There are a lot of tiny red spiders on the jasmine raised at home, how to treat it

1. Ventilation I think this is the most important point, the key to your flowers is poor ventilation, which leads to red spiders.

2. Take a closer look at the ** of the red spider, whether it is brought by the newly bought flowers, or the flowers at home are born because of poor ventilation. Be careful after finding out the cause!

3. Prevention and control of flower spider mites.

Spider mites are a common disease in the flower cultivation process.

The bugs are small, less than 1 mm, round or oval, orange or reddish-brown. Because of its small size and difficulty in being found, once it is found to be harmful, the damage to flowers is often more serious. This insect pest method is to pierce the mouthparts into the flower leaves and suck the sap, so that the chlorophyll of the flowers is destroyed, the leaves appear gray and yellow spots or patches, and the leaves become yellow, or even fall off.

Spider spiders are very reproductive, and can reproduce one generation in about 5 days at the earliest. This insect prefers high temperature and arid environment, therefore, in high temperature and arid climate conditions, it reproduces rapidly and causes serious damage. Insects mostly swarm on the back of flower leaves and spin silk nets to cause damage.

In addition to crawling on their own, the spread of spider mites is also an important transmission route by wind, rain and operation.

To prevent spider mites, you should pay attention to the flowers, and when you find that the color of the flower leaves is abnormal, you should carefully check the back of the leaves. When individual leaves are damaged, insect leaves can be removed; When more leaves are damaged, spraying should be carried out as soon as possible. Commonly used pesticides include mite, dicofol, dimethoate, flower insect net, rapid kill and so on.

A flower sprayer can be prepared for raising flowers at home, and 4 drops of carite or rapid killing or flower insect net 4 drops (equivalent to 2000 times the solution) in 400 ml of water, or 8 drops of dicofol or dimethoate (equivalent to 1000 times the solution), shake well after adding the medicine, and then spray. The spraying requirements are uniform and thoughtful, especially the back of the leaf should be sprayed. When spraying, it is best to move potted flowers outdoors.

If spraying indoors, do not approach food and utensils. After each use, pour out the excess liquid and wash the sprayer with clean water.

Pepper water treatment flower spider method.

This method is also more commonly used, and the occurrence of red spider disease in flowers can be sprayed with water from boiling peppers. The effect is also very good, the raw materials are easy to take, and they are generally available at home.

But it should be noted that all these methods should be used in small amounts, not too much, step by step, spray red spiders a few more times to remove them naturally, and it is not good for flowers to be too hasty!

Tobacco leaves can also be soaked in water, master the amount, and take the spraying method to deal with it!

Hello, to use medicine to kill insects, the following is the management method, you can refer to management.

1. Temperature. Because jasmine is native to India, it prefers high temperatures, so it is important to take measures to prevent frostbite in winter.

<> jasmine. 2. Pruning.

Jasmine is actually a liana, so when cultivating, there will be a problem that a single branch is too long, which is very abrupt on the plant and affects the appearance, so we have to prune the jasmine to maintain a plump plant shape. This kind of branch is often more vigorous, when pruning, do not simply cut it flush with other branches, but slightly concave and shorter than other branches. In this way, the branches that grow after the plant germinates again also have some room to grow.

Pruned shoots can be taken for cuttings. In an environment where the temperature is above 20 degrees Celsius, the section close to the cut of the branch is inserted into the soil to provide suitable climatic conditions and it will take root and grow into a new plant.

3. Moisture. Jasmine prefers a humid environment, all of which have high water requirements and cannot be kept in a relatively dry environment, and if the potting soil is too dry, the root system will be damaged.

<> jasmine. Fourth, light.

Jasmine likes strong light, and there is a folk saying that "jasmine can't die", as long as it is exposed to the sun during the growth period, it will grow well. If you breed in the shade for a long time, there will be many weak branches, yellowing, falling off, scorched edges, and dry edges.

5. Fertilization. Jasmine blooms a lot, so it consumes a lot of nutrients, and it takes about half a month to add a thin compost during the growth of jasmine. The type of fertilizer can choose the commonly used organic fertilizer, such as:

Soybean cake water, compost, etc. can be used, and slow-release fertilizers and compound fertilizers on the market can also be used. When fertilizing, follow the principle of "thin fertilizer and diligent application", and the one-time amount should not be too large, especially in winter and high temperature season, to avoid fertilization, and then fertilize in the growing period is better. It is recommended to use foliar fertilizer in combination to increase the flowering period and make the leaves and flowers more vivid.

6. Pests and diseases.

Sometimes you will encounter spider mites, and there will be irregular small yellow dots on the page, the yellow dots are relatively small, similar to the eye of a needle, and white flocculent matter can be found when you turn over the leaves, which is the residue of the red spider spider's drawing and peeling.

Solution: We can rinse the back of the leaves with water and spray the whole plant with acaricide if it is severe to kill the spider mites.

Jasmine is most afraid of red spiders, so spray it with your hand to easily solve the yellowing of the leaves.
