Crop Protection


Professional, precise pesticide application is the primary purpose of our business. We treat your fields as if they were our own.

The Thrush At Work

We work hard to provide competitive pricing and top-notch service.

Most customers prefer to contact us by telephone--785-332-2251--or by coming by our office. Texts and emails can work well, as long as we know what crops adjoin the target crop.

If you have questions about which products to use, we are happy to help you with the decision. We sometimes suggest alternative options which are less expensive or reduce cropping restrictions.

Because mineral-laden hard water can reduce pesticide effectiveness, we take the extra step of making all of our applications with soft water.

Agricultural News


Our home page has news and information about agriculture and events in the tri-state region, as well as what crops Grace Flying Service is currently treating.



Local Weather Stations


Local, internet-connected weather stations provide a wealth of valuable data: temperature, wind, humidity, rainfall totals, barometric pressure--and often maximums and minimums.

Current Broadview Weather

We operate two weather stations: Broadview and kSYF.

Our Broadview station is about 10 miles northeast of town, and the kSYF station is atop our office on the Cheyenne County airport in Saint Francis, Kansas.

Clicking the links above will give you a constantly updated summary of current weather. For a more detailed analysis, you can use the Davis Instruments WeatherLink 2.0 app on your desktop by clicking this link.

Herbicide Information


Kansas State University issues an excellent compendium of herbicides and weeds, entitled 2019 Chemical Weed Control for Field Crops, Pastures, Rangeland, and Noncropland. This 144 page document has everything from REIs, recommendations concerning which weeds are best controlled with different products, toxicity ratings, pesticide handling tips, soil persistence of herbicides, trade names of common pre-mixes, and more.

If you handle or apply herbicides, you will likely find this KSU publication useful. Click here for the newest KSU weed control guide.



REIs-Return Entry Intervals


Most pesticides have labeled limitations defining how soon you may re-enter the treated area. There are several exemptions to this REI rule--for crop advisers, hired handlers, and owners and their fam

Here are more details on the owner and family exemptions to re-entry.


As part of our custom application service we text Application Notifications to our customers when the field is treated. Our Application Notifications include the most restrictive REI for the tank mix that we applied.

If you would like to determine the REI of other products, this website is very useful.



Pesticide Labels


Finding pesticide labels on-line is occasionally difficult. You can click here for a pesticide label database from the EPA.

If that doesn't work, this link provides some helpful guidance. Often, we find that searching the product manufacturer's website is the fastest way.



Worker Protection Standard


The federal government issues WPS regulations designed to protect agricultural workers. These regulations affect all pesticide handlers and their employers, as well as anyone who might be in a treated field. There are several exemptions to the WPS rules--for crop advisers, hired handlers, and owners and their family.

The EPA revised the WPS regulations in November, 2015, and those new regulations went into effect January, 2017. In addition, three more regulations became effective January 2, 2018.
