The most destructive adversary to impact cotton production since the boll weevil is costing cotton farmers potential yields and profit.
Farmers have to work diligently to keep up with the herbicide-resistant weed, technically known as Palmer amaranth.

North Carolina organic wheat producers who face challenges in controlling stubborn weeds, specifically Italian ryegrass, may soon be able to choose from varieties that suppress those weed populations.
North Carolina State University graduate student Margaret Worthington is studying 60 soft red winter wheat cultivars from public and private breeding programs for morphological characteristics and allelopathic traits that would help the wheat plants out-compete Italian ryegrass. The research, “Breeding Wheat for Increased Weed-Suppressive Ability Against Italian Ryegrass (GS12-115),” is being funded by a two-year, $10,952 Southern Sustainable Agriculture Research and Education (SSARE) Graduate Student Grant.

Thomas Jefferson and George Washington sang the praises of buckwheat. Today, the broadleaf grain is gaining new popularity as a powerful weed-suppressing cover crop because of its quick establishment and dense growth: In the Northeast, vegetable farmers are rediscovering how to manage buckwheat effectively, thanks to Cornell University research that demonstrated a well-established stand of buckwheat eliminated 98 percent of summer weeds.

Many vegetable farmers want to improve soil quality, but because they operate in a competitive, rotation-intensive environment, any soil-building practice they are likely to adopt needs to be backed by solid data.

Proactive herbicide weed control for lawns is the key to remaining weed-free when the turf turns green in the spring, a Texas A&M AgriLife Extension Service specialist said.

There is little money left for hoe crews and no chemical options remain. Many of these fields will be combined, surely spreading the weed — not only in these fields but in others that the combine goes into later. I do not blame you for cutting these beans; there is money out there. Most fields are clean enough and were clean enough long enough that yield may not even be affected.
For more than half a century, producers in northeast Mississippi have met annually with Extension and research leaders to discuss ways to improve production and efficiency in the region.
Specialists with the University of Kentucky Wheat Science Group will present timely information related to the 2012 wheat production year during their winter meeting from 9 a.m. until 3 p.m. CST Jan. 10 at the James E. Bruce Convention Center in Hopkinsville.
Three essential points for effective weed control — start with a clean field, overlap residual herbicides and manage the soil seed bank — were the recurring theme during a July 21 field day at the University of Arkansas Division of Agriculture’s Northeast Research and Extension Center.
