The Common Types of Plant Diseases to Watch for (Part 2)

Continuing from the previous post, in this one we are going to learn about other common types of plant diseases to help you identify one when you see one. As you see, there is a wide range of plant diseases and being able to recognize them is the first step to doing what you have to do with your plants.

Here some more plant diseases for you to observe as well.

  1. Black Spot

Black Spot is a disease that commonly strikes roses. Black spot appears on the leaves, up to a half-inch across, forming yellow margins. If left unchecked, it can cause a rose bush to totally defoliate. After your rose bush is infected by black spot fungus, the markings will stay there until the marked leaves fall off. Black spot is usually wind-borne. It occurs during moist and humid conditions.

  1. Leaf curl and blister

These fungal diseases cause curled leaves on many trees. There are many different types of these diseases. Peach leaf curl can occur on almonds and peaches. You may see that new leaves are pale and the midrib doesn’t grow along with the leaves, which causes them to curl and pucker as they grow. This results to damage in the fruits and worse, it could kill the tree.

Leaf blister can kill its tree. These blisters appear as yellow bumps on the upper surface of the leaves and gray depressions on the lower surface.

  1. Club root

Club root are likely to occur in flowers and vegetables especially in the cabbage family. Plants infected by this fungus will typically wither during the day and become revived again at night. The older yellow leaves will drop off eventually. The roots are often swollen or distorted. This disease can cause plants to die and reduce yields.

  1. Wilts

Your plants wilt or wither when they don’t get enough water. Some fungi or bacteria cause permanent wilting, sometimes turning them into yellow, that is eventually followed by the death of the plant. Wilts are any number of diseases that distresses the vascular system of plants.

Control measures will highly depend on the proper identification of plant diseases. Make sure to isolate the plant of the disease-causing agent to avoid further damage.

The Common Types of Plant Diseases to Watch for

Plants can get diseases, too. If you are regularly observing your plants and you notice that they are beginning to look odd, chances are that these plants of yours are already infected by plant diseases.

Now, you have to act fast because you know that plant diseases could spread to all the other neighboring plants. But sadly, you don’t know what to do. That could be the worst scenario, right?

Today, we are going to learn all about the common plant diseases and what to do when you encounter them. Read on and discover a lot about these pesky diseases.

What are plant diseases?

Plant diseases are typically caused by fungi. Some other causes include bacterial and viral infections. These are some of the most common plant diseases.

  1. Cankers

Cankers are characterized by dead areas on a plant’s stem that turn to be discolored. They usually form on woody stems, and can be sunken areas, cracks or raised areas of abnormal or dead tissue. They may ooze or girdle trunks or shoots, which can cause everything to die.

Types of cankers are cytospora and nectria cankers.

  1. Blights

There are a few types of blight to watch for. All of which are easily identifiable as they all cause the sudden death of all plant tissues such as the flowers, stems and leaves.

  • Fire blight

Fire blight is a bacterial disease that affects fruit trees, roses, and other small fruits. Shoots will look blackened once they get affected. You may notice lesions on the branches and limbs that secretes an amberish-brown liquid on very warm days.

  • Early blight

Fungal blight can infect plants, vegetables, shade trees and fruit trees, but when it strikes tomatoes, peppers or potatoes, it’s called as early blight. Symptoms include brown to black colored spots on leaves which develop concentric rings. When heavily blighted, the leaves dry up and die as the spots grow together. The symptoms are noticeable on the lower leaves first.

  • Late blight

Late blight can infect certain flowers causing dieback of shoots and stem cankers. It can also common in tomatoes, potatoes, and peppers. The early symptoms include water-soaked spots on lower leaves, which widen gradually and are mirrored beneath the leaf with a white soft growth. You may see dark-colored blotches penetrate the flesh on potatoes appearing as sunken lesions. The affected plant is about to rot and die during wet season.

  1. Rusts

This is not the ones you see on metal. Rusts are another type of fungal disease. Two different plant species may be needed by these to use as hosts in order to complete their life cycle. The usual symptom is a light brown to rust-hued coating, that often appears first on small branches.

These are just a few of the common kinds of plant diseases. Discover more about the others in the part 2 following this post.

The Dangers of Chemical Fertilizer

Since the 1930’s, farmers have been using chemical fertilizers to increase crop production. Chemical fertilizers may have been helping the farmers to increase the quality yields but they also cause some serious harmful effects.

We tend to overlook these harmful effects as long as we benefit from having as much organic products as we need.

But at some point, we really need to understand and address this issue.

What are fertilizers?

Fertilizers are any substance used to increase nutrients to the soil to help in the plant growth. Fertilizers are not applied for the soil’s health. They are just made for the sole purpose of increasing the growth of plants.

What are the dangers of using chemical fertilizers?

These harmful effects of chemical fertilizers seem to have been disregarded for so long.

  1. Groundwater contamination

The most critical issue in using chemical fertilizers is groundwater contamination. Groundwater is being utilized for drinking water. Nitrogen fertilizers break down into nitrates and travel easily through the soil. Studies suggest that nitrogen intake can pose dangerous risks to our health.

  1. Waterway pollution

Chemical run-off has excess fertilizers causing adverse effects on waterways. It creates an imbalance between oxygen and nutrients in the waters. Oxygen depletion causes fishes to die.

  1. Air pollution

The increase in nitrogen in the fertilization of crops may cause greenhouse gases like nitrous oxide and CO2 into the atmosphere.

  1. Mineral depletion and acidification on soil

The continuous use of chemical fertilizers depletes the natural nutrients in the soil. Crops from these soils would have less vitamins and minerals in result. Also, overusing chemical fertilizers can also lead to soil acidification.

  1. Chemical Burn on Plants

It’s ironic how these chemical fertilizers negatively affect the plants. Over-application of chemical fertilizer to plants can damage the plants and decrease the crop yield. The condition is known as chemical leaf scorch. It initially causes the leaves to wilt and eventually kills the plant.

All You Need to Know about Biofungicide

Plants can be highly vulnerable to wide range of pathogens. Without proper treatment, other plants nearby can also get infected.  Once creative method for controlling disease among greenhouse and other commercial crops is by using biofungicide.

What is a biofungicide and how does it work?

What is a Biofungicide?

A biofungicide is made up of beneficial fungi and bacteria that colonize and attack plant pathogens. By controlling these pathogens, it eliminates the diseases they cause. This is an environmentally friendly alternative to chemical fungicides. The microorganisms used in bio fungicides are naturally found in soil.

Moreover, using biofungicides in plants is an effective way to protect your plants from pathogens that are becoming resistant to chemical fungicides.

How does it work?

There are few ways in which biofungicides control other microorganisms.

  1. Through antibiosis.

Biofungicides are capable in producing chemicals similar to an antibiotic. These chemicals are destructive for the pathogens.

  1. Through direct competition

Biofungicides grow a defensive obstruction around the roots of the plant, giving it an effective shield from harmful attacking fungi

  1. Through predation of the biofungicide

These biofungicides assail and feed on the harmful pathogen. This is quite useful as it makes the elimination of pathogens easier.

  1. Through building up the immune system of the plant

Using biofungicides stimulates the plant’s own immune defense mechanisms, for it to successfully defend itself from pathogens.

How do you know if it’s time to use a biofungicide?

Biofungicides can’t cure damaged plants. It can only protect a plant from harmful pathogens. Application of biofungicides must be made prior the development of disease.

Early application protects the roots against attacking fungi and boosts development of root hairs.

Biofungicides are used as first line of defense to pathogens. You have to make sure that the biofungicide you use according to the instructions provided by its manufacturer for better results.
