(57) A strain of Bacillus lichenlformis (designated 'K357') functions as an insecticide. Surprisingly, application of this single strain of B. licheniformis K-357 reduced nematode hatching and increased nematode mortality in vitro and reduced nematode counts and increased plant vigor and yield in cotton field trials. Nematicidal activity and cotton yield were compared for seed treated with B. licheniformis K-357 to in-furrow application of Aldicarb and Fluopyram, and seed treatment with Abamectin as nematicide. The nematicidal activity of the B. licheniformis K-357 was on par with, and in some cases superior to, that of the chemical treatments. The increases in cotton yield for seed treated with K-357 as nematicide were superior to that of both in-furrow application and seed treatment with the chemical nematicides. Corn seed treated with B. licheniformis K-357 in combination with chemical insecticides and fungicides had decreased root node injury in corn field trials heavily infested with corn rootworm.
