| Abstract | ||
| The nematicidal efficiency of four formulations of emamectin benzoate against the root-knot nematode Meloidogyne incongnita was evaluated in this study under laboratory (in vitro) and greenhouse conditions (in vivo). The four formulations—emamectin benzoate EC (Pasha 1.9%), WDG (Al-trabok 5.7%), SG (Armicid 5%), and WG (Emamect 5.7%)—were compared at different exposure duration's. Results showed that all treatments significantly caused juvenile mortality, decreased infectivity, reduced nematode reproduction in tomato, and lowered gall formation. LC₅₀ and LT₅₀ values were (25.84 ±0.26 μg/ml and 29.41 hours) indicated that WG (Emamect 5.7%) was the most effective and fastest-acting treatment, followed by SG (Armicid 5%) (45.86 ± 0.26 µg/ml and 29.43 hours) and EC (Pasha 1.9%) (35.43 ± 0.24 µg/mL and 69.23 hours), with no significant differences among them. WDG (Altrabok 5.7%) was the least effective (121.0 ± 0.37 µg/ml and 77.36 hours). Under greenhouse conditions, WG (Emamect 5.7%) and SG (Armicid 5%) showed significant reductions in nematode reproduction and gall formation and improved plant growth parameters (shoot length, weight, and leaf number) compared to untreated controls. The results suggest that WG and SG formulations are effective options for managing root-knot nematodes in tomato cultivation. | ||
