More than 7 thousands of fungi species are responsible for this disease. A tell-tale sign of this problem is pustules of yellow, orange, and brown powdery pustules that can be found on leaves, fruits, and shoots. Even visually, the rust on the plants is kind of similar to the regular one. Rust rarely kills the plant but reduces its growth and affects its look. Mild and moist conditions are the most favorable for this fungal disease. That’s why rust disease spreads after watering because wet surfaces are generally suitable for fungi. Air is another way of spreading this disease because it is transferred by spores it has.
Rust
Signs of damage
- General weakening. As with any disease, this one influences a plant’s vigor.
- Yellowish spots on the leaves. This sign can help to identify the problem at the beginning.
- Pustules of yellow or red colors. They remind of blisters, and their appearance is the most important sign that the plant is affected.
- Deformation of the leaves. Obviously, if the plant is loosened, it affects its look; deformed leaves prove it.
How to prevent
Be careful with watering; as we have mentioned, fungi thrive in moisture. It’s better not to practice overhead watering so the leaves won’t be wet. Good air circulation is more helpful than you think because it can also prevent this disease. That’s why it’s better to provide plants with more space.
Heal
Once the plant is affected, destroy the diseased leaves so the illness won’t spread further. After this, you need to sanitize your instruments. Mainly when it comes to diseases caused by the fungus, fungicides are the first thing that might occur first, and for a reason. Sulfur or copper-based ones are very helpful in this case. Neem oil also seems to be the most popular remedy that is also effective with rust.
