Acceleron® Seed Applied Solutions with NemaStrike™ Technology for Control of Nematodes

​​Through the years, parasitic nematodes have been the cause for yield losses of greater than 10% in each of the three core United States crops: corn, soybean, and cotton.1 Microscopic nematodes pierce plant roots, which can help facilitate plant bacterial, fungal, and viral infections.

Nematode damage is frequently underestimated and misattributed to stresses associated with drought, fertility, chemical injury, and disease. Symptoms may not be visible or appear as wilting, yellowing, or stunting. The presence of nematode species can vary based on environmental conditions, soil type, and the presence or absence of actively growing plants that support their life cycle. Yield loss attributed to nematodes has been estimated at 10.2% for corn, 10.6% in soybean, and 10.7% in cotton.1

Nematodes are able to enter fields through soil movement including the wind, shovels, boots, farm machinery, and animals. It has been estimated through sampling that over 80% of U.S. corn acres are infested with at least one species of nematode.2

Crop protection has primarily been limited to crop rotation, use of resistant soybean products, and available nematicides. However, the EPA recently approved the use of NemaStrike™ Technology, a seed treatment technology that provides broad-spectrum nematode control for soybean (Figure 1), corn (Figure 2), and cotton crops. Some of the nematodes controlled include soybean cyst, root knot, lesion, lance, reniform, sting, and needle.

With a novel mode of action, low water solubility, and new chemistry (Tioxazafen), NemaStrike™ Technology defends crops from the start and stays in the root zone as plants grow for up to 75 days. In numerous field trials over 3 years, the technology has helped to protect the average yields of corn by 7 bu/acre (100 trials), soybean by 3 bu/acre (113 trials), and cotton by 80 lbs lint/acre (51 trials).3 Performance results will vary based on nematode pressure.
