Nemasys® G Beneficial Nematodes

Nemasys G Heterorhabditis bacteriophora beneficial nematodes help provide biological control of larval, or white grub, stages of European chafers, Oriental beetles and Japanese beetles.

Beneficial nematodes are microscopic worms that attack and kill targeted insects, without affecting any other organisms. Within the infected insect, the beneficial nematodes continually reproduce and then spread out for long-term control.
