Term
legal control
Definition
following state and federal laws that are designed to prevent the spread of pests
Term
cultural conrtol
Definition
using crop rotation cultivation sanitation habitat modification or removal of sources of infestations
Term
physical control
Definition
using barriers, traps, trap crops, planting, fertilization, tillage, or harvest times.
Term
genetic
Definition
using plant resistance to pest injury
Term
biological control
Definition
conservation or introduction of predators, parasites, and diseases that suppress or attack pests
Term
chemical control
Definition
select and use the least toxic environmentally suitable pesticide in the lowest effective amounts to control pests
Term
damage threshold
Definition
lowest level of injury that can be measured- occurs before economic loss- basic IPM principle ensures from damage boundary/economic damage relationship
Term
economic injury level
Definition
lowest population density that cause economic damage- measure against which we evaluate the destructive status and potential of a pest population
Term
economic threshold
Definition
population density at which control action should be determined to prevent increase pest population from reaching the EIL- measured in insect density
Term
action threshold
Definition
time to take action
Term
IPM
Definition
using multiple tactics in a compatible manner, maintain pest population at levels below those causing economic injury while producing protection against hazards to humans domestic animals, and environment
Term
integrated
Definition
broad interdisciplinary approach using scientific principles of plant protection to fuse into a single system of a variety of management strategies and tactics
Term
pest
Definition
reduce availability, quality, or a value of a human resource- pest compete with people for food or fiber, interfere with raising crops or livestock and damage property-include biotic agents-adversly affecting plant production
Term
key pest
Definition
cause major damage on regular basis
Term
occasional pest
Definition
intolerable only irregularly- climate, environment, influences result of human activity
Term
secondary pest
Definition
occur as result of action to control key pests
Term
Management
Definition
decision making process to control pest populations in a planned systematic way by keeping their numbers or damage at an economically acceptable levels
Term
preventative methods
Definition
discourage damaging prest populations from developing -cultural, cultivating- planting and harvest date- soil disinfestation, soil insecticides and fumigation
Term
suppressive methods
Definition
reduce existing pest populations to tolerable levels- release of bio control agents-mowing-cultivation- inseason pesticide sprays
Term
Eradication
Definition
no pest can be tolerated. total elimination of the pest population
Term
DDT
Definition
Dichlorodiphenyltrichloroethane- beginning of insecticide- used for mosquito, flea, louse application
Term
first principle of IPM- agroecosystems
Definition
any management action that does not consider this may produce unexpected and undesirable effects
-soil prep -planting -forecasting -trapping -monitoring -threshold -cultural, biological, chemical controls -record keeping
Term
second principle
Definition
any pest population can exist at the sam tolerable level and this concept can be applied to development of economic injury levels and action threshold
Term
third principle of IPM
Definition
maximizing the effectiveness of natural control factors to regulate pest populations
