Using Drones for Spray Application – Adoption Trends in US and Worldwide

Traditionally, aerial pesticide spraying worldwide has been done using conventional fixed-wing aircraft or helicopters with a pilot onboard. However, this is changing fast. Small, remotely piloted aircraft are being used to apply pesticides around the world, especially in East Asia (mainly China, Japan, and South Korea). For example, about 2,800 unmanned helicopters were registered as of March 2016 in Japan, spraying more than a third of the country’s rice fields. Although rice is the main crop treated with spray drones in Japan, use of drones to treat other crops such as wheat, oats, soybean, and other crops has been steadily increasing. According to one report, 30% of pesticide spraying in South Korea is done using drones.

Battle for the Belt – Season 2, Episode 1: Kick-Off

Year 2 of Battle for the Belt kicked-off with corn and soybean planting on March 25 at the Western Agricultural Research Station in Clark County: https://www.youtube.com/watch?v=H0ukx_RvOrI&list=PLYlh_BdeqniJ4J-htcJ9Z5MjULk3E8Eqk&index=1

Planting conditions were good with adequate soil moisture; however, soil temperature was in the low 40s at a two-inch depth. Planting will continue at the Northwest Agricultural Research Station in Wood County and Wooster Campus in Wayne County when soil moisture conditions allow.

The Battle for the Belt project seeks to answer several questions related to corn and soybean planting date management in Ohio:

  • Which crop has the smallest yield penalty for delayed planting?
  • Can we adjust management practices to mitigate losses due to late planting?
  • How are insects, diseases, weeds, and other factors affected by planting date?

For both soybean and corn, earlier planting is promoted to maximize yield. However, Ohio has a trend towards a lower number of suitable fieldwork days during planting season. With non-favorable weather, the planting date window is often short and disconnected. Farmers often ‘debate’ which crop should be planted first – corn or soybean. The ‘Battle for the Belt’ project is a field research and extension effort to help address the question, what crop should be planted first – corn or soybean?

This is the second year for the project. Project updates from last year are available on the OSU Agronomy YouTube channel (https://www.youtube.com/@OSUAgronomicCrops).

  • Ethanol production increased just slightly to 310 million gallons produced on the week- up from 308 million the week before and 295 million the same week last year. With the higher ethanol production and lower gasoline demand- ethanol stocks increased just slightly on the week indicating a solid week of ethanol exports.
  • Grain crushed for ethanol through February now totals 2,714 million bushels- up 166 million bushels over the same period last year.
  • USDA’s planting intentions report indicated US producers will plant just over 90 million acres of corn in 2024- down 1.8 million acres from analyst expectations ahead of the report. Soybean acreage of 86.510 compared to 86.530 million in expectations. Principal crop acres were down 6.3 million acres. Grain stocks all increased year over year but were as expected.
  • Open interest of Chicago futures and options positions increased for Chicago corn (0.9%), soybeans (2.8%), Soybean oil (0.3%), and cotton (0.7%) while falling for wheats (-1.5%), soybean meal (-0.9%) and rough rice (-6%).

With strong exports the corn deficit remained unchanged at 22 million bushels.
  • The First Crop Progress report of the year showed US corn planted at 2%- the same as last year. Cotton planted at 3% comparted to 4% last year.
  • The initial winter wheat conditions score of 348 compares to 279 last year and a 3-year average of 313. (500 is a perfect score).

OSU Deoxynivalenol, DON, Resistance Screening Program-2024

This past year, with support from Ohio Corn and Wheat through the Corn Check Off, we established a pilot corn deoxynivalenol (DON) hybrid susceptibility screening trial. The objective of this project was to identify hybrids with partial genetic resistance to DON. Use these results with caution because this is our first year of data. This trial was conducted at three locations across the state that represent different production regions:  Apple Creek, Bucyrus, and South Charleston. While we had three different environments, the fact that the hybrids vary in maturity means that there is a chance that the weather was not conducive to ear infection and DON production by the fungus Fusarium graminearum during each individual hybrid pollination window. All locations had natural infection across all maturity groups, but to help increase the change of Gibberella ear rot (GER) development, and consequently, DON contamination of grain, we also inoculated plots at Bucyrus and Apple Creek. Since average DON contamination was not significantly different between inoculated and naturally infected plots at these two locations, the results are summarized, and hybrids are compared, by location. With a relative maturity spread of 18 RM, the pollination window at all 3 sites was 3 weeks from the time the first silks emerged until only brown silks were found.

We have been researching several management strategies to reduce grain contamination with this mycotoxin, but less emphasis has been placed on genetic resistance. Results from our previous work with a very small number of hybrids showed that partially resistant hybrids with naturally and consistently lower DON levels are easier to keep low than those that were highly susceptible. A total of 80 hybrids from 8 seed companies were included as part of this screening. While this is only a small subset of the hybrids that are planted in Ohio, the results below not only show the importance of hybrid selection but also can be used to help you begin to select hybrids with natural partial resistance to DON, or at the very minimum, avoid highly susceptible hybrids. With one year of data, we cannot guarantee that the hybrids with low DON this year will always have low DON across all environments. The only thing we can guarantee is that the high-DON hybrids are susceptible. This is an excellent place to start.

Winter application of manure in Ohio: what’s allowed?

Last week’s snow was a reminder that we’re still in the middle of winter in Ohio, with more cold weather yet to come.  Winter weather is a challenge for those who handle manure, and it’s equally challenging to know the laws for applying manure on frozen and snow covered ground.  Those laws vary according to several important factors:  whether ground is frozen or snow covered, whether a farm is operating under a permit, and the geographical location of the land application.  Here’s a summary of the different winter application rules and standards in effect this winter.

What is frozen ground?  Ohio’s rules don’t define the term frozen ground, but generally, ground is considered frozen if you cannot inject manure into it or cannot conduct tillage within 24 hours to incorporate the manure into the soil.

Farms with Permits.  Farms with permits from the Ohio Department of Agriculture (ODA) or Ohio EPA operate under different rules than other manure applications in Ohio, and they cannot apply manure in the winter unless it is an extreme emergency.  Movement to other suitable storage is usually the selected alternative.  Several commercial manure applicators have established manure storage ponds in recent years to help address this issue.

New Independent Contractor Rule Coming Soon!

By: Jeffrey K. Lewis, OSU Extension

The U.S. Department of Labor (“DOL”) has introduced a new independent contractor rule, aiming to provide clarity and guidance for both employers and workers. The classification of workers as employees or independent contractors has become increasingly complex in recent years, resembling an endless carousel ride for many businesses, particularly those in the agricultural sector that frequently hire part-time and seasonal help. The DOL’s new rule, published under the Fair Labor Standards Act of 1938 (“FLSA”), seeks to put an end to this perpetual uncertainty surrounding worker classification once and for all.

Background
The FLSA establishes federal standards for overtime pay, minimum wage, and child labor. Ohio law explicitly aligns its interpretation of the term “employee” with that of the FLSA for wage and hour purposes. For the FLSA to apply to an agricultural employer, an employment relationship must be established. This entails determining whether a worker is classified as an employee or an independent contractor.

However, the FLSA itself is silent on how to exactly distinguish an independent contractor from an employee. So, for years the DOL relied on the court system to develop the standard for determining whether a worker should be classified as an employee or an independent contractor. The court system developed an “economic realities test” to help determine whether an employment relationship exists with a worker. The economic realities test is a totality of the circumstances test – which means all factors should be weighed evenly – and relies on six factors. These factors are:

  1. The nature and degree of control over the work;
  2. The individual’s opportunity for profit or loss;
  3. The permanency of the work relationship;
  4. Whether the work being performed is an integral part of the Employer’s business;
  5. The worker’s investment in facilities and equipment; and
  6. Skill and initiative.

For decades courts and the DOL have applied these factors, or a similar variation of them, to help define employee and independent contractor under the FLSA. However, courts across the country have applied the factors inconsistently and have given certain factors different degrees of weight.

Suspected 2,4-D Resistant Waterhemp Population Discovered

Source:  ICM News, Iowa State University

We know the evolution of resistance in waterhemp populations happens faster than new herbicides are discovered, so the recent report of dicamba resistant waterhemp in Iowa by Bayer was not unexpected. Corteva has now reported the discovery of a suspected 2,4-D resistant waterhemp population in Iowa. These reports emphasize the need to use herbicides wisely and diversify weed management tactics beyond herbicides, especially as more farmers rely on herbicide group (HG) 4-based postemergence weed control in both corn and soybean.

The particulars

In late January 2024, Corteva reported the discovery of a suspected 2,4-D resistant waterhemp population in 2022 in Wright County, Iowa. A Corteva employee collected two samples of waterhemp seed, one from plants in the field and one from plants growing in the ditch adjacent to the field. While greenhouse testing with seed collected from plants in the field did not confirm resistance, plants grown from the ditch population are suspected to be 2,4-D resistant. The communication reported that the ditch had a multi-year history of 2,4-D application to manage broadleaf weeds. Corteva will continue evaluation of the populations in the greenhouse and the field. If resistance is confirmed in this population, it will become at least the fourth report of 2,4-D resistance in waterhemp, joining prior reports from Nebraska in 2009 (Bernards et al. 2012), Illinois in 2016 (Evans et al. 2019), and Missouri in 2018 (Shergill et al. 2018).

Iowa State University screened populations of waterhemp against several herbicides in 2019 at their 1X rates (Table 1). On average, waterhemp exhibited 17% survival to 2,4-D, 5% survival to dicamba, and 4% survival to glufosinate (Hamberg et al. 2023). We are rapidly losing herbicide options for postemergence control of waterhemp.

Best management practices to slow resistance development

Now is the time to evaluate how to improve weed management in fields. While herbicides will remain the primary tactic to manage weeds, farmers can implement several best management practices to slow herbicide resistance evolution and improve control of weeds like waterhemp.

  1. Choose an effective herbicide program for the weed spectrum present on a field-by-field basis.
    1. Use full rates of effective residual herbicides and plant into a weed-free seedbed.
    2. Include overlapping residual herbicides and multiple effective herbicide groups in postemergence applications to provide longer waterhemp control. Consult manufacturers for specific tank-mix recommendations.
    3. Make timely applications and choose appropriate adjuvants, nozzles, application volume, etc.
    4. Scout fields 7-10 days after postemergence herbicide applications to evaluate weed control.
  2. Use a diversity of weed management tactics, including chemical, mechanical, and cultural options. Narrow row spacing, cover crops, more diverse crop rotations, and tillage are effective tactics to suppress waterhemp.
  3. Control weed escapes prior to seed production to reduce future weed populations and prevent resistance from spreading.
  4. Reduce influx of weed seed into crop fields by managing weeds in field edges and cleaning equipment between movement from problematic fields to clean fields. The detection reported here indicates the threat of weeds in field edges.
