In a similar manner, salicylic acid is a factor in disease resistance. Anapplication of salicylic acid induces a typical disease-resistance responsecalled systemic acquired resistance, or SAR. Other materials, such asjasmonic acid, peptides, amino-acid analogs, fatty-acid derivatives,phenolic compounds and silicates also induce systemic resistance topathogen attack.

Because humic acid and seaweed extract exhibit cytokinin-like auxin-likeactivity, these and other biostimulants that contain hormonal materials maysignal plants to switch on their defense system to harsh environments.
