Study Notes
Integrated Pest Management (IPM)
- IPM is a proactive pest population management system designed to prevent damage caused by pests.
- Implements ecological approaches including pest identification, monitoring, and biological controls.
Pesticide Regulations
- A pesticide, per law, is any substance aimed at preventing or mitigating pests, including growth regulators.
- Registration of pesticides is done by the Texas Department of Agriculture (TDA) and the U.S. Environmental Protection Agency (EPA).
- The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) governs the sale and use of pesticides.
Applicator Types and Responsibilities
- A private pesticide applicator is one who supervises the use of restricted-use pesticides for agricultural purposes.
- Supervision does not require the applicator to be physically present but must be reachable.
- Licensed applicators must ensure that supervised personnel understand label requirements and regulations.
Record-Keeping and Reporting
- Private applicators must maintain records for two years for restricted-use pesticides.
- Records must document applicator identity, application details, product used, and treated area.
Pesticide Label Importance
- Pesticide labels have legal weight; deviation from label instructions violates federal and state laws.
- Signal words indicate toxicity levels: "Caution" (least toxic), "Warning" (moderately toxic), "Danger" (highly toxic).
- Restricted-use pesticides require certification for safe application.
Environmental and Safety Considerations
- Pesticide application can harm groundwater, necessitating careful practices to prevent contamination.
- Situations increasing leaching risk include sandy soils, shallow groundwater, and excessive pesticide solubility.
- Biological diversity is critical; many pharmaceuticals originate from natural sources.
Worker Protection Standards (WPS)
- WPS applies mainly to agricultural production areas; exemptions include pastures and rangeland.
- Employers must monitor handlers using highly toxic pesticides every two hours for safety.
Personal Protective Equipment (PPE)
- Chemical-resistant PPE includes materials like PVC and rubber; cotton or leather gloves are inadequate.
- Properly wearing PPE involves several guidelines related to clothing and glove usage to minimize exposure.
Cleaning Up and Managing Pesticides
- The proper management of pesticide spills follows the three 'C's: Control, Contain, Clean up.
- Contaminated work clothes must be washed separately using heavy-duty detergent and hot water.
Notification Requirements
- Neighbors within 1/4 mile must be notified prior to pesticide applications using specific equipment.
- Notification can be accomplished through raising an EPA WPS flag or through other agreed methods.
Licensing and Renewal
- Renewal of the private applicator's license requires 15 Continuing Education Units (CEUs) over five years, including legal and IPM credits.
- Failure to renew on time incurs late fees and can result in license suspension if address changes are unreported.### Cleaning and Disposing of Contaminated Items
- Perform two complete washer cycles for moderately to heavily contaminated items.
- Hang washed work clothes outside to dry.
- Run an empty washer cycle with hot water and detergent for additional cleaning.
- Avoid using a dryer; if necessary, use the highest setting. Heavily contaminated clothing should be destroyed.
Pesticide Container Disposal
- Rinse empty pesticide containers three times before disposal.
- Rinse water from triple rinsing should be added to the spray tank and applied at labeled sites.
- Empty, rinsed containers must not be reused; triple rinse and either recycle, recondition, or puncture for landfill disposal. Burning is prohibited in Texas.
Worker Training Requirements
- Worker training must utilize EPA-approved written or audio-visual materials.
- Training information can be personally delivered or through audio-visual programs with the option to involve another approved trainer.
- Ensure training is presented in a language and terms that workers can understand.
Pump Pressures and Capacities
- Rank pumps by pressure: centrifugal (lowest), roller (mid), piston (highest). Centrifugal pumps have higher volume capacity.
- Pump size should supply all spray boom nozzles and provide agitation if necessary.
- Choose a pressure gauge with a range twice the maximum expected pressure.
Nozzle Considerations
- Avoid brass tips for spraying wettable powders.
- Adjust boom height to change spray pattern overlap with flat spray tips.
- Flat and even spray tips can operate between 20 to 40 psi.
Nozzle Flow Rate and Maintenance
- Changing operating pressure can alter nozzle output, but significant changes may require nozzle tip replacement.
- To double nozzle flow rate, increase pressure fourfold, which is impractical for typical psi ranges.
- Clean nozzles with soft brushes like toothbrushes, avoiding knives or wires.
Drift Prevention and Application Timing
- Monitor weather conditions to prevent chemical drift; do not apply chemicals with wind towards sensitive crops.
- Optimal spray application times are early morning and late evening when temperature differences are minimal.
Equipment Calibration
- Calibrate equipment before each use.
- Use water in the tank for checking nozzle discharge or calibrating the sprayer.
Plant and Insect Management
- Recognize plant diseases by symptoms such as leaf spots, blights, and wilts; requires a susceptible host, the organism's presence, and a favorable environment for infection.
- Economic thresholds guide when pest control measures are needed, considering pest population development and damage levels.
Pest Categories and Control
- Insects categorized by impact: 90% have no significant impact, 7% beneficial, 3% economically important or destructive.
- Key, occasional, and secondary pests differ in their economic impact and frequency.
Weed Life Cycles and Control Methods
- Weeds categorized by life cycle: annuals (1 year), biennials (2 years), and perennials (multiple years).
- Control methods include biological (e.g., beneficial insects), mechanical (e.g., mowing, tilling), cultural (e.g., crop rotation), and chemical (caution with herbicide use).
Herbicide Effectiveness
- Herbicide effectiveness varies with the weed growth stage: near 100% effectiveness at seedling stage, drops to 75% at vegetative, less than 40% at flowering, and lowest at mature stage.
