I bought a pot of dripping Guanyin, but I found that there were black worms on it, what should I do?

If it's just a small amount of bugs, wipe it off with a cotton swab. If the number is relatively large, you can use mosquito control medicine at home, such as "pest killer", to spray the whole plant once a week.

If this happens, you can look it up online and then prescribe the right medicine.

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 plants with sprinkler sperm can get rid of scale insects, and they can be removed very cleanly and thoroughly. If you wipe the orchid disease leaves with sprinkler semen, not only can the scale insects be removed, but also the larvae that are not clear to the naked eye, they are also completely killed, and the second year is rarely found to have scale insects as a pest, this method is simple, safe, and the effect is good.

Use diesel, washing powder, water according to the ratio of :6 to adjust the mother liquor, at this time the mother liquor contains 60%, milk-like, diluted with water 30% of the oil solution, the Milan, kumquat, cycad on the scale insects carefully sprayed. 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.

Poisonous plants can also attract insects.

There is a system on the leaves of the dripping water revert to Guanyin.

There are small red white insects on the top of the layer, which is a pest du red spider.

Red spider, also known as cotton red spider, commonly known as DAO spider, big dragon, sand dragon, etc., scientific name leaf mite, the species of our country are mainly cinnabar leaf mites, belonging to arachnids, ticks, leaf mites. It is widely distributed and has a miscellaneous diet, which can harm more than 110 kinds of plants.

1) This insect is very small, less than 1 mm, round or oval, orange or reddish-brown, because of the small size is not easy to find, once it is found to be a pest, often the flower damage is relatively heavy. This insect pest method is to pierce the mouthparts into the leaves and suck the sap, so that the chlorophyll is destroyed, and the leaves appear gray and yellow spots or patches, and the leaves are orange, fall off, and even fall light.

2) Chemical control should be applied to 4000-5000 times of mite danger (800-1000 pounds of water per bottle of 100 ml) uniform spray, 40% dicofol EC 1000 1500 times, 20% mite kill net wettable powder 2000 times, 15% pyridoxine EC 2000 times, 1 8% zitogenol EC 6000 8000 times, etc.

Spider mites, spray it with the kind of spray that sprays mosquitoes...

It's a red spider, that is.

Bai is a kind of mite that pests dripping water du Guanyin leaves. There are a lot of dao on the market that specializes in killing this version of the red spider medicine, but the right is not very safe, the few I planted are water-raised, and they have grown, and the leaves are yellow, you check the back of the leaf, is there a lot of small red dots like climbing, if there are a few drops of wind oil essence diluted, spray on the back of the leaf and the leaf surface, and then take a paper towel to moisten it and gently wipe it off every once in a while, spray it a few more times, and it can be killed in two or three days, but you should always check the leaf surface and the back of the leaf to see if there is a red spider. Mine didn't grow anymore, and the leaves didn't turn yellow anymore, but they were found late, and two died.

I hope your flowers are better and better. Hope this method can help you too.

The ** method of growing insects in the soil of dripping Guanyin is as follows:

There should be a lot of humus in the soil and it should be very moist, so the easiest way to do it is not to water it for a while.

73 grams of mite emulsifiable concentrate 2500 times can be sprayed, pay attention to the spraying should be uniform and thoughtful, especially pay attention to the back of the fine leaves.

As long as the concentration is not too large, there is no effect, it's okay, domestic flowers and plants with insects can be completely used with household insecticidal sprays.

It's okay, as long as the roots are not moth-eaten, after the weather warms up, keep the potting soil moist, apply some nitrogen fertilizer appropriately, grow quickly, basically will not have any effect, in addition, pay attention to it, this insect is not brought in the soil, if it is recommended that you replace the soil, afraid that there are eggs in the old soil.

This one should be a leaf mite.

Biocontrol. Biological control should avoid over-fertilization, especially nitrogen fertilizer. When nitrogen fertilizer is applied excessively, plants become more susceptible to leaf mites. Timely removal of weeds in greenhouses and outdoors can reduce the number of leaf mite host plants. Removing old leaves and residual leaves from plants is also a way to reduce the appearance of leaf mites.

Physical control. Physical control is an important measure to reduce the number of leaf mites by removing the plants that have been harmed before the leaf mites pupate. In addition, getting rid of the female insect that is incubating eggs is also a way to reduce the damage.

Chemical control. Chemical control can be used to deal with pests with insecticides, but this can make more and more leaf mites resistant to insecticides, making it more difficult to control pests later on. In fact, leaf mite larvae are very well controlled in leaves, so the use of insecticides should be minimized. For example, abatein, sinokill and so on are very effective against larvae, because these agents can enter the leaves to kill the larvae.

Pyrethroid insecticides such as permethrin and cypermethrin are effective against adults but not much against larvae. The frequency of insecticide use is affected by the current number of leaf mites and their growth cycle. In order to disturb the habits of leaf mites, insecticides can be sprayed in the morning when the female is laying eggs, although the severicide is effective against leaf mites, but it should be avoided as much as possible.

Thrips are usually found together with leaf mites, and the number of thrips can be seen to see how effective the pesticides are. In addition, neonicotinoid insecticides are effective against leaf mite species that have been found in greenhouses.

To be honest, the only thing that really works is the spray. There are many related drugs in the flower market, but there are many factors to consider, if there are elderly and children at home, it is best to put the plants in an isolated space to apply pesticides, and it is recommended to spray the plants at home at one time, so that it is possible to completely kill, and there is, don't expect to be killed at one spray, at least two or three times.
