A few sturdy species of weed are proving to be a fair fight for Roundup weed killer. At least 10 weed species are withstanding the blow of Roundup in at least 22 states.  Some of the species, such as Palmer amaranth in Arkansas and water hemp and marestail in Illinois, grow fast and big, producing tens of thousands of seeds. "It's getting to be a big deal," Mike Plumer told the Associated Press (AP). Plumer, a 61-year-old farmer and University of Illinois agronomist who grows soybeans...

Using herbicides to sterilize rather than to kill weedy grasses might be a more economical and environmentally sound weed control strategy, according to a study by Agricultural Research Service (ARS) scientists and a cooperator. Rangeland ecologist Matt Rinella at the ARS Fort Keogh Livestock and Range Research Laboratory in Miles City, Mont., conducted the study with colleagues at Miles City and Robert Masters with Dow AgroSciences LLC, in Indianapolis, Ind. Exotic annual grasses such as...

Foxtail millet, cowpea examined in conservation tillage experiments Conservation tillage encompasses a range of techniques for establishing crops in the previous crop's residues, which are purposely left on the soil surface. The principal benefits of conservation tillage are improved water conservation and the reduction of soil erosion; additional benefits can include reduced fuel consumption, planting and harvesting flexibility, and reduced labor requirements. A new study published in...

Crop and herbicide use history are more critical to herbicide efficacy and environmental safety than the timing and amount of irrigation water used, according to Agricultural Research Service (ARS) scientists. ARS plant physiologists Dale Shaner and Lori Wiles made this discovery from ongoing experiments on two irrigated fields at Colorado State University (CSU) at Fort Collins, Colo. Shaner and Wiles work in the ARS Water Management Research Unit at Fort Collins. In collaboration with CSU...

In what amounted to a kind of census of sweet corn grown for processing, three years of data from 175 fields in Illinois, Wisconsin, and Minnesota shed light on what works and what doesn't. Along with identifying the most troublesome weeds, the results also revealed some of the more complicated relationships among factors influencing both weed control and sweet corn yield in the Midwest. "Rather than a typical controlled field experiment, this was a large scale approach. We wanted to find out...

2-year study shows pine needle mulch most effective Research scientists at Nova Scotia Agricultural College have been working steadily to find effective organic methods to control weeds in cultivated blueberry crops. One resulting study, published in a recent issue of the ASHS journal HortScience, reported on the efficacy of three organic mulches used on highbush blueberry (HBB) produced under organic production practices. The research team determined that the major factor influencing weed...

Michigan State University scientists say they've found pesticide-free mulched maple and oak leaves can reduce the number of dandelions on Kentucky bluegrass. The objectives of our research were to quantify the effectiveness of four maple and one oak species leaf mulch as an organic broadleaf weed control method in an established Kentucky bluegrass turfgrass stand, then to identify specific maple species that provide effective broadleaf weed control, said Alexander Kowalewski of the...

Cover crops add fertility to the soil, control weeds and pests as well as control diseases that can be otherwise found in untreated soil. Cover crops increases the organic matter levels in the soil which only enhances the structure of the soil as well as increase the capacity for...
