Pests and Diseases of Apple Tree

Any fruit tree and specifically the apple tree is prone to attracting both pests and diseases. Without adequate control of these pathogens, an unsuccessful harvest with affected fruits results.

Here we are going to help you to recognize the main pests and diseases of the apple tree.

 

MAIN PESTS OF THE APPLE TREE

MITES

They are usually very small, around 0.5 mm, red in color, with white bumps (a way to distinguish it from other spiders). There are two very polyphagous species, ( Panonychus ulmi, Tetr anychus urticae ). The damage caused by these mites is characteristic of the leaves and shoots, caused by bites. Over time, the general weakening of the fruit tree and the defoliation of the leaves occurs.

The treatment for this pest consists of the application of insecticides-acaricides (1.8% w / v of Abamectin) at a rate of 8 ml of product per 10 L of water, in foliar application.

CARCOCAPSA

The carcocapsa usually measures between 1.5 and 2 cm, the male being smaller than the female. The damage produced in the pear tree consists of holes in the fruit, causing the destruction and non-commercialization of these.

FRUIT FLY

The activity of the fruit fly begins in spring with the arrival of the heat. The damage occurs in the fruit, by the bite of the female. It produces holes that turn from yellow to brown.

SAN JOSE LOUSE

This pest develops in late winter after hibernation. With the arrival of the heat (fortnight in May) the plague is visually observed. They cause damage to the fruits, reducing their commercialization. They present purplish spots on the leaves or on the veins of the leaves and reddish circular pits in fruits.

MAIN DISEASES OF THE APPLE TREE

SPOTTED (V ENTURIA INAQUALIS)

The damage begins with the formation of spots on the olive green leaves, turning black over time. If the disease is severe, defoliation of the tree occurs. These spots also appear on the fruits, depreciating them commercially.
