Which improvements are the most common?

GMOs are created to give plant varieties desirable characteristics, such as resistance to certain pests or herbicides, or healthier profiles. Currently, GM crops have the undermentioned characteristics:

  • Insect resistance. This trait provides farmers with season-long protection against target pests, reduces pesticide use and lowers input costs.
  • Herbicide tolerance. Crops that can tolerate broad-spectrum herbicides, allow farmers to fight weeds by applying herbicides only when needed and participate in no-till methods that preserve soil and prevent erosion.
  • Drought resistance. GM crops that express drought resistance can grow in much drier areas, conserving water and other environmental resources.
  • Disease resistance. Through genetic modification, the Hawaiian papaya industry was able to overcome the papaya ringspot virus, which had the potential to devastate that industry.
  • Increased/enhanced nutritional content. Genetically modified soya beans with healthier oil profiles are used new, heart-healthy soya bean oils.
