Plants have defense mechanisms, which are activated against the attack of disease-causing agents. Within these mechanisms we have Polyamides (PA), which are polycationic compounds present in all living beings. In the cell membrane, polyamines bind to phospholipids and anionic sites, altering their permeability and fluidity, therefore, they indirectly modulate the activity of enzymes associated with the membrane (Galston and Kaur-Shawmey 1987) and exert a protective function. against stress (Evans and Malmberg 1989). Through exogenous applications of polyamines have been presented positive results on growth, development and protection against various biotic and abiotic stress in many plant species of agricultural and forestry interests as working with potato tubers (Solanum tuberosum L.) treated with Put, Spd and Spm where plants that emerged faster, more height and number of main stems, as well as increases in the production of tubers (Montenegro 1995). At present the problem of Stemphillium vesicarium “purple stain” is a major agricultural pest in the cultivation of asparagus, cost control constitutes 30% of the total cost of growing, reaching a total of 14 applications per season in winter when low temperature between 15 and 20 °C and relative humidity reaches a range between 95% and 100%. In this regard, the use of polyamines emerged as a possibility in finding alternatives for the control, set in the Integrated Pest Management (IPM) of Stemphillium vesicarium “purple stain” in the cultivation of Asparagus officinalis “asparagus” considering its use commercially to reduce the attack for the “purple stain”, which is a key condition for that crop. The results of this study showed that Alexigen (polyamines) increases the defenses of plants of Asparagus officinalis “asparagus” against attack by Stemphillium vesicarium “purple stain”.
