Abstract

The main efforts of scientists to reduce the appliance of nematicides that are commonly found in the markets led to an increase in the demand for safe, effective and environment-friendly alternatives. Hence, the present research aims to test three safe and effective substances, Humic acid (HA) concentration of 1500 ppm; Mychorrhizal fungi, Glomus mosseae and the commercial nematicides Bio-zeid (Trichoderma album) half dose compared with the nematicide Vydate on root-knot nematodes Meloidogyne javanica infected tomato plants, as well as its effects on the vegetative characteristics of tomato plants. The obtained results revealed that all tested materials decreased M. javanica J2 population density. The triple treatment (Humic acid + G. mosseae + Bio-zeid (half dose)) gave the best results, as it led to a decrease in the number of M. javanica J2 by 88.0%  more than that occurred by the chemical nematicide Vydate, which gave a reduction percentage of 87.1%. The triple treatment also led to a decrease in the numbers of root gall index by 80.0%. As well as triple treatment also improved the vegetative characteristics of tomato plants, it caused an increase in plant height, shoot weight and root weight by percentages (53.0, 29.0 and 148.1%) while contrariwise occurred by an appliance with Vydate (42.9, 21.4 and 92.6%), respectively, compared to the control. Thus, triple treatments can be recommended as a cheaper and safer alternative for plants and humans instead of chemical nematicides in integrated nematode control programs
