How are orchids destroyed? Mesophyllum is a very stubborn pest, the shell of the insect body has a thick layer of wax, general pesticides are not very lethal to it. Moreover, the presence of mesophyllum on the leaves of orchids is multi-generational. Many times Lan you use drugs to kill the larvae of pests, but the adult insects avoid medicinal properties because of the "protective nails". Before long, you will find that there are many shell worms on the orchid leaves.
The mesozoan pattern of the same 4 generations of the same strain, like the one above, is difficult to work if only the drug is used at this time. The insecting period of the mesophyllite is mostly from May to July every year (taking the Yangtze River Basin as a geographical reference), and the breeding rate of pests is very fast, from the discovery of two or three pests to the above picture, it generally only takes about 10 days. There is no secret to the treatment of mesenchymals, as long as you follow these few steps, you can quickly eliminate the orchid-leaved mesophyllum.

Once the orchid leaves are found to have a shell worm, it needs to be dealt with immediately, and delaying the time will not only bring more damage to the orchid, but also the more pests, the more difficult it is to manage accordingly. The original mesozoans mostly appear in the state of adult worms, the color is white, and many times the mesozoan and white frost disease are confused, which will occur fundamental deviations when using drugs. One key point to remember: Mesozoans are living organisms that are active, while white frost is a germ that does not move.
<h1 class="pgc-h-arrow-right" > two, scratch</h1>
When a small number of mesophylls are found on orchid leaves, the first step is to scrape. Whatever medications are used later must be scraped off. Before scraping the insects, lay a layer of adhesive paper on the pot (wide transparent tape, the sticky side can be placed upwards), so that the scraped pests can be stuck and avoid leaving "remnants".
<h1 class= "pgc-h-arrow-right" > three, shear</h1>
If the insect infestation is already serious, and it is impossible to clean up by scraping alone, it is necessary to cut off the severe orchid leaves. The leaf pruning should be concentrated with the shear (so as to unify the incineration treatment), and the leaf carapace of the orchid seedling should be very carefully observed, especially some dry leaf carapace needs to be pruned at the same time (the dry dead leaf carapace is often the hidden place of pests).

All the above steps are done, and only then do you consider using drugs, which can do more with less. There are many drugs that can be used to kill mesozoans, and in the past, when mesozoans appeared in crops, most of them used some highly toxic pesticides, but it was obviously inappropriate for family orchids. Fortunately, there are also many special subdivisions of mesozoans in the agricultural market, and Lanyou can find drugs with the words "killing, fighting, and exterminating" to use, and the effect is mostly very good.
The above is only some of the views that the good farmer himself has experienced and seen, and the views may be one-sided and limited, only for Lan You's reference. If you have any other questions, please feel free to leave a comment in the comments section.
