Abstract

Evaluation of chemical agents Salicylic Acid(SA) and Beta Amino Butyric Acid (BABA) agents to induce systemic resistance Results indicated that when BABA sprayed on foliage at rate 1000 and 2000 mg .L-1 and SA in 200 and 400 mg .L-1 highly reduced disease infection to 13.33 ، 10.00 ، 20.00 and 13.33% respectively with efficiency use 63.3 ، 72.5 ،50.0 ، 63.3% respectively compared to control(no treatment in presentence of pathogen without addition of inducing agents) with percentage of infection 36.33% . Biochemical analysis showed that treatment maize with 2000 mg.l-1 of BABA increased peroxidase activity the change in absorbance 44.10 min-1.gr-1 fresh weight after 5 days of treatment ،while treatment with SA at rate 400 mg.L-1 increased peroxidase activity the change in absorbance was reached 44.33 min-1.gr-1 fresh weight after 8 days. When BABA was use at 2000 mg .L-1 achieved phenols and prolin accumulation to rate 306.7 mg-1 .gr-1 fresh weight and10.33 µM-1. .gr-1 fresh weight after 10 days of treatment respectively.
