Verticillium for Sale

Verticillium is a genus of fungi in the division Ascomycota, and are an anamorphic
form of the Plectosphaerellaceae family.
Solanaceous crop plants (tomato, potato, pepper, and egg- plant) may be infected at
any age by the fungi that cause Fusarium wilt and Verticillium wilt. The genus used to
include diverse groups comprising saprobes and parasites of higher plants, insects,
nematodes, mollusc eggs and other fungi thus it can be seen that the genus used to
have a wide ranging group of taxa characterised by simple but ill-defined characters.
Verticillium dahliae , a soil borne pathogen, belongs to the fungal class
Deuteromycetes (Fungi Imperfecti), a group of fungi, which do not have a known sexual
stage. The wilt organisms usually enter the plant through young roots and then grow
into and up the water conducting vessels of the roots and stem.  V. dahliae has a wide
host range. Over 300 woody and herbaceous plantspecies are known to be susceptible to
this fungal pathogen. The disease, Verticillium wilt, is problematic in temperate
areas of the world,especially in irrigated regions. There are no curative measures
once a plant is infected.
The better known species of Verticillium are, V. dahliae and V. albo-atrum cause a
wilt disease called Verticillium wilt in more than 400 eudicot plant species. As the
vessels are plugged and collapse, the water supply to the leaves is blocked.
Verticillium wilt is a soil-borne fungal disease that results in the yellowing, and
eventual browning and death of foliage, particularly in branches closest to the soil.
The wilt starts as yellow, V-shaped areas that narrow at the leaf margins. With a
limited water supply, leaves begin to wilt on sunny days and recover at night. These
yellow areas grow over time, turn brown, and then the leaf dies. Often, entire
branches are infected.
