Pesticide Application and Weed Control Quiz
Test your knowledge on weed control methods, herbicides, and resistance mechanisms in this comprehensive quiz on weed science.
#1
Which type of pesticide targets a wide range of pests and is not specific to a particular species?
Insecticide
Herbicide
Fungicide
Broad-spectrum pesticide
#2
Which of the following is not a method of weed control?
Mulching
Irrigation
Cultivation
Biological control
#3
What does the term 'non-selective herbicide' imply?
It targets only a specific species of weed.
It is safe to use around all crops without causing harm.
It kills or inhibits the growth of all plants it comes into contact with.
It is only effective during a specific phase of the plant's life cycle.
#4
Which of the following is a cultural weed control method?
Using herbicides
Applying mulch
Using mechanical tillage
Releasing biological control agents
#5
What is the recommended method for disposing of leftover pesticides?
Pouring them down the drain
Burying them in the garden
Returning them to the store
Following local hazardous waste disposal guidelines
#6
What is the primary purpose of pre-emergence herbicides?
To control weeds after they have emerged
To control weeds before they germinate and emerge
To control insects
To promote plant growth
#7
Which of the following is a common selective herbicide used to control broadleaf weeds in lawns?
Glyphosate
Paraquat
2,4-D
Atrazine
#8
What is the mechanism of action of contact herbicides?
They are absorbed by the roots and move through the plant's system.
They kill only the plant parts they directly touch.
They increase the plant's growth rate until it dies.
They inhibit photosynthesis throughout the plant.
#9
Which of the following is a benefit of using integrated pest management (IPM) for weed control?
It relies solely on chemical herbicides.
It reduces the need for pest control through the use of a single method.
It combines cultural, biological, mechanical, and chemical methods to minimize weed impact.
It ensures the complete eradication of all pests.
#10
What is the primary goal of using crop rotation as a weed management strategy?
To increase soil fertility
To reduce pest populations by alternating host crops
To improve soil structure
To prevent the establishment of weed populations adapted to specific crops
#11
What is the term for the practice of rotating different herbicides to prevent the development of resistance in weed populations?
Herbicide alternation
Resistance management
Chemical rotation
Pesticide cycling
#12
Which application method involves applying pesticides directly to the soil around the base of plants?
Foliar application
Aerial application
Soil drench
Seed treatment
#13
What is the effect of systemic herbicides on plants?
They disrupt the plant's ability to make chlorophyll.
They cause an immediate burn-down of plant tissue on contact.
They are absorbed and move within the plant to target sites.
They coat the weed's surface, preventing photosynthesis.
#14
In the context of pesticide resistance, what does the term 'mode of action' refer to?
The method by which a pesticide is applied
The specific biochemical interaction through which a pesticide compound causes lethal effect on its target pest
The physical action of a pesticide as it disperses over a target area
The process of mixing different chemicals to enhance potency
#15
Which application technique minimizes pesticide drift?
Using higher spray pressures
Applying pesticides during windy conditions
Spraying at heights far above the target area
Utilizing larger droplet sizes in the spray solution
