Comparative study on the efficiency of dry and green manuring of certain plant leaves against Meloidogyne java']javanica and Rotylenchulus reniformis infecting sunflower

Five different dry and five green plant leaves were tested against Meloidogyne javanica and Rotylenchulus reniformis, as bio-agents in controlling these nematodes infecting sunflower. Data generally, indicated that all the tested manures significantly (P less than or equal to 0.05) reduced the total number of nematodes in root and soil. The best materials were datura dry leaves on M. javanica and lime dry leaves on R. reniformis which gave very good results against nematodes (86.4 and 95.1% female reduction, respectively). Plant growth was significantly (P less than or equal to 0.05) better, in most cases, in shoots, roots and flowering discs weight.
