✓ Florida-specific rules ✓ Calibration formulas with examples ✓ Updated October 2026

Exam Overview

What it is

The General Standards exam, usually called the Core exam, is the foundation test for Florida pesticide certification

Passing Score

70% or higher (per UF/IFAS Extension)

Administered By

Florida Department of Agriculture and Consumer Services (FDACS)

Fees & Registration

Set by FDACS and subject to change. Confirm current fees and testing options on the FDACS pesticide licensing pages

⚡ Important: Commercial and public applicators pass the Core exam plus an exam for each license category they want. Private applicators who use restricted-use pesticides on agricultural land take Core plus the Private Applicator Agricultural exam. This guide covers the Core exam.

⚖️

Section 1: Florida Laws & Regulations

Who regulates what

EPA registers pesticides and sets federal rules under FIFRA
FDACS licenses and certifies pesticide applicators and registers pesticides sold in Florida
Chapter 487, Florida Statutes is the Florida Pesticide Law; certification rules are in Chapter 5E-9, Florida Administrative Code
Structural pest control (termite and household pest companies) falls under a separate law, Chapter 482, and a separate FDACS bureau

Applicator types

Private applicator: uses restricted-use pesticides to produce an agricultural commodity on land they own, rent or are employed to work
Commercial applicator: applies pesticides for hire or as part of a business; certified by category
Public applicator: applies pesticides as an employee of a government agency

Restricted-use pesticides (RUPs)

Can be bought and used only by certified applicators, or by trained people working under a certified applicator's supervision
Classified as restricted because of risk to people, groundwater or wildlife
Federal rules require RUP application records, generally within 14 days of the application and kept for 2 years

Key legal ideas to memorize

Registered pesticides must carry an EPA registration number
Using a pesticide in a way not allowed by its label is a violation of law
You are responsible for drift, runoff and damage caused by your applications
Licenses expire and must be renewed, with continuing education, on the schedule FDACS sets

🏷️

Section 2: Label Reading & Interpretation

The label is the law

Do not exceed the labeled rate
Do not apply to sites or crops not listed on the label
Follow every restriction: buffers, wind limits, rainfast periods, intervals between applications
Federal law: it is a violation to use a product in a manner inconsistent with its labeling

Signal words

DANGER = Toxicity Category I (most toxic). Products that are highly toxic by mouth, skin or inhalation also say POISON with a skull and crossbones
WARNING = Category II (moderately toxic)
CAUTION = Categories III and IV (slightly toxic or relatively non-toxic)
Signal words describe acute toxicity of the product. They do not tell you how well it works or how long it lasts

Where to find what on a label

Front panel: brand name, ingredient statement, signal word, net contents, EPA registration number, restricted-use statement if it applies
Precautionary statements: hazards to people and animals, required PPE, environmental hazards
Statement of practical treatment: first aid
Directions for use: sites, pests, rates, timing, REI, PHI, application method
Storage and disposal: how to store, rinse and dispose of the product and container

Intervals that show up on every exam

REI (restricted-entry interval): how long workers must stay out of a treated area
PHI (pre-harvest interval): minimum days between the last application and harvest
Re-treatment interval: minimum time between applications of the same product

🦺

Section 3: Safety & PPE

How pesticides enter the body

Dermal (skin) is the most common route of exposure for applicators
Inhalation (lungs) is the fastest route and the most dangerous with vapors, fumes and fine dusts
Oral (swallowing) usually results from eating, drinking or smoking with contaminated hands, or from unlabeled containers
Ocular (eyes) absorbs quickly; eye protection is required whenever the label says so

Choosing PPE

The label tells you the minimum PPE; always wear at least what it requires
Use chemical-resistant gloves such as nitrile or butyl, not leather or cloth. Wear sleeves over glove cuffs when spraying overhead
Respirators must match the hazard (for example the right cartridge), fit properly, and be maintained
Wash PPE and clothing separately from household laundry; replace worn or contaminated items

Florida heat is a safety issue too

Heavy PPE in hot, humid weather raises the risk of heat illness
Schedule work for cooler hours, take breaks, drink water, and learn the signs of heat exhaustion and heat stroke

Poisoning and first aid

Organophosphates and carbamates inhibit cholinesterase; symptoms include drooling, sweating, tearing, muscle twitching and blurred vision
Call Poison Control: 1-800-222-1222 and have the product label ready
Skin: remove contaminated clothing, wash the skin with soap and water
Eyes: flush with clean running water for at least 15 minutes
Inhaled: move to fresh air immediately
Swallowed: follow the label; do not induce vomiting unless the label says to

🧪

Section 4: Pesticide Formulations & Application

Common formulations

EC (emulsifiable concentrate): oil-based liquid that forms a milky mixture in water; can be absorbed through skin and may damage some plants
WP (wettable powder): needs constant agitation; dust is an inhalation risk when mixing
WDG / DF (water-dispersible granule / dry flowable): lower dust than WP; measure by weight
F / FL (flowable): liquid suspension that needs agitation
G (granule): applied dry; no mixing and low drift
S / SL (solution): dissolves fully in water; no agitation needed

Adjuvants

Surfactants help spread and wet leaf surfaces
Stickers help the product stay on the target
Drift-control agents increase droplet size
Compatibility agents help products mix; do a jar test if you are unsure
Mixing order often follows the WALES memory aid: Wettable powders, Agitate, Liquid flowables, Emulsifiable concentrates, Surfactants. Label directions override any mnemonic

Calibration formulas

Acre = 43,560 square feet. Area in acres = length × width (ft) ÷ 43,560
Gallons per acre (GPA) = gallons sprayed ÷ acres covered
GPA from nozzle output = (GPM per nozzle × 5,940) ÷ (MPH × nozzle spacing in inches)
Acres per tank = tank size (gal) ÷ GPA
Product per tank = labeled rate per acre × acres per tank
Conversions: 1 gal = 4 qt = 8 pt = 128 fl oz

Worked examples

A field measures 300 ft × 400 ft: 120,000 sq ft ÷ 43,560 = about 2.75 acres
Sprayer output is 20 GPA with a 300-gal tank: 300 ÷ 20 = 15 acres per tank. At 2 qt of product per acre, add 30 qt per tank
You need 2 lb active ingredient (a.i.) per acre and the product is 4 lb a.i. per gallon: 2 ÷ 4 = 0.5 gal (2 qt) per acre

Reducing drift while you apply

Larger droplets drift less; match nozzle type and pressure to the label
Keep the boom low, and avoid spraying in strong wind or in calm, stable air (a temperature inversion)
Apply only when the label's wind and weather limits are met
Recalibrate whenever you change nozzles, pressure or speed, and check for worn nozzles

Section 5: Pest Management Principles

Integrated Pest Management (IPM)

A decision-based approach that uses several tactics to keep pests below damaging levels while limiting risk to people and the environment
Steps: identify the pest, monitor and scout, set action thresholds, choose controls, evaluate the results
Economic threshold: the pest level at which control costs less than the damage it would cause
Tactics: cultural (sanitation, crop rotation, resistant varieties), mechanical, biological (natural enemies), and chemical

Know your pest

Insects: incomplete metamorphosis (egg, nymph, adult) versus complete metamorphosis (egg, larva, pupa, adult); control timing depends on the stage
Weeds: annual, biennial or perennial; broadleaf, grass or sedge
Plant diseases: fungi, bacteria, viruses and nematodes; disease needs a host, a pathogen and a favorable environment
Correct identification comes first. A wrong ID leads to the wrong product and wasted money

Resistance management

Repeated use of the same mode of action selects for resistant pests
Rotate products with different modes of action and combine IPM tactics
Florida's warm climate allows many pest generations a year, which speeds resistance
Never use less than the labeled rate; sub-lethal doses speed resistance

Section 6: Environmental Protection (Florida Focus)

What happens to a pesticide after application

Drift: airborne movement off target during or after application
Runoff: movement across the soil surface in rain or irrigation water
Leaching: downward movement through soil toward groundwater
Volatilization: turning into a gas after application
Adsorption: binding to soil particles (clay and organic matter hold more than sand)
Degradation: breakdown by microbes, sunlight and chemical reactions. Persistence is how long a product remains active

Why groundwater matters so much in Florida

Much of the state has a shallow water table and sandy, fast-draining soils, which makes leaching more likely
Limestone geology in many areas connects surface water to groundwater and springs
Heavy summer rainfall raises runoff and leaching risk right after an application
Use extra care near wells, springs, sinkholes, canals, lakes and wetlands

Protecting water

Never mix or load next to wells or surface water; use a backflow-prevention device or air gap on the fill hose
Keep the label's buffers and setbacks from water bodies
Do not apply ahead of heavy rain
Rinse sprayers in the field and apply rinsate to a labeled site, not to drains or ditches

Protecting non-target organisms

Pollinators: avoid spraying plants in bloom while bees are foraging, and follow label bee-hazard statements
Aquatic life: many products are highly toxic to fish and invertebrates
Threatened and endangered species: check the label and any use-limitation bulletins for your area

Storage, spills and disposal

Store in the original labeled container, in a locked, ventilated area away from food, feed, water and living areas
Hurricane season: keep stored products above likely flood levels and away from wells
Spills: Control the source, Contain the spill, Clean up with absorbent material. Report spills as required
Triple-rinse or pressure-rinse empty containers, add the rinsate to the spray tank, and dispose of or recycle containers as the label directs
