5 dangerous plant diseases that every gardener needs to know about

Not only people get sick, but also plants. Bacteria, viruses, fungi, and nematodes infect trees and shrubs, which can lead to serious illness and even death.

SSPDaily writes: "Even humans can become infected with such pathogens if they touch or eat a diseased plant. Here are 5 dangerous infections that you should protect your garden from in the first place."

Powdery mildew

Powdery mildew is a fungal infection. It's not fatal, but it will quickly make your outdoor plants look lethargic and sickly.

Its symptoms are white or gray powdery spots on the surface of the leaves and the stems.

If left untreated, the leaves will eventually turn yellow, curl, turn brown, and eventually die, while the fungus continues to spread.

Rust

Rust is one of the most common diseases of outdoor plants. Most often, roses, fuchsias, chrysanthemums, or pelargoniums become its victims. It is a very serious disease that spreads rapidly and can kill the plant.

Rust causes brown rings or spots on the leaves and often begins on their underside. Affected leaves fall off prematurely.

Black spotting

Black spot is a fungal disease caused by Pseudomonas bacteria. The fungus affects flowers, leaves, and fruits.

Symptoms: First, purple spots appear that turn black and cause the leaves to fall off. Spotting can be treated with an antifungal spray.

Keel

This disease usually affects root crops of bulbous crops – cauliflower, cabbage, Brussels sprouts, turnips, etc.

Keel is a fungal infection that causes twisting and swelling of the roots. It can also lead to the appearance of purple leaves, slowing their growth and wilting.

This fungus most often affects plants when the soil is warm and moist.

Spots on the leaves

Leaf spot is a common fungal infection that causes yellowing of the leaves and their premature fall.

These spots are brown or black with dark outer edges or concentric rings.

Keep the leaves dry and water the plants at their base to avoid infection. In addition, use antifungal agents to treat the garden.
