Removed this bit as it doesn't make any sense without explanation of what e.g. "fops" and "dims" are - if anyone can clarify this, please restore it:

These weeds are controlled by herbicides inhibitors of ACCase (affect lipid synth., i.e. fops and dims herbicides) and inhibitors of ALS (affect branched chain aminoacid synt., i.e. sulfonylureas).

Fops and dims are two types of group A herbicides, which, as stated, inhibit ACCase. Fops are aryloxyphenoxypropinoates and dims are cyclohexanediones. As they're group A herbicides they have a high risk of resistance being developed to them. Probably not particularly relevant. Halften 06:56, 24 September 2006 (UTC)

[edit] Selective removal of wild oats from other grasses/grains

I disagree that it is not relevant.

Currently the article reads "as, being grasses like the crop, they cannot be chemically removed; any herbicide that would kill them would also damage the crop." To a lay person this means they cannot be selectively removed. This is incorrect. While it is perhaps unnescessary to have a lengthy discussion on aryloxyphenoxypropinoates and cyclohexanediones it is important to make it clear that this "weed" can be selectively removed from a field of grain using specific chemicals. From a personal view, the chemical is very expensive (Ca 50€/ha) and current advice is to spray each summer for four years. I understand that the seeds can remain dormant in the ground for up to 10 years. Most farmers here remove it manually by walking up and down the fields and plucking each individual stalk out. I was doing this for much of the week, a heck of a job! A Taxed Mind 20:17, 8 August 2007 (UTC)
