The big advantage for farmers in making crops resistant to herbicides is that certain herbicides could then be used to remove all weeds in one go meaning less spraying. Normally herbicides would damage the crops as much as the weeds so its of huge benefit if they are resistant.

∙ 6y agoThe years since the 1940s describe the timeline for crops becoming resistant to herbicides. Research indicates that herbicide resistance is not a new phenomenon. Farm crop and garden edible and ornamental herbicide resistance spurs science to invent and re-examine pest controls for going on 70 years, as of 2018.

How are GM food crops produced?
GM crops are produced much like other crops, except that many that are grown have been genetically engineered to be resistant to herbicides or to produce an insecticide in the plant itself.
Is GM food the way to go if you wish to solve the world's food shortage problems?
Some say it is and others say it is not. Considering that crops engineered to be resistant to herbicides appear to lose that resistance over time, leading to crops that are resistant to other herbicides being created, as well as possible negative effects on species in the soil, and weeds developing super resistance, the pollution issues may outweigh any good effects the crops may have had.
What has the author Vijay K Nandula written?

Many crops such as tomatoes and corn are now routinely genetically manipulated to become more resistant to disease and herbicides What is one disadvantage of this genetic resistance?
The genes may be transferred to weeds during pollination.
What are the uses of herbicides?
herbicides are used to destroy weeds or fungi which may destroy or cause the crops to get diseases.
What is one of the problems with improving the food supply by genetically engineering better crops?
Some crops are genetically engineered to resist certain herbicides, which means the herbicides they are engineered to be resistant to can withstand having the herbicide sprayed directly on the crop. A known problem with these crops is that after a number of years, more herbicide is needed to control weeds. Because of this, more herbicides are sprayed on the crops and end up in foods. The safe limit for glyphosate (Round-up) in foods has been raised by the EPA in the United States and the use of Glyposate on crops has doubled in the years since Glyphosate resistant crops have been commercially grown. Other crops are genetically engineered to produce an insecticide in the plant itself. Though the insecticide is suppose to target certain insects, two concerns are that non-targeted insects are being killed and people's and animal's health may be affected when those crops are eaten. Generally, some believe horizontal transfer of the engineered genes in the crops may occur. Another problem that has occurred is weeds have developed resistance to the herbicides crops have been engineered to resist. The absence of long-term studies concerns others, making some feel that they are the long-term study.
Which career combines DNA technology and agriculture?
Biotechnology combines DNA technology and agriculture by using genetic engineering to create crops with specific traits. Currently, most are modified to be resistant to herbicides or to produce an insecticide in the plant itself.
Should pesticides and herbicides be used on organically grown crops?
Only those compounds which have been specifically approved for organic use.(By the way, herbicides are pesticides.)
What are agri-chemicals?
Chemicals like herbicides, pesticides and fungicides, that are used on crops on farms.
How is DNA used in agriculture?
The role of DNA in agriculture arises with the use of genetically modified organisms, generally the product of the Monsanto corporation. Typically, crops are engineered to be resistant to herbicides. A strain of rice has been created, golden rice, which is a source of vitamin A.
What are geniticaly modified crops?
Genetically modified crops are crops with plants that have been genetically altered in order to increase the yield of the crop. For example, the plant may have been genetically altered to become bigger or more resistant to bugs.
What are the benefits of GMO production?
One benefit of GMO production was said to be that less herbicides would be used on them. This; however, has not proved to be the case after they were used for several years. After years of using them, it appears that the use of glyphosate has doubled due to the use of glyphosate resistant crops.
