What Every Texas Rancher Needs to Know About Pesticide Safety
Pesticides are essential tools for Texas ranchers, controlling weeds, insects, and diseases that threaten pastures, crops, and livestock. But these same chemicals that protect your operation can harm you, your family, and your workers if they're not handled properly. Every year, agricultural workers experience thousands of pesticide-related illnesses, many of which are preventable with proper knowledge and precautions.
This guide covers the fundamental principles of pesticide safety that every Texas rancher needs to know.
Pesticide Toxicity
Types of Pesticides
- Herbicides: Kill or control weeds and unwanted plants
- Insecticides: Control insects
- Fungicides: Control fungal diseases
- Rodenticides: Control rodents
- Acaricides: Control mites and ticks
Toxicity Classifications
| Signal Word | Toxicity Level | What It Means |
|---|---|---|
| DANGER | Highly toxic | Can kill or seriously injure with small amount |
| WARNING | Moderately toxic | Can cause moderate injury |
| CAUTION | Low toxicity | Can cause slight injury |
Routes of Exposure
- Dermal (skin absorption)
- Hands and forearms are most often exposed
- Cuts and abrasions increase absorption
- Warm, sweaty skin absorbs more
- Inhalation (breathing)
- Spray mists, dusts, vapors
- Risk increases in enclosed spaces
- Temperature affects vaporization
- Oral (swallowing)
- Contaminated food or water
- Hand-to-mouth transfer
- Improper container storage
- Ocular (eyes)
- Splashes during mixing
- Drift during application
- Contaminated hands touching eyes
The Label is the Law
Legal Requirements
Using a pesticide contrary to its label is a violation of federal law. Label directions are minimum requirements, violations can result in fines and penalties, and liability for misuse falls on the applicator.
Label Sections
| Section | What It Tells You |
|---|---|
| Product name | Brand and common name |
| Active ingredients | What kills the pest |
| Signal word | Toxicity level |
| Precautionary statements | How to avoid harm |
| First aid | What to do if exposed |
| PPE requirements | What protection to wear |
| Environmental hazards | Protect water, wildlife |
| Directions for use | How to apply properly |
| Storage and disposal | Safe handling post-use |
Reading the Label
Before every application, work through these steps: identify the signal word, understand precautionary statements, note required PPE, check restrictions (weather, timing), and know the first aid procedures.
Personal Protective Equipment (PPE)
Minimum PPE Requirements
At a minimum, most pesticide labels require long-sleeved shirt and long pants, chemical-resistant gloves, shoes plus socks, and eye protection when specified.
PPE Selection Guide
| Glove Material | Best For | Common Use |
|---|---|---|
| Nitrile | Most chemicals | General use |
| Neoprene | Petroleum-based | Oil-based formulations |
| Butyl rubber | Gases, vapors | Fumigants |
| Natural rubber | Water-based | Limited protection |
For eye protection, goggles provide better protection from mists than safety glasses, and a face shield combined with goggles is appropriate for high-hazard applications.
Respiratory protection ranges from half-face respirators (required for many applications) to full-face models. The respirator must have the appropriate cartridge for the chemical type, and it must be properly fitted. Facial hair prevents a proper seal.
PPE Care
Remove PPE in reverse order of donning, wash contaminated clothing separately from family laundry, inspect PPE regularly for damage, and replace worn or damaged items promptly.
Safe Handling Procedures
Before Application
- Read the label completely
- Check weather (wind, rain, temperature)
- Gather all PPE and equipment
- Calculate correct amounts needed
- Ensure proper equipment calibration
- Know your application area boundaries
- Notify family/workers of application plan
During Mixing and Loading
This is the most dangerous phase of any pesticide application, because concentrated product means the highest exposure risk. Wear ALL required PPE. Keep containers below eye level, add pesticide to water (not water to pesticide), use measuring devices only for chemicals, never eat, drink, or smoke, clean spills immediately, and triple-rinse empty containers.
During Application
Avoid walking through treated areas, don't spray into the wind, keep nozzles at proper height, and don't touch your face or adjust PPE with contaminated gloves. Take breaks in a clean area away from treated zones. Check weather conditions throughout: don't apply before rain, observe wind speed limits, and avoid drift to non-target areas.
After Application
Clean all equipment thoroughly, remove PPE carefully, shower and change clothes, and wash work clothes separately. Record application details including any incidents or concerns. Texas requires some record-keeping for pesticide applications.
Storage Requirements
Storage Location
A proper pesticide storage area is well-ventilated, away from living spaces, away from food, feed, and seed, away from water sources, protected from temperature extremes, and fire-resistant if possible. Never store pesticides near children's access areas, in unmarked containers, in food containers, or where flooding can occur.
Storage Practices
Keep labels intact and readable, separate herbicides from insecticides to prevent cross-contamination, store dry formulations above liquids, and rotate stock so older products get used first. Replace deteriorating containers before they leak, and clean up any spills immediately.
Emergency Response
Exposure Response
Skin exposure: Remove contaminated clothing, wash the area with soap and water for 15 or more minutes, don't scrub (it may increase absorption), and seek medical attention for concentrated products.
Eye exposure: Hold eyes open and rinse for 15 or more minutes, seek medical attention, and bring the label to the doctor.
Inhalation: Move the victim to fresh air. If they're not breathing, begin CPR. Seek medical attention and bring the label.
Ingestion: Do NOT induce vomiting unless directed by medical personnel. Seek medical attention immediately and bring the container or label.
Medical Care
When calling for help, be ready with the active ingredient name, the exposure route and estimated amount, and the time since exposure. Have someone stay with the victim, begin first aid per the label's instructions, and don't become a second victim by entering a contaminated area without protection.
Spill Response
Spill Kit Contents
- Absorbent material (cat litter, vermiculite)
- Shovel
- Broom and dust pan
- Plastic bags
- Rubber gloves
- Safety glasses
- Emergency contact numbers
Spill Response Steps
- Protect yourself - Don PPE before responding
- Stop the source - Upright containers, stop leaks
- Contain - Prevent spread, protect drains/water
- Absorb - Use absorbent material
- Collect - Sweep up, bag contaminated material
- Dispose - Follow label disposal directions
- Decontaminate - Clean area thoroughly
- Document - Record incident
Reportable Spills
Large quantity releases and off-target drift causing damage must be reported to the Texas Commission on Environmental Quality (TCEQ).
Texas-Specific Requirements
Licensing
Private Applicator License is required for restricted-use pesticides on your own property. You must pass an exam administered by the Texas Department of Agriculture, and recertification is required periodically.
Commercial Applicator License involves different categories based on application type and carries more stringent requirements.
Record-Keeping
Restricted-use pesticide applications require records that include date, product, amount, location, and target pest. Good records for all applications help track effectiveness and are required for some certifications.
Worker Protection Standard
If you have agricultural employees, the WPS requires training, notification of applications, PPE provision, and decontamination supplies. These are federal requirements enforced in Texas.
Bottom Line
The label is the law, so read it completely before every use. Signal words tell you the toxicity level at a glance, and DANGER means you're dealing with a serious hazard. Skin absorption is the most common route of exposure, which makes gloves and long sleeves non-negotiable. Always use at least the PPE the label requires, and feel free to use more.
Mixing and loading is the highest-risk part of any application because you're handling concentrated product. Store pesticides in a locked, ventilated area away from living spaces. Know what to do in an emergency before it happens (Poison Control is 1-800-222-1222). Keep records of every application, because it's required for some products and smart for all of them. Get your license before using restricted-use pesticides, and always protect the people around you by notifying family, safeguarding water sources, and preventing drift.
