Channel Field Check Up Managing An Invisible Threat To Soybean Yields
JOE BUNCK
LUBBOCK, TEXAS
The soybean cyst nematode is generally considered the pest that poses the most risk to soybeans in the United States. The U.S. EPA has stated that plant parasitic nematodes cause an estimated 14 percent loss in agriculture production worldwide, with $80-$100 billion worth of global crop losses every year.1
Nematodes infect the roots of the plant, taking away its nutrients and water form the inside. Despite how abundant they are, most nematodes are undetectable by the human eye.
The presence of nematodes may vary based on soil type, environmental conditions and the presence or absence of actively growing host plants. Many species thrive in sandy soils, though soybean nematodes can be found almost anywhere, including heavier soils. Under favorable conditions, most parasitic nematodes can complete their life cycle (egg, four juvenile stages, egg-producing adult) in about one month, and may complete four or more life cycles in one growing season.2 Mature females of some species can produce hundreds of eggs, leading to rapid growth of population densities.
In May, Monsanto Company announced that the U.S. EPA approval of a novel Nematicide branded NemaStrike™ Technology. Expected to be available in most states beginning in 2018, NemaStrike™ Technology will provide broad-spectrum control of plant parasitic nematodes and consistent yield protection performance in corn, soybeans and cotton. Over three years of testing in all soil types and levels of pressure, products with NemaStrike™ Technology showed a yield benefit of in soybeans (3 Bu/A in 113 trials); corn, (7 Bu/A in 100 trials); and in cotton (80/lbs Lint/A in 51 trials).3
Acceleron® Seed Applied Solutions with NemaStrike™ Technology provide a novel mode of action that stays in the root zone, where nematodes attack, for up to 75 days. NemaStrike™ Technology is designed to provide broad-spectrum control of plant parasitic nematodes and consistent yield protection performance in corn, soybeans and cotton.
The local Channel Seedsman can provide product recommendations, based on specific field conditions, that are tolerant to nematodes. To protect the potential of those products, consider Acceleron® Seed Applied Solutions with NemaStrike™ Technology.

3 3-Year Average Yield Protection Advantage over control, across all locations and thresholds, N=213 Trials (2014, 2015, 2016) (AR, GA, IA, IL, IN, KS, KY, MD, MI, MN, MO, MS, NC, ND, NE, OH, SC, SD, TN, TX, VA, WI) Results will vary based on nematode pressure in each field.
Individual results may vary, and performance may vary from location to location and from year to year. This result may not be an indicator of results you may obtain as local growing, soil and weather conditions may vary. Growers should evaluate data from multiple locations and years whenever possible.
