4 Pear Tree Pests
Pear pests can range from uninhibited to seriously harmful. Pests that don’t affect your crop can spread disease, so you still need to keep them under control.
Aphids seem to like to infest all kinds of plants, including pear trees. These tiny insects form clusters on the underside of leaves, sucking the sap and leaving behind a secretion called honeydew. This leaves a growth medium for sooty mold on your pear trees.
Usually, aphids infestations are not a big deal until they get out of hand. You can drop them from the tree with a jet of water from your hose. Neem oil or other insecticidal oils kill eggs; Many insecticides work for aphids.

2. Coding Moth
Ever heard of Coding Moth? Most people do not know about these pests of pears, but they cause great damage to fruit trees. They like to poke and pierce the fruits of pears; These pores are often blocked by brown debris (insect excrement). Some holes are shallow, but others burrow deeper into the fruit, reaching the core.
It is important to understand the lifecycle of the coding moth; They produce up to four generations per year. Therefore, they easily infect your garden. The larvae do the most damage to your pear trees.
Preventive measures are essential, so make sure you learn proper fruit tree care techniques. Pear trees should be pruned so that their canopy remains open. You can also use Entrust and kaolin clay applications to treat these pests.
Most home gardeners opt to remove infected fruits by hand before the larvae leave fruit. This is an easy way to reduce the population. If you see an infected fruit, throw it out or burn it to prevent it from moving on to the next one!
These insects wrap the leaves of the pear tree and tie it with a silky webbing. Again, Leaflet – clever name, isn’t it? – Feed off damaged, rolled leaves, which cause discoloration of your fruit tree.
You may also see silk webbing on the fruit, and can be scorched by the damage of eating the fruit. Larvae cause the most damage to pear trees, so monitor for any signs of adult pests in your garden.
If you end up with an infestation of leafrollers on your pear tree, Entrust or . use bacillus thuringiensis. These are effective, biological treatment options. Make sure you spray carefully; It needs to go inside the rolled leaves where the larvae like to hide and feed.
4. Pear Psylla
One pest of pear trees that is known to cause serious problems is pear psylla. It is a harmful pest to pear trees, and it is known to develop resistance to most insecticide options. An infestation causes rapid and overall reduced tree vigor, eventually killing the tree with a disease called pear drop.
If you end up with pear psylla pests in your garden, use insecticidal oil and kaolin soil to get rid of the population. It is generally best to spray during the dormant season because pear psylla likes to overwinter on trees. If you catch them while they’re dormant, it’s easy to get rid of them.
7 Pear Tree Diseases
There are many diseases that can cause serious problems. The sooner you detect the problem, the easier it is to treat it. There are concerns here.
1. Armillaria Root Rot
Armillaria root rot is a fungal disease that leads to a number of problems, including plant death. Symptoms of this disease usually begin with small, discolored leaves that quickly drop from the plant. You may notice branches falling off your plant or clusters of armillaria mushrooms at the base.
Unfortunately, armillaria root rot cannot be controlled once it has taken over your pear trees. You will need to completely remove diseased or dead plants, including all roots. If you leave the dead roots in the soil, the fungus survives. The best way to prevent armillaria root rot is to plant resistant rootstocks.
Blast is a bacterial disease that prefers cool, wet weather. It begins with the formation of water-soaked or black lesions on the leaf stalks that rapidly spread along the central vein. The leaves of the plant will turn black and die. The blast also causes cankers on the twigs and branches, and they often die.
Due to this bacterial disease, black spots also appear on the fruits of pears.
If the disease is severe, copper fungicides can be applied to fruit trees in the fall and winter. You may need several applications to get rid of the disease.
3. Crown, Collar and Root Rot
Although it is not as common as some other diseases, your pear tree may be suffering from crown, collar or root rot. Crown rot occurs in the rootstock bark tissue, whereas root rot affects the roots. Collar rot affects the descending part of the tree (the part above the graft joint).
The disease usually emerges when you have poorly drained soil and standing water around your pear tree. It is caused by the bacterium Phytophthora.
Crown, collar and root rot cause the leaves on your tree to wither, but they will remain attached. You will notice that tree growth is reduced, and there may be cankers on the stem at soil level. The bark will discolor and become sticky when wet.
Unfortunately, no treatment for these rots is effective. Prevention is the best option, which includes proper water management and never overwatering your pear trees.
4. Fire defect
Most fruit tree owners have heard of fires; This is one of the more dreaded pear tree diseases. It infects a range of fruit trees and shrubs. This bacterial disease causes the shoots and flowers on your fruit tree to wither and turn black. The plant seems to have been scorched by fire, hence the name.
Agni dosha prefers hot, rainy days when the fruit trees are in bloom. If you find that your pear tree is on fire, you need to remove all diseased wood and treat your fruit tree with a Bordeaux mixture or an approved copper treatment. These can help prevent the spread of disease.

5. Pear Fall
Pear drop is a phytoplasma disease that is spread by the pear psylla moth. This causes poor seedling development and the death of shoots on your tree. You will notice premature leaf drop as well as reddening and rolling of the upper leaves under the canopy of your pear tree. Pear fall also reduces the size of foliage and fruit on your tree.
It is not possible to get rid of pear fall on your trees. No treatment is really effective. Your best option is to plant resistant or tolerant rootstocks and control pear psylla on your trees.
If you see yellow or chlorotic spots on the leaves of your pear tree, you may have scab. Scab is a fungal disease that causes many symptoms, such as yellow or dark green spots on the leaves and fruits of your tree. You may have a velvety growth on the undersides of your leaves.
Scab also causes twisted or distorted leaves. A severe infestation will cause your tree’s leaves to turn yellow and drop. Unfortunately, this fungus overwinters on dead foliage in the ground, and since the spores are spread by wind, the disease is often difficult to get rid of.
Prevention is always the first line of defense, but if your pear trees end up with scabs anyway, try a fungicide application, such as copper soap or Bordeaux mixture. Make sure you always remove all fallen leaves from the area and consider adding a fungicide to areas near your pear trees where the leaves are wet for long periods.
7. Septoria Leaf Spot
Septoria leaf spot is a fungal disease that is common on pear trees. It is one of the most devastating fungal problems, and it loves areas that are wet and humid for long periods of time. This fungus grows on infected debris, so removing fallen leaves is essential if you grow any type of fruit tree.
This infection mainly resides on the leaves and upper surface of the leaves. You may see grayish-white spots with purple margins that become better defined at maturity. As the disease progresses, it causes leaves to drop from the pear tree in late summer.
