What are the Symptoms or Damage of Mites in the Trees?

Before knowing the solution of mites, one must know about spider mites in trees. Mites multiply very quickly, which is a serious problem since the symptoms or damage that can cause can become important. Therefore, it is necessary that we observe our trees daily in order to get rid of spider mites in trees.

Mite Symptoms in the tree
  • Stains on the leaves are somewhat more apparent in the beam than on the underside.
  • Yellowing bulges on the leaves.
  • Fruits malformed.
  • The flowers abort and fall.
  • Appearance of cobwebs.
Mite Damage in the trees

Mites pose a threat to the host plant because it feeds on the cellular contents of the leaves, absorbing them cell by cell, leaving a light and pale circular spot that contrasts with the green of the epidermis of the leaf. Although individually the lesions are very small, as mites live in very large colonies, a plant can attack hundreds or thousands of these mites, they cause thousands of injuries, so they really do produce great damage.

These pickets, which are detected as small yellow spots, can suppose an important reduction of the photosynthesis of the plant; this greatly reduces the production of nutrients, sometimes even killing the plant.

These attacks can produce intense and sudden defoliation, especially in summer. Also in milder attacks produce discoloration of the leaves due to the number of pickets (top picture). It is generally at this moment that we realize that we have mites. Thus it is better that before reaching this point we detect the mites. We can only do it by watching our bonsai with a magnifying glass and looking at the underside of the leaves, where the mites and bark are located to detect the eggs.

The combination of strong attacks of red mite with low environmental humidity and wind (west), or deficient moisture content in the plant due to dry soil or poor root system, can cause heavy defoliation, especially in the most exposed parts of the tree.

The damages differ with relative ease from those produced by the red spider, because the discoloration of the leaves is total while in the case of the red spider it is limited to the area occupied by the colony. So to avoid this damage, one must know how to control of spider mites in the trees.

What to Do to Control or Fight Them?

In order to perform spider-mite control, you need to know about spider mites in the trees if there are any on your trees. Firstly, you need to investigate the leaves of the trees and plants carefully to see if you can spot any yellow or brown colored stains on it.

Once you are well assured that you have spotted spider mites on the trees, it is time for you to get ready with all the hacks and weapons to control of spider mites in trees. So here are a few ways which you can adopt to get rid of them.

  • Cultural control. It is recommended to prune (burn damaged branches and leaves). If the branches and leaves are left lying on the ground, the mites disperse to other trees. Clean tools and machinery used in an infested garden.
  • Biologic control. The main natural enemies of these pests are mites that belong to the Phytoseiidae family. Which have a predatory action that can reduce populations of phytophagous mites and can do the control of spider mites in trees.
  • Biorational control. Several formulations of plant extracts based on neem, garlic, chili, cinnamon can help in the management of mites, due to its repellent and dissuasive effect of feeding.

Choose the products whose active ingredients are mostly natural essential oils like those that we have mentioned above. Spider mites tend to develop quick immunities towards your usual pesticides, so you will end up killing insects that prey on spider mites.

What are the Ecological Remedies?

  • Yellow adhesive traps: They are placed near the plants so that the mites, which adore the yellow colour, cannot resist the temptation to go towards them. Once they come in contact, they will stay stuck.
  • Garlic: We boil two litres of water with a head of crushed garlic and then let it macerate for 8 to 12 hours. Then, we strain it and fill a sprayer with the resulting liquid and then spray the leaves with it.
  • Dry nettles: We collect 100 grams and put them to boil in 1L of water. When it has cooled down, we fill a sprayer and treat the trees.
  • Onion skin: We cut it and spread it around the trees.
  • Removal of infested parts: Another way to control the spider mite infestation is the removal of the infested leaves and stem in order to prevent the trees from further infestation.
  • Water spray: You can also spray water on the infected part of the trees so that the spider mites lose their grip and fall off. You can also wipe the indoor plants using a wet sponge and maintain it as a regular habit so that these spider mites don’t get a chance to infect your plants.
