Biennial Weed | Biennials require two growing seasons to complete their life cycles. They usually produce vegetative growth the first year, then flower and set seed during the second year |
Instars | A phase between two periods of molting in the development of an insect larva or other invertebrate animal. |
Noxious Weed | A plant considered harmful to animals or the environment. |
Vector | An organism, typically a biting insect or tick, that transmits a disease or parasite from one animal or plant to another. |
Nematodes | Any of a phylum (Nematoda or Nemata) of elongated cylindrical worms parasitic in animals or plants or free-living in soil or water |
Insect | Any small invertebrate animal, especially one with several pairs of legs. |
Chemical Control | Chemical pest controllers are pesticides used to destroy and eliminate annoying pests that contain chemicals unsafe for human consumption. |
Metamorphosis | A change of the form or nature of a thing or person into a completely different one, by natural or supernatural means. |
Casual Agent | The biological pathogen that causes a disease, such as a virus, parasite, fungus, or bacterium. |
Perennial Weed | Perennial weeds live for three or more years. Perennials produce new vegetative growth from growing points at or below the soil surface. |
Hyphae | Each of the branching filaments that make up the mycelium of a fungus. |
Diseases | A disorder of structure or function in a human, animal, or plant, especially one that produces specific signs or symptoms or that affects a specific location and is not simply a direct result of physical injury. |
Disease Triangle | One of the first concepts encountered by college students in an introductory plant pathology course |
Bacteria | Microorganisms made up of a single cell that has no distinct nucleus. |
Annual Weed | Annuals are plants that complete their life cycle in one growing season. |
Biological Control | The control of a pest by the introduction of a natural enemy or predator. |
Pesticide Resistance | The ability of a life form to develop a tolerance to a pesticide. |
Cultural Control | The practice of modifying the growing environment to reduce the prevalence of unwanted pests. |
Arachnid | A kind of animal that has eight legs and a body formed of two parts. |
Viruses | An agent that is infectious that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host. |
Eradication | The complete destruction of something. |
Key Pest | An insect, mite, disease, nematode or weed that frequently results in unacceptable damage and thus typically requires a control action. |
Quarantine | A state, period, or place of isolation in which people or animals that have arrived from elsewhere or been exposed to infectious or contagious disease are placed. |
Fungi | Any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools. |
Pathogens | A bacterium, virus, or other microorganism that can cause disease. |
Compound | A chemical substance that is composed of more than one element. |
Signal Words | The required word on the label that denotes the relative toxicity of the product. |
Net Contents | The amount of pesticide in the container. |
Carcinogen | A material capable of producing a cancerous tumor. |
Toxicity | A measure of how poisonous a chemical is. |
Xylem Tissue | Where water and minerals are transported within the plant. |
Insecticides | Chemicals used to control insects. |
Phloem Tissue | Responsible for the transporting of carbohydrates within the plant. |
Common Name | Given to a pesticide by a recognized authority or pesticide nomenclature. |
Symbols | A warning illustration located on a chemical container that warns of chemical toxicity to humans and animals. |
Volatilization | Changing to gases. |
Drift | The movement of a pesticide through the air to non-target sites. |
Trade Name | The manufacturer's name for its product. |
Element | A uniform substance that cannot be further decomposed by ordinary chemical means. |
Formulation | The physical properties of a pesticide |
