Are herbicide sale increasing or decreasing
Herbicide sales are actually decreasing
100
What is overspray
Overspray is when the herbicide spreads beyond where it is meant to be sprayed
100
What are herbicides
Herbicides are a classification of pesticides that kill any sort of plant
100
Name one piece of equipment used in spreading herbicides
Answers may vary (seeder with built in sprayer, plane, etc.
100
what are the 2 different types of herbicides?
Selective and non-selective
200
True or false herbicides are a cost effective solution for unwanted plants
False
200
Why is it better for the soil to be loose
When the soil is compacted it is easier for the chemicals to enter the irrigation system
200
True or false, round-up is the most commonly used herbicide
True
200
What is the difference between pre emergence and post emergence
Pre emergence is before the crops have sprouted post emergence is after
200
Do most herbicides contain acids or bases?
most herbicides use acidic solutions
300
True or false, herbicides are responsible for approx. $40billion of the US agricultural market
False
300
Why would cultivating the land help with contain the herbicides
Because when you cultivate the soil it brings the chemicals close to the surface away from ground water and the irrigation system
300
True or false Many of the chemicals used in agriculturally used herbicides are the same as those in commercially used herbicides
True
300
Name 2 of the 4 ways herbicides are applied
Contact, systemic, spray applied, or soil applied
300
What is the difference between proherbicides and herbicides
Proherbicides are not herbicidal when manufactured and will turn herbicidal when they enter the plant.
400
What effects do herbicides have on live stock
They can cause diarrhea, abdominal pain, thirst and weakness and eventually death
400
Why does the weather play a big role in herbicide application
Certain herbicides need water to be absorbed into the plant while others may get washed into the irrigation systems when it rains
400
Why would pre emergence be better that post emergence
Sometimes in post emergence you can lose some of the crops due to the sprayer having to drive on top of them
400
How do proherbicides work
Proherbicides stop the production of an enzyme that assists fatty acid synthesis, which kills the plant
500
Explain why herbicides have a positive impact on the economy
Because with out herbicides farmers wouldn't be able to produce as much crops
500
Explain how herbicides can travel into our water supply
Herbicides can find their way into the irrigation system in a field which will eventually flow into a major river
500
Name 2 health issues caused by herbicides
Headaches, nausea, cancer, poisoning, reproductive problems, etc
500
what are the 4 ways a herbicide can destroy a plant
contact, systemic, spray applied, soil applied
500
what is the chemical equation for indole acetic acid
C10H9NO2
