Effect of Molasses Application Alone or Combined with Trichoderma asperellum T-34 on Meloidogyne spp. Management and Soil Microbial Activity in Organic Production Systems

The effect of molasses alone or combined with Trichoderma asperellum T34 Biocontrol® was assessed on Meloidogyne reproduction, disease severity, and density activity soil microorganisms in pot field experiments. Firstly, application at 1 mL m−2 four different textured soils. Secondly, 5, 10, 20, 40 m−2, T34, experiments 10 two effective reducing nematode reproduction the loam but not sandy clay loam, Increasing dosage reduced tomato dry shoot fresh root weights, producing phytotoxicity m−2. severity were between 23% 65% 49% 99%, respectively. In experiment, applied soil. microbial did increase sites where by application, irrespective T34.
