Abstract

In this research, the efficiency of Tricuran-P (Trichoderma harzianum) (8 kg/ha); Formaycin Gold Px 21% (Pakgostar Com., Iran) for the non-chemical management of the Meloidogyne javanica at the greenhouse level at three concentration rates (6, 8, and 10 L/ha); Nitroxin (5 L/ha); EM (5 L/ha); Fenamiphos (Nemacur® 400CE es) (15 gr/m2); and Phytohumic (10 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 J2 in the soil were found with Nemacur (5.5) and Tricuran-P (5.8), while the most were in Formycine 6 (21.1) and Nitroxin (20.0). Nemacur (13.4) and EM (14.5) had the lowest number of eggs and J2 in the root, while Formycine 6 (1.96) had the highest. At the same time, the lowest number of root galls was in Formaycin 10 (3.5) and EM (3.7), and the highest ones were in Tricuran-P (0.5), Nitroxin (4.8), and Phytohumic (4.8), respectively. Nemacur also had the lowest number of egg masses (0.4). Increasing the concentration of Formaycin led to a decrease in the number of egg masses. Nemacur (110) and Tricuran-P (116), respectively, had the lowest J2 reproduction factor in the soil. Cumulatively, as it was shown, Formaycin 10 L/ha can control the RKNs and can compete relatively compared to Fenamiphos (Nemacur) and other relevant bio-fertilizers in this research.
