Nematicidal effect of some aqueous extracts of botanicals and a commercial bacterial byproduct for biocontrolling root knot nematode, Meloidogyne incognita infecting sugar beet
Journal Title: Scientia Agriculturae - Year 2015, Vol 10, Issue 2
Abstract
Under screen house conditions, certain plant aqueous extracts were added to pots planted with sugar beet (Beta vulgaris L.) inoculated with root knot nematode, Meloidogyne incognita. These tested plants were doum palm, Hyphaene thebaica mashed fruit pomace; pomegranate, Punica granatum mashed fruit peel; stevia, Stevia rebndiana mashed dry leaves, and moringa, Moringa oleifera mashed dry leaves and the commercial byproduct, micronema (containing strains of Serratia sp., Pseudomonas sp., Azotobacter sp., Bacillus circulans and B. thuringiensis) was used. .The tested botanical aqueous extracts and a commercial byproduct reduced root knot nematode according to the tested material as evidenced by the percentages reduction of number of galls, eggmasses and hatched juveniles on roots and in soil of sugar beet plants. Also, plant growth criteria and total soluble sugars (TSS%) were enhanced at different degrees.
