We often hear a lot of friends who like meat and meat react that the meat they grow, in the growth process suffered from the persecution of mesozoans, many meat friends are very troubled, today drunken flower network for everyone to introduce, succulents common pests and diseases, as well as the control of mesozoan insects.
Succulents are generally susceptible to leaf mites (commonly known as red spiders), shell worms, whiteflies, spinosaurs and other diseases and insect pests during the growth process. Only by eliminating these pests and diseases can the meat and flesh that we carefully maintain can grow better.
Control methods of mesozoans:
The body of the mesozoan is wrapped in a layer of cuticle carapace, which is not effective if sprayed directly with drugs. It is like a lice that sucks human blood, sucking up the sap of the plant, thus causing great harm to the flowers and trees, the affected plants not only grow poorly, but also appear yellowing of leaves, early leaf fall and other phenomena, which will seriously make the plant wither and die. The flowers that were victimized were Milan, jasmine, camellia, and laughter.
There are four main prevention and control methods:
Strengthened phytosanitary: In natural conditions, mesozoans are less active, have limited self-propagation and diffusion capabilities, and have certain limitations in distribution. However, with the development of production, the exchange and transportation of flowers are frequent, and the opportunities for man-made and long-distance transmission of pests and diseases are increasing. Quarantine work stipulates that flowers can only be transported without dangerous diseases and insects (including various propagating materials). If diseases and insects are found, various effective measures should be taken to eliminate them and prevent further spread.
Artificial control: In the process of cultivating flowers, it is found that there are individual branches or leaves with shell insects, which can be gently brushed off with a soft brush, or combined with pruning, and cut off insect branches and insect leaves. It is required to be brushed, cut clean, and burned centrally, and do not throw it away.
Medicinal control: Spray the nymphs during the peak of the nymphs, depending on the various occurrences of the mesozoans. Therefore, most nymphs hatched for a long time, the body surface has not yet secreted wax, the shell has not yet formed, and it is still easy to kill with medication. Spray once every 7-10 days, 2-3 times continuously. It can be sprayed with 40% oxidized 1000 times liquid, or 50% malathion 1500 times liquid, or 255 imino thiophos 1000 times liquid, or 50% dichlorvos 1000 times liquid, or 2.5% cypermethrin 3000 times liquid. You can also buy that kind of disinfectant alcohol in the pharmacy, the concentration is 75% or more, with a brush dipped in the appropriate amount of alcohol after repeatedly wiping the insect infestation site, you can get rid of the insect shell, and can be removed very cleanly, thoroughly, if the leaves are too dense, not easy to wipe, you can directly use alcohol to shower the seriously damaged leaf heart parts, generally speaking, the drizzle will die, after a few days of rubbing, if you still find that alcohol is used, suitable for a few succulents, the shell insects have been flooded, and the leaf hearts have been densely packed with insects.
Protection and use of natural enemies: such as australian ladybugs that prey on blowing sponges, big red ladybirds, golden aphid wasps that parasitize shield aphids, soft aphid wasps, red dot lip ladybirds, etc. are effective natural enemies, which can be used to control the harm of mesenchymal insects and should be reasonably protected and utilized.
Prevention and control methods:
(1) Mix white wine with water in a ratio of 1:2. When treating insects, water the surface of the potting soil. Mesozoans begin to move at room temperature of 7 °C in the spring. It can be watered once in april, and then every half a month or so, and the effect is seen for 4 consecutive times.
(2) Use 50 ml of vinegar (rice vinegar), put the small cotton ball into the vinegar and soak it, and gently rub it on the stems and leaves of the affected flowers and trees with the wet cotton ball, you can shake off the shell worm and kill it. This method is convenient and safe, which can not only achieve the purpose of pest control, but also make the damaged leaves return to green and shiny.
(3) Gently and repeatedly wiping the diseased plant with alcohol can remove the mesenchymal insects, and they can be removed very cleanly and thoroughly. If you wipe the orchid diseased leaves with alcohol, not only can you get rid of the mesozoites, 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 be harmful to the mesozoites, this method is simple, safe, and the effect is good.
(4) Use diesel, washing powder, water according to the ratio of 10:0.6:6 into the mother liquor, at this time the mother liquor contains 60%, milky, diluted with water containing 30% oil, after diluting the oil containing 30% of the liquid, carefully spray on milan, kumquat, cycad shell worm. After a week, most of the mesozoans changed from fresh orange to dry state, indicating that this method has a good control effect on mesozoans.
Finally, Drunken Flower Network will popularize other knowledge of the shell worm to everyone:
Mesozoan hazards generally have the following characteristics:
1. Morphological degradation, pectoral foot degradation or complete disappearance, generally except for the hatching of the larvae have the ability to move, other insect states once fixed will no longer move, lifelong in one place to feed;
2. Can secrete wax to cover the insect body, form a variety of mesembranous shells, with the increase of insect age, the shell thickens, drugs are generally difficult to reach the insect body;
3. Large reproduction, such as the large jade-pointed insect shell insect laying thousands of eggs per female insect; the white wax cystic worm lays thousands of eggs per female insect; the blowing cotton bug occurs 4 to 5 generations a year; the sugar flake shield shell insect can be harmful for many years;
4. After the damage of the tick shell insects, it can induce plant bituminous coal disease;
5. Some unfavorable environments for plant growth lead to a decrease in plant growth momentum, which is conducive to the occurrence of scale insects.
