| چکیده انگلیسی مقاله |
The use of different plant-based organic compound is an eco-friendly approach for management of plant-parasitic nematodes. In the present study, the aqueous seed extract of Wild Dill (Anthum graveolens), Wild Almond (Prunus lycioides), Ferulago (Ferulago angulate), Prangos (Prangos ferulaceae(, Marigold (Tagetes Erecta), Marigold (Tagetes patula), White goosefoot (Chenopodium album) and the aqueous leaf extract of Pomegranate )Punica granatumand( and Euphorbia )Euphorbia tirucalli( prepared using the Maceration method. The effects of all plant extracts at the rate of 0 (control), 0.1, 0.5, 1 and 2% on nematode egg hatching as well the effects of Wild Dill and Wild Almond extracts at the rate of 0 (control), 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3 and 0.4% on the mortality of the second-stage juveniles (J2s) of the root-knot nematode (Meloidogyne javanica) were evaluated, in vitro. For this purpose, suspensions, each containing 100±10 eggs or J2s were added separately to each Petri dishes containing 10 ml of mentioned concentrations of plant extracts and kept at 27±1°C under dark condition. After five days the results indicated that Wild Dill, Wild Almond, Pomegranate, Ferulago, Prangos, Marigold (yellow), Marigold (orange), White goosefoot and Euphorbia at the highest concentration rate (2%) reduced the hatching by 45, 35, 27, 21.8, 14.5, 26.8, 27, 24.4 and 10.2%, respectively, compared to the control. Likewise, after two days, the results indicated that the extracts of Wild Dill and Wild Almond at the rate of 0.1% increased the mortality of J2s by 75 and 86%, respectively, compared to the control. |
