When you are lucky enough to have a green space on your property, you might as well take care of it. You think that a yellowed leaf is not very serious? Think again! It’s the beginning of a disease that you’d better follow closely in order to avoid harmful propagation for your plants. This article gathered 4 diseases that can affect fruit trees, roses, and vegetables.
This disease is classified as cryptogamic and occurs when the humidity level on the leaves is too high. It develops mainly in spring and fall. However, the summer period, during which there is heavy rainfall, is also favorable to the spread of this disease.
The proliferation of fungi in humid environments particularly causes anthracnose. When leaves and grains are affected by this disease, brown spots with black spots appear.
To prevent the development of anthracnose, it is necessary to remove the affected leaves and fruits and burn them. Spraying comfrey or nettle, or garlic solution on the trees remains the effective prevention against this disease.
2. Cabbage looper
Cabbage looper is one of the fungal diseases that can affect the vegetable. This disease is caused by fungi in the soil. Plants of the brassica type are also prey for it.
In the presence of cabbage looper, plants and vegetables are slow to develop. In fact, it is particularly the main roots and the crown that is most affected. In addition, their leaves wilt and turn yellow.
In order to prevent this disease, gardening specialists recommend the practice of crop rotation (every 7 years) as well as the cultivation of trap plants (cocksfoot, poppy, nasturtium…). These plants trigger the germination of spores. It is also important to ensure that the soil is well drained to eliminate excess water that is conducive to the propagation of the fungi.
3. Late blight
Almost all plants can be contaminated by mildew. However, we can distinguish grapevines, tomatoes, potatoes, squash, and lettuce. It is a cryptogamic disease caused by pseudo-fungi. Heavy rainfall or excessive watering on the leaves are the triggering factors. Initially, the foliage shows brown spots or white, cottony molds. As the disease develops, the leaves eventually wilt.
So, as you would have noticed, an overly humid environment is conducive to late blight. As a preventative measure, then, avoid wetting the foliage when watering your plants. Do it only at the root level. When some leaves are already affected, they must be quickly removed. Treatment with garlic manure and mulching is also effective.
Fruit trees are particularly affected by moniliasis. Trees are particularly affected by moniliasis. This is why it is also called “fruit rot”. Here again, moniliasis is a fungal disease caused by excess moisture. It usually develops during the spring season, i.e., at the time of flowering.
The fungi ” Monilia fructigena ” and ” Monilia laxa “attacked flowers, fruits, and leaves. The drying of the leaves characterizes Monilia, then the withering of the branches. Then, the fruits undergo mummification on the branch and end up rotting.
To avoid the development of the disease on other trees, fruits, flowers, or leaves, it is necessary to remove as soon as possible those already affected. If there is too much fruit crowding the trees, call a tree pruner to thin the trees. The goal is to limit contact and subsequent contamination between the fruits. If you decide to prune the fruit yourself, don’t forget to disinfect your tools. Finally, to prevent moniliasis, use an infusion of horseradish or horsetail.
