Announcement for a Pesticide Risk Reduction Education Short Course on Oʻahu, October 16 - 17, 2018

Posted July 30, 2018


Pearl City (zip code 96782) on Oʻahu


October 16 - 17, 2018. 8:15 AM - 4:00 PM each day.


This in-depth two-day short course is about handling pesticides, including herbicides, in ways that will reduce risks to people and our environment. It will be conducted by an instructor from the College of Tropical Agriculture and Human Resources, University of Hawaiʻi at Mānoa. The course does not include the exam for restricted use pesticide certification. (If you want to take one of the certification exams offered by the Hawaiʻi Department of Agriculture, read the note “EXAMS FOR CERTIFICATION” near the bottom of this page.)


The course would benefit people who want to be better informed about handling pesticides properly or prepare for the Hawaii Department of Agriculture’s examination for restricted use pesticide certification.

Certified applicators will not earn re-certification credits by attending this course.


The instructor will discuss the topics covered by the study guides in the basic or “core” study packet, which provide general information common to all categories of certification exams. Certain topics such as identification and life cycles of specific pests and specialized equipment and calculations are covered only by the study guides in “category-specific” study packets, not in the short course. So if you plan to take a certification exam, you should also study the “category-specific” study guides, such as those in the “Private 1,2,3” study packet, the “Commercial 2 Forest pest control” study packet, or the “Commercial 7a,b,c,d,e pest control” study packet. (The complete list of categories of study packets is at

The basic or “core” topics to be covered in the short course include:

  • Types & formulations of pesticides
  • Laws & regulations about buying, storing, transporting, applying, and disposing of pesticides
  • Importance of a pesticide product’s labeling and safety data sheet (SDS).
  • Integrated pest management (IPM) concepts and components.
  • Common pests’ general identification features & life cycles
  • Application methods
  • Main parts of common spraying equipment
  • Dilution and dosage instructions on pesticide labels
  • Calculating sizes of treatment sites
  • Pesticides in the environment
  • Hazards to pesticide handlers
  • Protective clothing & safety equipment
  • Mixing, loading, application, transport, storage, and disposal
  • Washing work clothing
  • First aid for pesticide exposure


Deadline for registration is September 18, 2018. Enrollment is limited to 20 people.

If you have a disability and may need accommodations to participate, contact the UH Agricultural Diagnostic Service Center (in Honolulu), 808-956-6706, by September 18, 2018.

Test takers must make an appointment to take the exam to qualify for certification to buy or use restricted use pesticides in Hawaii. The Hawaii Department of Agriculture’s employees will sign up a test taker for a specific location, date and time. The exam fee is $25. (This fee is not included in the $100 fee for the short course.) Read more about the exams at


For a free copy of the booklet, “Test Your Math Skills,” contact the instructor or download it HERE. The leaflet presents exercises and answers that will help trainees refresh basic math skills needed to understand the instructor’s calculation examples. Trainees who find the exercises difficult will get more benefit from the short course if they get tutoring before the course begins. The exercises review (1) common fractions and their decimal number equivalents, (2) rounding-off, (3) percent, (4) conversions between • seconds and minutes • ounces and pounds • fluid ounces, pints, and gallons • square feet and acres, (5) reading tables, and (6) calculating square feet of rectangular areas. Test-takers must have these skills to answer some of the questions in the certification exams.

You can download another free leaflet, Practice Analyzing an Insecticide Label, HERE. Study the examples to boost your pesticide label reading skills, which you will need to plan a pesticide treatment or to prepare for the Hawaii Department of Agriculture’s restricted use pesticide certification exam.
