DISEASES OF PLANTS
Plants like all living things can be affected by numerous diseases, sometimes even serious ones, for this reason it is always better to resort to preventive care to defend them from numerous attacks. As soon as we see that one of our beloved plants has been affected by a disease, we must first identify the symptoms so that we can link them to the type of disease, in order to proceed with a specific treatment. If affected by bacteria, the plant's tissues die, to the point of bringing it to the inevitable fate, this disease can be fought with copper-based products. If the plant has been subjected to water stagnation or excessive humidity, it can undergo the annoying and unsightly Gray Mold, in this case fungicide products must be used. if the plant shows dark spots it could be due to rust due to an environment that is too hot and with a high level of humidity. To keep in mind that too humid environments can also cause collar pain, the symptoms of this pathology are understood through the leaves that tend to wither very quickly and at the same time the roots start to rot, Another known pathology is the so-called Rogna, caused by very powerful bacteria, in fact deadly, in this case all that remains is to eradicate the affected plant so as not to run the risk of infecting other pests nearby. While there is a type of fungus that is able to create a mold called Peronospora, the latter mainly attacks the leaves and can be fought with copper-based treatments. Finally, there are more serious diseases that can affect plants such as Fusariosi and Verticillosi, always caused by fungi that can bring plants to death. Plants can also become sick due to insects, in fact some pathologies take the name of the infecting agent. The most common parasites capable of attacking plants are the common mites, aphids, cochineals, thrips, white fly, bedbug and many others with vine Ozorhynchus.
DISEASES CAUSED BY CLIMATE
Plants can also get sick due to the climate and the environment in which they are grown. First you need to choose the plants to grow, based on the temperature to which the chosen area for cultivation is subjected, without distinguishing between the garden area and the garden area. Obviously we cannot avoid unpredictable climatic factors, such as frost, drought and harmful hail. To avoid the damage of the latter, the plants must as far as possible be grown in pots or in greenhouses where the temperature is ideal for their growth. Plants grown outdoors like in the case of hedges, green lawns, trees, roses that undergo unexpected climatic and environmental factors, may be more prone to parasitic, bacterial and viral attacks, as the plant is be more vulnerable. Also the pollution can compromise the health of the plants especially in the case of the vegetables that I know can present with unsightly dark spots, a poor quality index.
DISEASES CAUSED BY CULTIVATION ERRORS
Cultivation errors can very often lead plants to diseases, especially if subjected to a rigid and scarce irrigation and fertilization or on the contrary abundant irrigation and fertilization. Furthermore, the plants have different needs depending on the species, some prefer light, others the shadow, even pruning and grafting errors can be harmful. Once the plant signals have been interpreted, any mistakes made can be corrected. The main symptoms are the yellowing of the leaves, caused by abundant irrigation and poor exposure to light, this problem can be solved by first exposing the plant to the sun, fertilizing it more frequently, and finally, reducing irrigation. The fading of the leaves is caused by soils with abundant limestone and a lack of fertilizers based on iron and magnesium. If the leaves are scalded and appear red, gray or brown, direct sun exposure must be reduced immediately. Finally, the crumpling leaves indicate radical damage due to too dry soil and due to too high a temperature, in this case it is possible to resort to repotting and to decrease the exposure to the sun.
Plant Diseases: TUMOR DISEASES OF PLANTS
Plants can be affected by tumors caused by viral and bacterial infections caused by parasites and fungi. The Agrobacterium Tumefavмciens causes the bacterial tumor that damages the roots and the woody parts of the plant. Plant cancer is capable of affecting both fruit plants and ornamental plants. To prevent this annoying disease, use phosphorus and potassium fertilizers. The fight against the responsible bacterium can also be practiced with the antagonist bacterium, namely the Agrotacterium Radiobacter K84.
