There are several options when it comes to choosing cover crops. You need to know the conditions of your farm and what goals you want to achieve. Here are some details on a few popular cover crops to help you
More than 150 farmers and agribusiness professionals took part in Weeds Week events around the state this summer. The 2016 Weeds Week, held July 18-22, was the second year
Knotweed will not take over British Columbia if Matthew Strelau has anything to say about it. The Surrey resident is studying whether the invasive bohemian knotweed plant will build up a resistance to the herbicide used to treat it.
This online course covers topics in herbicide classification, herbicide mode of action, and resistance mechanisms. The goals of the course are: to understand the fundamental physiology, biochemistry, and molecular biology
If weeds were allowed to grow with no control measures, about half of corn and soybean crops across the United States and Canada would be lost, costing growers about $43 billion annually, says a team of researchers.
There is a troubling discrepancy between the large number of harmful invasive plant species and the number of invasive plant species that are actually regulated. At the federal level, the USDA’s Animal and Plant Health Inspection service (APHIS) includes
Like clockwork, Mid-South cotton growers know that pigweed escapes will begin to pop up in their fields by mid-July. In addition to being prolific seed producers, the pesky weed can also feature resistance to several types of herbicides
Will Mid-South producers soon adopt widely used Australian techniques aimed to keep resistant weed seed out of fields? Steve Powles, a leading resistant weed specialist in the world, predicts that is exactly what will happen.
Wet weather in the forecast will likely make for a narrow window to get these fields sprayed timely. As a result, there is likely to be some good size Palmer amaranth up in some corn fields by the time we can get back into spray.
Believe it or not, tumbleweeds—so strongly associated with wide-open expanses of the western United States—are actually weedy invaders from other continents. The most iconic and successful of these, the Russian thistle (Salsola tragus), came to America
Two decades of research and development into destroying weed seed has taken a giant step forward with the release of a harvester integrated version of the Harrington seed destructor.
Giant two-metre-high tumbleweeds have inundated a small community in Victoria's north-east, creating havoc and blanketing homes, cars and driveways.
