What is the fleshy orange Monroe from the heart of the leaf?

Orange Monroe is a succulent plant of Lycopodium in Sedum, and a horticultural hybrid of Carola and Saussurea involucrata. Its leaves are thick, long spoon-shaped or round spoon-shaped, flat or slightly concave, the back is round, there is no obvious ridge line, the front end is sharp and the short tip is not obvious. The whole plant is covered with a thick layer of frost, which is a standard rosette shape, usually white and pink-blue, with sufficient temperature difference.

How is the orange Monroe fleshy, starting from the heart of the leaf? Personally, I think there are the following possibilities, and the subject can refer to the comparison!

1. exposure. Although the leaves of Orange Monroe have a thick frost and a high degree of sun resistance, if they are exposed to the sun under the condition of excessive water shortage or accumulated water in the leaf core, the leaf core will be sunburned or even directly dried up. Therefore, in the usual maintenance, if the leaves of orange Monroe are soft, it is necessary to replenish water in time, and it is not allowed to be exposed to the sun in a state of water shortage. After watering or getting wet, if there is moisture in the leaves, dry them in time to prevent the sun from burning the leaves through water droplets.

Treatment method: move the orange Monroe to a cool and ventilated place for maintenance to prevent the leaves from getting wet, and new buds will grow when the dry leaves are cleaned in the later stage; If the leaves show signs of infection, they should be beheaded in time to avoid the black rot of the stems and endanger the life of Orange Monroe.

2. Caused by insect pests. Summer is the peak of the outbreak of the butterfly. Although it usually starts with meaty meat without powder, it sometimes lays eggs on meaty meat with powder. If the subject finds that the leaf center of his orange Monroe is dry and piles of insect droppings can be seen around it, it is that the butterfly larvae are alive. Hurry to check which leaf has a hole, pull it out and break it, and you will find that there are so many bugs in it that you can crush it with one foot.

Treatment: add insect nets to the meat, or kill it manually. If you find eggs on the leaves, clean them up in time. In fact, the best way to prevent and control Hyphantria cunea is to sprinkle small purple medicine in the fleshy basin before the arrival of summer, and then water it to let the fleshy body absorb it. In this way, within three months, the fleshy body will produce a deadly toxin to insects. If the larvae and scale insects of Hyphantria cunea come to eat the fleshy body and die directly, the effect is very good.

3. Caused by disease. If orange Monroe is infected with bituminous coal disease, it may dry up from the leaves in the center of the leaves, because the pathogen infection is irregular. It may infect the bottom leaves first, or it may infect the leaves in the center of the leaves first. The more serious the infection, the faster the consumption of leaves, and the high incidence of bituminous coal disease is in summer, so the subjects must carefully check whether there are tiny black spots behind the leaves and petioles of Citrus Monroe. If so, it is infected with bituminous coal disease.

Treatment method: isolate immediately, then spray thoroughly with carbendazim or methyl topaz combined with mancozeb and chlorothalonil, and change the bactericide every five days. As long as the infection is not serious, continuous spraying for a period of time can curb the bacteria. However, it is important to note that only one of carbendazim and thiophanate methyl can be selected, because the alternate use of the two will produce antagonistic effect, and it is not allowed to expose to the sun after spraying, otherwise it will cause serious phytotoxicity and make the situation of orange Monroe more serious.
