True/ False-- Plant health care and integrated pest management are essentially the same thing.
Plant resources, produced through photosynthesis, are allocated among four primary functions:
a. Growth
b. Maintenance (reproduction)
c. storage
d. Defense
(Blank) can be described as any factor that limits a plant's ability to acquire sufficient light, water or essential minterals
The (Blank) and (Blank) in tree cells are indigestible to many insects and other animals, and even to some pathogens.
Cellulose, Lignin
Trees produce (Blank) such as tannins and phenols that have toxic or deterrent effects on certain insects.
True/ False-- Researchers have observed that rapidly growing trees are sometimes less resistant to certain insects and diseases.
(Blank) is the process of observing, identifying, recording, and and analyzing what happens with plants in the landscape.
The process of gathering information, assessing the severity and implications of the problem, determining client expectations, and deciding on a course of action is called (Blank)(Blank)(Blank)
appropriate response process
(Blank)(Blank)(Blank) is a systematic approach to insect and disease management that incorporates a combination of techniques including resistant plants as well as cultural, biological, and chemical control tactics
Integrated Pest Management
True/ False-- A simple degree-day model uses an established threshold temperature and the daily average temperatures to predict pest development stages.
When possible, arborists should select trees that are (Blank) to known insects or diseases.
(Blank)(Blank) are organisms that are frequently encountered in landscapes, predictably cause injury to landscape plants, and may include particularly noxious pests in the area.
Key Pests
Extensive plantings of the same species, known as (Blank), can have catastrophic consequences if an uncontrollable problem is introduced.
PHC practitioners must choose from three pest management goals: (Blank),(Blank) and (Blank).
Preventions, eradications, suppression
True/ False-- Pesticides often kill the targeted pest within minutes or hours of applications, wheras biological control can take days or weeks to suppress a pest population
(Blank) pesticides are taken up by the plant and translocated throughout the branches and into the leaves.
(Blank)(Blank) occurs when the pest population rapidly rebounds in the absence of natural enemies, which are slower to repopulate than the pest.
Pest resurgence
True/ False-- The use of multiple pesticides with different active ingredients or modes of action in a rotation system will increase the incidence of pesticide resistance.
True/ False-- Insecticidal soaps disrupt the cell membranes of soft-bodied insects and are effective on some scales aphids, mealybugs, and spider mites.
True/False-- Horticultural oil applications are always safe to use on trees in leaf because they have no phytotoxic properties.
(Blank)(Blank)(Blank) are synthetic compounds that act like insect hormones.
insect growth regulators
(Blank)(Blank) are derived from certain bacterial pathogens of insects.
microbial pesticides
Products that contain (Blank)(Blank) (bt) are examples of microbial pesticides that utilize insect pathogens or lethal microbial byproducts derived from extracts of bacterial pathogens of insects.
Bacillus thuringiensis
The beiological control strategy is based on the concept tha many insect pests live in a natural, dynamic balance with (Blank),(Blank)(Blank) and (Blank) that control pest populations.
predators, parasites and pathogens
True/ False-- PHC practitioners should identify short- and/or long term stress factors and remediate them using appropriate management techniques
select two species of trees in your area that have different genetic strategies for resource allocation. Compare and contrast the advantages and limitations of each
fill in the blank
Describe some of the defese mechanisms found in trees and discuss how they can be effective in limiting certain pests.
fill in the blank
discuss the various treatment and control strategies that can be implemented in control pest problems on plants and explain the advantages and limitations of each.
fill in the blank
Plant Health Care is comprehensive program to manage:
a. insects and disease of plants
b. tree health without the use of pesticides
c. the appearance, structure, and health of plants
d. pests, pathogens and abiotic disorders of trees
c. the appearance, structure, and health of plants
The mortality spiral describes the:
a. process of infection and spread of disease
b. cumulative effects of stress causing decline of plant over time
c. process in which pesticides eradicate both pests and beneficial insects
d. allocation of resources among growth, storage, and defense
b. cumulative effects of stress causing decline of plant over time
The process of gathering information assessing the severity and implications of the problem, determining client expetations, and deciding on a course of action is called:
a. the appropriate response process
b. integrated pest management
c. the cultural control mechanism
d. plant health care
a. the appropriate response process
A systemic pesticide is one that:
a. kills all living organisms
b. mechanical control
c. biological control
d. chemical control
c. biological control
