Pear Tree Pests and Diseases
Just like apple (but to a lesser extent), pear is a delicious fruit that unfortunately does not attract only humans. Aphids, moths, beetles, leafhoppers and spider mites often attack the tree and the fruits in order to lay their eggs and be fed. The common denominator of these pests is that they lay their eggs in various parts of the tree or the fruit and they often cause spots or holes to the fruit, fruit drop and damage to the leaves, from curling and yellowing to defoliation.
A major fungal disease that causes severe economic damage to commercial pear and apple growers is Powdery Mildew. The pathogen (Podosphaera leucotricha) attacks flowers, leaves and fruits, causing fruit distortion and discoloration, while the quantity of the fruits decreases. Moreover, the infected tree becomes weak and is more vulnerable to other attacks. Read more on Powdery Mildew
Fire Blight is a bacterial disease caused by Erwinia amylovora. It can be widely spread in pear and apple orchards with wet and warm climate. As its name reveals, fire blight finally makes the shoots and branches look like they are burned. It mainly affects young shoots and can be faced by pruning only when the tree is dormancy. Pruning during active growth will most likely spread the disease (ask a certified agronomist). Read more on Fire Blight
Crown rot, collar rot and root rot are also common pear tree diseases.
