उत्तर
Advantage of using insect-resistant varieties is that it reduces the use of insecticides. This will help in maintaining the soil fertility for a longer period of time, as harmful chemicals present in insecticides will not be added to the soil. It will also reduce the cost of crop production by removing the expenditure of buying insecticides.
