The attached map depicts the change in tons of rice production per acre of farmland between the years 1970 and 2015.

Explanation:  

• Pesticides refer to the chemicals used to eradicate pests.
• A pesticide is typically a chemical or biological substance that deters, incapacitates, or kills pests, such as a virus, bacterium, antimicrobial, or disinfectant.

• It is mainly used to eliminate or control a variety of agricultural pests that can damage or destroy crops and livestock and limit farm productivity.

• The most commonly applied pesticides include insecticides to kill insects, herbicides to kill weeds, rodenticides to kill rodents, and fungicides to control fungi, mould, and mildew.

• They are mainly used for the below-mentioned beneficiary purposes:

1. Improving crop yield & productivity.

2. Protection of crop losses/yield reduction.

3. Vector disease control.

4. Improved Quality of food

• The use of pesticides increased the amount of rice produced from 1.0 to 1.6 tons in the black region on the map.

• The use of pesticides increased the amount of rice produced in the grey area from 0.5 tons to 1.0 tons.
