Decoding Chemical Labels

FBN Network

The cardinal rule of ag chemicals: Always read the label.

Your best resource for learning how to use your product safely and effectively is the manufacturer. This helpful guide will help ensure that everyone on your operation has a safe and successful application.

Active Ingredient Statement

The Active Ingredient Statement provides the name and amount of each active ingredient and the total ratio of inert ingredients in the container.

  • The important chemical(s) are individually listed on the label by the common and/or chemical name and the concentration (as a percentage) in the product.
  • Liquid products generally show both the percentage of the active ingredient and the amount in the container. Since all liquid products don’t weigh the same, it is important to understand the pounds of active ingredient in each gallon.
  • Dry products usually only list the percentage of the active in the package. If the label says a product has 50% of an active ingredient, then you can multiply the percentage by 16 oz. to figure out the amount of active in the package.

 

Key Pests Controlled

The list of pests controlled by a given product should be listed under the brand name. This is often not the complete list of labeled crops or pests, so make sure you review the entire label and verify that the crop you plan to spray is identified.  Don’t rely on general terms of what the product will control. If you’re spraying for rootworm in corn, make sure the label specifically identifies the product’s use for Corn Rootworm.

 

EPA Registration Number and Establishment Number

The EPA Registration Number indicates the specific company who registered the chemical and and verifies that it has been approved for sale. The EPA Establishment Number Identifies the approved EPA facility where the product was manufactured.

 

What’s in the Container?

Commercial Name

The brand name given by the manufacturing company, for example, Roundup®.

 

Common Name

The name given by the EPA to a chemical for easier recognition. Glyphosate is the common name for Roundup®.

 

Chemical Name

The technical name that identifies the chemical components and structure. For example, N-(phosphonomethyl) glycine, or Glyphosate.

 

Inert Ingredients

These ingredients are not required to be individually listed, but the total inert concentration must be listed. Variations in inert ingredients can affect the performance of the active ingredient, so it’s important to talk with your local crop consultants, pest control advisors, and university extension agents to understand their effect on particular crops, soils, and pests.

 

Signal Words

Signal words indicate the relative acute toxicity of the product to humans and animals. If two products will control the same pest, signal words can help you choose the least toxic option.

There are 4 Types of Single words:

  1. DANGER ☠ POISON - Highly toxic by any route of entry into the body.
  2. DANGER - Can cause severe eye damage or skin irritation.
  3. WARNING - Moderately toxic either orally, dermally, or through inhalation; causes moderate eye or skin irritation.
  4. CAUTION - Slightly toxic either orally, dermally, or through inhalation; causes slight eye or skin irritation.

First Aid or Statement of Practical Treatment

Direction on what to do if someone is accidentally comes in contact or is poisoned by a pesticide. ALWAYS call the National Poison Center Hotline (1-800-222-1222) for further medical instructions.
