Idaho Core Study Material
Minimum age for licensed applicator in Idaho - ANS At least 18 years old CE's needed - ANS Private: 7, Professional: 16 Signal word caution toxicity level - ANS Slightly toxic Minimum PPE for pesticide treatment - ANS Cultural control, rotating crops, tilling soil, varying planting time, pruning, thinning, fertilizing plants Systemic pesticides - ANS Absorbed through foliage or roots, translocate through vascular system of treated plant FIFRA administration - ANS By US EPA IPM approach - ANS Combines different control methods to maintain pest levels below economically damaging levels Economic injury level - ANS Level of pest infestation that lowers economic value of crop more than cost of pest control Idaho Pesticide Act of 1976 administration - ANS By ISDA Recertification credits requirement - ANS Professional applicators: 15 credit hours, Private applicators: 6 credit hours Prohibited active ingredients - ANS Aldrin, Heptachlor, Dieldrin, Chlordane, Dinoseb, Endrin
Pesticide records retention period - ANS Private applicators: 2 years, Professional applicators: 3 years Items on private applicator application records - ANS Date of application, Crop/animal/commodity treated, Pesticide product name, EPA Registration Number, Total amount applied, Location, Certified applicator's name and license number Items on professional applicator records - ANS Date/time of application, Crop/animal/commodity treated, Pesticide product name, EPA Registration Number, Total amount applied, Location, Certified applicator's name and license number, Property owner/operator name and address, Rate of application, Wind speed/direction, Worker protection info exchange, Person who recommended application Prevalent pesticide in Idaho waters - ANS Herbicides, particularly soil-applied Insecticide entry into insects - ANS Some swallowed during feeding (stomach poisons), others penetrate outer membrane or respiratory tubes (contact poisons) Emulsifiable Concentrates advantages - ANS Easy to handle, transport, store; little agitation needed; non- abrasive to equipment Emulsifiable Concentrates disadvantages - ANS High concentrations increase mixing error risk; high phytotoxicity hazard; easily absorbed through skin; may cause equipment deterioration; corrosive; flammable Microencapsulated advantages - ANS Easy to transport, handle, store; effective for time-release situations Microencapsulated disadvantages - ANS Constant agitation needed; hazard to bees; longer reentry periods
Organophosphate and carbamate insecticides - ANS Classes of pesticides affecting the nervous system. Atropine - ANS Antidote for organophosphate and carbamate poisoning. 2-PAM - ANS Reactivates cholinesterase in organophosphate poisoning but ineffective for carbamates. Negative-pressure respirators - ANS Respirators relying on lungpower to draw air through purifying materials. Water addition to spray mixture - ANS Water pipe should be above container level to prevent contamination and back-siphoning. Triple-rinsing or pressure rinsing - ANS Rinsing method to render containers non-hazardous and reuse rinsate in future mixes. Carrying pesticides in a truck - ANS Securely storing pesticide containers in the back of a truck to prevent damage. Three C program for spills - ANS Control, contain, and clean up spills of pesticides or hazardous chemicals. Drift of small droplets - ANS Most likely with small nozzle orifices and high pressure during pesticide application. Long distance drift - ANS Associated with stable or temperature inversion conditions during pesticide applications.
Volatilization - ANS Process of a solid or liquid turning into a gas, influenced by conditions like high temperatures. Soil-adsorbed pesticide - ANS Less likely to volatilize, leach, or degrade, with adsorption affected by soil characteristics. Pesticide runoff factors - ANS Dependent on area grade, soil characteristics, moisture, irrigation, and pesticide properties. Factors influencing pesticide leaching - ANS Include water solubility, soil texture, and adsorption properties. Bee-toxic pesticide applications - ANS Restricted to specific hours during bloom to protect bees, based on formulation. Pesticide formulations and bee hazard - ANS Dusts and wettable powders are more hazardous to bees than other formulations. Unclogging nozzles - ANS Use an old toothbrush to avoid distorting nozzle openings, never use metal wire or knife tip. Variables affecting spray solution per acre - ANS Nozzle flow rate and ground speed of the sprayer influence the amount of spray applied.
