What should I do if succulents repeatedly appear scale insects?

Scale insects are the general name of insects of the family Homoptera, commonly known as scale insects, there are about 600 kinds of insects in China, and they are also one of the main pests that harm succulents. Scale insects usually parasitize on succulent stems and leaves, and live by sucking sap, which will cause succulent leaves to turn yellow and wilt in large numbers, and some smaller succulents will even die directly.

There are many reasons for the recurrence of scale insects in succulents, the first of which is poor ventilation in the maintenance environment. No matter what kind of succulent it is, it needs to be kept in a well-ventilated environment, otherwise it is not only easy to breed scale insects, but also easy to be infected with various germs, so the subject must put his succulent in a particularly well-ventilated place for maintenance. If it is an indoor environment, it is necessary to open the windows frequently for ventilation to let the air circulate as much as possible, which can not only reduce the probability of infection with the usual succulent scale insects, but also avoid repeated infection of the succulent scale insects.

Secondly, the scale insects are not cleaned up thoroughly. In addition to the activities on the succulent leaves and stems, the scale insects will also be active on the root system near the soil surface, and even lay eggs in the soil, more importantly, its reproduction rate is very fast, the reproduction of 1 scale insect can reach tens of thousands in 1 year, and the spring, summer and autumn are the active period of the scale insect (the indoor heating winter scale insect will also be very active), so it is difficult to completely remove the scale insect once it breaks out in a large area.

In addition, there may be insect sources in the vicinity. Succulents are raised in the open, if there are flowers and trees around, and there are scale insects on it, it is difficult to clean up the scale insects, because they can fly, and as long as the source of the insects is always there, you will always be troubled by scale insects. I have a friend who has powdery mildew on the trees around her succulents, which caused her succulents to be infected and have not been able to **, which is the same as the source of scale insects.

Repeated bugs are likely to cause problems with the soil. Dig up all the succulent soil and replace it with new soil. Spraying a thin mist of water will help the rhizomes to take root and sprout.

The body of the scale insect is encased in a carapace, and it is not effective to spray it directly with drugs. It is like a blood-sucking lice, sucking the sap of plants, thus causing great harm to flowers and trees, the damaged plants not only grow poorly, but also appear yellowing of leaves, early defoliation and other phenomena, serious will make the plant wither and die. The affected flowers include Milan, jasmine, camellia, and smile.

The methods of prevention and control are:

Mix liquor with water in a ratio of 1:2. When treating insects, water the surface layer of the potting soil thoroughly. Scale insects begin to move at room temperature 7 in spring. It can be poured once in April, and then every half a month or so, and it is effective for 4 consecutive times.

Use 50 ml of vinegar (rice vinegar), soak a small cotton ball in vinegar, and gently rub it on the stems and leaves of the affected flowers and trees with a wet cotton ball to wipe off and kill the scale insects. This method is convenient and safe, which can not only achieve the purpose of insect control, but also make the damaged leaves green and shiny again.

Gently and repeatedly rubbing the diseased plant with alcohol can remove the scale insects, and it can be removed very cleanly and thoroughly. If you wipe the orchid leaves with alcohol, not only can you get rid of the scale insects, but also the larvae that are not clear to the naked eye, and they are completely killed.

Mix the mother liquor with diesel, washing powder and water in the ratio of :6, at this time the mother liquor contains 60% oil, which is milk-like, dilute the 30% oil content with water, and carefully spray the scale insects on Milan, kumquat and cycads. After one week, most of the scale insects changed from fresh orange to shriveled state, indicating that this method has a good control effect on scale insects.

Let's go buy medicine, there are a lot of them, and my tree also has scale insects, just sprinkle some medicine.

Scale insects, which are pests with a hard, butterfly-like shell, are prone to disease caused by leaving plants in poorly ventilated places for long periods of time. If left unattended, the surface of the plant will be covered with this pest, which will weaken and wilt the plant. When there are many pests, a phosphorus mixture can be sprayed.

When there are a small number of pests and diseases, use a traditional toothbrush to get rid of them. Once an infestation occurs, it is difficult to completely remove it. Therefore, it is necessary to pay attention to check frequently, find insect pests in time, and eliminate them as soon as possible to avoid future problems.

Hope it helps you and hope your succulents get better soon

Scale insects have a strong reproductive ability and occur in multiple generations a year. The eggs hatch into nymphs, and after a short period of crawling, they live in a fixed place, that is, they form a shell. Scale insects have strong drug resistance, and it is difficult for general agents to enter the body, and it is difficult to prevent and control. Therefore, once it happens, it is not easy to clean up.

If you find that there are scale insects on individual branches or leaves, you can use a soft brush to gently brush them off, or combine pruning to cut off insect branches and leaves. It is required to be brushed, cut, and burned in a centralized manner, and do not litter.

It is still easy to kill with medication. Spray once every 7-10 days, 2-3 times in a row. It can be sprayed with 40% dimethoate 1000 times, or 50% malathion 1500 times, or 255 imithion 1000 times, or 50% dichlorvos 1000 times, or deltamethrin 3000 times.

Scale insects can be killed with potions. If you have less, you can solve it with tweezers or toothpicks, and if you have more, you can only use medicine. If it is a root scale insect, it is more troublesome, and it is not easy to clean up the root system.

Once the succulent scale insect is found, it must be isolated, otherwise there will be scale insects on all succulents within a month.
