Influence of Green Algae Chlorella vulgaris on Infested with Xiphinema index Grape Seedlings

Tatyana Bileva

Plant-parasitic nematodes are considered a major pest in grape growing countries. The present study was conducted during June-November 2007. The aim of the pot experiments was to establish the impact of dry extract of Chlorella vulgaris on the ungrafted grapevine seedlings cv.“Palieri” infested with root ectoparasite Xiphinema index. Different dosages of Chlorella (0.5, 1.0, 2,0 g per plant/pot) were investigated. The results show a decrease in the number of X. index in the variants treated with 1g Chlorella. There has been a positive effect on the growth characteristics of the test plants at the same concentrations. The green algae Chlorella vulgaris as a powerful phytoprotector have strong stimulating effect on the plant growth.
