Genetically engineered crop-based agriculture provides a better solution when compared to agrochemical based agriculture as
I : agrochemicals are not easily available
II : farmers often cannot afford to buy agrochemicals in countries like India
III : agrochemicals can have a degrading effect on the environment
IV : agrochemicals increase pest resistance but have no effect on crop production
How many of the above statement(s) are correct?

Solution
The correct option is C 2
Agrochemicals are chemicals such as synthetic fertilisers, pesticides, herbicides, etc that are used in agriculture. Thus, agrochemical based agriculture involves the use of chemicals to increase the crop production.
Genetically engineered crop-based agriculture makes the use of genetically modified crops that have specific foreign genes with desired traits inserted into their genome (entire genetic material of the organism). This provides them with improved characteristics such as better quality, good yield, pest resistance, higher nutritional value, etc.
The use of improved seed varieties, better management practices and agrochemicals such as pesticides and fertilisers, led to the Green Revolution which increased the food supply all over the world.
In developing countries, like India, agrochemicals are easily available in the market but the farmers have no means to afford them as they are quite expensive.
The agrochemicals increase the crop yield but also have a degrading effect on the environment and their increased usage leads to soil and water pollution.
On the contrary, genetically engineered crop - based agriculture makes use of crops that have been genetically modified to develop improved characteristics. Hence they make limited use of agrochemicals for good yield and quality and are more eco-
friendly.
Such crops are also affordable and easily available for farmers in developing countries.
That is why, genetically engineered crop - based agriculture is more advantageous practice than using agrochemicals.
