Main objective of production/use of herbicide resistant GM crops is to

  • eliminate weeds from the field without the use of manual labour

  • eliminate weeds from the field without the use of herbicides

  • encourage eco- friendly herbicides

  • reduce herbicide accumulation in food particles for health safety


D.

reduce herbicide accumulation in food particles for health safety

The chemical substances, which are sued to kill or repel pest are called pesticides. The pesticides, which are used to destroy weeds are called herbicides. Herbicides are used in agriculture to control the weeds. They inhibit plant growth by blocking the biosynthesis of amino acids or photosynthetic activities of plants. Transgenic plants resistant to several herbicides. eg, glyphosate, gluphsinate, sulphonylireas etc, have been successfully developed the main objective of production /use of herbicide-resistant genetically modified crops is to reduce herbicide accumulation in food articles for health safety.
