The biggest disadvantage is the potential for creating herbicide-resistant weeds. This is happening right now in the US. Some parts of the country, particularly in the south, have now identified at least 15 separate weed species which are resistant to the herbicide glyphosate (one brand name is Roundup).

Herbicide Tolerant (HT) soybeans are a variety of genetically modified soybean that have been modified to be herbicide resistant.
No unless they have been sprayed with herbicide.
A post-emergent weed killer describes the herbicide that kills dock. The Polygonaceae family member in question responds far less well to pre-emergent herbicides than to post-emergent applications of 2,4-D. The Rumex genus member will react best to controls that remove the perennial weed's branched, large taproot, particularly in the earlier seasons when the size is more abbreviated and less resistant to extraction.
Roundup Ready seeds are genetically modified seeds developed by Monsanto (now part of Bayer) that are engineered to be resistant to glyphosate, the active ingredient in Roundup herbicide. This allows farmers to apply glyphosate to control weeds without harming the crops. The technology is commonly used in various crops, including soybeans, corn, and cotton, enabling more efficient weed management and higher yields. However, the use of Roundup Ready seeds has raised concerns about environmental impact and the development of herbicide-resistant weed species.
There is a selective herbicide that only kills weeds and there is an unselective herbicide which kills everything it comes into contact with and I am not sure about the third one.
Two additional benefits of using herbicide-resistant genetically modified crops are increased crop yields and reduced environmental impact from the use of chemical herbicides.
Crossbow herbicide is guaranteed to kill all weeds and leave grasses intact. Horse tail or Mares tail is a weed which is susceptible to Crossbow herbicide.
To effectively get rid of khaki weed from your garden or lawn, you can manually pull out the weeds, use a hoe to remove them, or apply a selective herbicide specifically designed to target khaki weed. Be sure to follow the instructions on the herbicide label carefully to ensure safe and effective removal.
