Solution
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, glufosinate, sulfonylureas etc. have been successfully developed. Main objective of production/ use of herbicide resisant genectically modified crops is to reduce herbicide accumulation in food articles for health safety.
