Can I use soapy water to treat black spot disease of green radish?

1. Can it be used?

If the green radish has black spot disease, it is best not to use soapy water, as it has no actual therapeutic effect on this disease. The main reason for the black spot disease is the humid growing environment, so it is even more inappropriate to spray water on it. Moreover, fertilizer water is alkaline, and plants prefer acidic loam. If too much is applied, the potting soil will become alkaline, causing problems for plant growth, and may cause plant stunting, which will weaken over time.

2. How to treat

1. Cut off the black leaves: When you find black leaves on the plant, cut them off immediately because they contain mold. If they continue to grow on them, they may infect other branches and leaves, causing damage.

2. Maintain temperature: Another reason for this situation is low temperature. The temperature needs to be maintained within an appropriate range. Around 20 degrees is most suitable. Be careful not to suffer from frost damage in winter and move it indoors for maintenance as soon as possible.

3. Spraying medicine: If the situation is very serious, you can go to the pharmacy to buy some special treatment medicines, dilute them with water and spray them on the plants. In addition to the roots, you should also spray the leaves.
