Pear trees growing in our gardens can be attacked by various pathogens causing leaf damage. A very common cause of leaf tissue damage ispear leaf pests , such as pear aphid, pear midge or pear - pear and pear. See how to identify the most commonpear leaf pestsand how to combat them.
Pear leaf pests. Pear aphid causes curling and deformation of leaves.
During the vegetative senon, various disturbing damage to pear leaves, such as spots, growths or bulges, can be observed. Often then it is suspected that the pear tree is sick, while the perpetrators of this damage may bepear leaf pestsIt is worth learning to recognize them and distinguish them from pear diseases.
Reddish pear honey
Reddish pear meadis a double-winged bug from the honeysuckle family, 4.5 mm long. In summer, the bodies of pests are intensely orange, and after winter they are brown-red. In early spring, adult honeysuckle suck the juice from young leaves, causing them to stun growth and distort them. Foraging on older leaves leads to wrinkling of the leaf blades. The larvae initially feed on the leaves and then move to the shoots.

On the plots, you usually do not need to combat this honeybug because its number effectively reduces the bug of the tasznikowidae family. For possible pear spraying after the detection of the pest in the growing season, you can use the natural preparation Agrocover, a natural preparation, useful in the control of many different aphids. It is worth noting here that the describedreddish pear honeyis not the only pear honeysuckle, but all pear honeysuckle cause similar damage to plants and we fight them in the same way.
Pryszczarek pearowiec
Pryszczarek pearis a flycatcher from the midge family, approx. 2 mm long. It looks like a mosquito. As a result of feeding the midge larvae, the youngest leaves at the ends of the shoots and root suckers do not develop, and their edges rolled inwards are thick and brittle. They turn black after some time. Inside the distorted leaves are numerous white larvae.In order to reduce the occurrence of the pear-tree midge, it is necessary to remove and destroy the root suckers and unnecessary shoots growing from the trunk, which most often have deformed leaves. For possible chemical control of this pear pest, the preparation Mospilan 20 SP is used.
Pear leaf pests. Brownish blisters and leaf deformation
may indicate that the plant is attacked by a pear skin
Pear skin
Pear skinis a mite from the spotted family, invisible to the naked eye. Numerous yellowish blisters appear on the surface of the affected leaves, turning brown after some time. The feeding of the hypoderm is especially dangerous for young trees, the growth of which may be inhibited. In order to reduce the occurrence of the pear skin, the infected leaves should be systematically removed in May and June. If we do not do it after a few years, it may take over the entire tree, inhibiting its growth and fruiting.Chemicaltreatment of the pear skinis performed in the green and white bud phase, usually in March / April, with Bulldock 025 EC and Ortus 05 SC.
Pear Lumberjack
Pear Wanderingis also a mite from the spotted family. It feeds in groups on the underside of the leaves, causing the leaf blades to bend and their edges to wrinkle. Russians may appear on the underside of the leaves and on the fruit. The control of this pear pest in allotment and home gardens is not necessary due to its low harmfulness. Possible chemical treatment in early spring, as in the case of the above-described pear skin, is mainly performed in production orchards.
Pear leaf rollers
In early spring, green caterpillars with dark heads can be seen on young leaves, flower buds and flowers.These arecaterpillars of the leaf rollers , which later contribute to the rolling of the leaves into a tube shape. The name of this group of pests comes from the characteristic appearance of the curled leaves. They can be found on pears, among others. Beetle tortrix, rose tortrix and retina tortrix.

The caterpillars of the rollers produce yarn that clumps leaves together to form loose rosettes. They can also scrape the crumb from the leaves, which creates characteristic openings in the leaf blades.After spotting leaf roller caterpillars on a pearspray with the biological preparation Lepinox Plus. It is an ecological agent, safe for the environment and harmless to beneficial insects. Ideal forfighting caterpillars on pear leavesin garden crops.
