Environmental Considerations Flashcards
T/F: sometimes even small environmental changes can greatly reduce the chances of survival for fish and wildlife
True
When a pesticide volatilizes and moves off target, this movement is called:
Vapor drift
Which of these factors does not influence drift?
Pollution and reentry interval
What factors do influence drift?
Particle size, nozzle design and orientation, and temperature
Why should we protect honeybees?
Their work as pollinators in needed for crop production
T/F: only pesticides that are applied incorrectly are likely to move downward with rain or irrigation water into the water table below
False
T/F: a pesticide becomes a pollutant and potentially dangerous when it is applied at a higher dose than recommended on the label or when it drifts off target
True
How should you change pressure to reduce liquid droplet drift?
Reduce pressure to increase droplet size
What are the possible consequences of pesticide drift onto forage and pastureland or into drinking water?
The pesticide could injure people, pests, and livestock
Pasture grasses could be destroyed
Milk or meat could have illegal residues if the cattle eat contaminated forage
Water may become too contaminated to drink
T/F: Pesticide pollution can help a pest that you are trying to destroy by killing its predators and parasites
True
A/an ________ is a geological formation of permeable rock, sand, or gravel that stores large amounts of water
Aquifer
Why are aquifers important?
Many people use water from aquifers for drinking
The best protection against groundwater pollution is ______
preventing contamination
T/F: Even though persistent pesticides remain in the environment, they do not always accumulate in animals or plants
True
A/an ____________ is a plant or animal that is near extinction throughout all or most of its range
endangered species
