Management of Meloidogyne incognita on tomato by root-dip treatment in culture filtrate of the blue-green alga, Microcoleus vaginatus.

摘要: The nematicidal potential of culture filtrates the blue-green alga, Microcoleus vaginatus (Cyanobacterium) was tested against Meloidogyne incognita on tomato in pots under greenhouse conditions. Prior to transplantation seedling, roots were dipped different concentrations (0.2%, 0.5%, 1%, 2%, 10%, 50% and 100%) filtrate M. for 30 min. Root-dip treatment reduced root galling final population increased vegetative growth plants root-mass production compared with control. beneficial effect root-dip increase concentration filtrate. Root nematode populations by 65.9% 97.5%, respectively when treated at highest concentration.
