The Iowa Department of Agriculture and Land Stewardship has partnered with the non-profit company FieldWatch™, Inc., to provide online registry tools to promote communication between producers of pesticide-sensitive (i.e. specialty) crops, beekeepers and pesticide applicators.  An agreement with IDALS and FieldWatch™, Inc. was arrived at in 2016 with rollout of a new Iowa Sensitive Crops Registry using the FieldWatch™, Inc. platforms as of January of 2017.

These online FieldWatch™ registries support ongoing stewardship activities to reduce incidences of off-target pesticide exposure. The registries provide state of the art mapping features that provide applicators the locations of registered specialty sites. The boundaries on map entries are user-submitted specialty/sensitive site designations. In addition to site designations, the map interface provides other data layers, including one mile radius boundaries around apiaries. 

Two online registry tools developed and provided by FieldWatch™, Inc. are 1) driftwatch®: a registry site for use by producers of commercial crops sensitive to pesticides, and 2) beecheck®: a registry site for beekeepers and apiarists.  Specialty crop producers with apiaries may enter hive locations using either the driftwatch® or beecheck® registries.  Submitted producer site entries are overseen by state-appointed stewards prior to their inclusion in the online registries.

Specialty Crops

The intended crops for inclusion on the registries are the following:

 - Beehives/apiaries
 - The following crops (includes conventional and certified organic designations):
      - commercial vegetable plots (berries, fruits, pumpkins or melons, and vegetables)
      - commercial nursery crops
      - commercial vineyards (grapes)
      - commercial orchards
      - commercial evergreen/Christmas tree plantings

 - Certified organic row crops, small grains, and pasture
 - All commercial crops transitioning to certified organic
 - Certain corn and soybean crops, including non-GMO lines, that may be sensitive to some pesticides
 - The minimum field size for all specialty crop sites is ½ acre.

First Time User Instructions



The FieldWatch™, Inc. registries will help protect honey bees from exposure to chemicals that are toxic to bees.  Registered locations of beehives will enable applicators to locate and minimize exposure to applied pesticides.  Effective January 22, 2009, the Department adopted an amended “Pesticide/Bee Rule” of the Iowa Administrative Code Chapter 21-45.31(206).  The Rule reads:

“45.31(1) Owners of apiaries, in order to protect their bees from pesticide applications, shall register the location of their apiaries with the state apiarist.  Registration shall be on forms provided by the department.  The registration expires December 31 each year and may be renewed the following year.
45.31(2) Between 8 a.m. and 6 p.m., a commercial applicator shall not apply to blooming crops pesticides labeled as toxic to bees when the commercial applicator is located within one mile of a registered apiary.; A commercial applicator shall be responsible for maintaining the one-mile distance from apiaries that are registered and listed on the sensitive crop registry on the first day of each month.

This rule is intended to implement Iowa Code sections 206.6(5)”a”(3) and 206.19(2).”

This amendment effectively ends notification by applicators to beekeepers within the area, but limits and restricts the timing of applications within a one mile radius of the hives.    
Forms referred to in the “Pesticide/Bee Rule” can be provided as paper copies by contacting the Department.

Annual Registration

Registered producers and beekeepers may update their information at any time during the year.  However, because registration expires December 31st of each year, producers and beekeepers that wish to remain actively registered must confirm, and edit if necessary, their registration information beginning in January of the following year.


A third online registry tool, FieldCheck™ allows applicators increased access to producer data.  One free feature for registered applicators allows them to designate an entire state, counties within a state, or other free-drawn areas in which they will then receive automatic notices of any new entries.  An enhanced applicator feature allows for downloading files of producer entries including shapefiles, Excel, csv or live stream through a software provider.  This enhance feature requires a $100 per year fee, or agriculture retailers can join for $500 fee and $100 per location to give multiple applicators access to the downloadable files.  This fee is waived for some designated government entities.  More details can be found using the FieldCheck link.

A listing of deer and elk premise locations is provided so that the aerial application of pesticides, and/or plane turns near these locations can be avoided whenever possible. This listing is being provided in addition to the listings of specialty crops and apiaries.  Please use the link “Deer and Cervidae Listing” in the box to right on this page.
