QUIZZES AND SOLUTIONS
What are examples of plant diseases? - Fungi,Oomycetes,Bacteria,Viroids,
Oomycetes can be describe as - Water Molds
prerequisites for a plant disease - population, Host, ideal environment, time,
Largest Group of plant diseases - Fungi
A Chemical Formulation capable of causing injury to plants - Phytotoxic
Reasons to consider treating an infected area with pesticides - When other prsctices don't
work,high value,quality reduced,sudden breakout
What is abiotic - Non-living (example wind damage)
What is biotic? - living (Example Fungi)
T or F Should you avoid driving through field when foliage is wet, to prevent diseases. -

What is a Pest - any organism that competes with people for food, fiber or space, or
presents a health risk to people or domestic animals

What is an Arthropod - Arthropods are invertebrate animals with an exoskeleton, like
insects and arachnids
What type of damages do arthropods cause - Chewing on leaves, Tunneling in roots,
Sucking on plant, cause galls, Inject toxins, transmit diseases, feed on livestock
Difference between insects and arachnids - Insects have 3 pairs of legs, wings and
antennae 3 regions of the body head, thorax and abdomen. While arachnids have 4 pairs
of legs, not wing and no antennae 2 regions head and thorax.
What is the difference between simple metamorphosis and complete metamorphosis -
Simple Metamoph. is 3 stages egg, nymph, and adult. gradual change. Complex
Metamorph. 4 distinct stages egg, larva, pupa, and adult
How dose Temp. and Humidity effect insect development. - Higher temp and humidity is
typically better for insects. Temp above threshold will increase reproduction and
humidity will decrease stress.
Corn ear worm properties - can vary in color grow 1 inch 1/2 long
Advantages of using insecticides - effective against thousands of insects, they act quickly,
effectiveness can be evaluated quickly, equipment and formulations are common
disadvantages of insecticides - the wide range can kill beneficial insects, reapeated use
can lead to resistance, added cost of production, potential for drift to areas with benifical
insects
Describe ways insecticides are used - Seed Treatment, Soil Application (in Furrow), foliar
application to leaves or fruit.

Define weed - Unwanted Plants, we consider all plants except the crop to be a weed.
Two Main Goals of weed management. - Minimize weed competition, and yield loss.
Other main goal is to limit a weeds reproductions to reduce weed population in future
years.
Describe ways weeds can pose problems in crop production - Compete with crops,
Reduce crop quality, interfere with production, produce chemical inhibitors, Irritate or
poison, support insects and diseases,
What is a grass - monocots ( corn)
what is a broadleaf - Dicots ( soybeans)
Ways to distinguish a grass. - one cotyledon (seed leaf) growing point is at or below soil
surface, fibrous root system, Parallel vein pattern on leaves.
Ways to distinguish a broadleaf. - Two leaves(cotyledons) when they emerge, often
looking like the true leaves. growing point at tip of shoot above ground, taproot system,
Net like vein pattern on leaves.
What is an annual plant. - live less than 12 months and produce and abundance to seeds
for next year.
What is a summer annual - Germinate from seed in spring flower and produce seed
during sumer and then die in the fall/ winter .
WI pesticide applicator
, WI pesticide applicator
what is a winter annual. - germinate from seed in fall, over winter as low growing plants,
flower and produce seed next spring and then die.
what is a Biennial - a plant that lives for two growing seasons, it germinate from seed in
spring or summer, over winter in the rosette stage, and then the following year flower,
seed and then die.
what is a Perennial - a plant that lives for at least 2 or more years and can reproduce via
seed alone or may also spread by vegetative growth
How to kill Biennials and anuannal weeds - you must kill the whole shoot, if the shoot is
cut of with tillage or killed with herbicides it will not grow back from roots
How to kill perennial weeds - destroy underground vegetative structure, by reputably
tilling or using herbicides that translocate and destroy the complete vegetative system.
describe preplant application - before the crop is planted
Describe Preemergence application - applied before the crops and/or weeds emerge,
tyipicaly after planting but not always. ( just before emergence)
Postemergence application - application after crop/weeds have emerged.
What effects dose soil texture, organic matter and ph have on herbicides. - different rates
for fine(Clay) vs Coarse(Sand) soils. typically higher rates for fine soils because it bines
to soil instead of target weed. same applies for organic Matter, More leaching in coarse
soils, Valorization and erosion are also factors
