Best Management Practices (BMPs) - ANSWER These are practical, research-based ways for users of pesticides to prevent or minimize contamination. Application Setbacks - ANSWER The distance of untreated land between a pesticide treated area in the areas that need protection from the pesticides. Depth to Groundwater - ANSWER The distance from the soil surface down to the water table. Backflow - ANSWER When the water source filling the pesticide application equipment has a water pressure drop unexpectedly in the supply line, electricity is shut down or a pump fails and the pesticide runs back into the water source, contaminating it. Air Gap - ANSWER A physical separation, or gap, between the water source and the rim of the tank or container you are filling, designed to prevent backflow. Reduced Pressure Principal Device - ANSWER Two independent check valves in the water supply line, with an automatic pressure differential valve located between the two valves. Pressurized Vacuum Breaker - ANSWER Vees stop backflow in the waterline is under continuous water pressure and the waterline pressure is lost. Atmospheric Vacuum Breaker - ANSWER These let air from the atmosphere into the waterline to break the backflow siphon at the event of pressure loss in the waterline. 1 4 Ways to prevent Backflow - ANSWER 1) Airgap 2) Use a reduced pressure principle device 3) Use a pressurized vacuum breaker 4) Use an atomspheric vacuum breaker Chemigation - ANSWER Application of pesticides and fertilizers through irrigation systems (Must have a Chemigation permit to do) Pesticide Waste - ANSWER Includes both pesticides that you cannot use as originally intended, old pesticides that may no longer be effective or pesticides you no longer need or want. Waste Pesticides - ANSWER Pesticides that are no longer usable or wanted. ExamplesThe government has banned the use of the pesticide. The pesticide has been stored too long and lost effectiveness or changed in other ways so it no longer works. The pesticide is left over or you no longer need or want it. Agricultural Chemicals - ANSWER Substances such as pesticides, herbicides, and fertilizers STARR - ANSWER Secure - Key people/children/pet/animals away from site and wear PPE Telephone - if there is a threat to public safety call 911 and or fire department if needed. Then call safety duty officer to report Abate - Control the source of contamination and contain the contamination so it does not spread any further Recover - collect the released chemical and any contaminated soil or other materials Remediate - dispose of recovered chemical in contaminated soil and materials 1 Agricultural Chemical Response and Reimbursement Account (ACRRA) - ANSWER A fund that provides partial reimbursement for cleanup cost for agricultural chemical incidents Adjuvant - ANSWER An additive to a pesticide that enhances pesticide effectiveness. Aquatic life - ANSWER Organisms that spend all or part of their life on surface waters. Direct pesticide application - ANSWER A precise application to a specific area or site so only weeds are sprayed during a band application to crops. Indirect pesticide applications - ANSWER Unintentional or intentional treatment of pests through spraying or placement of a pesticide on a plant rather than on the pest . Leaching - ANSWER The downward movement of pesticides and nutrients through the soil. Non-target species - ANSWER Organisms not intended to be managed Runoff - ANSWER The movement of water and associated Materials over the top of the soil or impervious surfaces. Toxicity - ANSWER The extent to which a chemical or substance is poisonous. Transformation - ANSWER Change in a pesticides chemical structure Transportation - ANSWER The movement of a pesticide away from its intended site of action. 1 Pollinator protection statements - ANSWER EPA required statements on pesticide labels which provide information on use of the product in a manner that reduces impacts on pollinators . Pollinators - ANSWER Insects and other organisms that carry pollen from one flower to another i.e. birds or bees Solubility - ANSWER How well it dissolves in water Particle drift - ANSWER How far the droplets of the pesticide or fertilization goes from the application site. This is unwanted and to be avoided Violatilization - ANSWER This occurs when a pesticide changes from a solid or liquid phase to a gas station a spad this occurs when a pesticide changes from a solid or liquid phase to a gaseous phase. Absorption - ANSWER The movement of pesticides in the plants. Aesthetic threshold - ANSWER The pest population density level when pest management measures must be applied to prevent reaching unacceptable levels of aesthetic damage to a plant or landscape . Calibration - ANSWER The practice of verifying and adjusting fertilizer or pesticide application equipment to accurately apply a predetermined or calculated amount of product per area unit . Economic level injury - ANSWER The pest population density were pest damage causes a reduction in the value of the crop or plant that is greater than the cost of control Economic threshold - ANSWER The pest population density level when pest management measures must be applied to prevent reaching the economic injury level 1 Environmental thresholds - ANSWER The pest population density level when pest management measures must be applied to prevent unacceptable damage to the environment Integrated Pest Management (IPM) - ANSWER A sustainable approach to reduce pest to a tolerable level by using the best balance of cultural physical, biological and chemical message while minimizing economic, environmental and health risks Mode of action - ANSWER The way in which a pesticide exerts a toxic effect on the target plant, annual, or micro organism Pressure sprayer - ANSWER The pesticide solution is forced through the spray system at a specific pressure and sprayer speed. The sprayer may have one or several nozzles. Jobs can be handled by low or high pressure sprayers which can be hand carried compressed air or knacksap sprayers Soil injection - ANSWER The placement of a pesticide below the surface of the soil Spraygun - ANSWER Handheld devices attached to a hose and taking a quick did with the trigger the regulate the application of the liquid from inside the tank Sprayer overlap - ANSWER Intentional application on top of a previous application to account for reduced volume of material applied at the edges of fertilize Asian or herbicide application and to ensure adequate coverage Systematic herbicides - ANSWER There absorbed by the roots or through the foliage and then are translocated to other parts of the plant. Systematic herbicides will work on annual and perennial weeds, but are often used to control perennial weeds Rinsate - ANSWER Water containing low concentrations of contaminants, resulting from the cleaning of containers etc. 1 MSDS - ANSWER Material Safety Data Sheet Diaphragm Pumps - ANSWER A pump using a flexible diaphragm in place of a piston. 3 C's - ANSWER Control - Contain - Cleanup Spot Application - ANSWER Only spray certain areas Broadcast Application - ANSWER The uniform application of a pesticide or other material over an entire field or area. Band Application - ANSWER The placement of fertilizers in about 2 in. to one side of and slightly below the seed. Area of a Rectangle - ANSWER L x W = A Area of a Square - ANSWER L x L = A Area of a Circle - ANSWER (3.14 x r)squared = A Area of a Triangle - ANSWER (B x H)/2 = A Mechanical Control - ANSWER Insect pest control which uses a purpose-built mechanical device or hands (and feet). Biological Control - ANSWER Insect pest control which uses other predators to eat away the pests 1 GPA - ANSWER Gallons per Acre Microbial Decomposition - ANSWER The chemical and physical processes during which organic matter is broken down and reduced to its original elements. Professional Conduct - ANSWER Read the label - don't be inappropriate - don't lie - be polite Filter Stips & Vegetative Buffers - ANSWER Untreated grass strips next to streams, ponds, etc. meant to trap pesticide Household Hazardous Waste Facility - ANSWER In MN - country run facilities that accept most types of hazardous waste Incident - ANSWER In this context: pesticides released into the enviroment beyond what the label permits 1 Minnesota Pesticide Applicators Certification Class C Insect Identification QUESTION Wireworm Answer: Yellowish or Reddish Brown. Hard Shelled, and wire-like. Attack Seed or drill into base of stem below ground. Kills meristematic tissue.
