Although research into herbicides began in the early 20th century, the first major breakthrough was the result of research conducted in both the United Kingdom and the United States during the Second World War into the potential use of herbicides in war. This is the most common mechanism of herbicide resistance. Competition experiments have shown that herbicide-resistant biotypes of both crops and weeds may have similar competitive abilities as the non-resistant biotypes when they are not sprayed with the herbicide to which they are resistant (Jensen, 1993; Poulsen, 1995; Fredshavn et al. Add any text here or remove it. Since survival largely depended on yield, early farmers would have selected plants based on multiple factors, including their ability to resist disease. This means that less herbicide needs to be used. Whereas, herbicide tolerance is the inherent ability of a species to survive and reproduce after herbicide treatment at a normal use rate.

Glyphosate resistance gene is resistant to glyphosate. Glyphosate herbicide kills plants by blocking the EPSPS enzyme, an enzyme involved in the biosynthesis of aromatic amino acids, vitamins and many secondary plant metabolites. If the same herbicide is applied once again, there will be little seed produced by the susceptible plants, but the resistant plants will continue to set seed. Gene technology has been used to develop herbicide resistant cultivars in cotton, maize, wheat, tobacco, potato, tomato, rapeseed, soybean, flax etc. Disease resistance. As a result of repeatedly using a certain type of herbicide on the same land, many different species of weeds have developed resistance to these chemicals.

Strategies for developing herbicide-tolerant crops We have succeeded in developing crop plants, including soybean and tomatoes, that are highly tolerant to treatment with the widely-used, environmentally-safe and inexpensive herbicide, dicamba. These include genes for resistance to insects, herbicides and viruses. During the Vietnam War, Agent Orange, a mixture of 2,4-D and 2,4,5-T, was used as a defoliant. Herbicide resistance is the inherited ability of an individual plant to survive a herbicide application that would kill a normal population of the same species. That has occurred with some herbicide-resistant canola in Canada. Some farming practices, such as the overuse of herbicides resulting in the excessive eradication of wild plants from farmland have been shown to harm the environment.
