Abstract

This study was carried out to investigate the effect of five chemical inducers i.e. salicylic acid, ascorbic acid, catechol, citric acid and potassium silicate and six fungicides i.e. Actamyl70%, Chlorothalonil 50%, Evito 48%, Shenzy 34%, Pyrus 40% and Fentobein 32.5% in order to control Rhizoctonia solani and Macrophomina phaseolina which infect sugar beet roots. The antioxidants, catechol and salicylic acid achieved the best disease control at all rates of application followed by citric acid and potassium silicate, respectively. Concerning fungicides, Shenzy 34% gave noticeable control in disease reduction followed by Evito 48% and Fentobein 32.5%, respectively. Usage of antioxidants as chemical inducers for enhancing plant resistance and capability of defying diseases is well recommended as fungicide alternatives due to their safe influence on human health. But, fungicides are still the most widespread used compounds in disease management strategies, based on their compliant application, reliable and efficient results than any other safer chemical or natural compound which controls the disease by reducing the losses, not by eradicating the disease in which fungicides can do successfully.
