How can pest identification help you develop a good pest control strategy? -
|| || || || || || || || || || || || ||




✔✔Identification of the pest allows you to determine basic information about it, including || || || || || || || || || || || || ||




its life cycle and the time that it is most susceptible to being controlled.
|| || || || || || || || || || || || ||




Define "integrated pest management" (IPM) and list several possible control tactics that may
|| || || || || || || || || || || ||




be used in an IPM strategy. - ✔✔Integrated pest management is the combining of
|| || || || || || || || || || || || || || ||




appropriate pest control tactics into a single plan to reduce pests and their damage to an
|| || || || || || || || || || || || || || || ||




acceptable level. Pest control tactics may include: host resistance, biological control, cultural
|| || || || || || || || || || ||




control, mechanical control, sanitation, and chemical (pesticide) control.
|| || || || || || || ||




You applied a pesticide, but it did not control the pest. Name three reasons why your
|| || || || || || || || || || || || || || || ||




control effort might have failed. - ✔✔The failure of the pesticide to control the pest might
|| || || || || || || || || || || || || || || ||




have been caused by pest resistance, choosing the wrong pesticide, misidentifying the pest,
|| || || || || || || || || || || || ||




applying the wrong amount, or applying the pesticide incorrectly.
|| || || || || || || ||




What can you do to keep the pests you are trying to control from becoming resistant to the
|| || || || || || || || || || || || || || || || || ||




pesticides you use? - ✔✔Pest resistance can be reduced by using integrated pest
|| || || || || || || || || || || || ||




management and rotating the types of pesticides used. || || || || || || ||




Name four of the six available methods to control pests when natural controls are not
|| || || || || || || || || || || || || || ||




sufficient. - ✔✔The six pest control methods include: host resistance, biological control,
|| || || || || || || || || || || ||




cultural control, mechanical control, sanitation, and chemical control.
|| || || || || || ||




Name the four factors that affect pesticide use outdoors. - ✔✔Pesticide use outdoors is
|| || || || || || || || || || || || || ||




affected by soil factors, surface moisture, humidity and temperature, and wind.
|| || || || || || || || || ||

, What is the best control method for controlling plant diseases? - ✔✔At present, prevention
|| || || || || || || || || || || || || ||




is the only plant disease control measure. Once a plant is infected, few control methods are
|| || || || || || || || || || || || || || || ||




effective, including pesticides. || ||




Name four forms of mechanical vertebrate pest control. - ✔✔Traps, barriers, gunning,
|| || || || || || || || || || || ||




attractants, and repellents are all forms of mechanical vertebrate pest control. || || || || || || || || || ||




What is a pesticide formulation? - ✔✔A pesticide formulation is the mixture of active and
|| || || || || || || || || || || || || || ||




inert (inactive) ingredients that forms a pesticide product.
|| || || || || || ||




What is the difference between active ingredients and inert ingredients? - ✔✔Active
|| || || || || || || || || || || ||




ingredients are the chemicals in a pesticide product that control pests. Inert ingredients are
|| || || || || || || || || || || || || ||




the chemicals in a pesticide product that are added to make the product safer, more
|| || || || || || || || || || || || || || ||




effective, easier to measure, mix, and apply, and more convenient to handle.
|| || || || || || || || || || ||




What types of factors should you consider when you have a choice of formulations for a
|| || || || || || || || || || || || || || || ||




pest control task? - ✔✔You should think about the characteristics of each formulation, and
|| || || || || || || || || || || || || ||




you should consider which of the formulation's advantages and disadvantages are important
|| || || || || || || || || || ||




in your application situation. Also consider the following: Do you have the right application
|| || || || || || || || || || || || || ||




equipment? Can you apply the formulation safely? Will the formulation reach the target
|| || || || || || || || || || || || || ||




and stay in place long enough to control the pest? Might the formulation harm the target
|| || || || || || || || || || || || || || || ||




site?



If you had a choice of either a wettable powder formulation or a granular formulation for a
|| || || || || || || || || || || || || || || || ||




particular pest control task, which would be best if drift were a major concern? Which
|| || || || || || || || || || || || || || ||




would be best if you need the pesticide to stay on a surface that is not level, such as foliage?
|| || || || || || || || || || || || || || || || || || || ||




- ✔✔The granular formulation would be the best choice in the first situation, because
|| || || || || || || || || || || || || ||




granules have a much lower drift hazard than wettable powders. Granules do not stick to
|| || || || || || || || || || || || || || ||




nonlevel surfaces, so the wettable powder would be the best choice in the second situation.
|| || || || || || || || || || || || || ||




Why are adjuvants sometimes added to pesticide formulations? - ✔✔Adjuvants are added to
|| || || || || || || || || || || ||




a pesticide formulation or tank mix to increase its effectiveness or safety.
