The C&T credit course is intended to cover all missing topics (competency standards) from our study manuals and exams to help current licensees meet the updated federal requirements. These topics cover a broad range of information from Laws and Safety and several categories. 

The C&T credit course must cover all the listed topics to qualify for the credit. These topics are based on competency standards listed in the federal Certification of Pesticide Applicators Rule, 40 CFR 171.103 and 171.105.
Category Competency Standard (Topic)
Laws and Safety
  • Recognizing and understanding the difference between mandatory and advisory labeling language
  • Dilution procedures.
  • Methods of application used to apply various forms and formulations of pesticides.
  • Maintaining chemical security for restricted use pesticides.
  • How to communicate information about pesticide exposures and risks with customers and the public.
  • Appropriate product stewardship for certified applicators.
Demonstration and Research
  • Potential problems, pests, and population levels reasonably expected to occur in a demonstration situation.
  • Effects of pesticide use on target and non-target organisms.
Insect and Disease Control
  • Pre-harvest or restricted entry intervals and other entry-restricted periods and areas.
  • Potential for phytotoxicity, drift, persistence beyond the intended period of pest control, environmental contamination, non-target exposure, and other problems resulting from the use of pesticides.
  • Application methods to minimize hazards to humans, pets, other domestic animals, and non-target organisms.
Private Applicator
  • Understanding that applicators must comply with all use restrictions and directions for use contained in pesticide labels and labeling, including being certified in the correct category to use restricted use pesticides for fumigation or aerial application.
  • Understanding and complying with product-specific notification requirements.
  • Recognizing and understanding the difference between mandatory and advisory labeling language.
  • Providing use-specific instructions to noncertified applicators using restricted use pesticides under the direct supervision of a certified applicator.
  • Relative hazards associated with using pesticides on animals or places in which animals are confined based on formulation, application technique, age of animal, stress, and extent of treatment.
Soil Fumigation
  • Conducting pre-application inspection of application equipment.
  • Identifying pests causing the damage and verifying they can be controlled with soil fumigants.
  • Understanding the relationship between pest density and application rate.
  • Importance of proper application depth and timing.
Space (nonsoil) fumigation
  • Familiarity with the pesticide labels and labeling for products used to perform non-soil fumigation, including labeling requirements specific to non-soil fumigants.
  • Buffer zones, including procedures for buffer zone monitoring and who is permitted to be in a buffer zone.
  • First aid measures to take in the event of exposure to a fumigant.
  • Conducting pre-application inspection of application equipment and the site to be fumigated.
  • When a fumigant management plan is required, how long it must be kept on file, where it must be kept during application, and who must have access to it.
  • Elements of a fumigant management plan and resources available to assist the applicator in preparing a fumigant management plan.
  • Person responsible for verifying that a fumigant management plan is accurate.
  • Elements, purpose, and content of a post-application summary, who must prepare it, and when it must be completed.
Vertebrate Pest
  • Crops, grasslands, non-crop agricultural lands, ornamental plants, and turf and vertebate pests associated with those areas, including recognizing those pests and signs of their presence, habitats, life cycles, biology and behavior.
  • Potential for persistance of the pesticide beyond the intended period of pest control.
  • Application methods to minimize hazards to humans, pets, other domestic animals, and non-target organisms and to minimize runoff.
  • Comprehension of laws and regulations applicable to the control of vertebrate pests.
  • Types of environments traversed by rights-of-way.
  • Labels and labeling comprehension.
Weed Control
  • Pre-harvest or restricted entry intervals and other entry-restricted periods and areas.
  • Potential for phytotoxicity due to a wide variety of plants and pests that need to be controlled, drift, persistence beyond the intended pest control period, environmental contamination, non-target exposure, and other problems resulting from the use of pesticides to control weeds, including runoff, drift, and excessive destructive of foliage.
