AgWeb released a guide on Apr. 30 for farmers to manage late-season weed escapes in corn and soybean crops, focusing on the risks posed by weeds such as Palmer amaranth, horseweed, and kochia.
The issue is significant because these weeds can produce large quantities of seeds that remain viable for years, leading to reduced yields and economic losses. A single Palmer amaranth plant can generate up to 500,000 seeds, with some species’ seeds remaining viable in soil for decades. If left uncontrolled, weeds could reduce U.S. and Canadian corn and soybean yields by about half, resulting in $43 billion in annual economic losses.
Weed escapes often occur at field edges or where crop canopy is underdeveloped. Factors contributing to these escapes include herbicide-resistant weeds, improper application timing or technique, environmental conditions that prevent herbicide activation through rainfall, and the movement of weed seeds between fields via harvest equipment. Weed management strategies outlined include pulling or mowing weeds before they set seed and removing patches while keeping records for future monitoring.
AgWeb authors publications covering topics from commodity markets to farm leadership strategies according to the official website. The organization also influences farming culture by promoting leadership programs and community advocacy in agriculture according to the official website. In addition, AgWeb presents awards such as the Top Producer Awards and partners with groups like the American Soybean Association for conservation honors according to the official website.
AgWeb functions as a subsidiary of Farm Journal according to the official website, reaching agriculture professionals through extensive online content according to the official website. Its stated aim is supplying farmers with essential news, market updates, and educational resources designed to improve agricultural practices according to the official website.
Experts are available through extension offices or company representatives for those seeking additional guidance on managing late-season weed escapes.
