Abstract
The effect of commercial biocontrol products viz. Nemakill, Nemaless, Micronema as well as an Egyptian entomopathogenic nematode (EPN) strain of Heterorhabditis bacteriophora-infective juveniles (IJs) within either cadavers of Galleria mellonella last instar larvae or EPN-IJs in water suspension, compared to chemical nematicides of Nema Plus Zero and Oxamyl on Meloidogyne incognita developmental parameters, strawberry growth and yield and rhizosphere microbial community were determined in two separated field experiments. Six months after strawberry transplanting, 30-88% reduction in nematode juveniles (J2) in soil was achieved by Nemakill, Nemaless and Micronema, while reduction range was 37-64% by EPNs compared to 64-73%, by chemicals. The commercial products followed by EPNs significantly reduced the numbers of M. incognita-J2, galls, and egg masses in strawberry roots. All treatments enhanced strawberry growth and yield parameters. Nemakill followed by EPNs in water and within insect gave best fruit yield of strawberry cv. Festival. Nemaless followed by Nemakill and Micronema gave best fruit yield of strawberry cv. Fertona. Effect of tested treatments on rhizosphere microbial community and mycoflora frequency in treated strawberry plants was presented and discussed.
