What should you do first if you see damage to a plant, animal, or valuable product?
Omdraaien
Identify the cause.
What should you do first if you discover a pest that may need to be controlled?
Omdraaien
Make sure the pest is actually responsible for the damage, then accurately identify the pest.
How can pest identification help you develop a good pest control strategy?
Omdraaien
It allows you to determine basic information about the pest, including its life cycle and when it is most susceptible to control measures.
Name the 5 basic pest groups.
Omdraaien
Weeds, parasites and diseases, mollusks, arthropods, and vertebrates.
Why do weeds present such a challenge to pest managers?
Omdraaien
Weeds are often hardy, aggressive, and tolerant of harsh conditions. Many produce large numbers of seeds, which can spread over a wide area and remain dormant for a long time.
How can you tell a monocot from a dicot?
Omdraaien
Monocots (sedges and grasses) have one cotyledon, parallel leaf veins, flower parts in multiples of 3, and fibrous roots. Dicots have 2 cotyledons, broad leaves with netted veination, flower parts in multiples of 4 and 5, and usually have taproots.
Name the pathogens that cause most plant and animal diseases.
Omdraaien
Fungi, bacteria, mycoplasma, and viruses.
