What is Virus?
Plants capable of making sick
and cannot even be seen with a light microscope
small structure, a live
is an organism that needs structure.
Bacteria and fungi
giving poisonous substances
however, such an event is not the case with viruses. Diseases caused by viruses
not only poisoning the plant
cell proliferation of plants
inside the cell
completely fills the cell’s vital activities
negative effects. Absolutely any plant
they do not give toxic substances.
Transport of Plant Viruses
Plant viruses in many ways from plants to plants
moved. Conveying ways of vaccine and steel, plant sap,
mechanically by means of seed, pollen, scum, and
insects, mites, nematodes and fungi.
1-Vaccine Transport: From a plant infected with virus
vaccination of the vaccine in a healthy sapling
as a result of relocation.
2-Moving with plant sap: One plant with another
direct sap by means of contact of the plant
mechanical transport of plant viruses by transfer.
It is one of the most important ways of moving. Just
plants during contact with each other, plants
cause of inattention in applications
with the virus can be carried. For example;
after pruning at an infected plant
a non-infected plant, pruning tools
Pruning virus without disinfecting is clean
moves to the plant. Used in such operations
tools and equipment
needs to be disinfected.
3-Seed Transport: More than a hundred viruses
portable with small seeds. Seeds germs
side of the wounded viruses into the seed
it is also easier to enter.
4-Pollen Transport: Plant pollen found in
viruses move into the flowers of healthy plants
disease of plants.
5-Moving with Insects: Surely the most
viruses that cause economic damage
Moves insects.
Insects that carry several viruses at the same time
has. Aphids, white flies, leaf fleas and
thrips are the most important virus carrier insects. Insects with insect-absorbing mouth structure
during feeding
viruses with the plant to feed
is a form of transport.
6-Transport with Nematodes: Insects like this.
7-Moving with Fungi
8-Weed Moving: Especially full parasite
structure of dodder plant virus transport
It is important.
Commonly seen in vegetables and fruits
viruses
Vegetable Viruses
1- Beans Common Mosaic Necrosis Virus
Characteristic symptoms bright green-yellow on leaves
and dark green mosaic stains. Usually vessels
dark green color while the intravenous areas are bright
becomes greenish yellow. Color change in leaf
usually wrinkles, puffiness, deformity
and signs of curling the leaves downwards
seen together.
2- Bean Yellow Mosaic Virus
Young leaves are yellow and green mosaic.
Some breeds of the virus cause leaf fall.
Flower loss, flowering delay, plant
Other common symptoms of shortening of the neck.
The number of seeds in the pods is low and late
It matures.
3- Cucumber Mosaic Virus
Among the hosts are many vegetables, ornamental plants
and other plants. Cucumber, zucchini, vegetables
pepper, tomato, melon, watermelon, spinach, onion, eggplant, potato, tobacco, carrot, parsley, radish, okra,
broad beans, lettuce, cabbage, leek, sugar beet
plants.
4- Tomato Yellow Leaf Frizz Virus
Also among the people as a male disease
known. The first symptom of the disease
yellowing between the veins. Sick of plants
leaflets curl inward and outward. Leaf blade
becomes extremely small. Damage to ripening fruits
new fruit formation is prevented.
Plants caught before flowering disease
It is stunted. Significant product loss occurs. Virus,
some plants, including tobacco.
White flies are carriers of the disease.
5- Spotted wilt virus
Growth of young plants at the ends, end of the leaves
looks like downward curl and fading
emerges. Stem and leaf of tomato plants
brown streaks may occur on the stem. Diseased
plants stunted. Plant disease before flowering
fruit is not caught. After flowering
nested rings in the fruits of infected plants
spots are seen. Virus, over 160 plants
disease. Disease through Thrips
with.
6- Tobacco Mosaic Virus
Tomatoes, peppers, eggplant, beans and many
plant disease. Usually light and dark
green areas with green areas mixed together
speckles. The newly emerging leaves curl and
structure is degraded. Much more severely affected
Leaves shape completely degraded and appearance
resembles fern leaves. Plants a
to stunted and plants during the seedling period
can spread very little fruit. Fruits
contamination after reaching maturity
very small shrinkage of plants and fruits
It may come. Necrotic spots or lines on the body and
can be seen in fruits. Sometimes fruits are irregular
matures or fruit walls
turns brown.
Fruit Viruses
1- Sharka Virus
Plum, the most important hosts of the disease,
Symptoms in apricot and peach leaf and
fruit is seen. Leaves of plums and apricots
indicated, yellow stain, band, ring-shaped.
Leaf symptoms in peaches color along the veins
opening, yellow spots and deformation of the leaf
in the form. Symptoms spring, first
foliation cycle. Apricots and
Symptoms of an entire vegetation leaf in plums
visible, especially the shade and cool interior of the tree
in parts, young shoots are evident
Fruit signs; plum
dots and bands or rings
Deposits occur near the death circuit.
In the fruit section, the dark
brown, rubbery and adhering to the core
It is seen. Sign of fruit in the seed
drop occurs. These are dark dots,
rings and bands. Apricot in general
fruit deformation, rings and bands are seen.
Symptoms in the kernel are very pronounced.
Peach fruit apricot-like symptom
Shows.
Fruit breakdown of all three types of fruit
seen before, it is quite important.
2- Ligament Short Knuckle Virus
Short knuckle virus in vineyard leaves
characteristic deformations.
Leaf veins abnormally dispersed to the leaf
gives a fan look. Ring on young leaves
or streaks and oil spots
It is seen. After these symptoms disappear,
The place receives systemic green or yellow mosaic stains.
Shortening between nodes, formation of side shoots
Since it is thin and frequent, it gives the appearance of shrub to hang.
Since it is carried with a wedged nematode, the new
nematode
regions.
Combating Viruses
- Elimination of Infection Sources
- Vector (Carrier) Insect Control
- Use of Durable Varieties
- Using Ari Seedling or Sapling from Virus
- Fighting Weeds
- Destruction of infected plants
