What are the different types of crop disease?
Every year, agricultural manufacturers lose a huge number of crops on different crops. To understand how and why certain diseases will affect certain crops, pathologists have categorized all diseases into two general groups, infectious and non -infectious. Once they are segmented in one of the categories, the disease is described by the characteristics of the offensive cause of pathogens or environmental, such as fungus, bacterial, extreme temperatures or lack of soil. Finally, gardeners also classify diseases according to the affected crop, such as leaves, root diseases and others. There are a number of different types of crop disease, but all diseases are basically in the category of infectious and non -infectious for further classification.
non -infectious or abiotic diseases are diseases that are caused by unfavorable circumstances of the environment and that do not apply living organisms. In general, non -infectious diseases tend to weaken the plant, which makes the plant prone toMore serious infectious diseases. Examples of non -infectious diseases include extreme temperatures, excessive or lack of water, insects, poor soil nutrition and toxic chemicals. These factors can weaken the whole plant or a certain part of the plant, which makes the plant susceptible to infectious stalk diseases, seed diseases, diseases under and more.
Infectious or biotic diseases form most of the diversity of crop disease. They are caused by living organisms that infect the crop. Mushrooms such as sadness, rust, forms and molds are the most common cause of crop disease. Most mushrooms require very humid conditions under which they are successful and reproduced. Some mushrooms develop pustules on crops, while others produce a colony of powder, faded soot.
bacteria and viruses that are other infectious hosts are a small organmimemism that infiltrate the plant organs and reproduce. Some BakTerie does not harm crops, but others can produce toxins or attack plant cells for food. Viruses are usually spread by insects when the insect chews the protective outer layer of the plant and infiltrates internal cells. Bacterial fungi and wilts often sea crops of wheat and barley, as well as vegetables such as cucumbers and beans. Crop diseases caused by viruses can cause considerable damage, such as the mosaic virus and potato virus, before they can eradicate the whole crop very quickly.
Nematodes and Protozoa are also classified as an infectious disease. These small worms similar to organisms are located in the soil and await the opportunity to attack the crop with weakened non -infectious causes. They can carry viruses and cause further damage to crops and complicating the treatment of the disease. Examples of these biotic diseases include the nematodes of potato cysts, pine and soy cyst of the Nematoda. As the names were detected, these diseases of the crops attack sensitive root or vascular crops and crops andThey cause cysts that cover the growth of plants and sharply reduce crop yields.
Restriction or treatment of crop disease is a large enterprise. Scientists and farmers have developed countless fungicides, insecticides, pesticides and antibacterial solutions to control crop disease. While the progress has occurred, pathogens showed tough susceptibility to adapt to the repellent substances. As the agricultural industry learns more about different types and causes of crop disease, it is better equipped to treat and prevent many diseases that suffer from crops in the world.
