How to deal with the mucus in the flow of rich trees? how to eliminate scale insects completely?

Rich tree, this is a lot of people like farming, how to raise something wrong, rich tree flow mucus how to deal with? How to completely eliminate scale insects:

Home potted rich tree exudate dewdrop-like mucus, there are small white spots, there are spots on the leaves, what is the reason for this?

The rich tree may be affected by insect pests, which are shell insects.

The prevention and control methods are as follows:

The main results are as follows: 1. The ratio of liquor to water is 1 ∶ 2, and the surface layer of basin soil is watered thoroughly when controlling insects. Scale insects begin to move when the room temperature is 7 ℃ in spring. It can be irrigated once in April, and then watered every half a month or so for 4 times in a row.

2. After soaking small cotton balls in vinegar with 50ml vinegar, gently wipe the damaged stems and leaves with wet cotton balls to wipe off the shell insects. This method is convenient and safe, which can not only achieve the purpose of disinfestation, but also make the damaged leaves return to green light.

3. Wipe the diseased plant gently and repeatedly with alcohol, which can get rid of the shell worm, and it will be very clean and thorough. For example, when you wipe the diseased leaves of orchids with alcohol, you can not only get rid of the scale insects, but also completely kill the larvae that cannot be seen clearly with the naked eye, and the harm of scale insects is rarely found in the second year.

4. During the incubation period, the larvae were sprayed with omethoate or dichlorvos once a week for 3 or 4 times in a row.

The reasons for the flow of mucus in the rich tree and the treatment methods are introduced here, it is still necessary to breed the rich tree of your own family well.

How to control scale insects in chestnut trees? Methods of controlling scale insects in chestnut trees

Scale insects are the least favorite pests of Chinese chestnut growers, so do you know how to control scale insects? Next, the editor will introduce the control methods of scale insects for you in detail.

Scale insects are the most important pest to damage chestnut trees, which absorb juice on the internal branches and leaves, weakening the trees, yellowing leaves and withering branches. The scale insects that damage chestnut trees are mainly cotton scale insects, which overwinter on branches and leaves in winter and multiply in large numbers after the temperature rises in spring, causing damage to branches and leaves. At present, Chinese chestnut has been harvested, which is the best time to control scale insects. At this time, the scale insects will be killed and extinct, the number of overwintering will be reduced, and the damage will be significantly reduced next spring.

Methods of controlling scale insects in chestnut trees:

After picking the fruit of the chestnut tree, clear the garden in time, remove all kinds of weeds, dead branches and fallen leaves around the chestnut tree, cut off the dry branches damaged by diseases and insect pests on the crown, bury them deeply or burn them out of the garden, and smear the cut mouth with healing and anti-corrosion film in time to protect the wound quickly, and then spray 500 times the liquid of the tree protection general in the crown. After an interval of 15 to 20 days, the canopy was sprayed with 0.8: 1 Baume of stone sulfur mixture + tree protection general water solution. Spray all the branches and leaves inside and outside the crown evenly, so that there are drops of water dripping down.

The most important thing for people who can completely kill scale insects and succulent plants is scale insects. Summer is the high incidence period of scale insects. Some flower friends may have found traces of scale insects. If not, of course it couldn't be better. If you find scale insects, there is no need to panic, succulent plants are more or less, or early or evening, there is a chance to break out scale insects, because scale insects are too powerful, not only harmful to succulent plants, but also the first of the three prickly sucking pests in landscaping (the other two are red spiders and aphids), harming a variety of plants, control is also the most difficult, another point, scale insects like a hidden environment, branches and leaves are too dense Conducive to its survival and reproduction, succulent plant leaves are not only too dense, it is simply too dense, it is normal to be targeted by scale insects. When you find scale insects, you don't need to think about cleaning them all at once. If you want to kill them, you may fall into the embarrassment of killing both insects and meat, and you may also be embarrassed by the shadow of Toxoplasma gondii, because scale insects are really difficult to kill. Scale insects reproduce a lot, there are few special drugs to control scale insects, and there may be eggs left in the soil, but don't be too depressed. Generally speaking, a small amount of residual scale insects do not have a serious effect on succulent plants. When you want to play with it, you will find that the scale bug can't stand playing with you several times, at least you can guarantee that everything you can see can be killed clean, but the scale bug doesn't learn a lesson. After a while, you want to have fun with your succulent plant again. In fact, scale insects are easy to kill when scale insects generally have 1-3 generations a year, and a few 4-5 generations. Before nymphs turn into adults, there is often an intermediate period, in which the appearance is dull, and some even stop feeding. This time is before and after the annual sting, and the second is from the end of May to the beginning of June. At this time, most nymphs hatch soon, the body surface has not yet secreted wax, and the shell has not been formed, so it is still easy to kill with drugs. Spray once every 7 days for 3 consecutive times. Early winter is the best time to kill insecticidal eggs. Spraying the whole plant with 1000 times of 40% speed or 2000 times of pure chlorpyrifos can basically ensure that scale species will not break out throughout the year. If you can seize these three opportunities, spraying can get twice the result with half the effort, how to play with dead scale insects? 1. Physical killing, with needles, toothpicks, tweezers, one by one, suitable for the harm is not very serious, in the stem part or the back of the leaves of some fat and large scale insects. Of course, I will never tell you that there are N cockroaches behind a cockroach. I will only tell you that for scale insects with relatively powerful species, a female lays thousands to thousands of eggs and has two or three generations a year, which is like playing. A small number of scale insects can be killed directly with needles, but it should be noted that scale insects are committed by gangs. There may be a lot of places you can't see. two。 Send it away, use a pneumatic spray can, or a tap sprinkler to spray water on the affected area, as long as the current intensity is strong enough, it can generally be washed quite clean. Can also be combined with the fourth method of spraying, with a very low concentration of liquid instead of tap water, a few did not spray away the larvae, will also be killed, because scale insects are mainly adults are more difficult to kill. But the drawback of this method is that the skin is easy to come into direct contact with the liquid. 3. Alcohol killing method, you can buy that kind of sterilized alcohol in the drugstore with a concentration of 75% or more, you can use a brush to dip an appropriate amount of alcohol and wipe the insect pests repeatedly, you can get rid of the scale insects, and can remove ten points clean and thoroughly, if the leaves are too dense, it is not easy to wipe, you can directly use alcohol to drench the seriously damaged leaf center, generally speaking, those who are drenched will die, after a few days. If it is found that alcohol continues to be used, it is suitable for a few succulent plants, scale insects have been rampant, and the centers of leaves have been densely covered with scale insects. 4. Spray, I personally think that the most effective is Guoguang scale must be treated, but also used to protect the god of flowers, quick attack (killing phosphorus), matrine and other so-called low-toxic insecticides, the feeling is not killed clean, Guoguang scale must be treated to their own advertising is a strong fumigation, infiltration, contact and stomach poison, can wear the wax shell of scale insects directly act on the insect, kill nymphs, adults, also have a good control effect on eggs. However, when I use Guoguang scale, there has been drug damage. It is suggested that it is a little lower than the minimum concentration when configuring the solution. If you are not sure how much the concentration is appropriate, you can first configure it in a small amount and test it with Hongzhiyu and Ji Yueyue. As long as they do not cause drug damage, other succulent plants generally will not have a problem. In addition, a small amount of alcohol can be added when configured, which can improve the control effect, especially for scale insects that have developed drug resistance, the time of spraying is recommended in the evening or evening to avoid drug injuries or burns caused by too strong light. 5. Burying the medicine, using the above method, can basically kill the visible scale insects, but most of the eggs of the scale insects are in the soil and climb up after hatching (so the succulent plants purchased from the greenhouse, the soil is best discarded. The roots are cleaned properly), and there are also root powder scale insects at the bottom of the roots. Burying medicine can strangle scale insects in the cradle and kill those invisible root mealybugs. If buried, carbofuran and Bayer small green drugs are good choices. Take carbofuran as an example, carbofuran has internal absorption, stomach poison, contact effect, strong poisoning ability, long residual period, fast effect, not afraid of Rain Water, low cost. It is worth noting that spraying and burying drugs must be harmful to the human body, especially carbofuran and Bayer small green drugs, which are banned in some countries. As mentioned above, a small number of scale insects actually do not have much impact on succulent plants, so you can make your own judgment with or without them. Scale insects in the later stage... Although there are many ways of spreading scale insects, sometimes a succulent body is densely covered with scale insects, and the succulent insects next to it are very few, or can not be seen, but it does not mean that it is safe. The above is the introduction to the killing of succulent plant scale insects. I hope you can get something!
