- a disease symptom on woody stems or trunks. Resembles an
open break or wound and often persists from year to year.
- Conidium (pl. conidia)
- asexual spore of a fungus
- plant disease symptom where one or more individual stems
or branches start to die at the tip, with the disease spreading
down toward the base of the stem.
- "resting" period when growth slows almost to a halt; usually
occurs during the dry or cold season of the year.
- chemical used to control fungal diseases. Despite the
name, most fungicides only slow down or prevent the spread
of disease; only a few actually kill the fungus.
- Latent period
- the time period between when a plant becomes infected and
when it is capable of transmitting the disease to other plants or
to a vector
- along the long axis of an organism or object
- death of a plant tissue (leaf, stem, root) or of a part thereof
- Primary inoculum
- the source of a pathogen when it first appears during the growing season
- Pycnidium (pl. pycnidia)
- a tiny, dark, round fruiting body of a fungus. Produces
- Seta (pl. setae)
- hairs or whiskers in the spore-bearing structures of certain fungi
- Stratified sample
- a sample taken by first dividing the population (e.g. a field)
into subsections, then taking samples within each subsection
- plant growth that is green and soft, not woody
- of or pertaining to the conductive tissues of a plant stem.
These tiny tubes move water up from the roots, and sugars and
other materials down from the leaves.
- a plant or animal, often an insect, that carries disease organisms
