Management of the root-knot nematode, Meloidogyne javanica, with non-chemical products on greenhouse-grown tomatoes

In this research, the efficiency of Tricuran-P (Trichoderma harzianum) (۸ kg/ha); Formaycin Gold Px ۲۱% (Pakgostar Com., Iran) for the non-chemical management of the Meloidogyne javanica at the greenhouse level at three concentration rates (۶, ۸, and ۱۰ L/ha); Nitroxin (۵ L/ha); EM (۵ L/ha); Fenamiphos (Nemacur® ۴۰۰CE es) (۱۵ gr/m۲); and Phytohumic (۱۰ L/ha) along with irrigation water was used in comparison with the infected and non-inoculated ones in a completely randomized design at three-time intervals of every three weeks, and the experiment was repeated twice. The results indicated that the fewest J۲ in the soil were found with Nemacur (۵.۵) and Tricuran-P (۵.۸), while the most were in Formycine ۶ (۲۱.۱) and Nitroxin (۲۰.۰). Nemacur (۱۳.۴) and EM (۱۴.۵) had the lowest number of eggs and J۲ in the root, while Formycine ۶ (۱.۹۶) had the highest. At the same time, the lowest number of root galls was in Formaycin ۱۰ (۳.۵) and EM (۳.۷), and the highest ones were in Tricuran-P (۰.۵), Nitroxin (۴.۸), and Phytohumic (۴.۸), respectively. Nemacur also had the lowest number of egg masses (۰.۴). Increasing the concentration of Formaycin led to a decrease in the number of egg masses. Nemacur (۱۱۰) and Tricuran-P (۱۱۶), respectively, had the lowest J۲ reproduction factor in the soil. Cumulatively, as it was shown, Formaycin ۱۰ L/ha can control the RKNs and can compete relatively compared to Fenamiphos (Nemacur) and other relevant bio-fertilizers in this research.
