Pre-marking serves as a visual aid.  The bucket used to measure water is marked for 1, 2, and 3 gallons. These were common volumes used to mix pesticides at a greenhouse.

A manager thought of this idea when he had difficulty explaining gallon measurements to a handler who only knew the metric system. Instructing the handler to fill to a specific mark improved communications and reduced measurement error. 


setup iconSetup & use

  • Clearly mark desired volume using permanent black marking pens 
  • Label each container that will be used only for specific agricultural products. For example, one container will be only for pesticides or only for herbicides use. 
  • Decontaminate measuring containers after each use. 
  • Check and replace markings before they wear off.

For accurate measure of dry products, weigh each batch separately. Do not measure additional batches by filling a container up to a mark. Remember, the same volume may have a different weight depending on the size of the dry particles.


“Using these containers makes it easier to communicate with the pesticide handlers about the volumes (pesticides) to measure when mixing.”

  • Measuring pitchers (clear) 
  • Black permanent marker 


tips icon Tips

  • Use a 2-gallon measuring container for oils to minimize spills and lifting weight. 
  • Remember to mix pesticides in the proper order. 
  • Use a different measuring container for each product to prevent cross contamination. 
  • Provide handlers training on the United States Standard Units for liquids and weights.
