Improper handling of the three major diseases of Magnolia liliiflora can affect human health

As a premium member of the Magnoliaceae family, Magnolia liliiflora has a traditional cultivation history of more than two thousand years in China, is renowned overseas and deeply loved by Chinese people. Magnolia liliiflora is listed in the IUCN Red List of Plants. Its medicinal value is relatively precious, and its bark, leaves and flower buds can all be used as medicine. After special processing, its flower buds can also treat symptoms such as headache, waist pain, brain pain and rhinitis, while its bark can paralyze motor nerve endings and has an obvious analgesic effect.

But the nobility of Magnolia liliiflora has also attracted these three major diseases: chlorosis, gray mold and rot. The first symptom of chlorosis is a decrease in chlorophyll, and gradually the entire leaf turns yellow, then gradually turns white. The first symptom of gray mold is that in a humid environment, a conspicuous gray mold layer forms on the diseased part. Rot, commonly known as root rot, causes branches, trunks and leaves to rot along with it. Its causes come from various aspects, and only early detection allows early treatment.

1. How to prevent and control chlorosis?

Chlorosis is a manifestation of a physiological disease of the plant. Soil that is too sticky, a pH value exceeding the standard, and an insufficient supply of iron elements can all cause chlorosis. We can use a 0.2% ferrous sulfate solution to drench the roots of the affected Magnolia liliiflora, and can also use a 0.1% ferrous sulfate solution to spray the leaves of Magnolia liliiflora. What is even more noteworthy is to periodically apply an appropriate amount of farmyard manure to supplement the nutritional elements that Magnolia liliiflora needs.

2. How to prevent and control gray mold?

In seasons with a lot of rain, it is necessary to avoid rain in time and cultivate on an indoor balcony, improve the humidity of the environment, reduce the probability of gray mold occurrence, understand the patterns of gray mold occurrence, do a good job in disease prevention, and regularly spray special agents such as diethofencarb to eliminate fungal infection at the germination stage. After diethofencarb enters the fungal cells, it binds with the tubulin of the fungal cells, inhibits the division of fungal cells, and eliminates the disease from the root. Spray continuously 2 to 3 times to consolidate the control effect and protect the plant's good growth.

3. How to prevent rot?

Fertilization and soil are key. Control the amount and apply more organic fertilizer. Nitrogen fertilizer and phosphorus-potassium fertilizer are very necessary, and increasing the air permeability of the soil is important. Conventional treatment methods include scraping off the diseased spots and applying medicine on time, cutting off infected branches and burning them in a concentrated manner. In addition, preventing the invasion of pests and diseases is also very important. Spray two-hundred-fold Bordeaux mixture on the trunk to form a protective film on the plant surface, thereby sterilizing and disinfecting. Children with weak constitutions must never touch the above pathogens, as they have a certain effect on the respiratory tract and can very easily lead to colds, coughs and so on.
