Pesticides and Pest Control Questions

Multiple choice

Which of the following is an advantage of synthetic pesticides?

  1. Increases environmental toxins

  2. Increases crop yields

  3. Increases genetic resistance

  4. Kills all organisms
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The primary goal of using synthetic pesticides in industrial agriculture is to protect crops from pests, thereby increasing total crop yields.

Multiple choice

Which of the following is a disadvantage of synthetic pesticides?

  1. Accelerate genetic resistance

  2. Increase crop yields

  3. Increase profits of farmers

  4. Work fast
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Synthetic pesticides often kill susceptible pests, leaving behind those with natural resistance. These survivors then reproduce, leading to populations that are no longer controlled by the same chemical, which is a major disadvantage of their use.

Multiple choice chemistry metals chemical properties and uses of metals and non-metals introduction to metals physical properties of non-metals

Which of the following non-metal is commonly used as pesticides and photography?

  1. Bromine

  2. Helium

  3. Selenium

  4. Iodine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bromine compounds are effective pesticides, used to prevent pests from attacking stored grain and other produce. Bromine compounds are also used  in photography. Several compounds are used to make the light-sensitive component of a photographic emulsion; without bromine compounds photographs would not capture sufficient light.

Multiple choice biology improvement in food resources manure manures and fertilisers role of organic manures in soil management

_____________ is mainly used to ensure good vegetative growth (leaves, branches, and flowers), giving rise to healthy plants.

  1. Manure

  2. Insecticide

  3. Pesticide

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Manure is used as an organic fertiliser for the better growth of plants. Manure supply nutrients required for the plant growth. It also, improve the fertility of the soil. Horse manure is mainly used as fertilisers in many agricultural fields.

So, the correct option is 'Manure'.

Multiple choice

Common pest control methods include:

  1. Traps

  2. Glue board

  3. ultraviolet fly traps

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Integrated pest management uses a combination of methods, including physical traps, glue boards, and light traps, to control and monitor pest populations.

Multiple choice chemistry water too little to waste pollution of water water pollution planet earth

Choose the correct statement(s).

  1. Aldrin is used as a pesticide.

  2. The maximum permissible limit of nitrate in water is 50 ppm.

  3. The maximum permissible limit of fluoride is 6 ppm.

  4. All of the above
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

A) Aldrin is a pesticide used to control soil insects such as termites, corn rootworm, wireworms, rice water weevil and grasshoppers.
B) The maximum permissible limits for nitrite and nitrate are 10 ppm and 50 ppm respectively.
C) The maximum permissible limit of fluoride is 2 ppm.

Multiple choice zoology sustainable agriculture microbes and farming biopesticide environmental protection

Sporeine is primarily a

  1. Herbicide

  2. Pesticide

  3. Insecticide

  4. Mycoherbicide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Sporeine is a bioinsecticide derived from Bacillus thuringiensis. It is used to suppress the population of many coleoptereious and lepidopterous larvae in Russia, USA and many European countries. It is the trade name given to the commercial product made from Bacillus thuringiensis (Bt). The active ingredient in Bt is a toxic protein, that actually binds to specific sites on the midgut. It is mainly used as an insecticide in agriculture. 
Thus, the correct answer is option C.

Economic threshold injury indicates

  1. Pest density

  2. Pest management

  3. Pest control

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Economic threshold injury is a concept of integrated pest management which denotes the pest density at which management action should be taken to prevent an increasing pest population from reaching the economic injury level.
So, the correct answer is option A.
Multiple choice zoology sustainable agriculture microbes and farming biopesticide environmental protection

Which of the following is an indication of the smallest number of insects that will cause yield losses equal to the insect management costs?

  1. Economic threshold level

  2. Economic injury level

  3. Economic threshold of enzyme activity

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Economic Injury Level (EIL) is defined as the lowest population density of a pest that will cause economic damage.

Biological control of pests is 

  1. Polluting

  2. Highly expensive

  3. Self perpetuating

  4. Toxic
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The biological method is the technique in which there is the use of living microorganisms or its product for the control of pests. This method uses the microbes which act as predators or enemies of the target pest species. The biological control method is often relatively inexpensive because the method uses the microorganisms which can be easily cultured. These are beneficial microorganisms which are used, so they do not contribute the pollution. If biocontrol agents are introduced in any area, survive for multiple years and become self-perpetuating. They will spread over a large area over time and continue to exist for a very longer period. 

Thus, the correct answer is option C.

Latest trend in plant disease control is

  1. Chemical control

  2. Biological control

  3. Good manure and fertilizer

  4. Breeding for disease resistance
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Integrated pest management (IPM) is the programme which particularly focuses on agricultural crop diseases and its management. According to It, the use of biological control agent or other living organisms can control the plant diseases. Biological control is environment-friendly and effective against a broad range of insect pests and relatively easy to adopt.

So, the correct answer is 'Biological control'

Multiple choice zoology sustainable agriculture microbes and farming biopesticide environmental protection

Which of the following process aims at suppressing the pests below economic injury level?

  1. Integrated pests management

  2. Integrated pollution prevention and control

  3. British Pest Control Association (BPCA)

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Integrated pest management is a broad-based approach that integrates practices for economic control of pests. It aims to suppress pest populations below the economic injury level. The process starts with monitoring, which includes inspection and identification, followed by the establishment of economic injury levels. The economic injury levels set the economic threshold level.
So, the correct answer is option A.

Concentration of insecticide in the animals of a species is known as

  1. Eutrophication

  2. Bioconcentration

  3. Bioindicator

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bioconcentration is the process of ingestion and retention of the chemical substance in an organism. It mainly occurs in the aquatic organism by the exposure of waterborne chemicals.
