Efficacy of Camphor and Casuarina Leaf Powder or Water Extracts on Meloidogyne Incognita Infecting Tomato Plant under Green House Condition

A pot experiment was carried out to evaluate the impact of camphor and Casuarina dry leave powders or water extracts as single or mixed application with nematicide on tomato plant infected with of M. incognita under greenhouse conditions. The Triple application of ⅓ Casuarina and ⅓ camphor water extract (5 ml each) + ⅓ oxamyl (0.1 g) was significantly (P ≤ 0.05) exceed other materials in the increment of total plant growth parameters and recorded high values of nematode reduction criteria that were amounted to 91.5, 92.53 and 94.81%, respectively, comparing to nematode alone. The application of dual ½ Camphor water extract and ½ oxamyl at halve doses each beset other binary treatments in the increase percentage values of such plant growth features and nematode parameters too. The nematode pesticide, oxamyl recorded a significant (P ≤ 0.05) increment in plant length (51.86%), shoot fresh weight (36.79%) and shoot dry weight (64.31 %) respectively and recorded a lowest reproduction factor (RF) with value 0.16 as compared with compared to those received nematode alone (2.43).
