New golf course nematicides
New nematicides are filling the gap left in the toolboxes of superintendents who relied on Nemacur, but a single product will likely not be sufficient to replace the old standby.

Content: These three nematicides along with several others released since 2010 provide multiple weapons in the arsenal against nematodes. However, for many, the question remains: Do these new nematicides work as well as Nemacur? To answer this, we need to review a little about Nemacur, the types of nematodes that damage turf, and preliminary research data on the effectiveness of these new nematicides. We will then evaluate the properties of Divanem, Indemnify and Nimitz Pro G, and their relative efficacy on the four nematode genera that are currently the most problematic on golf course turf in the United States: sting, lance, root-knot and Pacific shoot-gall nematodes. The active ingredient in Nemacur was fenamiphos, an organophosphate pesticide that affects the nervous system. Because all nematodes have similar nervous systems, they were all impacted by Nemacur. Further, fenamiphos has both contact and systemic activity and, therefore, is effective on nematodes in soil and, to some degree, inside roots. Nemacur was a very versatile treatment;
