EVALUATION THE ACTIVITY OF HIRSUTELLA SP. FUNGUS AND THE NEMATICIDE VEROX TO CONTROL ROOT KNOTS NEMATODE MELOIDOGYNE SPP. ON FIG SEEDLINGS

This study was conducted in the plastic house of College Agricultural Engineering Sciences at University Baghdad to evaluate activity Hirsutella sp. fungus and Nematode Verox against Meloidogyne spp. causative agent root knots Fig seedlings. Treatment eggs with 20ml/L 2g/L caused significant inhibition hatching after 3,5 7 d. The number non- were 96.70, 54.00and 29.30 respectively petri plates treated sp., 106.70, 60.00and 46.00 compared 116.70, 111.00and96.00 control. treatment juvenile-2 same periods. 123.30, 114.00and 109.30 sp 20ml/L110.00, 63.00 26.70 seedlings 136.70, 132.00and120.00 control d respectively.
