True
Acrolein
A. Originally developed as an aquatic herbicide.
B. Can be used as a burrow fumigant for ground squirrels.
C. At low doses, irritates the treat and eyes, serving as a warning agent.
D. Skin contact causes chemical burns in humans.
E. b. and c. are correct
F. All of the above
F
Aluminum Phosphide: A. A fumigant for certain burrowing rodents and moles B. Crystals react with atmospheric moisture to release phosphine gas (PH3) C. Not very toxic to humans D. Causes internal hemorrhaging E. a. and b. are correct F. b. and c. are correct G. All of the above
E
(True or False)
A first generation anticoagulant are also referred to as “single feed” anticoagulants since a lethal dose is received in one feeding.
False (First generation anticoagulants are multi feed baits; 2nd generation is the the single feed.)
Bromadiolone, brodifacoum, and difethialone are:
A. Burrow fumigants
B. 2nd generation anticoagulants
C. repellants used to protect new growth on shrubs and trees
D. 1st generation anticoagulants
B
(True or False)
Warfarin, pindone, caumafuryl and valone are 1st generation anticoagulants.
True
What was the first anticoagulant insecticide? A. Difethialone B. Pindone C. Valone D. Warfarin
D
Why do anticoagulants have such low susceptibility to bait shyness?
A. They are very palatable
B. They effects are not seen immediately so rodents don’t know the source of their illness.
C. The rodents die before they are able to warn others
D. The AI affects the circulatory system; it is the nervous system affecting AI that cause irritation in rodents that produces bait shyness.
B
What is the antidote for an anticoagulant poisoning? A. PIP-50 B. Vitamin K1 C. Calcium D. There is no antidote
B
Bromadiolone: A. A fumigant for certain burrowing rodents and moles B. Crystals react with atmospheric moisture to release phosphine gas (PH3) C. Not very toxic to humans D. Causes internal hemorrhaging E. a. and b. are correct F. b. and c. are correct G. All of the above
