4

In order for a disease to develop, you must have three factors come together including

- environment, host and pathogen
- pathogen, time and temperature
- fire, wind and water
5

Most plant diseases are caused by
- bacteria
- virus
- nematodes
- fungi
6

Fungi are most commonly spread from plant to plant by what two means
- wind and tools
- soil and insects
- water and insects
- wind and water
7

Identify three common fungal plant disease names
- shot hole, ring spot freckles
- blight, leaf curl, anthracnose
- mosaic, blight, leaf spot
- gall, stunting, mottle
8

Bacterial pathogens require this in order to initiate an infection of host tissue
- high relative humidity
- temperatures above 50F
- high sugar source
- an open wound or natural opening
9

The basic propagule for fungal pathogens is called
- the spore
- the sporangium
- the seed
- the gamete
10

The two practical things that can be used to diagnose a bacterial disease include
- microscope and tweezers
- a halo and appearance of the lesion
- sore morphology and ooze test
- a halo and the ooze test
11

Crown gall is a bacterial disease that affects many plants in the rose family. Which plant not in the rose family was brought into class showing this disease?
- viburnum
- ivy
- periwinkle
- euonymous
12

Plant pathogenic nematodes are tiny round worms that feed on plant tissues by using what apparatus? (hint: only nematodes that feed on plants have this)
- stinger
- stylet
- dagger
- dinger-donger
13

Nematodes cause mild symptoms that are hard to recognize since most of them feed on the roots of plants what two above-ground symptoms might describe this best?
- stunting and necrosis
- yield reduction and leaf spot
- galls and ring spots
- stunting and chlorosis
14

Plant viruses cause a variety of symptoms including a reduction in growth and abnormal growth. You could include with these such terms as mosaic, mottle and ring spot
- True
- False
15

Since viruses are not very mobile, they are most commonly moved from plant to plant by what?
- wind
- insects
- water
- contaminated soil
16

Non-infectious diseases are also known as disorders because
- you cannot diagnose them
- they do not spread from plant to plant
- phytopathologists like it that way
- the instructor said so
17

A non-infectious disease would include which of the following?
- excessive water, fertilizer and pesticide
- ozone, salt burn and high emperatures
- poor pruning, alkaline soils and sclping the lawn
- over watering, compacted soil and too much light
- all of the above
18

IPM stands for which of the following?
- institutional pest maintenance
- integrated post maintenance
- intuitive pest management
- integrated pest management
19

Before you can control a pest problem, you must first do what?
- identify the pest and life cycle
- give it a name
- figure out if it is aesthetically damaging
- ask a Master Gardener
20

The management strategies used in PTM are categorically
- pruning, mechanical, parasites, herbicides
- mechanical, biological, physical, cultural
- resistance, cultural, physical, prayer
- cultural, mechanical, biological, chemical
21

Which strategic action would be considered cultural IPM?
- applying a herbicide
- sticky traps
- improving drainage
- row covers
22

Of all the problems that you might encounter in the landscape, the majority of these can be attributed to diseases, pests and weeds
- True
- False
23

Which principle of disease management fits with the philosophy of IPM?
- pesticides should never be used
- prevention is superior to eradication
- resistant varieties work best
- lowing plant diversity minimizes problems
24

If you compare signs of a disease to the symptoms, an example of a sign would be
- a yellow halo
- mycelium and spores
- wilting
- leaf spot
25

Every pesticide label has safety information. The most important piece of information are the signal words What is the order from most toxic to least toxic?
- caution, danger, poison
- warning, danger, caution
- danger, warning, caution
- caution, warning, danger
