1. Detergent containing detergent water
Many people are reluctant to use drugs to kill insects when they grow flowers at home, for fear of polluting the environment. If it is a plant hopper or a budding insect, it is worth trying to kill the insect with soap powder. Dilute it into soap powder according to the ratio of 1: 200 and spray it on the branches. Soap powder contains sodium alkylbenzene sulfonate, which is similar to chemical fertilizer and can be used as insecticide.
However, soap powder is mostly acidic, and long-term use is unfavorable to the growth and development of flowers and plants. On the second day after spraying the branches, wash the potted flowers with warm water first, and don't let the soap powder liquid remain on them.
2. Onion water
The onions we usually cook also have a good insecticidal effect, and the weather is still hot and harmless. Spraying potted flowers with onion water for a long time can also play a bacteriostatic role and make potted flowers grow stronger. Insecticide made of onion is safer to use. When using onion to kill insects, it is necessary to chop the onion, add water according to the ratio of 1:50, leave it for one day, and then spray the fermentation broth on the branches with pests and diseases for two consecutive times.
3. Chili oil
Many flower lovers will use Chili oil to make pesticides after insects occur in potted flowers. However, it is best to choose hot peppers. If it's spicy, it shouldn't have any effect. It's best to use that kind of dried pepper.
Chopping pepper and soaking it in clear water for 24 hours, soaking the sweetness in pepper, filtering out the sediment, and spraying pepper oil on the branches of insects can completely kill insects several times.
Add water to cool oil
The cool oil commonly used at home in summer has a refreshing effect. Putting a little on your body can not only repel mosquitoes, but also be effective for potted plants with all kinds of bugs. You can also prevent potted flowers from getting insects by spraying water.
If there are pests such as rice planthoppers, budding insects and blackfly in potted plants, you can use a watering can to hold water, drop 8 ~ 10 drops of essential balm on the indoor floor, and then spray it on the branches of potted plants with insects, and the pests and diseases can be completely eliminated twice.
Step 5 soak tobacco in water
In addition to the above three methods, there is another method that people will use more, that is, using tobacco pipe silk to make tea to kill insects. Tobacco pipe silk contains several harmful substances such as tobacco tar, which can also play a particularly good insecticidal role.
For example, if there are bugs in flowerpots or on the branches of potted flowers, you can make tea with pipe tobacco, and the thicker it is, the better. Finally, filter out the sediment and spray insects with tobacco water, which can also effectively eliminate all kinds of bugs.
During the period of high incidence of potted plant diseases and insect pests, many flower friends are also very prosperous about this matter. Interviewing at home, these pest control methods are nontoxic and harmless, and the effect is obvious.
