Why is it important to use both short term suppression and long term suppression tactics in pest management? Short term suppression - offers a quick fix but the pest population will rebuild. Long term suppression - maintenance must be used to reduce pest populations permanently plant resistance Varieties of grass containing endophyte fungi are one example Mechanical and physical resistance Includes hand removal, traps, barriers and repellents Cultural control includes raking, thatch removal and aeration Give one example of a weed situation that can be managed with hand removal techniques In a new stand of grass, hand removal of weeds may be necessary to prevent damage to the young grass plants explain why turf cannot at the same time benefit from biological control methods and be pest free there must be a low level of pest or prey insects for the predators to feed on How can you help maintain existing populations of beneficial organisms in a turf stand? by making pesticide applications only when needed Are microbial insecticides best used for short term suppression or long term maintenance of pest populations? Why? Long term maintenance. Microbial insecticides are slower acting and do not kill all of the pest at once, which allows there to be food for other beneficial organisms. List four ways to classify pesticides Type of pest Pesticide chemistry Mode of action Pesticide formulation Broad-spectrum pesticide Can be used to control several pests, but more likely to be hazardous to non target organisms. Residual pesticide Good for use when the goal is to reduce the number of applications required to control persistent pests Systemic herbicide Superior in treating persistent perennial weeds, kills both aboveground and below ground parts of the plant
