Infiltrate in the garden under various guises, often confusing his own gardeners who can not always distinguish the symptoms of major diseases affecting plants, bacteria, fungi and viruses. This trio attacks plants with and without flowers, but they differ in one respect - a perfectly fungus survives in soil as a bacterium or virus needs a host plant to survive.

Causes

Fungi

It is estimated that 70% of the major plant diseases are caused by fungi - tiny organisms (only visible under a microscope!) Which produce large quantities of spores (the cells that break off and fall, without fertilization, to form new cells) , which are propagated rapidly due to wind, water, insects or animals. There are over 10,000 kinds of fungi that are unable to penetrate the cuticle and the epidermis (the strongest barriers of a plant), attack the most sensitive areas - the shoots or areas already damaged by insects. A plant infected may release up to 100 million spores, a quantity difficult to control, in that rapidly degrade the plant cell, producing at the same time toxins that interfere with the full operation of its body. Fungi are also difficult to remove because they can remain dormant in the soil, plant residues which are decomposed or a healthy plant, waiting for the weather conditions ideal for re-contamination.

Virus

Still smaller than bacteria, viruses can only reproduce from the cells of the plant itself.Leaking into the plant or from leaves of the foot, usually in areas already injured by insects, but need a means of transport, which can be an insect, pollen or seeds some infected. Once infiltrate the (s), viruses, and plants may be attacked by more than one virus simultaneously moves through the vessels vascular disease causing organism infecting the plant.

Bacteria

The plant diseases caused by bacteria are less frequent, for a simple reason - to grow and multiply bacteria require water and heat. Therefore, they are more dependent on hot and humid climates to contaminate the plants. Transported by water, insects or animals, bacteria infiltrate through a cut flower or a leaf or foot, may cause damage from a purely superficial, the wilting or even death.

Nutritional Deficiencies

Sometimes the disease of a plant is not due to bacteria, fungi and viruses, but the poor diet. If leaves have pale or yellowish vascular vessels, may be a sign that she is suffering from nutritional deficiencies. In this case, the remedy is called "a good fertilizer," appropriate to the plant in question.

Symptoms

A sick plant has several changes in its metabolism, color, and anatomy of different organs, and it can start producing abnormal substances.
Some signs warning are: downy mildew (white powder); mold gray or black, rust colored bubbles, a black body or growth; black spots, and the appearance of yeast fungi, among others.

Cures

With plans to require "medical attention", it is clear that instinct tells you to go running to seek your faithful friend the "pesticide." However, because it is a product with extremely potent chemicals, which unfortunately in doing one thing well are polluting the environment, it is best to consider all other possible options. Here´s some help:

There are "symptoms" that strange looking very serious and can be purely ephemeral, disappearing within a few days or when the weather improves. Look out!

Sometimes simply remove the flowers, buds, leaves and / or infected feet to eliminate the problem. Do not take advantage of these residues for composting, dispose of them immediately!

As a last resort, refer to pesticides appropriate solution by choosing a low toxicity.Follow the instructions carefully and remember it will not solve the situation by spraying the entire contents of a container plant on a poor sick - but may, ultimately intensify their problem with the death of the plant, and even neighboring plants ground!

Prevention is key to a garden that breathes health. Want to know what to do? Start with a healthy soil, because this land produces healthy plants with health and healthy plants can resist more easily to disease. A soil quality should be loam and enriched with fertilizer and composting techniques.

Maintain its free garden weed and plant wastes, which are elements conducive to the development of all kinds of diseases.

The diseases are often transmitted from plant to plant due to unwashed utensils garden.Ensure that all tools are properly disinfected (especially when used to cut or eliminate sick leaves and other parts), simply a mixture of water and bleach.

During the process of watering, be careful not to splash the foliage of plants. By splashing the soil to the leaves, is putting them at risk of contracting a disease. If possible, water early in the morning so plants have time to dry before the peak of the sun that can burn plants very seriously wet. Moreover, the longer are wet sheets, are more likely to be attacked by bacteria, fungi and viruses.

It is also important to allow good air circulation between all plants. In addition to dry faster, the windscreen can easily carry the diseases away before they have time to "stick" to a plant.
If you find that, year after year, the same symptoms and diseases continue to devastate your garden, you´d better start thinking about new varieties of plants and flowers.

When purchasing new plants, inspect them thoroughly before the take-home or opt for varieties that are self-proclaimed and which are, in fact, disease resistant plants.

Finally, when in doubt consult a specialist or get a guide on the different bacterial, viral and fungal infections, as well as their treatment, to assist in situations less healthy!

Basically, better safe than sorry ... for a garden resplendent!
