How to Handle This Destructive Tree Disease

Fire blight is a devastating bacterial disease that primarily infects apples, pears and related tree members. If you grow a tree on your property, then you need to understand this bacterial disease because it kills flowers, sprouts and organs. It is not uncommon for a fire defect to kill entire trees!

Unfortunately, the fire defect is difficult to control, so we will include the necessary preventive measures you need to know. Let us know what is Agni Dosha and what are the symptoms on your tree.

What is a fire blight?

Without a doubt, Agni Dosha is one of the most dreadful bacterial diseases that infect fruit trees and shrubs. Preventive measures help reduce the risk of disease on your entire tree, but it is almost impossible to eliminate. If this disease is in your area, use caution.

Agni Dosha is a bacterial disease that affects plantations as well as trees and shrubs, so most plants are not protected from this disease. It is named because of the scorched appearance on infected leaves.

It is caused by bacteria Erwinia Amilovora, And it is most common on pomegranate trees. Pear and quinn trees are susceptible, along with apple, crabapple and firethorn trees. Less commonly, Agni Dosha infects hawthorn, loquat, mountain ash and other related plants.

The disease is affected by seasonal weather and prefers to attack plant flowers, gradually moving towards the twigs and branches of the plant. This makes the flowers and twigs appear burnt, which makes it easy to identify the disease.

Life cycle of Agni Dosh

The bacteria overwinter in cankers on the twigs, branches or trunks of host trees. Then, in the spring, when the weather begins to get hot and moist, a small number of cankers become active again. Bacteria begin to spread and grow.

This bacterium spreads through the air, hail or insects, so if it finds a tree or shrub in which young leaves or seedlings are bruised, it can easily invade. It spreads rapidly when the weather is warm yet rainy or humid.

The strength of the tree affects the extent of damage. Healthy trees are at low risk. Once the disease has established itself in your trees, the pathogen passes through the vulnerable parts of the tree and finds other vulnerable hosts nearby. Young trees are more likely to become infected and cause serious damage.

What are the symptoms of Agni Dosh?

Symptoms of Agni Dosha begin as soon as the trees and shrubs start growing actively in the spring. These bacteria prefer to attack the first open flower, staying in the flower until the petals fall off.

Sometimes, the infection remains localized in the flowers, but if it starts to spread then there is a serious problem on your hands. When it spreads in the wood, you will find pink to orange-red stripes under the bark.

Another sign is often a light tan to red, watery seepage that comes from infected parts of the tree, such as twigs, branches, and trunk cankers. Gradually, the ooze deepens after exposure to air. It leaves deep streaks on the tree.

The tips of the shoots rapidly wither away, causing the shepherd to become a rogue-like figure. The leaves on the twigs may turn black with the middle vein and veins before they are completely necrotic. Many diseased seedlings give the tree a burnt form.

The infection spreads to the rest of the tree, causing the flowers to turn brown. The twigs and flowers wither, shrink and turn black, then they turn at the ends. When it is time for the fire to spread and become severe, cankers are formed on the branches that leak.

Needless to say that flames are often fatal to trees and bushes. This bacteria is serious!

How to stop flames

Treatment of Agni Dosha is difficult, if not impossible, so prevention measures are extremely important. If you hear that someone in your area has a fire defect, make sure you are using these practices.

Choose resistant varieties

One thing you can do to prevent a fire defect from destroying your fruit trees is to choose resistant varieties. Many pear tree varieties, including Asiatic and Red pear, are susceptible to Agni dosha. Many varieties of apples are also susceptible, including Fuji, Gala, Golden Delicious, Granny Smith, Pink Lady, and Jonathan.

Try to plant varieties that are less likely to get scorched by fire. Infection begins in flowering, so trees that bloom late in the season often suffer more damage than other trees.

Avoid overhead irrigation

One of the most common ways of spreading bacteria is overhead watering. This causes infected soil and water to splatter on the leaves of the plant. It is one of the most common ways of spreading diseases and infections, so always pour water on the base of your trees or shrubs.

Clean garden tools

Another way that bacteria are spread is through gardening tools that have never been used on infected trees. The equipment needs to be sterilized in an alcohol or bleach solution. Make a solution of three parts denatured alcohol in one part water or one part household bleach in nine parts water.

To avoid rust, dry your tools thoroughly after washing them. Applying oil also helps.

Keep your trees healthy

These bacteria like to attack vulnerable or young trees. It is more likely to spread rapidly when susceptible trees are weakened, so it is important to keep your trees healthy. Agni Dosha is less likely to attack your tree and can cause major damage if it is healthy and strong.

Can you get rid of Agni dosha?

Unfortunately, there is no cure for Agni Dosha, but that does not mean that there are not some ways that you can try to slow the spread.

Prune trees and bushes

Experts recommend that you prune your trees and shrubs regularly and remove any infected trunks or branches on your tree. Removing the parts of your tree that are on fire helps to slow down the spread.

Removing diseased wood is best done in summer or winter when bacteria are not actively spreading throughout the tree. It spreads most frequently in spring and autumn, so pruning during the time that cankers are not growing anymore helps prevent spread.

However, if you notice infections spreading rapidly on susceptible trees, remove these branches as soon as the infection appears in the spring. Be sure to clean the pruning scissors with bleach between each cut.

Scrape the barkey

So, what do you do if the fire defect infection is on the trunk or major organ that you cannot bite? In infected areas it is possible to save the wood by scratching the bark to the cambium layer. This means that you need to remove the outer and inner bark.

Remove all discolored tissue beyond infection and six to eight inches more. It is best to do it in winter when trees and diseases are dormant. Do not apply any dressing to the wound.

Use bactericides

Another method that you can use, which can work as expected, is spraying bactericides on the trees. Some bactericides have been developed to fight fire defects, although they are not always effective.

Some gardeners use fixed copper products as a treatment for fire defects, but this method only reduces the bacteria’s ability to survive and breed. This will not necessarily eliminate it.

For the spray to work, they need to be applied to open flowers, so you will need several applications depending on the bloom period for your particular tree. When the flowers start opening, spray when the temperature does not go above 60 ° F.
