Flowers & Gardening 0 views
This plant is easily attacked by various insects, so you need to guard against them strictly. Once you spot them, deal with them right away. For this kind of insect, there are mainly two situations to discuss. First, if the numbers are not very large, you can crush them with your hands or wipe them off with a cloth. However, in most cases their numbers are still quite large. At that point, there are two options. One is a physical control method: light a mosquito coil. The other is spraying a pesticide, such as trichlorfon.

1. Pest Introduction

You may never have heard this name, but you are probably more familiar with "aphid." It can threaten leaves, stems, flowers and various other parts. In severe cases, it can cause the plant to die. In addition, the substances it secretes can lead to other diseases.

2. Dealing With a Small Number

Sometimes the pest infestation is discovered early enough that the numbers are not too large. In that case, you do not need to go to the trouble of spraying pesticide. You can simply crush them all with your hands, wipe them off with a cloth, or spray water from a spray bottle to wash them off. These are all fairly simple methods,

and easy to carry out. However, in most cases the numbers are very large, because this insect has a strong reproductive capacity. So if you still use these methods, it will take a great deal of effort and is not worth it. Let us then look at the next situation.

3. Dealing With a Large Number

(1) Physical method: Use a plastic bag large enough to cover the plant together with its pot, gently covering it from top to bottom. Be careful to avoid touching the plant as much as possible. Otherwise, these insects will easily move around. After covering it, light a mosquito coil, place it inside, and seal the opening. The interior will then fill with smoke. After about a few minutes, these insects can be eliminated. And because the time is relatively short, it will not harm the plant.

(2) Chemical method: This means spraying some chemicals. The more commonly used one is a 90 percent trichlorfon solution at 800 to 1000 times dilution.
