Detailed explanation-1: -Other crops have been engineered to be resistant to specific plant diseases and insect pests, which can make pest control more reliable and effective, and/or can decrease the use of synthetic pesticides. These crop production options can help countries keep pace with demands for food while reducing production costs.
Detailed explanation-2: -Genetically modified crops have been engineered for resistance to pathogens and herbicides and for better nutrient profiles.
Detailed explanation-3: -Genetic engineering facilitates development of insect resistant crops by expressing bacterial -endotoxins and vegetative insecticidal proteins and other plant genes like lectins, protease inhibitors, etc.
Detailed explanation-4: -For GMO crops that are resistant to insect damage, farmers can apply fewer spray pesticides to protect the crops. GMO crops that are tolerant to herbicides help farmers control weeds without damaging the crops.
Detailed explanation-5: -How do you make a crop pest-resistant? Scientists were able to modify the plant’s protein manufacturing system so that it now makes a protein that wasn’t previously present. This carefully selected protein is one that is toxic to certain insects. Basically, they eat it and their stomach ruptures.
