Prevention Methods for Red Spider Mites on Balcony
A comprehensive explanation of the knowledge related to the prevention of red spider mites on the balcony is provided for you. The following is an introduction by the editor.
Recently, while answering questions for the flower friends in the family flowering training camp, I found that several flower friends' roses were infected with red spider mites, especially for roses grown on the balcony, which are prone to red spider mites. May is the season with a high incidence of red spider mites. So, how should we prevent and control red spider mites?
Prevention Methods for Red Spider Mites on Balcony
If you are growing roses on the balcony, it is recommended that you take the following three measures to prevent red spider mites.
1. -- Increase Ventilation by Opening Windows --
The reason why roses on the balcony often get infected with red spider mites is poor ventilation, resulting in a stuffy and hot microenvironment. Red spider mites prefer dry and hot environments. Therefore, when growing roses on the balcony, it is important to keep the windows open and place the pots at a height similar to the windows to enhance ventilation.
Meanwhile, it is necessary to promptly remove the old leaves at the base of the rose plant, prune the small blind branches inside the plant, and trim the weak branches, retaining only a few robust branches. Due to environmental limitations, try to maintain a relatively open plant structure for the rose.
2. -- Regularly Soak Pots --
Red spider mites often originate from the soil, so they initially climb from the potting soil to the leaves. Therefore, the best way to prevent and control red spider mites is to start from the source, which means killing the red spider mites and their eggs hidden in the soil. Since red spider mites are very afraid of water, the immersion pot method can be used to kill the red spider mites and their eggs in the soil.
The specific method is to immerse the rose pot in a bucket of water when the plant needs watering. Place the pot with the plant in the bucket, making sure the water level covers the surface of the soil, and let the entire potting soil soak in water for about an hour before taking it out and placing it on a shelf to drain excess water.
This method can not only kill the red spider mites in the soil but also other insects hidden in the soil.
3. -- Regularly Spray Laundry Detergent Solution --
In addition to immersing the pots, during dry seasons when red spider mites are highly prevalent, you should spray more water on the rose plants. Spraying water can increase air humidity and create a humid environment that red spider mites dislike.
However, simply spraying water has a relatively small impact on red spider mites. To prevent red spider mites, you can use a neutral laundry detergent to make a solution of 500-800 times, and spray once a week for prevention.
If you can do a good job of prevention, the probability of roses being infected with red spider mites can be greatly reduced. Once infected, it is necessary to treat it as soon as possible because red spider mites reproduce very quickly. Early detection and treatment can achieve twice the result with half the effort.
Control Methods for Red Spider Mites on the Balcony
To control red spider mites in the early stages, we need to recognize the early symptoms of rose infection. The early symptoms of red spider mites are often difficult to detect because they first infect the old leaves at the base of the rose.
Red spider mites gather on the back of the leaves, absorb nutrients from the leaves, and cause dense yellow and white spots on the leaves of the rose, as shown in the picture above. Therefore, it is important to pay attention to observation.
The best treatment method after the rose is infected with red spider mites is to use specialized miticides, such as daminozide, icaridin, abamectin, and hongsha. Since red spider mites reproduce quickly and resistance can develop with consecutive medication, it is best to use a "heavy-handed" approach to treat thoroughly.
Use a mixture of etoxazole and abamectin, prepare a mixed solution, and first spray it thoroughly on the rose branches and leaves. Then, place the rose pot in a basin and use the mixed solution for root irrigation. The combination of etoxazole and abamectin can effectively kill the red spider mites and their eggs.
After such operations, the problem of red spider mites can be basically solved. If you are concerned about any remaining mites, you can repeat the above operation in 3-5 days, or use a 300-fold neutral laundry detergent solution for regular spraying.
