Detailed explanation-1: -Examples of herbicide-resistant weeds include populations of horseweed (Conyza canadensis (L) Cronq) resistant to N-(phosphonomethyl)glycine (glyphosate). An important question is whether or not these problems represent significant economic issues for future agriculture.
Detailed explanation-2: -Biotechnology can be used to enhance the management of weeds in several ways. Crops have been made resistant to herbicides by inserting transgenes that impart herbicide resistance into the plant genome.
Detailed explanation-3: -A genetically modified organism (GMO) is an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques. From these experiences, scientists have learned that engineering plants to be resistant to herbicides is .
Detailed explanation-4: -glyphosate·resistant soybean. cotton. canola. sugarbeet, anel maize are available to farmers of North Arnerica (although GM-suga1· beet has not been grown).
