A disease characterised by loss of rigidity and
collapse of plant parts caused by loss of water and decreased
turgidity of cells. As drooping, folding, rolling, or collapsing
leaves that become weak and lose their freshness.
Wilts may be caused by:
- Water stress: loss of freshness or
drooping of plants due to inadequate water supply or excessive
transpiration or excess of fertilization.
- Vascular infection by a fungus or bacterium: A
frequent cause of wilt is a disease in which bacteria or
parasitic fungi invade the vessels of herbaceous plants,
interfere with movement of water and nutrients, and produce
certain toxins that cause wilting and the eventual death of
the plant. Many are carried by insects.
- Parasites attacking the roots.
