Other claims from this paper (11)
- Intervention effect A. annua essential oil at 250 ppm gave the highest in vitro nematistatic activity, 100% paralysis of nematodes after 48 h.
- Intervention effect M. azederach methanol extract at 500 ppm gave the highest in vitro nematistatic activity, 100% paralysis of nematodes after 48 h.
- Intervention effect A. annua essential oil had the highest nematicidal activity, about 60-100%.
- Intervention effect A. annua aqueous extract had nematicidal activity of about 40-87%.
- Intervention effect M. azederach methanolic extract had nematicidal activity of about 38-100%.
- Observation All concentrations of M. azederach methanolic extract and high concentrations of A. annua essential oil and aqueous extract acted as repellents and motility inhibitors for nematodes.
- Intervention effect In the greenhouse all treatments significantly reduced the citrus nematode population in soil and roots compared with the control.
- Intervention effect The maximum reduction of the citrus nematode was observed with 500 ppm methanolic extract of Melia azederach.
- Intervention effect Plant height increased compared with the control when the treatments were applied.
- Intervention effect Fresh and dry shoot and root weight increased compared with the control when the treatments were applied.
- Recommendation The authors consider A. annua and M. azedarach promising control agents for citrus nematodes.
