Biography:

I am MohammadAmin Samh a professor in the field of entomology at Vali Asr University in Rafsanjan for 30 years. To pass the Research Sabbatical, I was at the University of Adelaide for a year. My field of work is ecology and pest management, and so far, I have published about 150 articles in this field

Abstract:

As one of the most important key pests of pistachio trees in Iran, the spread and outbreak of common pistachio psylla requires to be rechecked in terms of chemical control to reduce the amount of toxins and identify and apply environmentally friendly non-chemical methods. This study investigated the effect of applying natural mineral biochar of Kohbanan on activating the defense responses of pistachio trees and the feasibility of inducing resistance to control this pest by comparing the number of nymphs and eggs in the leaf. Changes in the activity of oxidative enzymes and non-enzymatic plant defense were examined. Foliar spraying of natural mineral biochar of Kohbanan caused a significant decrease in the population of common pistachio psylla nymphs on two sides of leaf. The amount of superoxide dismutase activity affected by this compound increased by 1.3 times compared to the control. The increase in catalase enzyme activity, total phenol content, and hydrogen peroxide amount affected by the natural mineral biochar was significant compared to the control treatment. According to the results, the application of natural mineral biochar of Kohbanan can increase the activity of oxidative enzymes and lead to the induction of resistance of pistachio trees to common pistachio psylla.
