Research on biorationals for control of nematodes

Nematodes are causing increasing problems on golf course greens (read more here), and, with the cancellation of Nemacur (fenamiphos), there are few effective products available for their control. For this reason, we conducted a field study on the efficacy of several different biological control agents for control of nematodes — particularly the root knot nematode, Meloidogyne. We found that:

- An experimental product based on the beneficial bacterium Bacillus firmus had the best results, causing significant reductions in root knot…
