NEMASTRIKE™ and Parasitic Nematodes

Nemastrike_by_AcceleronNematodes can be responsible for yield loss in agronomic crops. In corn it is estimated that 10% of a crop’s potential yield is lost to nematode damage. 80% of the corn acres in the United States are infested with nematodes.

NEMASTRIKE™ is a new technology to combat these microscopic roundworms. The chemistry behind this technology is a new class of nematicides with a novel mode of action, targeting only plant parasitic roundworms.


  • 3-years of research in corn indicates an average 7 bushel advantage over competitive nematode protection products in 73% of the comparisons
  • A 75 day active period in the root zone provides nematode control through a second generation
  • Low water solubility and low soil movement keeps the active formulation in the root zone
  • When Acceleron®/NemaStrike™ seed treatment is purchased from LG Seeds; a 100% stand guarantee is included.


Parasitic nematodes are very small roundworms that infect the roots of crops and can cause potential yield loss in corn, soybeans and cotton. This loss is estimated to be over 10% across these valuable agronomic crops, according to a nationwide loss estimate by the University of California. Approximately 80% of the Corn Belt in the United States is infested with nematodes. The most well-known of these microscopic roundworms is the Soybean Cyst Nematode (SCN). Often producers associate nematodes with sandy soils. This is not necessarily the case. Many nematodes (there are over 50 species identified as corn nematodes) thrive in all soil types.

Much of the damage caused by nematodes is frequently diagnosed as stress – drought, herbicide and/or disease stress. Yellowing of the leaves, wilting of the plants stunted growth, are all symptoms exhibited by these stresses. The same symptoms can often occur when high populations of nematodes are found. Nematodes rob the plant of vital nutrients and water. By feeding in the roots, nematodes also open the plant to infections by bacteria and fungi, along with having the ability to transmit viruses. The effects of nematode feeding results in poor performance and can lead to potential yield loss.

NemaStrike™ technology aids in reducing the plant stress caused by nematodes and reduces the yield loss associated with nematode feeding. This new nematicide chemistry affects only plant parasitic nematodes and provides control of Lesion, Sting, Needle, Stubby Root, Lance, Reniform, Root Knot, Soybean Cyst nematodes, and many others.

Individual results will vary based on the nematode pressure in each field
