Abstract
A pot trial was conducted to estimate the role of Trichoderma harzianum alone or in combination with two organic substances, potassium humate and chitosan in controlling Meloidogyne incognita on tomato. All treatments caused greater decreases in parameters of M. incognita in comparison to the control treatment (nematode only) and this led to noticeable enhancements in growth and yield of tomato. The lowest numbers of eggmasses, eggs/eggmass, galls/root, females/root, and second stage juveniles/250 g soil were recorded due to the combination of T. harzianum (1010 spore/ml) with chitosan and potassium humate after 120 days from the transplanting of tomato seedlings. Also, this treatment showed the best promotion for all tomato parameters (lengths and weights of shoots and roots, and productivity). So, mixing chitosan, potassium and T. harzianum is highly recommended to be used as an effective bio-nematicide against M. incognita on tomato plants.
