INFLUENCE OF THE GREEN ALGAE Chlorella (Chlorella vulgaris) ON THE ROOT-KNOT NEMATODE (Meloidogyne arenaria) UNDER GREENHOUSE CONDITION

摘要

The green and blue-green algae such as Chlorella, AFA, Spirulina refer to a group of powerful phytoprotectors. Chlorella, the object of this study, is described with the presence of specific growing factor - 'growing factor Chlorella' which is proved as a very potent immunostimulator in living organisms. Up to now there were no data in the literature related to our experiment with Chlorella on sick plants of soil pathogens (ncmatodes). The aim of this preliminary study is to investigate the influence of Chlorella on root-knot nematode (M. arenaria) in tomato growing under greenhouse conditions. The results indicate clear suppressing effect on the hatching of larvae and almost full reducing galls forming on the root. Simultaneously it was obvious stimulating on the growth and development of the infected and treated with Chlorella tomato plants approximate uninfected treated control.
