Pesticides in soils and vegetables can
be averted by pretreatment with microorganisms degrading
pesticides found in verticillium sp to alleviate the
condition in plants. Verticillium sp is an active biological
metabolite. This can be used for removal or detoxification
of chlorpyrifos residues in contaminated soil and vegetable.
They grow fast and are pale yellow in color, becoming
pinkish brown, red green, or yellow with colorless,
yellow or reddish brown reverse. The genus is always
isolated from the environment. Verticillium sp have
a rare cause of corneal infections.
Verticillium sp produce culturing microorganisms
that can be used to manufacture or produce aphidicolin.
Plant pathogenic verticillium species are important
in over 300 crops in the sub tropical and temperate
regions. There are great amounts of cellulose wastes
produced from agricultural activities and industrial
food processing. The presence of microorganisms that
can remove, reduce or alleviate that the polluting materials
is an environmental challenge.
Verticillium sp is a fungus that belongs
to the kingdom of organisms that include dry and powdery
growth called molds and yeasts. The health effects resulting
from fungal exposure may be dependent on dosage and
cause of exposure and vary on individuals.. The growth
of the pathogenic fungi can cause opportunistic diseases.
They thrive more under humid, nutrient available areas
and with favorable temperatures. They have strong anti
fungal activity.
They affect plants roots and are difficult
to eradicate. The fungus grows into the xylem of the
plant. The conidia are transported to the plant by the
fluid in the xylem. This may result into wilting of
the plant. After the plant dies the infected tissues
decay and microsclerotia are released and these can
survive several years in the soil. Therefore the disease
can recur for many years while affecting plants. The
major symptoms of this disease is leaves on one side
of the tree wilt, smaller yellowish leaves, leaves dry
and fall off the branches. Infected trees may die or
survive for years. A cross section of the stem will
show discoloration in rings.
When this happens to plants it is advisable
to prune the affected leaves, disinfect tools before
working on another plant, and reduce nitrogenous fertilizer.
Avoid planting the same plant type on the same soil
and conduct verticillium soil test before planting.
There are chemical control measures such as pre plant
fumigation and injection as preventive measures.
