What to do about Monstera rust

1. Causes

The main cause of the disease is that the plants are infected by bacteria. The infected fungi are extremely tenacious and can successfully survive the cold winter in the plant's body. When the weather warms up in the spring of the following year, it begins to recover and harm the growth of the plants. At the beginning, it started from the middle and gradually changed from gray-brown to gray-white, gradually sinking, and there was also a raised yellow-brown line on its edge. Yellow, rust-like powder also grows on the back of the leaves, and this is the source of the bacteria.

2. What to do

1. This often happens because too much water is poured, which makes the plant's roots very fragile and grows poorly. Therefore, you need to cut off the diseased area first, and then burn the cut leaves. If the planting is dense, it is necessary to clear it to avoid it being planted too densely.

2. In the spring when the disease is more common, it is necessary to spray it with some Bordeaux mixture for protection. If the disease has already occurred, you can also spray it with a solution of oxycarboxin mixed with water. Alternatively, you can use a mixture of bactericidal drugs such as thiophanate-methyl and thiophanate-methyl to spray the entire plant, which can be very effective.
