Fungi on apple trees

July 29, 2011

The basis for having productive apple trees is to provide them a healthy growing environment, including nutrients, proper sun exposure and enough water. Among the most important conditions, there are clean, clear leaves, without any fungal infection. Fungi on apple trees can ruin the crop, but also the overall appearance of a tree. Sometimes, the disease can even kill the apple tree, so fungal infections are a serious problem.



You can diagnose fungi on apple trees according to certain symptoms. If the leaves feature brown, black or reddish spots and they are raised or fuzzy, the apple tree is likely to be infected. Also the presence of a whitish covering on the leaves is a symptom of fungal infection, as well as twisted, small leaves, distorted fruit or stunted growth. Pay attention to every change in the healthy aspect of the tree and act if something is wrong.

Fungi on apple trees are encouraged to grow during wet, warm weather throughout the year, because these weather conditions make it easier for fungi to take root on the tree. Generally, they install in certain wounds left by insects, storms or other physical damages. Fungal diseases can be carried by pests such as aphids, brought by the wind, or growing in the ground.

There are two ways to control fungal disease: cultural or chemical control. Taking in account that chemicals are expensive and they can harm the apple tree, try to keep under control the fungal problem through some current maintaining procedures. Throw away all fallen leaves and apples so that they not attract fungi to the garden and lawn. Also do not let standing water around the apple tree, because it can easily host fungi during spring and summer days.

Even if chemicals can negatively affect the environment, correct use according to the instructions can diminish the possibility of fungi on apple trees, but also on the rest on the garden. Fungicides kill all fungal spores, visible and invisible to the naked eye, while stopping the disease from infecting the plant later.
