Protective role of antifusarial eco-friendly agents ( and salicylic acid) to improve resistance performance of tomato plants.

wilt triggered great losing in tomato plants quality and quantity in all worlds. In the recent experiment, physiological resistance performance in tomato seedlings using and salicylic acid (SA) either (individual or combination) anti had been studied. antifungal prospective of and SA against F. oxysporum were also examined. A noticeable antifungal capacity with highest activity of 10 and 8 mm ZOI after the treatment with the and SA Also, have great ability to decreasing growth by 25% inhibition at dual culture method. The MIC of SA was 1.5 mM to reduce growth. For more ultrastructure by TEM of treated with SA and showed alteration of cell wall as well as cytoplasmic components of mycelium, macroconidia and microconida. In the current experiment, ameliorative potentials of and SA either (individual or combination) via soil or foliar application were administered to the - infected tomato plants and then disease index, growth indicators, photosynthetic pigments, metabolic markers, and antioxidant isozymes were assessed. The achieved result indicates that and SA through two modes (foliar and soil) lowered PDI by 12.50 and 20.83% and produced great protecting ability by 86.36 and 72.2%. The results revealed, infected seedlings exhibited high decrement in all tested growth characters, photosynthetic pigment contents, contents of total carbohydrate and protein, whereas proline, phenols and enzymes' activity were elevated under infectivity. It was concluded that use of combination ( and SA) acted as a commercially eco-friendly instrument for intensifying the defense system of tomato plants against wilt.
