When it comes to weed control, more no-tillers each year are having problems dealing with dandelions. Ohio State University weed scientists Anthony Dobbels, Mark Loux and Jeff Stachler say that dandelions have become much more widespread in Ohio crop production fields over the past 5 years.
An item in the October, 2003, issue on the proper order of tankmixing glyphosate products led to a comment from a No-Till Farmer reader in North Dakota. He informed us that research conducted at North Dakota State indicates that the efficacy of Roundup herbicide is not affected by the order in which it is mixed with water and ammonium sulfate (AMS).
Jason Hill and his father, Fritz, have been in the fight of their lives. The villains are Russian thistle and other weeds that are taking over 3,500 acres of the family's wheat and canola fields in Pendleton, Ore.
If dandelions are causing major problems in any of your no-till fields, the best time to control them for the 2004 cropping season is unfortunately already past.

A survey of Illinois certified crop advisors — including custom applicators, growers and consultants — and related research reveal some dos and don’ts about managing spray drift.
For as little as 20 cents per acre, no-tillers can significantly increase the effectiveness of their post-emergent herbicide applications. The addition of inexpensive ammonium sulfate (AMS) to the tank mix can boost no-till weed control by as much as 41 percent in some cases, according to Bryan Young, a weed scientist at Southern Illinois University.
With fewer new herbicides coming on the market each year, no-tillers are paying much closer attention to developing more effective weed-management plans. As a result, no-tillers are intently studying how various herbicide and tankmix combinations perform in their fields.
During a symposium on glyphosate-resistant weeds held during the annual early winter meeting of the North Central Weed Science Society in St. Louis, Mo., university researchers confirmed the development of glyphosate-resistant waterhemp.
If you're interested in harvesting top yields with Roundup Ready no-till corn and soybeans, it’s likely that you’ll have to add residual herbicides to the weed-control mix.
