A systemic inducer comprising a chemical compound combined with microorganismic substance extracted from non-plant pathogenic microorganisms. The compound includes an acid and/or the salt of phosphorus, potassium, calcium, sodium, magnesium, manganese, zinc, copper and iron. The microorganismic substance may be extracted from fungus, bacteria or virus. The systemic inducer may be applied to stems, leaves, seeds, flowers or fruits of plants. Alternatively, the systemic inducer may be applied to soil to elicit a response via the roots of the plants. Finally, the systemic inducer may be injected into the stem or pseudo stem of the plants. The inducer effectively enables the induced plants to resist attack by pathogens to plants, seedlings, leaves, fruits, flowers and roots.
