Bacterial diseases of plants
are a concern for farmers. This is because the reduction in crop yields affect
the entire economy based on agriculture. There are many different types of
diseases that are caused by bacteria in plants. Plagues, leaf spot and other
diseases that affect plant growth.
Bacteria on plants in many
different ways. Manifestation of these infections can be observed in the form
of diseases of all kinds.
Crabs
Crabs are deposits of dead
plant tissues and, resulting from bacteria, fungi and other microbes. The term
technical or scientific is used interchangeably with cancer is anthracnose.
Different bacteria are responsible for the development of cancer in different
plants. Crabs are in citrus plants observed by the bacterium Xanthomonas
axonopodis causes. The bacterium called Xanthomonas populi is responsible for
cancer development in aspen, a deciduous plant. Crabs in most cases can not be
processed and affected plants must be destroyed. However, bactericides are used
when the problem is not great.
Bacterial wilt
Vascular tissues of plants are
attacked by bacteria in the wilt disease. The plants of the Cucurbitaceae
family are affected by bacterial wilt. Erwinia tracheiphila is the causative
agent of this disease. This bacterium grows in the tissues of plants and xylum
affects the transport system of the water. The mechanical locking system, the
water transported in plants, which leads to wilting. Wilting of leaves is one
of the first symptoms of this disease. Later, the disease spreads to other
parts of the plant, and eventually the whole plant wilts and dies. It is not
possible to treat plants affected by bacterial wilt. With varieties of pumpkin
plants less susceptible to bacterial wilt is the only way to alleviate the
problem.
Bacterial
This disease is characterized
by chlorosis of various plant tissues. Flowers, leaves, twigs and affected
plants produce less chlorophyll, and browning. The bacterial disease can also
lead to plant death. Fire blight is a disease in pear and apple plants found;
Erwinia amylovora is the bacterium that causes fire blight. In this disease,
the affected areas of submerged plants and appear to be burned, the surface of
these plants turn, cracks are observed on the surface. To get bacterial from
spreading further, the chemicals can be used as terramycin.
Brown spot disease
The agent of this disease is
the bacterium called Pseudomonas synringae. The signs of this disease have been
observed are: gray spots, tears of leaves, leaf margins brown-yellow, etc., hot
and humid climate is favorable for disease development. A white substance
oozing from the infected plants and spread on the fruit surface. Reduction in
crop yield is observed in the brown sports. This disease affects mainly vegetables
and ornamentals. The use of resistant varieties should help overcome the
problem of brown spot disease.
Crown gall
The disease is soil-borne and
involves a variety of plants such as roses, apples, cherries, raspberries, etc.
The disease is due to gall (abnormal growths) in rings formed (ie instead of
cutting the stem and roots) named these plants. Agrobacterium tumefaciens is
the causative agent of this disease. Disease of the gallbladder treated or
controlled by the use of chemical and biological methods both. A chemical
called GALLEX can be painted on bile for treatment purposes. The biological
method of control is that inoculation of seedlings and new transplants with
bacteria for growth in competition with pathogens. This method automatically reduces
the number of pathogenic bacteria.
The spread of pathogenic
bacteria
There are many different types
or modes of spread of pathogenic bacteria. The use of seeds of infected plants
or plant obtained contributes to the spread of disease from one place to
another. Tools and equipment used for various agricultural operations carry the
bacteria that cause diseases from one field to another. Rain also plays an
important role in the spread of pathogenic bacteria. Buzzle Article on plant
diseases caused by fungi, should also prove useful to readers.
The various bacterial diseases
are treated by means of an integrated management approach. It is difficult to
fully cure, or vice versa, the spread of bacterial diseases mentioned above. To
do the right thing is to prevent the spread of the disease, you can think about
prevention of bacterial diseases by the use of resistant plant varieties.
Accordance with the quarantine rules or guidelines is also a means of
preventing the spread of bacterial diseases. The use of chemical pesticides are
the measures most commonly used for treating bacterial diseases. Antibiotics
such as streptomycin and oxytetracycline are useful in controlling the growth
of pathogenic bacteria. Bordeaux mixture is an old chemical pesticides in the
treatment of bacterial diseases of plants used.
