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).

- Can't keep seed over -- If you plant seed produced by hybrid plants the following year, you will not get the same kind of plant.
