The skinny on a big problem…weeds
Matthew Ryan, Stacy Duh, Dave Wilson and Paul Hepperly
NEW! October 18, readers respond to a web-based survey about weed management and tell how they deal with their weeds.

Choosing cover crops for
no-till organic soybeans
The more biomass the better for weed suppression—but you do have to be able to plant through the stuff. Rodale Institute researchers continue to work the kinks out of the no-till fields. Above: One advantage of no-till, they've discovered, is the weeds are confined mainly to the rows. MORE>

Banking on BARC

July 15, 2005: Thanks in part to the work of weed ecologist John Teasdale, left, the USDA Agricultural Research Service's oldest experiment station is doing some of the agency's most forward-looking work. MORE>

Weed management research
at The Rodale Institute:

Part 2: Identifying weed-tolerant corn and soybean varieties For the past three seasons, researchers here at The Rodale Institute have been testing off-the-shelf organic corn and soybean varietiesto find those whose yields are least affected by weed pressure.

Part 1: Can organic crops tolerate more weeds? Ongoing research at The Rodale Institute examines the apparent ability of organic crops to maintain yields in the presence of substantial weed pressure. Above: Conventional (left) and organic (right) corn in the FST.

Look, Ma! No Weeds
A 3-Part Series on Early Season Weed Control
By Klaas and Mary-Howell Martens (with help from Peter Martens)

Part 1: The basics of effective tillage techniques
Posted January 27, 2005: Knowing just when to use just the right tool for just the right weed is critical to early season weed control.

Part 2: Blind cultivation
Posted February 10, 2005: Get weeds before they become established and the battle is nearly won. Above: Lely finger

Part 3: In-row cultivation
Posted March 17, 2005: It’s as much about the technique—and being able to adapt to fickle weather—as it is about the tools

Use tadpole shrimps to control weeds in transplanted paddy rice

August 2002: These tiny crustaceans occur naturally if you know how to promote the right conditions in your paddy fields.

Beating weeds naturally
Posted Jan. 9, 2004: When it comes to weed suppression without pesticides or herbicides, understanding growth cycles and plant habits is key, and a lot of little actions now can add up to a whole lot of control later.

The basics of biological weed control
Posted March 21, 2003: Gary Zimmer, author of The Biological Farmer, laid out the ABCs of controlling weeds through building soil, rotating crops and cultivation before a standing room only crowd at the Upper Midwest Organic Conference in late February
