Why You Need a Good Natural Fungicide For Succulents

From powdery mildew to sooty mold and more, you can find certain fungal bodies attacking your plants as the root and crown rots when they develop fungal infections.

Here are a few more common fungal attacks you may face and why you need more than your homemade fungicide.

Black Sooty Mold

Black sooty mold, also known as Black Mold, is a fungal infection that belongs to the least damaging fungi for succulents.

The sweet substance called honeydew the insects exude is thought to be the source the sooty mold feeds on. Mealybugs, aphids, whiteflies, and scale are the insects that produce this delectable material.

The honeydew sweet substance feeds the mushrooms and aids their reproduction in Black mold. Although the least damaging fungi you can face, it can prevent succulents from carrying out photosynthesis on the sooty mold-affected leaves thanks to the sweet substance called honeydew.

Grey Mold

This type of fungal diseases is known as grey mold (Botrytis cinerea) and is easy to spot as gray mold appears on the surface of succulent leaves and flowers.

The gray mold fungal infections generate grayish-brown spore masses. This form of illness thrives in the early spring or summer when the temperature is chilly and rainy.

A Grey mold infection typically begins in old, damaged, or dying plant tissues, and the Grey mold infection spreads through susceptible plants.

Leaf Spots

Succulents are unaffected by these fungi since they have a high tolerance. However, despite being among the least damaging fungi compared to other fungal diseases, it can alter the appearance of succulents.

Shallow tan lesions or permanent stippling or leaf and stem spots appear on the affected succulent.

It won’t do much harm, but if a succulent becomes infected with this type of fungus, it can spread the infection to other plants and thus potentially affecting all of them.

Fusarium Wilt

This type of fungal infection is caused by the pathogen Fusarium oxysporum, making a succulent incapable of absorbing water.

As a result, Fusarium wilt can cause a succulent to face heavy stress, wilting, yellowing, and probable death. This fungus enters the roots and travels through the vascular tissues.

As you see plants under heavy stress, wilting, yellowing, and slowly dying, it is because the vascular tissues become clogged. The effect of this is the plant tissues can no longer absorb water. As a result, the succulents with Fusarium Wilt develop brown streaks you can only see once you cut the leaf of affected plants.

Anthracnose

Genus Colletotrichum is the type of fungus that causes this sickness. A moist tan-colored rot with red-orange, pink pustules on the surface of the afflicted succulent is possible.

Unlike other fungi that cause less harm, this can affect a wide range of succulent plants. On leaves and crowns, the spots typically begin and spread swiftly. The fungus spreads by using contaminated pots and soil to do so.

The best remedy to stop this incurable soil-borne fungus is to avoid reusing garden soil and thoroughly sterilize all your tools before using them. It’s also a good idea to cut out the affected area to prevent infection from spreading.

Root and Crown Rots

The Genus Phytophthora is responsible for this type of illness. However, comparing the symptoms of this fungal infection to those of other fungal illnesses is quite tricky. This is because this fungus has no specific symptoms, thus hard to tell the succulent is infected.

The illness originates in the soil and spreads upward. You can avoid it by giving succulents plenty of water and planting them in well-draining soils.

Check the mixing directions.

Fungicides aren’t all created equal. Therefore, there will be changes in the recommendations for combining and applying it to the plants. (Learn How To Plant Succulents In Glass Containers)
