Farmers do not have to use harsh chemicals to save their crops.
Step-by-step explanation:
A pest can be described as an animal particularly an insect which damages plants or crops. Formerly, farmers had to use chemicals to kill insects which attacked the crops. These chemicals would affect the plants also. The insects also developed resistance for these chemicals after a short period of time.
Now, the techniques of biotechnology have made it possible to make crops which have pesticide resistant genes in them. These crops are hence not affected by the pesticides.
