Root rot is a disease that is hard to identify. It starts below the surface and spreads quickly on the whole plant. Meanwhile, identification of this disease is vital for your greenery. The faster you do it the more chances your plant has to survive. Although it is not easy to recover from root rot disease, it is still possible to save what is left.
Common Information on Disease
Root rot is not uncommon for household plants. It has a wide range of types but all of them are provoked either by fungal or bacterial infection. You can think of it as the condition that you may observe on the roots of the plant. The outdoor plants suffer from the disease less often than indoors. The leading cause of plant root rot is the lack of drainage systems in the soil.
No matter the cause, the pathogen prospers in the wet soil that stays moisturized for weeks and months. The plant starts to decay. Pathogens take all root rot, suffocating it. You may find the ways of the preventive procedure easier than the battle against a disease that is already there.
This plant disease does not give plants a chance. The roots are an important part of the plant, the source of water and nutrients. Without roots, the plant will not survive. When the root dies, you can say goodbye to the whole flower in the pot. Since plants require oxygen to consume food and receive energy from it. Without oxygen near the root, energy will not be transported to the plant’s cells. No matter which treatment you pick, the greenery will not be able to soak it.
Types of Root Rot
The classification of root rot is not simple since it contains too many diseases and species. Root rot can be considered the cause of fungal or bacterial infection spread. It means, you have not only different types of root rot, but even different pathogens behind them.
- Armillaria root rot is the fungal type of pathogen that is caused by the Armillaria genus. The symptoms include emaciated leaves, death of branches, and twigs. The common characteristics of all the hosts that were infected are that they are affected by the white root rot fungus;
- Clitocybe tabescens is the typical mushroom root rot. You may have seen it numerous times. Mushrooms turn black or dark brown before they die. It is similar to armillaria tabescens;
- Fusarium is a huge genus of fungi. It belongs to the hyphomycetes group. The most popular fungus sub-type that affects the rots is Fusarium solani. You can see this type on potatoes and crops that were planted in the soil where dry beans were previously grown Fusarium root rot can cost you the whole harvest;
- Ganoderma root rot. It is caused by Ganoderma fungi. Usually widespread among the mushrooms that grow on the trees;
- Phellinus weirii. This fungal pathogen causes the laminated root rot or so-called yellow ring rot. It is widely spread among trees in the US, including the Western white pine and Douglas fir.
Oomycetes or bacterial types:
- Pythium. The pythium root rot was also classified as fungi for a long time. Yet, it belongs to another genus called parasitic oomycetes. This is a standard disease of the crop that appear in damp condition. This disease can act together with pathogens like Rhizoctonia root rot as well as Phytophthora;
- Aphanomyces is an alfalfa disease. It is widely spread around the US Midwest. The pathogen quickly appears in the soils that are not drained properly. The gray color decay at the beginning is turned into black root rot;
- Phytophthora is caused by water molds or oomycetes. There are over 170 different species of the pathogen that are already found around the world;
- Phellinus noxius belongs to the Basidiomycetes class. This parasite causes the brown root rot in the plants. It is widely spread among trees and crops.
Apart from that, there may be root rot nematodes that attack your flowers. They belong to the Meloidogyne genus and exist in the soil. They infect the plant’s roots producing the larvae that feed there. Larvae drain the root from the inside.
Symptoms of Disease
It is easy to see the signs of the problem if you know what you are looking for. For starters, the root rot leaves are usually dark or covered in numerous black and brown spots. However, you don’t have to wait till you notice the problems with the leaves. The faster you take everything under control, the more effective the cure will be. Pay attention to the following symptoms:
- your plant declines without any reason;
- the leaves are getting pale and decrease in size;
- the growth is stopped;
- leaves can turn brown, yellow, and wilted;
- branches began to fall off;
- canopy is thinning;
- sometimes the pathogen spreads from roots to stems and leaves;
- the ground of the plant is constantly wet and sometimes even covered with a white mold;
- the water is not soaked as fast as it used to;
- you will see that the plant is wilting.
If you can see the rot without hurting the plant, do it. You can dig the ground slightly. Check out whether the root is not mushy and black. You can even smell the decay if the roots are already affected. If you can touch like in the case of root rot hydroponics, check whether they hold firmly or fall apart from a gentle touch.
