Concept area : Scientific method of pest control
Activity 2
Analyse the reading card and answer the questions given below.
As the pests acquire resistance against chemical pesticides, the quantity of chemical
pesticides has to be increased. Excessive application of chemical pesticides cause
many environmental and health issues.
Adopting integrated pest managemant methods help to control pests without disturbing
the environment and health. The basic principle of Integrated Pest Management is not
the destruction of pests totally, instead it tries to prevent the multiplication of pests and
limit their number without loss of crop . This is done by using bio pesticides, natural
enemies of the pests, mechanical pest control methods etc . Here the use of chemical
pesticides has been minimized.
A conversation between two farmers is given below. Analyse it and answer the questions.
Farmer 1 - I use Chemical pesticides for pest control.
Farmer 2 - I depends natural enemies of pests instead.
i) Among them whose pest control method is suitable to the environment. Why?
ii) What are the problems created by the pest control method of the other farmer ?
Answers
Answer:
Pesticides are substances that control various types of pests, such as weeds, harmful insects, and disease-causing organisms like bacteria and fungi. Pesticides oftentimes are the most effective and efficient pest control tools available
Resistance to pesticides is a serious, and growing, problem. Worldwide, more than 600 species of pests have developed some level of pesticide resistance. If resistance to a particular pesticide or “family” of pesticides evolves, these products can no longer be effectively used thereby reducing the options available for pest management. With few new pesticides (new modes of action) in the development pipeline, pesticide users must do all they can to extend the useful life of the products currently available.
This module will explain how resistance develops, the factors that contribute to it, and how it can be avoided or managed.
- Understanding Resistance — What is pesticide resistance?
- Preventing Resistance — Ways to stop the spread of resistance.
- Herbicide Resistance — Understanding resistance in weeds.
- Insecticide Resistance — Understanding resistance in insects and insect-like organisms.
- Fungicide Resistance — Understanding resistance in fungus and other plant pathogens.
