Abstract
In this study, the potential of some bio-agents, fluopyram and fosthiazate were investigated against root-knot nematodes (Meloidogyne spp.) on guava trees under field conditions for two successive seasons (2020 & 2021). The examined bio-agents were; Bio-Nematon® (Paecilomyces lilacinus), Bio Cure-F® (Trichoderma viridi), Bio Cure-B® (Pseudomonas fluorescens) and BIOTECT® (Bacillus thuringiensis var. kurstaki). The infection parameters of root-knot nematodes (Meloidogyne spp.) were recorded at 35 and 70 days after treatment. Results indicated that all the applied treatments suppressed the soil population density (J2/250g soil) at range of 68.75 to 88.85% during the 1st season, and from 57.72 to 92.92% during the 2nd season. Besides, the numbers of root galls were decreased at range of 60.22 to 77.11% and from 57.90 to 70.90% during 1st and 2nd seasons, respectively. Also, the number of isolated eggs from roots was decreased at range of 67.13 to 94.61% and from 51.37 to 88.45% during 1st and 2nd seasons, respectively. However, the content of total N, P and K (%) in leaves of guava trees was fluctuated during both seasons.
