Fight pear grid

The Content Of The Article:

The pear tree is one of the robust and easy-care fruit tree species. Due to its beautiful and delicious fruits, the pear tree is being planted more and more often in the house garden. However, the strong-looking tree can quickly develop a typical fungal infection. Occurring pear grid can damage and strain the leaves of the pear tree. Since the disease promotes rapid infection, the tree needs quick care and treatment. In addition, with proper precaution the disease of the pear tree can be avoided and prevented.
Properly interpret the symptoms and causes of the disease
The disease, which usually occurs in spring, manifests itself with orange-red spots and wart-like thickenings below the leaves. These irregular discolorations are clear symptoms and signs of pear grid rust. The responsible fungus spreads quickly and can completely infect the tree in a short time. The pear grid is considered a vagabond among the mushroom varieties. Mostly, the disease initially attacks simple and abundant juniper species. These are in turn provided with discoloration and wart-like thickening. The growths form the spores and pathogens of the disease. The pathogen is extremely resistant and survives even in winter. During the wintering period, the fungus remains unnoticed and quiet on the various juniper plants. Only in spring the disease gradually attacks the trees.
These in turn develop and spread traces and thus continue the cycle. The distribution and transmission of the spores takes place via the wind. The pathogens can spread in strong winds up to 500 meters in the environment and thus attack all the leaves of the pear tree within a very short time. In addition, wasps and other insects can spread the spores and in good weather conditions favor an explosive spread of the fungus. The pear tree is exposed to increased stress by the disease. Young pear trees can take serious damage and be disturbed in their development. In addition, the disease can lead untreated to the death of the tree.
The treatment of infested trees
Diseased trees can be treated with special sprays from specialist retailers. It is important to observe the prescribed times, intervals and concentration of the preparation. Nursing or horsetail biologicals can also stop the infestation and relieve the disease. These special biological plant broths can be made by yourself or purchased from specialist dealers. In order to prevent further spread of the pathogens, infested leaves, trees and shrubs should be removed or cut off. It is important to recognize the infestation at an early stage and counteract it. In addition, the causative agents and disseminators of the fungal disease must be treated or eliminated. Despite a fungal attack, there is no risk of eating the fruits, as the fungus only damages the leaves.
Prevention of the development and spread of the pear grid
The pear grid uses various juniper species as an intermediate host and overwintering point. In the process, all juniper plants of the own garden should be removed and sick shoots should be cut off correctly. The resulting waste should be carefully removed to prevent re-emergence of the fungus. This provides little protection against the spread and development of spores. In addition, the fruit tree can be treated early and regularly with plant strengthening agents. This prevents the development of the disease and strengthens the tree as a precaution. Basically strong and strong trees are less prone to fungal attack. Thus, care should be taken to support the pear tree in its development. Regular care can reduce the onset of the disease. The addition of nutrients, humus, mulch or other important elements can strengthen the soil and the tree and provide additional protection.
Hints and tips about the fungal attack and the pear tree
There are different varieties of pear trees, all of which react differently to the fungus. When buying a new pear tree you can choose between many different species and varieties. An exact consultation in the specialized trade or garden center can provide exact information about the different kinds of the young trees.
The pear grid should not be underestimated, as the spread of the pathogen can progress rapidly and damage a complete tree population. However, sufficient and regular care of the fruit tree can prematurely reject or combat the fungus. With proper care and handling nothing stands in the way of the next profitable harvest.
Worth knowing about the pear grid
But where does this plant disease come from? Well, it is triggered by pathogens, the rust fungus. Juniper bushes formed so-called fungal spores, which become visible on the branches. When it rains, they swell up and are therefore even more observable.They are recognizable by orange-red cones. The wind carries the spores then over to the pear trees, which represent the Nebenwirt. Mushroom spores take only a few hours to penetrate the leaves. Mostly the time of the transfer is in May. It is favorable, if in the three months March to May no rain falls. Then you have the chance that the spores shrink so slowly. However, a problem remains. Once the juniper shrubs have been infested and thus infected, there is always a spore focus. This cycle, spores of juniper shrub are transferred to the pear trees, etc., can always be repeated as long as the main host is not eliminated.
What can you do about breaking this cycle? Since the main source of juniper is, you drive the cheapest by eliminating the entire shrubs. However, particularly susceptible and less susceptible varieties should be distinguished. Of course, this is not possible as a layman. Therefore, a professional, species-specific determination of juniper would be very useful. However, this effort is also quite difficult. If you want to be completely sure you do not want these shrubs. There are certainly similar plants that are not affected by such pests. It should be considered, however, that in the green areas of the neighborhood possibly juniper stands. These could be infested, and thus the danger of transmission into the own garden is not completely eliminated.
