How to deal with small flies on green radish, why are the leaves turning yellow

1. Treatment methods

1. Insecticide: After discovering that green radish is effective in killing flying insects, the easiest way is to buy insecticide. When using, you need to dilute it in advance and then spray it evenly on the potted plants.

2. Homemade insecticide: This method uses tobacco water, sugar water or garlic juice to repel insects, and the preparation method is also very simple. Put the tobacco in water for 8 hours, filter it and spray it on the places where there are insects. Crush the garlic and put it in water. It will be ready to use after about a day. Spray it on areas where there are pests.

3. Disinfect the soil: If you want to completely remove small flying insects, you must disinfect the soil. You can take out the plants and place the soil under the sun to dry. Alternatively, spraying with carbendazim solution can also achieve a disinfecting effect.

2. Causes of yellowing

1. High temperature: If the temperature is too high during maintenance, the climate will become very stuffy. If the plant stays in such an environment for a long time, the leaves will turn yellow. You should pay attention to cooling down and open the windows more often.

2. Too much water: If the amount of watering is not well controlled, the accumulated water in the soil will damage the root system of the plant, and the leaves will easily turn yellow after the roots rot. If the yellowing is mild, just drain the water in time and ventilate the soil. If the yellowing leaves are serious, you need to remove the plant from the pot, cut off the rotten roots, and replant it.
