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