Nortica, which contains the bacteria Bacillus firmus, is used to help manage nematodes by creating a living barrier of protection around the root. In trials, research showed that the new product consistently improved root growth, turf quality and turf density. When temperature-activated, the bacteria in Nortica colonize and grow around the root, coating it and preventing damage caused in the J2 larval stage of all major parasitic nematodes, including Sting, Lance and Root-knot, as well as a myriad of others. With its natural composition and through multiple modes of action, Nortica provides consistent, long-lasting nematode protection. Instead of killing nematodes, it acts as competition for access to plant roots and interrupts the signaling responses from plant exudates, while also having a negative effect on nematode eggs and J2 larvae. Available in 35-lb. bags as a 5% wettable powder, it can be applied to Bermudagrass greens, tees, fairways and roughs.
