Pesticide Applicator Certification Michigan Latest Version Graded A+ Define integrated pest management IPM is a planned pest control program that combines control program that combines control strategies to keep the pest population below economically damaging levels and to avoid adverse effects to humans, wildlife, and the environment. List three control strategies and give an example for each Cultural Control- Host plant resistance, maintaining healthy plants, changing the timing of harvest or planting, cultivation, field management, water management Biological Control- pathogens, parasitoids, predators Chemical Control- insecticide, herbicide, fungicide Define economic threshold The number of pests that requires a control action to prevent the pest population fromm increasing and causing economic damage. A high value crop will usually have a high economic threshold False Field scouting is important because it helps determine pest: Presence, Location, Life Stage When scouting a field, you should sample only from: Randomly picked locations throughout the field List three ways that cultural controls work 1. Preventing the pest from colonizing the crop or commodity 2. Creating adverse conditions that reduce survival of the pest, and 3. reducing the impact of injury by the pest Which of the following is an example of a biological control? Parasitoid Host plant resistance is a form of? Cultural control When plant species eliminate other plants by releasing toxic chemicals, it is called Allelopathy After the growing season, destroying or removing crop residue can help reduce potential insect and disease problems the following year True Pesticides are NOT part of an IPM program? False Herbicides that are applied and mixed into the soil before crop planting are called__________ Herbicides Preplant incorporated Very weedy cornfield; the corn is knee high Curative A neighboring field is infected with a disease and you dont want it in your field Preventive The MSU Crop Advisory Team alerts you to potential pest outbreaks in your area Preventive You apply a fungicide to get rid of a disease Curative When scouting a field, you find that the potato leafhopper populations is above the economic threshold Curative How are tolerance and pesticide residues related? Tolerance is the amount of acceptable pesticide residue permitted by the EPA on a harvested crop Typically a fly or tiny wasp that develops inside another insect parasitoids
