Why Is My Fruit Tree Dying? Common Fruit Tree Pests and Diseases

Adding fruit trees to your property is a great way to grow more food and add beauty. Before you dive into this world, make sure that you know the pests and diseases of the mango fruit tree that you may encounter.

While some pests infect both vegetative plants and fruit trees, some pests and diseases are specific to these trees. Preventive methods are essential for pests and diseases; When they infect your plants, it is always easier to prevent problems than to treat them.

Do not worry! If you know what damage can happen to your tree, then you can be ready to face the problems of these mango fruit trees.

Mango Fruit Tree Pest

Dealing with the problems of these mango fruit trees is frustrating, but most have effective methods of treatment. Always practice good fruit trees such as pruning and debris cleaning to keep away bacteria and fungal infections. If your tree is infected, make sure you correctly identify the problem to find the right treatment.

Let’s look at some of the most common fruit tree pests. This list is far from exhaustive, but these are some of the most destructive and common insects you can find on your trees.

Apple maggots

As the name suggests, apple maggots appear in infected apple trees, usually in early July to September. Adult apple maggots remain in the soil until July, emerging under the skin of the apple and laying eggs. The larvae feed on the fruits, leading to pus and mihapen fruits.

Prevention methods work well for keeping apple maggots outside your garden. Pick up any apples that fall during the growing season and hang sticky traps around their trees to catch adult females before laying eggs on the fruit.

If you end up with an infection of Apple maggots, insecticides are effective against these pests, especially those containing spinosad. You have to spray the trees several times to eliminate them, usually three or four times per season.

Peachtree Borer

Without a doubt, peach borers are the most destructive pests of peaches, cherries, plum and other stone fruits. The most damage is caused by immature larvae that chew under the bark of the lower proboscis and larger roots. These pests cause widespread wounds, weakening and killing of trees.

If you have an infection of peach borers, it is necessary to take quick action. Pesticides are effective and new eggs need to be planted on the lower trunk to prevent them from hatching and causing infection. The spray should target the egg and larval stages; Once the larvae move into the tree, sprays are not effective.

Psyllids

Psyllids are sometimes called plant lice, and are small, sap-sucking insects that like to feed on fruit trees and members of a closely related family. There are more than 100 species of psyllids, but they all enter the plant tissue, sucking up the nutrient dense liquid. Then, they spread honey, a sweet substance, on top of the tree which attracts ants.

Psyllids are one of the top fruit tree problems when the infection grows to a large size. Broad-spectrum insecticides work and keep beneficial pests living in your garden. Neem oil and pesticide soap are also effective in killing most psyllids. Pruning does not work because these pests are mobile and simply move from branch to branch.

Scale insects

Scale insects are one of the most serious fruit tree problems that infect peach, nectar, apple, pear, cherry and plum trees. These insects feed on the bark, leaves and fruits of the plant and cause fruit growth and fruit sores. Severe infection branches or whole trees die if left untreated.

Spraying fruit trees with horticultural oils is an effective option, as it kills scales with other soft bodied insects. Horticultural oils are safe for organic gardens and will not harm beneficial pests.

Savli larva

The larvae of saws are often called cherry or pear slugs, and they are a common fruit tree problem throughout the United States and Canada. They infect mountain ashes, hawthorn, cherries, plum and pear trees. Small populations are not usually an issue, but largely destroy entire fruit trees.

The adults deposit eggs in the arachnid leaves, and when they emerge, they begin to eat the leaves. Most gardeners wash saws with pesticide soap or apply food-grade diatomaceous earth on leaves.

If you end a major violation, a pesticide spray that contains spinosad will be an effective option. Botanical insecticides should be a last resort method as they have harmful effects.

Winter Moth Caterpillar

Winter moth caterpillar is a destructive insect that attacks fruit trees such as cherries, apples, and crabapple trees.

Unlike other pests, problems appear quickly in the spring. This is because adult moths lay eggs in the bark crack of the tree in late fall and winter. The eggs hatch in the spring, and the larvae quickly start spoiling entire fruit trees.

The best way to treat winter insect hull is by spraying Bt (Bacillus thuringiensis) On their trees. Bt is a naturally occurring bacteria that prevents pests from feeding and dying. Use this as early as possible in the spring to prevent these pests before munching your trees.

Mango Fruit Tree Disease

Frustration is caused by diseases of the fruit tree. There are many soil-borne diseases that you may not know are present in your soil while your trees are dying. Here are some diseases of the most common fruit tree.

Bacterial bowel

Bacterial canker is a disease that takes on any fruit tree that you can grow on your property. The most common symptom is holes that appear in the leaves and on new shoots. Eventually, the bacterial canker infects the entire branch, eventually dying completely.

The disease of this fruit tree is most commonly found in stone fruit trees and trees that have previous frost damage. If you think it is infecting your trees, cut branches several inches below the infected area. Apply a fungicide on your tree every two weeks to help eradicate the disease.

Brown rot

Brown rot is a fruit tree disease that affects many different trees, such as peaches, nectarines, plums, cherries, apples, apricots, and pears. This causes the stems, flowers, and fruit to cover in the brown fungus that mummifies the fruit. Once you know what brown rot looks like, it’s easy

Remove any affected parts of the tree and fruit to try to slow down the fungal spread. Allow fruit trees to have more sunlight and air circulation to prevent fungi from being carried to the tree.

Cherry Leaf Spot

Cherry leaf spot is a fungal disease that affects all types of cherry trees, but it is most preferred to tart cherries. It begins with purple spots on the leaves that seem innocent at first, but it progresses quickly until all the leaves are dead, ending the tree in its entirety.

The disease remains on the leaves throughout the winter, so it is important that you clean out any debris that may have originated from that tree. You can also use a fungicide spray to keep the disease under control.

Crown gall

Crown gulls are caused by soil-borne bacteria, and are most common on apple, cherry, peach, and plum trees.

The problem starts when there is some kind of wound in your tree, and bacteria find their way into the wound. Over time the lanes become smaller and develop on a larger scale.

Prevention is important for crown gall because it is difficult to get this bacteria out of the soil. Chances are, you won’t know that the bacteria is in the soil until it shows up on your tree. Sterilizing equipment before working on your fruit trees helps prevent spread, because once a tree is crowned, bacteria remain throughout the tree.

Fire blight

Agni Dosha is a bacterial disease that attacks apple, crabapple and pear trees. It is most common in the Mid-Atlantic region, but it also occurs in other regions.

The disease gained its name because it made the leaves look as if they were burnt. They become yellow or orange and gradually turn brown and black and dry up.

It is possible to cure Agni Dosha, but when the disease does not spread very far, it is easy to treat it. The best treatment options are copper, and antibiotic sprays for fruit trees, but prevention is important. Avoid applying too much nitrogen when fertilizing disease-resistant varieties of plants and your fruit trees.

Peach Scab

Despite the name, peach scab is more infected than just peach trees; It is also common on nectar and apricot trees. Peach scab is a fungal disease that affects twigs, leaves and fruits on trees.

Prevention is the best method for peach scab. Make sure you prick your trees well to increase air flow between branches, reducing the chance of fungal infection. The fungus loves warm, moist areas without the flow of air, so you need to dehumanize the environment.

If you end up with peach crust, the best course of action is to try spraying a fungicidal spray. These sprays need to be applied to the petals until they fall one month before harvest. Spray on trees every 10-14 days to be most effective.
