Abstract: (48 Views)
Humic acid (HA) is the most important and widely used biostimulants in agriculture. As a powerful, multifaceted tool in increasing soil health and plant resistance, HA has significant effects for sustainable agriculture and plant disease management. This safe organic compound controls diseases through direct and indirect mechanisms. In the indirect dimension, HA creates an unfavorable environment for the development of pathogens by improving the physical structure of the soil by increasing porosity and ventilation, enhancing the cation exchange capacity and chemical fertility of the soil, as well as stimulating the population of beneficial soil microorganisms. In addition, HA strengthens the plant by stimulating the development of the root system, facilitating the absorption of water and nutrients, and especially by activating the mechanisms of inducing systemic resistance in the plant, leading to the production and accumulation of defensive metabolites increasing the activity of defensive enzymes, and the proteins associated with pathogenesis. This article provides a summary of the effectiveness of HA as a plant stimulant on plant pathogens and the prospects for its use to reduce the use of chemical pesticides or even replace them in controlling plant diseases. A good understanding of the function of biostimulants, including humic acid, will help farmers and agricultural scientists in their better use.
