Systemic action
The ability of a pesticide or fertilizer to be absorbed by a plant and translocated through its vascular system to other parts of the plant.
Также говорят: systemic effect, systemic translocation, systemic pesticide
Systemic action refers to products that move through the plant's xylem or phloem, protecting parts of the crop that were not directly reached during application. This ensures that new growth remains protected and the treatment is not washed away by rain or irrigation.
These products are best applied during periods of active metabolic growth when the plant is effectively circulating nutrients and fluids. This method is essential for controlling internal pests or pathogens that thrive within plant tissues.
A common mistake is applying systemic agents under weather stress, which halts plant circulation and prevents the product from reaching its target. Users should also strictly follow pre-harvest intervals to ensure the compound has broken down sufficiently before consumption.
