Securing enough nutritious food for growing populations is a big challenge. Corvus® herbicide offers an innovative solution.
With the world's population projected to reach more than 9 billion by 2050, the land available for farming on our planet will need to be more productive than ever. But the challenges facing agricultural crop production aren't limited to demographic issues. One of the greatest threats to agriculture is coming from the fields themselves. The rapid evolution of weed resistance is mounting huge challenges for developed nations.
Population growth is increasing demands on agriculture and decreasing the availability of arable acreage, but improving the productivity of farmland could provide a near-term solution. Stephen Powles, a grain grower who is also professor of plant biology at the University of Western Australia, predicts the U.S. will soon take Australia's place as the number one country in the world for weed resistance to herbicides. The heavy use of glyphosate in the Corn, Soybean and Cotton Belts is a leading cause of increased resistance problems. "In my view glyphosate is a one-in-a-hundred-year discovery that is as important for global food production as penicillin is for global human health," Powles says. But it's "failing in corn, soybean and cotton crops in the American Midwest and South because of massive overuse." He says careful, calculated use of the herbicide is now critical to preserve it for future use.

Battling Back Against Resistance
Knowing its customers are battling against multiple threats to crop production, Bayer CropScience is working hard to craft innovative solutions to combat weeds and weed resistance problems in corn. Nearly 50 percent of the world’s corn comes from the United States. A leading Bayer CropScience corn herbicide, Corvus® herbicide, delivers a range of herbicidal benefits.
Corvus one-pass herbicide combines two modes of action—an ACCase inhibitor with a HPPD enzyme inhibitor—and requires just 5.6 fl oz/A to control more than 50 grass and broadleaf weeds. A pre-emergence corn herbicide, Corvus provides broad-spectrum control of more than 50 grass and broadleaf leaves, including weeds resistant to glyphosate-, ALS-, PPO- and triazine-based herbicides. Notorious resistant weeds include Palmer amaranth, or pigweed, and waterhemp, among others.
The active ingredients within Corvus translocate through the roots and shoots of weeds, inhibiting the photosynthetic process, providing rapid burndown and long-lasting residual control. But Corvus also provides excellent crop safety, protecting the plant’s metabolic systems from herbicidal action.
Herbicides are by no means the only way to address resistant weeds and the challenges of agricultural productivity. Rotating crops, fields, herbicide-tolerant traits and modes of action will be key in the continuing fight to battle threats like weed resistance, maximize productivity and feed a constantly growing world.
