الملخص EN

The results of the effect of three commercial products (fertilizer equations 30: 10:10 and 20:20:20 and 10:20:30 nitrogen: phosphorus: potassium, respectively) of the foliar compound fertilizer (NPK) Pro.sol in plastic house in the number of tunnels caused by the tomato leafminer, Tuta absoluta, on tomato leaves of the seedlings of Wijdan variety that there was a decrease in the number of infestation signs (tunnels) started from the forth reading dated 25\4\2013 significantly in comparison with all other fertilizer formulations and control treatment.

In terms of the number of larvae / plant observed a significant decrease in plants fertilized with three preparations, reached to 0.04 and 0.05 and 0.053 larvae / plant, respectively, compared to the control treatment (0.113 larvae / plant).

Results of the organic fertilization with cow manure in field of tomato crop showed significant decrease in the number of tunnels/ plants in fertilization treatment, which ranged between 3.40 and 4.25 Tunnels / plant at 02/06/2013 for each of slit down the plant and scattering inside rows fertilization respectively, compared to the control treatment (7.69 tunnels / plant).

It can be concluded that all fertilizer formulation used in this research led to a reduction in the number of tunnels in the leaves of tomato plants and reduce the number of the larvae, We recommend to use a foliar fertilizer compound Pro.sol to reduce the sensitivity of the tomato plant to infestation with tomato leaves leafminer.
