Complete Solutions|| GRADED A+
What are examples of plant diseases? -CORRECTANSWER
Fungi,Oomycetes,Bacteria,Viroids,
Oomycetes can be describe as -CORRECTANSWER Water Molds
prerequisites for a plant disease -CORRECTANSWER population, Host, ideal
environment, time,
Largest Group of plant diseases -CORRECTANSWER Fungi
A Chemical Formulation capable of causing injury to plants -CORRECTANSWER
Phytotoxic
Reasons to consider treating an infected area with pesticides -CORRECTANSWER
When other prsctices don't work,high value,quality reduced,sudden breakout
What is abiotic -CORRECTANSWER Non-living (example wind damage)
What is biotic? -CORRECTANSWER living (Example Fungi)
,T or F Should you avoid driving through field when foliage is wet, to prevent diseases. -
CORRECTANSWER T
What is a Pest -CORRECTANSWER 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 -CORRECTANSWER Arthropods are invertebrate animals with
an exoskeleton, like insects and arachnids
What type of damages do arthropods cause -CORRECTANSWER Chewing on leaves,
Tunneling in roots, Sucking on plant, cause galls, Inject toxins, transmit diseases, feed
on livestock
Difference between insects and arachnids -CORRECTANSWER 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 -
CORRECTANSWER 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. -CORRECTANSWER Higher
temp and humidity is typically better for insects. Temp above threshold will increase
reproduction and humidity will decrease stress.
Corn ear worm properties -CORRECTANSWER can vary in color grow 1 inch 1/2 long
Advantages of using insecticides -CORRECTANSWER effective against thousands of
insects, they act quickly, effectiveness can be evaluated quickly, equipment and
formulations are common
disadvantages of insecticides -CORRECTANSWER 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 -CORRECTANSWER Seed Treatment, Soil
Application (in Furrow), foliar application to leaves or fruit.
Define weed -CORRECTANSWER Unwanted Plants, we consider all plants except the
crop to be a weed.
Two Main Goals of weed management. -CORRECTANSWER 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 -CORRECTANSWER
Compete with crops, Reduce crop quality, interfere with production, produce chemical
inhibitors, Irritate or poison, support insects and diseases,
What is a grass -CORRECTANSWER monocots ( corn)
what is a broadleaf -CORRECTANSWER Dicots ( soybeans)
Ways to distinguish a grass. -CORRECTANSWER 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. -CORRECTANSWER 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. -CORRECTANSWER live less than 12 months and produce
and abundance to seeds for next year.
What is a summer annual -CORRECTANSWER Germinate from seed in spring flower
and produce seed during sumer and then die in the fall/ winter .
