Term Definition

Biomagnification some organisms accumulate chemical residues in higher concentrations than those found in the organisms they consume

Practice questions for this set Terms in this set (82) IPM Components(1) ID pest and understand biology, (2) monitor the pest to be managed (3) develop pest management goal (eradication, supression, prevention), (4) implement IPM management program, (5) record and evaluate results Key pests may cause regular damage unless controlled (e.g., weeds) Occasional pestscause problems only periodically, usually based on lifecycle and environmental factors (e.g., ants) Secondary pests become pronlematic after another pest is controlled and a niche is exposed Economic thresholdpest population density at which control is required to prevent economic injury level Econimic injuy level pest population densith causes losses equal to the cost of control measures Action threshold pest level at which management action must be taken Pesticide resistanceability or insect, fungas, rodent, weed, or pest to tolerate a pesticide that once controlled it FIFRAenacted in 1947, ammended in 1972, 75, 78, 88. Federal law regulating pesticide use Unclassified uselower toxicity than restricted use and less potential to harm humans or the environment - most "would be" general use pesticides are unclassified Private applicator using chemical on property that you own rent or lease Commercial applicatoruse restricted use pesticide on property exempt from those defined under the private applicator definition Tolerancemaximum residual limit that may remain in crops or products sold for food or feed, set by EPA FFDCA governs establishment of pesticide tolerances for food and feed products FQPAestablished single health-based standard to be used when assessing risk of pest residues in food or feed

EPA may issue exemption to state, Section 18 Section 25(b) FIRFAminimum risk pesticied identified as exempt under this section do not require EPA label and are not reviewed by the EPA. Active ingredientchemical in a pesticide product responsible for the pesticidal activity, concentrated Inert ingredientsnot usually named, but the percentage is reflected on the label, improve application effectiveness (stabilize active ingredients), do not possess pesticidal activity Chemical name identifies chemical composition and must be stated on the label Registration numbers indicates that the product has been registered and the label approved by the EPA Establishment number identidies the facility that produced the product Signal wordgives users a relative indication of the toxicity of the product: Danger - poison, Danger, Warning, Caution Pesticide formulationMixture of active and inert ingredients, usually needs to be mixed with water or oil for final application e.g., 80% SP80% by weight of AI and is a soluable powder. Thus a 10 lb bag has 8 lbs of AI and 2lbs of innert ingredients

Wettable Powders (W or WP)Dry, finely ground formulations the look like dusts. Usually mixed with water for spray application. Contain 5-95% AI. particled dont dissolve in water and require constant agitation to remain in suspension. Soulble Powders (SP or WSP)Look like wettable powders, but readily dissolve in water and form a true solution, usually 50-95% AI by weight Water-dispersible Granules (WDG or Dry FlowablesSimilar formulation to WP's, except instead of dust they are small easily measured (DF)granules. Must be mixed with water to be applied. Require constant agitation Microencapsulated materialsMixed with water and used as spray, plastic coating breaks down and AI is slowly delivered Water-soluble Packets Reduce mixing and handling hazards of some highly toxic pesticides Attractants Pheromones such as meat, sugars, syrups... Impregnates E.g., dog collar with insect repellant Fumigants Pesticides that form poisonous gasses when applied Tank mixCombining 2 or more pesticided and or fertilizers in the same take for dual purpose application IncompatibilityCondition that prevents 2 or more pesticides from mixing properly to form a solution or suspension AdjuvantsChemicals that do not produce pesticidal activities. Improve mixing or application or enhance performance of AI SurfactantWetting agents or spreaders. Physically alter the surface tension of a spray droplet, enlarging the area of the pesticide coverage. Too much or too little can cause runoff. Sticker Adjuvant that increases adhesion of solid particles to target surface
