Evaluation of grafting effect on tomato crop yield and  Fusarium crown and root rot disease

Four compounds namely Fenor (F-760), Strom, salicylic acid (SA) and thiamin (B1) were tested against root rot disease of wheat under field condition. Wheat grains were soaked in these compounds for 6 h before sowing. Mean disease rating, disease appearance, and distribution of disease were estimated as parameters of disease severity. All tested compounds significantly reduced the root rot of wheat severity during seedling, flowering and ripening stages. Fresh and dry weights were also affected by application of these compounds. Water maintenance capacity in all stages was increased as a result of seed treatments by the above-mentioned compounds. Crop yield and parameters of spikes and grains were significantly improved. These results were discussed and analyzed statistically using LSD test.

Rot Disease

We studied the effect of water salinity on the incidence and severity of crown and root rot disease of tomato, as well as on the pathogen and on the plant's response to the pathogen. Irrigation with saline water significantly increased disease severity in tomato transplants inoculated with Fusarium oxysporum f. sp. radicis-lycopersici, and mineral fertilization further increased it. In one field experiment, disease incidence in plots irrigated with saline water (electrical conductivity [EC] = 3.2 ± 0.1 dS m-1) and in those irrigated with fresh water (EC = 0.4 ± 0.1 dS m-1) was 75 and 38%, respectively. Disease onset was earlier and yield was lower in plots irrigated with saline water. In a second field experiment, final disease incidence 250 days after planting, was 12% in plants which had been irrigated with saline water (EC = 4.6 ± 0.1 dS m-1) and 4% in those irrigated with fresh water (EC = 1.2 ± 0.1 dS m-1). Irrigation of tomato transplants with 20 mM NaCl did not inhibit plant development, but partial inhibition was observed at higher NaCl concentrations. Growth of the pathogen in culture or survival of conidia added to soil were not affected by saline water. Plants which were preirrigated with saline water were more severely diseased than those preirrigated with tap water. It was concluded that disease increases effected by saline water are associated with the latter's effect on plant response.
