Free TX Pesticide Applicator Exam Flashcards

The state agency that administers pesticide applicator certification and enforces Texas pesticide rules. EPA sets federal standards, but TDA handles Texas certification details.

The Federal Insecticide, Fungicide, and Rodenticide Act. It governs pesticide registration, distribution, sale, and use, and makes label directions legally enforceable.

The locally supported passing score is 70%. Plan to meet that standard on both the core exam and any required category exam.

An applicator who applies pesticides for compensation or on another person's property. Commercial work generally requires the proper Texas certification category.

A person who applies restricted-use pesticides to land they own, rent, or operate, typically for agricultural production rather than for hire.

A person who applies restricted-use pesticides as part of a job but is not applying pesticides for hire, such as some government or institutional employees.

A pesticide EPA restricts because misuse may cause unreasonable adverse effects. RUPs may be purchased and used only by certified applicators or properly supervised users.

A pesticide that does not require certification for purchase or use. The user must still follow the label exactly.

A certified applicator remains responsible for the application, gives clear instructions, verifies label compliance, and is available for communication when supervising uncertified users.

Texas applicators must qualify in the category that matches the work performed, such as agricultural, aquatic, public health, or right-of-way pest control.

Texas renewal depends on applicator type. Local metadata lists 5 CEUs annually for commercial applicators and 15 CEUs per 5-year cycle for private applicators.

Records document what was applied, where, when, at what rate, by whom, and under what conditions. They must be retained and available for inspection.

Local practice content supports at least 2 years for restricted-use pesticide application records. Keep longer if a label, contract, or rule requires it.

Regulatory inspectors may review application records, storage areas, equipment, and application sites. Applicators should cooperate and produce required records.

Using a pesticide in a way that conflicts with its labeling is a violation of federal and state law. The label controls rates, sites, PPE, timing, and restrictions.

The label section that lists approved sites, target pests, rates, timing, methods, and restrictions. Check it before mixing or applying.

Shows that EPA has registered the product under FIFRA. It does not mean the product is harmless; it means it may be used when the label is followed.

Lists the chemical ingredients that control the pest and their percentages. Use it to compare products and avoid accidental duplication of active ingredients.

Indicates the highest acute toxicity category on pesticide labels. Products may also show POISON and the skull-and-crossbones symbol when highly toxic by oral, dermal, or inhalation routes.

Indicates moderate acute toxicity. Treat it as a serious hazard signal, not as a casual caution.

Indicates lower acute toxicity than DANGER or WARNING, but label directions and PPE requirements still apply fully.

The minimum time required between the last pesticide application and crop harvest. PHIs help keep residues within legal limits.

The time after application when entry into the treated area is restricted unless the person has required PPE and meets label or WPS exceptions.

EPA rules that protect agricultural workers and pesticide handlers through training, notification, PPE, decontamination supplies, emergency information, and entry restrictions.

Agricultural workers and handlers covered by WPS need pesticide safety training every 12 months.

WPS requires water, soap, and single-use towels close enough for workers or handlers to wash off pesticide exposure quickly.

The four main routes are dermal, oral, inhalation, and ocular. Dermal exposure is especially common during mixing, loading, and equipment handling.

Acute toxicity comes from one exposure or a short exposure period. Chronic toxicity develops from repeated or long-term exposure.

A toxicity measure: the dose that kills 50% of a test population. Lower LD50 values mean higher acute toxicity.

Wear at least the PPE listed on the label. More protective equipment may be used, but using less than the label requires is not acceptable.

Inspect gloves before use for tears, leaks, stiffness, swelling, or chemical damage. Damaged gloves can turn a handling task into direct dermal exposure.

Use the respirator type required by the label and conditions. SCBA provides supplied air for the highest-hazard atmospheres such as some fumigation or IDLH situations.

Begin flushing eyes immediately with clean running water and continue for at least 15 minutes. Seek medical help and provide the label or SDS.

Protect people first, stop the source if safe, contain the spill, follow label and SDS instructions, notify appropriate authorities when required, and prevent water contamination.

A hazard communication document with first aid, handling, storage, PPE, and emergency information. Keep it accessible where pesticides are stored or used.

The movement of pesticide droplets, particles, or vapor away from the target site. Drift can injure crops, contaminate water, expose people, and violate labels.

Smaller droplets drift more easily. Larger droplets, lower pressures, and drift-reduction nozzles generally reduce off-target movement.

A weather condition where cool air is trapped near the ground under warmer air. Inversions can keep pesticide droplets suspended and move them unpredictably.

A no-application area between the treatment site and sensitive areas such as water, homes, schools, or endangered species habitat. Follow the label's required distance.

Leaching occurs when pesticide moves downward with water through soil. Sandy soil, low organic matter, persistent chemicals, and shallow water tables raise the risk.

Mix and load on an impervious, contained surface away from wells, drains, and surface water when possible. Point-source spills are a major contamination risk.

When a label directs it, applicators must check EPA's county-specific endangered species limitations before applying and follow any enforceable restrictions.

Avoid applying bee-toxic pesticides when crops or weeds are blooming, follow label timing restrictions, reduce drift, and consider notifying nearby beekeepers.

A decision process that combines monitoring, thresholds, prevention, cultural, biological, physical, and chemical controls to manage pests with less unnecessary pesticide use.

The pest level where control action is justified to prevent economic injury. It helps avoid treating too early or too often.

Practices that delay pesticide resistance, such as rotating modes of action, using labeled rates, limiting repeated applications, and combining chemical and nonchemical controls.

The process of checking equipment output so the correct amount of pesticide is applied per unit area. Calibration prevents underdosing, overdosing, waste, and violations.

Nozzles should deliver consistent output across the boom. A badly worn, clogged, or mismatched nozzle can create streaks, crop injury, poor control, or overapplication.

Agitation keeps formulations such as wettable powders and flowables evenly suspended. Poor agitation can make the first and last acres receive different rates.

Apply leftover mixture to a labeled site at or below the label rate when allowed, or dispose according to label and regulations. Never dump it into drains, ditches, or water.
