Types of Pesticides
Organochlorine pesticides
Organochlorine pesticides are a type of synthetic pesticide. They are produced by combining chlorine and carbon. Organochlorine pesticides are some of the most toxic and persistent pesticides. They are effective against a wide variety of pests and have been used for many years. However, they have been banned in many countries due to their harmful effects on the environment and human health.
Organophosphate pesticides
Organophosphate pesticides are a type of synthetic pesticide. They are produced by combining phosphorus and carbon. Organophosphate pesticides are some of the most toxic and persistent pesticides. They are effective against a wide variety of pests and have been used for many years. However, they have been banned in many countries due to their harmful effects on the environment and human health.
Herbicides
Herbicides are a type of pesticide that is used to control weeds. They are effective at killing plants by inhibiting their growth or by causing them to die. Herbicides are used in agriculture and horticulture to improve the yield of crops and to reduce the competition from weeds.
Insecticides
Insecticides are a type of pesticide that is used to control insects. They are effective at killing insects by inhibiting their growth or by causing them to die. Insecticides are used in agriculture and horticulture to improve the yield of crops and to reduce the damage caused by insects.
Fungicides
On the Basis of the Target Group, Pesticides are Classified as:
A) Insecticides
B) Herbicides
C) Fungicides
D) Nematicides
Benefits of Pesticides
Pesticides can help to protect crops from being eaten by insects and other pests. This can help to keep crops healthy and improve yields. Pesticides can also help to protect people and animals from being bitten or poisoned by insects.
Effect of Pesticides
on Soil
Pesticides can have a number of negative effects on soil, including killing beneficial organisms, disrupting the soil food web, and leaching into groundwater.
Use of Pesticides
The use of pesticides is a controversial topic. Some people feel that they are necessary to protect crops from pests, while others believe that they are harmful to the environment and can cause health problems.
Reasons Farmers Use More Pesticides
1. To protect crops from being eaten by pests.
2. To protect crops from being infected with diseases.
3. To increase the yield of crops.
4. To reduce the cost of production.
How is Organic Farming more Effective?
Organic farming is more effective than conventional farming because it does not use synthetic fertilizers, pesticides, or herbicides. This leads to a decrease in soil erosion, and a decrease in water pollution.
