Reaction on the stem, there is a Fusarium wilt, caused by bacterial infection, this disease is not easy to detect at first, once found, it will be very serious. If it is found that the stem is crooked to one side, or there is wilting, it must have given birth to Fusarium wilt, and the disease can be removed with a knife. The boundary between the disease and the non-disease is very clear, and it can be broken off by hand. If the diseased area is less than 1/3 of the stem, you can apply a layer of chlorothalonil solution to the non-diseased area and keep it dry. Apply it again every 10 days, and you can basically recover after 20 days.

The most serious pest in Dishui Guanyin is the mite, commonly known as the red spider. Red spiders are generally born on the back of leaves.
