I believe that many northern flower friends will be equipped with a greenhouse at home, which is used for succulent people or other flowers to spend the winter. But now many flower friends are not good at the management of greenhouse culture, and there are few articles about greenhouse culture on the Internet. So, this paper is compiled from a flower friend who has many years of experience in greenhouse culture, and his views on the prevention and control of multi meat scale insects in greenhouse culture are very valuable for novice flower friends.
How do succulent plants control scale insects? How do succulent plants control scale insects? First of all, we need to know that the insects in the shed are difficult to completely remove, or even impossible to remove. If we do not prevent and control them, there will be a major outbreak in a few months (for the eggs, they will not die until they are sprayed with medicine directly, and they will not hatch all at once), so we just bought them Don't put them together with the plants you already have. They should be isolated for at least one to half a year, especially in spring and autumn. They are fleshy and grow fast, and insects grow fast, and autumn is more suitable for their reproduction.
I feel that everyone likes to use huahushen. This medicine can kill most pests as well as the larvae of scale insects, but it can't protect the adults and eggs with waxy shells, and it's not cheap. I don't recommend it. I don't use it now.
In recent years, I have used several kinds of medicine. Generally, I seldom use one medicine alone. There are more cases of mixed use of the two medicines. I spray them twice in spring and twice in autumn. Other time depends on the situation, mainly toxic chlorpyrifos, abamectin EC, Omethoate, buprofezin, fenpropathrin, and chlorpromfos. There is no doubt that methidathion is the best medicine for killing scale insects. It can be absorbed by plants. Scale insects will be poisoned and die after sucking plant juice. In addition to killing scale insects, it can also kill many other insects. The control effect is very good. Omethoate is more suitable for use in early spring and late autumn when the temperature is low, and the effect of high temperature is not good. It's all one medicine against many insects. It's very suitable for greenhouses. Because these are basically organophosphorus insecticides, more toxic, it is not very suitable for home use, non closed balcony or roof can be.
How to control scale insects with succulent plants
What kind of medicine should be used for fleshy sowing?
Carbendazim is just for prevention. In case of mold outbreak, soil must be removed and carbendazim dry powder must be sprinkled. Do not spray carbendazim in water. In case of failure to kill this kind of fungus, it will spread. Finally, the whole basin is covered with mildew. It is not recommended to use it in the greenhouse.
Potassium permanganate can be used, but it is not used to soak soil, but to soak seeds. Cactus and other relatively large seeds are soaked for half an hour before sowing, and then soaked with water to reduce the concentration of the drug before sowing, which can prevent the seeds from getting moldy. Large seeds such as Queen aloe and tortoise shell beetle can also be treated in this way. These seeds germinate for a long time and are easy to get moldy (recently I saw that someone in the forum broke the seed coat of Queen aloe to help germinate, which is very good. You can search related posts).
The fungicide used in greenhouse sowing is usually hymexazol, and streptomycin is also used in seedling stage. Tuchongdan indicates that it has never been used before. Carbofuran is used in greenhouse. Tobuzin can be used for cutting to improve the survival rate. It can be used to solve all kinds of leaf spot SCAB (the killer of Sclerotinia sclerotiorum).
The medicine shed mentioned above has low price and good effect. The only disadvantage may be that it is more toxic. Pay attention to wearing a mask when using it.
I think the most important thing is to focus on prevention, supplemented by killing. It can be used once a year when the temperature is above 10 ℃ from March to April. It can also be used when the temperature drops below 35 ℃ just after the high temperature in August to September. The spraying time is sunny, and the effect is the best when the sun just sets, which is most conducive to plant absorption. The growth period is about once a month. If you miss the injection time and don't prevent the outbreak of insects, use it again every other week.
