Abstract

         This study, conducted at the University of Baghdad, College of Agricultural Sciences and Engineering, Department of Plant Protection, aimed to evaluate both chemical and biological factors in inhibiting the hatching of Meloidogyne spp. nematode eggs using ascorbic acid and potassium phosphate at three different concentrations (50, 30, 10 mM). The study aimed to select the effective concentration that significantly impacts the vitality of nematode eggs and juveniles. Additionally, some earthworm-derived products were tested in both solid and liquid states, comparing the results with a commercial compost powder.

The results indicated that the vermicompost produced in this study (liquid and dry) exhibited the highest inhibition percentage for Meloidogyne spp. egg hatching at concentrations of 0.7 and 0.07 gm, respectively. The inhibition percentage reached 100% after 72 hours under laboratory conditions.
