Organic farmers prefer the biological control of disease and pest over the use of chemicals and pesticides because
1.They do not kill the useful and harmful life forms indiscriminately.
2. They are not toxic to human beings.
3. The natural predator-prey relationship and food chains will not get distorted.
4. It is a non-polluting practice.
