Sensitive Crops & DriftWatch

Kansas growers of sensitive and organic crops are increasingly concerned about drift damage from commonly used pesticides. To help reduce the risk of pesticide drift damage, the Kansas Department of Agriculture has become a partner state of DriftWatch Inc. DriftWatch Inc. is an online service that provides a place for producers of pesticide-sensitive specialty crops to map their crop locations. Pesticide applicators can use the website to find sensitive-crop locations in an effort to minimize the potential for damaging pesticide drift. Pesticide applicators can use the registry to identify where extra care should be taken to protect these vulnerable crops.

To register your sensitive crops grown in Kansas, visit https://driftwatch.org/.

If you suspect that a pesticide has been misused, including herbicide drift, report it to the Department of Agriculture immediately to 785-564-6688.

Kansas producers and applicators may now map their fields, and register for notifications by signing up at https://driftwatch.org/. This program will be replacing the former Sensitive Crop map.

Applicators can also learn how these new tools can be used to identify sensitive crops before applying pesticides.

The webinar, presented on Thursday, March 27 by FieldWatch, will be posted for those who were unable to participate the week of March 31. 

Please direct questions to Logan Brown, Kansas DriftWatch Data Steward, 785-564-6688.

Commercial Sensitive Crops

To register your sensitive crop on the new DriftWatch website, we recommend the following criteria be met:

  • The crop is grown for commercial purposes and represents a legitimate source of income for the grower
  • The crop is known for its propensity to be economically damaged by herbicides that volatilize readily
  • If it is an organic crop, it must be produced under an organic certification program
  • The producer requests that we publicize the location on the website

All approved crop sites appear on the DriftWatch registry map and is submitted directly to partner applicators. Farmers are responsible for keeping their information current and for removing a site that no longer meets these criteria. 

Registered DriftWatch Producers can purchase official 'No Drift Zone' signs to be posted in their fields. Order instructions will be sent once your specialty crop site is approved by the state data steward.

Also, 'Sensitive Crop Grown Here' signs  to post around your sensitive crop fields can be purchased through the K-State Research and Extension bookstore for $21.10 per sign

Current Sensitive Crop Map

The Sensitive Crop Map allows individuals to find the location of Sensitive Crops registered with the KDA. These crops include, but are not limited to, grapes, tomatoes, and cotton. To improve usage of the map please access the Sensitive Crop Map Instructions and Tips for Usage.

Hormone Type Herbicides

Kansas growers of sensitive and organic crops are increasingly concerned about drift damage from commonly used herbicides. Many crops, like grapes, cotton, tomatoes, and fruit and nut trees, are especially sensitive to hormone-type herbicides. Growers of organic crops can lose their USDA certification if any type of pesticide, including any insecticide or fungicide, is detected in their crops.

Hormone-type herbicides are used to control weeds, trees and brush on cropland, pastures, lawns and roadside rights-of-way. These herbicides can be prone to drift and to damage crops sensitive to them. The damage can be relatively minor, or it can cause total crop loss. Many factors will influence whether an herbicide moves off target, including temperature and wind, but correctly using the right equipment and making the application at the right time can reduce the likelihood.

The following list will help you determine if what you are using is a hormone-type herbicide. The trade names that appear in this list were chosen because they are commonly found in the marketplace. Similar products are sold under different trade names, so please check the ingredient list to verify whether the product you are using is a hormone-type herbicide.
