Term used to describe pesticides or fungicides that are taken up by plant leaves and growths and then work from within the plant.

A pesticide which goes inside the plant and travels in the sap stream. [ GO BACK TO TOP INDEX

Taken up through the roots or leaf tissues into the cells of the cotton plant (as opposed to remaining on the surface), often in concentrations high enough to affect a biological change (e.g., at planting soil insecticides taken up by cotton seeding roots and transported through the plant's vascular system to suppress or kill leaf-feeding thrips or Roundup herbicide absorbed into the vascular system of weeds and translocated to the root zone in high enough concentrations to kill the weed).

systemic pesticide is capable of being translocated to sites other than where it was absorbed in sufficient quantities to be biologically effective.[] [] [] [] [] [] [] [] [ I-J-K] [] [ M-N] [ O-P] [ Q-R] [] [] [ U-V] [ W-X-Y-Z

A compound that moves freely within a plant so that application to one area will result in movement to all areas of the plant to exert its effect.

insecticides or fungicides that enter through plant leaves, poisoning the leaf and sap.

pertaining to a disease in which the pathogen (or a single infection) spreads generally throughout a plant; pertaining to chemicals that spread internally through a plant.

Refers to a pesticide that is absorbed into plant stems and leaves and makes the entire plant toxic to insects.

a chemical taken up by the root system, distributed throughout the plant and to the foliage

a chemical that is absorbed by the roots and transported through the plant to poison feeding mites

Typically refers to fungicides and pesticides that work by moving through the plants vascular system, rather than by direct contact.

(as it applies to plants) Absorbed through the root and into the plant juice or sap without harming the plant itself.

Pertaining to a disease in which an infection leads to general spread throughout the plant body. Also, a chemical that spreads internally through a plant. Teliospore - Thick-walled resting spore produced by some fungi, notably rusts and smuts, that germinates to form a basidium.

a parasite which spreads throughout the host; a fungicide that is absorbed by the roots and is translocated to other parts of the plant.

Pertaining to a system.

The description of an insecticide or fungicide that acts by entering the sap of the plant and counter-acting infestation or disease from within over a period of time.

A chemical which is absorbed directly into a plants system to either kill feeding insects on the plant, or to kill the plant itself.

( systemically): Spreading internally through the plant body; said of a pathogen or a chemical.

Used in reference to a disease within the plant tissue, not initiated from the external cells. Also refers to materials and compounds which are taken up or absorbed by the plant and designed to fight disease (e.g. systemic fungicide).

able to move or circulate within a plant. Some diseases and pesticides are systemic.

Siss-TEM-ihk) In reference to a chemical pesticide, a systemic chemical is applied to the growing medium, often in a granular or micro-encapsulated form. Its active ingredient(s) is translocated through the plant via the plant's vascular system.| Menu

Of a chemical or a pathogen: Spreading internally throughout the plant body. ()
