Grower Survey to Assess Herbicide Drift Damage in the North Central U.S.

A special project group of the North Central Integrated Pest Management (IPM) Center wants to learn about your concerns and experiences with herbicide drift. The group is surveying growers of fruits, vegetables, and other specialty crops in the upper Midwest.

To truly understand the frequency, severity, and economic impact of herbicide drift on specialty crops, we need to hear from growers: growers who have experienced drift damage, growers who can share their concerns around this issue, and even growers who have not dealt with drift but who grow sensitive crops in drift-prone regions. Survey responses are needed to establish herbicide drift as a serious economic and regulatory concern in Ohio and across our region.

Please complete the survey at

Who should take this survey?

The study is for commercial growers of fruits, vegetables, and other specialty crops in IA, IL, IN, KS, MI, MN, MO, ND, NE, OH, SD, or WI. Even if you have never experienced herbicide damage, we would still like to hear from you if you grow specialty crops in one of these states.

Why is this survey necessary?

Dicamba and 2,4-D drift damage has made headlines in recent years, but no study to-date has attempted to quantify the overall impact drift has on the specialty crop industry. While all states have a way for growers to file a drift complaint, the process and requirements are inconsistent and may involve time and information that a grower does not have. In most states, for instance, the source of the drift must be identified. Research has found that dicamba and 2,4-D both have the potential to travel for miles in specific weather conditions, making source identification difficult.

What good will this survey do?

This study is designed to assess the potential and actual frequency of drift damage, along with the severity and economic impact of such damage. The survey includes questions on grower awareness, experience, actions, and decisions related to herbicide drift and drift-risk management. The responses will help establish needs for research on drift mechanisms, prevention, and remediation; and/or the need to review current policy and reporting requirements.

How long will it take?

The survey takes 5-20 minutes to complete, depending on your experience with drift damage.

How will this data be shared?

Summarized survey data will be shared broadly with regulatory agencies, university educators and researchers, agricultural policy makers, grower support organizations, and the general public using news articles, report summaries, and peer-reviewed journal articles. While this study is administered by The Ohio State University, it was planned in partnership with industry experts across the region who will assist with sharing results. Participants may also request a copy of the study summary.

How will my data be used and protected?

Your privacy is important. No individual survey data will be released or shared beyond the limited group of project staff. The survey questions and procedures have been reviewed by the institutional review board at The Ohio State University and are designed to protect your data and identity. Additional details on privacy and confidentiality are provided at the beginning of the survey.

How can I learn more?

The North Central IPM Center’s special project group created a series of fact sheets on herbicide drift especially for specialty crop growers. The series includes: Overview of Dicamba and 2,4-D Drift Issues, Frequently Asked Questions, Preparing for Drift Damage, and Responding to Drift Damage. Fact sheets and more information about our special project group and study are available at

This study is facilitated by The Ohio State University and is funded by the USDA National Institute of Food and Agriculture through agreement 2018-70006-28884.This study is being conducted in cooperation with regional universities and non-profit grower organizations, including Ohio State Extension.

You probably noticed that in 2020 we did not publish an updated Midwest Fruit Pest Management Guide (although updates were added to the on-line version). This was because the Midwest Fruit IPM Working Group spent 2020 working on a new format for the guide. The new format is driven by a database and will allow the group to develop a mobile-friendly version of the guide. The printed copy of the guide will continue to be revised every other year, with critical updates/corrections made in real-time to the on-line version of the guide.

For the 2021-2022 publication changes were made to the apple and grape sections only. The new format provides users  with same  information  as previous guides but is more concise and in our opinion easier to understand. Over the next two years we will transition the other crops in the guide to this format.

The grape and apple sections now include charts displaying pest emergence by stage and tables that incorporate product efficacy, REI, and PHI into the spray charts. The new charts (Figure 1) allow users to make side by side comparisons of products for efficacy and target pests throughout the crop season! Instructions on how to make the most of the new charts are also included.

Figure 1. Example of the new chart format in the Midwest Fruit Pest management Guide that allow users to make side by side comparisons of products for efficacy and target pests. Table layout and database development was supported by the USDA National Institute of Food and Agriculture, Crop Protection and Pest Management Program through the North Central IPM Center (2018-70006-28883).

We welcome your comments, criticisms and suggestions on the newly formatted apple and grape sections. A short on-line survey has been set up to collect your feedback. Even if you don't grow apples or grapes, we appreciate your feedback to improve the new layout design and its usefulness and effectiveness. The new layout for apple and grape will be applied to the remaining crops in the 2022 guide.

You can access the survey by scanning the QR Code below or you can click here. If you don’t have access to the internet and want to give us your feedback you can call an OSU Extension Specialist or your county Extension office. We will record and submit your feedback.

As with all pesticide spray guides, the recommendations for product usage (i.e., rate, PHI, REI, number of applications) are based on information provided in the product label. Remember, the label is the law!
