What now? Using the Sports Field Management website for planning

“In winter, I plot and plan. In spring, I move.” – Henry Rollins

And for those responsible for maintaining athletic fields, we move a lot! And, of course, we want that movement to be effective, efficient, and within budget. The Sports Field Management website has field management schedules to help determine which turf management practices are most important now.

The first step in using these schedules is to determine what resources are available. This handy chart can help determine whether you have high, medium, or minimal management fields.

Field Management Type ChartOnce you have determined what type of field you are managing, and what seasons sports are being played on it, you can download a Seasonal Field Management  Schedule. For example:Sports Field Management Schedule-Spring Medium

Schedules are available for Spring only, Fall only, Spring and Fall, and Year-Round sports. Use them to help in communicating needs, establishing budgets, and planning activities.

 

Ground Bees Come in Peace

One of the first springtime insects that observed in school yards are ground bees. These insects create ant-hill like mounds in areas of bare soil with a ¼” opening in the center (about the thickness of a pencil). On warm, sunny days there may be dozens to hundreds of bees flying low to the ground among the mounds. Despite a general and perhaps debilitating fear of bees – the truth is that this species is relatively harmless and may not require any management. Here’s why:

 

  1. Ephemeral: ground-nesting bees are pollinators of early blooming flowers. Because their lifecycle is tied to the cycle of these plants, ground bees are only active for a short period of time in early spring.
  2. Solitary: fear of bees arises from the idea

    that disturbing a nest will provoke an entire colony of stinging insects. However, as it true of carpenter bees, cicada killer wasps, and mud dauber wasps, ground bees are solitary with only a single female bee per mound.

  3. Shy Gals: female bees make nests for the purpose of reproduction. After gathering nectar and pollen as food for their offspring, females will mate and lay eggs in the nest. While in the nest, females appear shy, and will retreat into the burrow if they see an approaching object.
  4. Males Hover, but Can’t Sting: All those bees you see flying low to the ground en masse – are males! And male bees do not possess a stinger. Their low, hovering flight is part of their effort to pair up with a female. Indeed, male ground bees are quite docile. See how one school responds to this insect with curiosity and affection in this video.

    Male ground bees cannot sting and are quite docile.

If you wish to discourage ground bees from taking up residence on your school grounds, an effective, safe and long-term solution is over-seeding with grass. By creating a dense lawn, bees will not be able to dig in the soil and will nest elsewhere. For information on creating a healthy lawn, see the Cornell Turfgrass Program.

 

Additional information about ground bees is available from the Cornell Department of Entomology.

Snow, Frost a Big Help for Head Start on Quality Turf

Want a two or three week head start on getting your athletic fields ready for spring? Consider a proven IPM practice: dormant overseeding.

Yes, right now those artic blasts might still be leaving us chilled. But winter weather has its advantages: snowmelt and freeze-thaw cycles can aid in both pushing and pulling seeds into the ground, maximizing seed-to-soil contact.

Meanwhile, spring is just around the corner — meaning it’s time to be on the lookout for weather conditions that allow you to apply grass seed.  So secure your seed and calibrate your spreaders.

What conditions are you looking for? Choose a time when:

  • there’s no snow cover
  • nighttime temperatures are predicted to dip below freezing and …
  • days warm to above freezing.

Ideally the forecast will also call for snow — snow that will push the seed into the ground while also protecting the seed from marauding birds. When that snow melts and is absorbed into the soil, it also helps pull your seed down through the crowns of existing plants, further increasing seed-to-soil contact.

Choose which seed to apply by your expectations for each field. Will your athletes be on the field in early spring? Then apply the quickly germinating perennial rye at a rate of 6 lbs./1000 ft2. If you have fields that won’t be used until June or July, apply Kentucky bluegrass at a rate of 3 to 4 lbs./1000 ft2. There will be some loss due to seed mortality, so these rates are 50% above conventional rates. If your budget is low, you can reduce costs by only overseeding on bare soil.

Your IPM benefits? Dormant seeding allows you to avoid cultivating the turf when the soil is too soft and wet to work. It saves fuel and equipment costs, too. And getting this turf management practice out of the way early means you’re better set up for the busy field season. Best of all, the seeds you apply in winter can germinate two to three week earlier than those applied during a conventional spring seeding — and your grass will be better able to face the onslaught of spring weeds and athletic cleats.

Child Safe Playing Fields Act – Frequently Asked Questions

A New York law essentially banning pesticide use on the grounds of schools and day care centers has been full effect since 2011. The letter of the law states:

A vacuum transforms into an effective IPM tool when used to collect yellow jackets entering and exiting subterranean nests.

A vacuum transforms into an effective IPM tool when used to collect yellow jackets entering and exiting a subterranean nests.

No school or day care shall apply pesticide to any playgrounds, turf, athletic or playing fields, except that an emergency application of a pesticide may be made as determined by the county health department or for a county not having a health department such authority as the county legislature shall designate, the commissioner of health or his or her designee, the commissioner of environmental conservation or his or her designee, or, in the case of a public school, the school board.

Questions about the law still abound. Here are the most common questions we receive:

What areas are affected?

Besides the playgrounds, turf, athletic or playing fields clearly stated in the law, playground equipment and fence lines around athletic fields and tennis courts are included.

The following areas are left to local discretion, but with the understanding that the intent of the law is to reduce children’s exposure to pesticides:

  • Areas around buildings
  • Ornamental plants such as trees, shrubs, and flowers

Pesticides used inside of schools or day care centers, or to protect a structure, are not banned.

Family day care centers are exempted.

What if a fence line is managed by the surrounding landowner (such as childcare center on a college campus)?

The inside of this child care center’s fenceline falls under the Child Safe Playing Fields Act.

The inside of this child care center ’s fenceline falls under the Child Safe Playing Fields Act.

The law applies to the interior fence line that encloses the play area (the side that children may contact).  The law would not apply to the exterior fence line.

If a park hosts school athletic events, such as games and practices, must it be managed under the law?

No.

What pesticides are banned and are there any exceptions?

Pesticides are substances intended to prevent, destroy, repel, or mitigate pests. They include insecticides, fungicides, herbicides, rodenticides, and plant growth regulators. All EPA registered pesticides are banned by this law for use on grounds at schools and day care centers, with the following exceptions:

  1. Antimicrobials such as bleach
  2. Aerosol sprays (18 ounce or less) to protect from imminent danger from stinging or biting insects
  3. Insect and rodent baits in non-volatile containers
  4. Products containing boric acid or disodium octaborate tetrahydrate
  5. Horticultural oils and soaps
  6. EPA exempt pesticides, known as minimum risk pesticides and 25(b) products, are not registered by EPA because they find them to pose little or no risk. Cornell has a list of allowable herbicides for schools and day care centers available for your reference.

Note that all of the above exceptions (except bleach) must be applied by a NYS licensed pesticide applicator. Any off label use of a product – such as the use of bleach, vinegar, road salt, or home remedies to control a pest – is illegal under state law.

Is there a provision within the law to add additional materials to the exempt list?

No. A change would require either the EPA to add to its 25B list or the NYS legislature to pass new legislation.

How do we apply for an emergency exemption?

Under the law, a public school can seek permission for an emergency application from their school board. Non-public schools and day care centers ask the Department of Health in the case of emergencies that threaten public health, such as ticks, or the Department of Environmental Conservation for those significantly affecting the environment, such as an invasive species.

While clover does not provide the traction and stability of turfgrass, it is considered a repetitive pest problem and not an emergency under the law.

While clover does not provide the traction and stability of turfgrass, it is considered a repetitive pest problem and not an emergency under the law.

While the law does not indicate what might be construed as an “emergency”, the Guidance document states pest issues are NOT emergencies if they are:

  • manageable with allowed products and practices
  • a routine or repetitive pest problem
  • purely an aesthetic issue

We are used to dealing with the DEC on pesticide issues. Besides deciding on emergency exemptions for environmental issues on private school and day care grounds, what is their role in the law?

The Department of Environmental Conservation, in consultation with the State Department of Education, State Department of Health, and the Office of Children and Family Services has written guidance for alternative management of turf, but has no role in enforcement.

Where can I find help in managing my grounds without the use of pesticides?

The new Cornell Sports Field Management website provides sports turf managers with the latest best management practices and resources they need to maintain safe and functional school and community sports fields.

Safe Sports Fields Management website

Are you struggling with bare spots, weeds, and grubs in your athletic fields? There is a new resource to help!

Safe Sports Fields ManagementThe Safe Sports Fields Management website brings you the latest best management practices for managing sports fields and resources for all who care for and use sports fields.

For the grounds manager, there is information on such topics as:

  • soils
  • grass varieties
  • routine care including assessing the field, mowing, fertilizing, overseeding, and more
  • pests
  • synthetic turf

The website goes beyond the basics, however. There are sections specifically for coaches and athletic directors, whose decisions can greatly impact the turfgrass quality and safety of the fields. Administrators are not left out, with their own page highlighting risk management. Not to be missed is the the video of Cornell Turfgrass Extension Specialist Frank Rossi’s presentation on Duty of Care.

Sports Field Management Schedule

General seasonal management schedules are available for high, medium, or minimal management fields serving spring, fall, spring and fall, or year round sports.

A highlight of the website is the inclusion of management schedules. These schedules, divided by field use and expectations, provide clear guidelines for the minimum management practices that must take place to maintain safe fields. The schedules can be used for not only for planning, budgeting, and scheduling, but are also valuable communication tools useful for justifying the need for resources.

The site was developed by the Cornell Turfgrass team with input from Cornell Cooperative Extension colleagues and sports turf grounds managers from across New York State. Funding was provided by the Community IPM Initiative of the New York State Integrated Pest Management Program to support New York State schools in implementing the Child Safe Fields Playing Act.
