Organ

the part of the plant that most conspicuously is hit by the parasite

bud: both flower buds and leaf buds
flower: also inflorescence
leaf: also needle, phyllodium, petiole
leaf bud: also unfolding young leaf
root: also root stock, runners
root collar: also the lowest part of the stem
stem: also culm, the lower part of the peduncle, in grasses also leaf sheath
systemic: the entire above-ground plant

PARASITIC MODE

borer: larva living internally, almost no outwards signs
canker: restricted area of dead plant tissue
down: 0.5-2 mm high fungal down
film: very thin cover of fungal tissue
free: free-living, vagrant
gall: swelling and/or malformation
hidden: concealed by dense webbing, leaf folds etc.
leaf spot: discoloured, often ± necrotic, generally not galled, sign of a fungus infection
miner > borer: larve initially makes a mine, lives as a borer later
pustule: plug of fungal tissue, generally brown-black and < 2 mm
saprotrophic: developing on recently dead, still identifiable, plant tissue
scale: scale insect
stripe: longitudinal line of fungal tissue in a grass leaf

FILTER AND SORT TABLE

To filter the table above, add a text to the search field (top right of the table).
To sort a column click on an arrow after the column name (both ascending and descending).
Sort multiple columns with Shift + click on the arrows.

IMPORTANT

The host plant spectre of a parasite is rarely known exhaustively; this applies in particular at the species level. It is advisable therefore to check at least also the list of all parasites of this genus.
