes, and free-living nematodes. 

Several species of root lesion nematodes have been found in carrot fields using new molecular tools, which had previously been assumed to be Pratylenchus penetrans. Yield losses differ among species, and work is now underway to determine the damage threshold of each species and to further understand the biology of each and the impact of rotation crops.

Effective cover crop varieties to reduce root lesion nematode have been identified, and may reduce problems with these nematodes in carrots, potatoes, fruits, and other crops. 

Globodera tabacum is useful as a substitute model for the quarantined pathogen Globodera pallida for trap cropping experiments with S. sisymbriifolium under field conditions.  These experiments demonstrated that trap cropping can be as or more effective than soil fumigation for nematode management.

An ongoing ornamental project with an industry partner is evaluating solutions for Northern root knot nematodes in daylilies.  This problem causes nearly 20% loss in profit annually. Use of dips before planting or drenches with products such as Fluopyram and Neem based nematicides, in addition to hot water dips of the planting material give excellent control.

Objective 2. Determine the ecological interactions between nematode populations, nematode communities, ecosystems and soil health.

Thermal stability is being proposed as a new soil indicator for potato production.  Cool and stable conditions were associated with higher tuber yields and higher Cornell University soil health indicators than those associated with non-profitable yields and hot and stable thermal stability conditions.   

Relatively complex food webs, containing fungi and fungivorous nematodes, correspond with natural suppression in this field with no-till monoculture soybean.

Poultry based compost enhanced survival of enteric pathogens in soil more than dairy-based compost. This may shift the choice away from poultry products that are currently used by vegetable farmers for economic reasons, and may affect their acceptance by organic certification programs.

A long-term crop rotation trial in West Virginia demonstrated increased levels of nematode biocontrol agent activity in soils amended with compost.  Longer rotations also promoted soil suppressiveness.

Objective 3. Outreach and communication - Compile and present/ publish guidance on nematode management and management effects on soil health for different crops under different conditions.

The SCN Coalition public/private partnership of 28 states and 8 corporations implemented a statistically valid pre-post program survey of more thana 1,000 soybean growers in 17 states to determine the impact of the program since its launch in 2018.  The results show that soybean growers rotating with non-host crops has increased 6%, rotation of sources of SCN resistance has increased 10%, ability to identify Peking as an alternative source of resistance has increased 10%, use of SCN protective seed treatments has increased 18% and overall use of SCN resistant varieties has increased 7%.  In addition, 55-76% of the growers were able to recall Coalition specific educational messages.  Grower most trusted sources for SCN information included the agricultural media (43%), Extension (38%) and seed dealers (37%).    A 60-day campaign for six new SCN Coalition videos resulted in more than 900,000 views.  Regular Coalition press releases and media interviews keep its active management messaging in front of its target audience. Since The Coalition’s launch, it has established a 15.24% share of discussion through its traditional media outreach to result in 21.4 million potential impressions among North America’s soybean growers and agronomists. The Coalition won the 2020 Best of Show National Agri-Marketing Association (NAMA) award in Public Relations for its media relations campaign.

UF Nematode Assay Lab became integrated into the National Plant Diagnostic Network through development of a new database.  All pest nematode detections are now automatically provided to NPDN and are available for pest mapping and mega data analysis.

Growers are changing their practices because of our research, and we receive calls from ag professionals, and growers in other states and countries to provide them information on what we do. 

An ongoing ornamental project with Walter’s Gardens in Michigan, we are working toward a solution for Northern root knot nematodes in daylilies, a problem that causes nearly 20% loss in profit annually. We have found excellent control methods, such as use of dips before planting or drenches with products such as Fluopyram and Neem based nematicides, in addition to hot water dips of the planting material.  We have also evaluated cover crops and the industry has modified their management practices according to our recommendations. 

NE-1640 participants generated over 300 publications, including peer-reviewed scientific publications, two books, and numerous book chapters, and numerous Extension publications, videos, podcasts, and articles in grower and trade periodicals.

ACOMPLISHED MILESTONES: 

New nematicides have been evaluated for efficacy, and nematode-specific recommendations are now available in key crops.

The role of composts in developing nematode-suppressive soils has been characterized in MI, VT and WV, but the microbial communities that induce suppressiveness will need further elucidation.

Cover crop experiments have validated appropriate rotations in several crops.  Nematode suppressiveness increased in long-term studies.

New nematode diagnostic and management recommendations have been integrated into outreach programs.

Results have been reported extensively to stakeholders and at professional meetings, and research has been published in peer-reviewed journals.

The first two of the Objective 3. short course milestones were completed in 2018 as originally planned.  Because of COVID-19 and NE-1640 personnel changes, it was not possible to hold the remaining three short courses in 2019, 2020 and 2021.
