Cause Of Root Rot: Root Rot Remedy For Garden Plants, Trees, And Shrubs

Root rot is one of the most common diseases afflicting many types of plants and trees. Although it may not seem like it at first glance, root rot can affect any type of plant or tree.

However, its effects are usually worse on trees than other kinds of plants because they have less defenses against disease and pests.

The symptoms of root rot vary depending upon the kind of plant affected. Some varieties are susceptible to a single type of infection while others may show multiple forms.

Symptoms include yellowing leaves and branches, wilted foliage, brown spots (pitting) on the woody parts of the plant, and eventually death.

Symptoms of Plant Disease: Causes & Prevention

Plants are constantly exposed to environmental factors such as temperature, light intensity, soil moisture levels, insect activity and so forth. These factors all play a role in determining which species will survive and thrive under different conditions.

One factor that often goes overlooked is the presence of pathogens within the environment. Many times these organisms cause damage without causing much harm to the host plant itself. However, in other instances infection and disease can cause permanent damage or even death.

When a group of organisms causes damage or disease to a plant, we call it an infestation. The different types of organisms that can cause an infestation are commonly referred to as pathogens.

There are several different types of pathogens that can affect a plant including bacteria, viruses, fungi, insects and more. Some of the most dangerous pathogens are the fungi.

The word fungal refers to a large group of organisms that do not fit into the other categories. This includes organisms such as molds, mildews and mushrooms.

Of these fungi are actually only a small part of the whole group. Despite their different appearances and habits, they do have some similarities. All fungi are made up of tiny microscopic cells that are typically too small to be seen without the aid of a microscope. Each of these cells contains a central core called a nucleus that controls the functioning of the organism.

Plant disease caused by fungi often goes unnoticed until it is too late to save the plant. One of the main reasons for this is that many fungal diseases first appear as spots on the leaves or skin of the plant.

These spots can sometimes be seen with the naked eye, but they may also be so small that they can only be seen with a magnifying glass or microscope.

Claviceps purpurea is a type of fungus that attacks the stems and head of the plant (where the seeds are formed). It usually infects wild growing plants such as wild oats, wild rye and other similar types of grasses.

However, it can also infect other types of grasses such as Wheat, Barley, and other cereal grains used for food. It also affects various types of wild and cultivated grasses in Africa and South America.

The infected grain often grows normally until it reaches the flowering stage. At this point the fungus begins to grow on the stem and head of the plant.

It typically grows under the husk or outside covering of the grain. The infected grain appears as normal until it is harvested and eventually grows into maturity. By this time, the fungus has caused substantial damage to the head and grains. The fungus itself produces a toxin that affects both the reproductive organs and developing kernels of the plant.
