FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) -ANSWER Regulates production, transport, sale, use, and disposal of pesticides FIFRA Section 3 -ANSWER Full federal registration FIFRA section 24c -ANSWER Special local need (application site or alternate control technique not on label) FIFRA Section 18 -ANSWER Emergency exemption (pest with no current control) the federal worker protection standard -ANSWER Reduce risk of employee exposure to pesticides Clean Water Act -ANSWER (CWA, 1972) set maximum permissible amounts of water pollutants that can be discharged into waterways; aims to make surface waters swimmable and fishable Pesticide Hazard -ANSWER Risk = toxicity x exposure Phytotoxicity -ANSWER Injury or damage to a sensitive plant caused by a chemical exposure Adjuvant -ANSWER Product added to spray tank to assist pesticide in application Emulsifiable Concentrate (EC) -ANSWER A pesticide formulation produced by mixing an active ingredient and an emulsifying agent in a suitable petroleum solvent. When combined with water, a milky emulsion is usually formed. Easy to handle and easy on equipment. Flowables (F or AF) -ANSWER Insoluble solid active ingredients ground and mixed with liquid. Forms a suspension (slurry) when ready to use. Requires agitation and leaves residue. Solutions (S) -ANSWER AI dissolved in liquid carrier. Does not settle when mixed with water. Ready-to-Use (RTU) low concentrate solutions -ANSWER Do not require further dilution before application. Consist of small amount of active ingredient (often 1% or less per unit volume). Expensive. Ultra Low Volume (ULV) -ANSWER Have almost 100% active ingredient, used as is, or diluted only a little bit. Applied as very fine droplets (high drift potential). Requires specialized equipment. Aerosols (A) -ANSWER Fine liquid droplets with small amounts of AI. Some are ready to use (bug spray). High drift and inhalation potential. Dry Formulations -ANSWER Dry material suspended in water. High percentage of AI measured by weight. Require constant agitation. Dusts and Granules -ANSWER Ready to use, reach hard to get places. Very little AI. Baits -ANSWER An active ingredient mixes with an edible substance or some other attractant. Low AI percentage (less than 5%). Granules and Pellets -ANSWER Dry, ready-to-use materials usually containing from 2-15% active ingredient. Most granules are prepared by applying the active ingredient as a liquid to a coarse, porous, solid. Granular formulations are applied to the soil where the active ingredient can then be absorbed by the roots and trans-located through the plant. Relatively low AI. Microencapsulation -ANSWER Liquid or dry pesticide coated in latex. Breaks down with water. High hazard to bees. Fumigants -ANSWER Small molecules which are delivered as a gas to penetrate soil or other materials. Must be used in closed sp
