"iLeVO, a seed treatment containing Fluopyram recently gained approval for use by the EPA. Those of you who grow vegetables or orchards are likely already familiar with this active ingredient as it is a major component of the Luna fungicide product line. Fluopyram is of the newer group 7 fungicides, which inhibit an essential enzyme in the respiratory pathway, preventing energy production. This results in inhibition of spore germination, germ tube elongation (essential in penetration of plant tissues for many fungi), growth, and sporulation. Interestingly, Fluopyram also has activity against nematodes. This molecule was released in recent years in Honduras for use as a nematicide in bananas, and now it is available as a seed treatment in soybeans. It’s also a component of seed treatments in small grains in Europe, and a few other uses here and there.
From the data I have seen, the best use of this product as a seed treatment is in areas with high levels of Sudden Death Syndrome (SDS) and Soybean Cyst Nematode (SCN) pressure. Data indicates that in these situations, under the proper environmental conditions, you may see yield benefits in the range of 3-10 bu/A. I have also seen some data that indicates that Fluopyram may have activity against root knot nematode as well. There is still some debate on weather this is a true nematicide or simply a nematistatic product. There is some research that indicates that this may be more of a nematastatic product, meaning that it might slow down the nematodes or 'screw them up' for a period of time, allowing the plant to grow larger and better tolerate their future activity."
