MI Pesticide Applicator cheat sheet

FIFRA requires EPA registration before a pesticide may be sold, distributed, or used; using an unregistered pesticide is unlawful unless an emergency exemption or special local need registration applies.

Michigan Part 83 of Act 451, the Natural Resources and Environmental Protection Act, governs pesticide registration, dealer licensing, applicator certification, use, and enforcement by MDARD.

The label is legally binding: applying a pesticide in a manner inconsistent with its labeling is misuse under FIFRA and can lead to civil or criminal penalties.

Restricted-use pesticides may be applied only by certified applicators or by noncertified persons working under a certified applicator's direct supervision as the label allows.

Section 18 of FIFRA allows EPA to authorize emergency use of an unregistered pesticide for a limited time and specific site; Section 24(c) allows a state special local need use.

Michigan certified commercial applicators must keep pesticide application records for at least 3 years; federal records for restricted-use pesticide applications must be kept at least 2 years.

The Worker Protection Standard requires agricultural employers to provide pesticide safety training to workers and handlers before work and at least every 12 months, plus decontamination supplies and REI protection.

A certified applicator credential is issued by MDARD; applying a restricted-use pesticide without the required certification or supervision is a violation.

Signal words rank acute toxicity: Danger, often with a skull and crossbones for Category I, is most toxic; Warning is next, followed by Caution.

The main exposure routes are dermal, inhalation, oral, and ocular; dermal contact is the most common route for agricultural applicators.

PPE requirements on the label are minimum legal requirements; chemical-resistant gloves, coveralls, boots, eyewear, and respirators must match the product and task.

Organophosphate and carbamate insecticides inhibit cholinesterase; poisoning signs include headache, nausea, sweating, salivation, blurred vision, and muscle twitching.

First aid for skin contact: remove contaminated clothing, wash with soap and water, and call Poison Control at 1-800-222-1222; for eye contact flush for at least 15 minutes.

Heat stress and pesticide poisoning can both cause dizziness and sweating; heat stress usually improves with cooling and fluids, while pesticide poisoning may worsen.

Spill response: stop the source, evacuate and warn people, contain the liquid, protect drains and water, use absorbent material, and report spills that meet Michigan or federal thresholds.

A tight-fitting respirator requires a medical evaluation, fit test, and training; cartridges must be selected for the label-specified hazard and changed on schedule.

The restricted-entry interval is the minimum time after application that workers may not enter treated areas without label-specified early-entry PPE.

IPM combines prevention, cultural, mechanical, biological, and chemical tactics; chemical control is used when scouting and thresholds show it is needed.

The economic threshold is the pest density at which treatment prevents the pest from reaching the economic injury level; the EIL is the lowest density that causes loss equal to control cost.

Scouting uses regular counts, sweep nets, traps, and records to identify pests and beneficials and to determine pest life stage and population trend.

Degree-day models estimate insect development from daily temperature; pheromone traps detect adult flight and help time scouting or treatment.

Resistance management rotates IRAC or FRAC mode-of-action groups, uses labeled rates, and avoids repeated applications of the same single mode of action.

The disease triangle requires a susceptible host, a virulent pathogen, and favorable environment; modifying one factor can reduce disease.

Conservation biocontrol protects natural enemies by limiting broad-spectrum insecticides, providing habitat, and using selective products when treatment is necessary.

Michigan invasive pests include emerald ash borer, spongy moth, spotted lanternfly, brown marmorated stink bug, and hemlock woolly adelgid; early detection supports rapid response.

Formulation codes include EC emulsifiable concentrate, WP wettable powder, WDG water-dispersible granule, SC suspension concentrate, G granule, and bait; each affects mixing, drift, and residue.

Adjuvants such as surfactants improve wetting and spreading, but they may be prohibited or required by the label and can increase phytotoxicity or runoff.

A pesticide label includes the EPA registration number, signal word, active ingredients, PPE, REI, directions for use, storage and disposal, and restricted-use statement when applicable.

Soil adsorption increases with organic matter and clay; low-organic-matter sandy soils and shallow water tables raise groundwater leaching risk.

Environmental breakdown includes hydrolysis, photodegradation, and microbial degradation; half-life describes how long a pesticide persists under given conditions.

Volatility and drift increase with fine droplets, high temperature, low humidity, and inversions; buffer zones and coarse droplets reduce off-target movement.

Lipophilic, persistent pesticides can bioaccumulate and biomagnify in food chains; runoff and erosion move soil-bound pesticides into surface water.

Application timing, incorporation, buffer strips, and drift-reducing nozzles reduce runoff and off-target exposure; label setbacks and buffer zones are enforceable.

GPA = (GPM per nozzle x 5940) divided by (MPH x nozzle spacing in inches); use consistent units and recalibrate when speed, pressure, or nozzles change.

1/128 acre equals 340 square feet; at 20-inch nozzle spacing the calibration course is 204 feet, and ounces collected per nozzle over that course equal gallons per acre.

Calibration sequence: check nozzle output and pattern, measure ground speed, determine sprayer output, calculate GPA, and adjust pressure or speed to match the label rate.

Nozzle output varies with pressure approximately as the square root of pressure; doubling pressure increases flow by about 41 percent, not 100 percent.

Replace nozzles when output exceeds the new-nozzle rate by about 10 percent or the pattern is visibly worn or streaked.

Fine droplets improve coverage but increase drift; coarse droplets reduce drift but can increase runoff and reduce penetration into dense canopies.

Record each application with date, time, site, crop, pest, product name and EPA number, rate, area treated, applicator certification number, and weather.

Triple rinsing and proper container disposal prevent cross-contamination; rinse water must be added to the spray tank or disposed of according to the label and Michigan rules.
