Fungicide

Definition - What does Fungicide mean?

A fungicide is a substance, often a chemical, that is used to kill fungi, fungal spores, and fungal infections. There are both natural fungicides and synthetic fungicides available. In general, commercial fungicides, which are usually synthetic, are commonly used in horticulture in order to kill fungal pathogens that have infected plants.

MaximumYield explains Fungicide

Fungal pathogens are the No. 1 cause of crop loss around the world and can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit in both plants and animals.

In organic gardening, fungi are often treated by washing plants with a light, soapy solution, but this gentle approach is not practical for commercial agriculture. For this reason, commercial growers almost always choose to use a fungicide. Fungicides can either be contact, translaminar, or systemic in nature.

Contact fungicides are substances that are applied directly to infected leaves or stems. They only protect the area where the spray is deposited.

Translaminar fungicides are redistributed from the upper, sprayed leaf surfaces to the lower, unsprayed surfaces.

Systemic fungicides, which are drawn up through the roots and redistributed through the xylem vessels, move to all parts of a plant.
