Evaluation the efficiency of Soil Solarization, Trichoderma harzianum, Trichoderma viride, Paecilomyces lilacinus, Glomus mosseae and nematicide furfural against root-knot nematode Meliodogyne javanica on tomato plants

Abstract

This study has been conducted to evaluate the interactive effect of soil solarization, Trichodema harzianum, Trichoderma viride, Paecilomyces lilacinus, Glomus mosseae and Furural on root- knot nematode Meloidogyne javanica on tomato. The results revealed that there were significant effects of solarization alone or in combination with the other control agents on all tested growth parameters of tomato plants. The length of stem and root were 10.6, 12, 5.2, 5.7cm with solarization and non-solarization soils respectively. There were synergistic interaction between solarizaton and control agents, the length of stem and root in Furfural, T. harzianum, T. viride, P. lilacinus, G. mosseae treatmens were (25.3 , 38.2),(18.8 , 29.2),( 15.8 ,17.3), ( 15.2 , 23.1), (13.8,18.8) cm with solarization and (14.7 , 15.2) , (15.4, 21.5 ) , (12.1, 12.1 ) , (9.8,15.1) , (11.2,11.3) cm with non- solarization respectively. The solarization was found to be efficient in reducing the number of root knots per one gram of root of tomato with synergistic interaction with all control agents especially Furural. Generally, Furural has significant superiority in its effect on all growth parameter, followed by T.harzianum, and it was the most effective in reducing number of root-knot (5.6,29) knots for solarized and unsolarized soil respectively followed by T. harzianum , P. lilacinus, .G. mosseae( 42,45,49 )knots /gm roots with solarization.
