1. Rot disease

Rot is mainly caused by improper watering. Yushu likes a warm and dry environment, and it is easy to cause rot if it is too wet, so in the maintenance process, attention should be paid to watering, keeping the basin soil properly dry, and must not accumulate water and overheat.

When rot occurs, it should be pruned in time, and some of the healthy branches and leaves around it should also be trimmed off, then smear the diseased part with 50% thiram 500 times solution, and then put it in a place with good ventilation for maintenance.

2. Leaf spot

On the leaves where leaf spot disease mainly occurs, the air is too moist and the ventilation is not good. It is a high incidence period in the rainy season. The disease spot shows small brown spots at the initial stage, and the surrounding leaves fade green in the form of water immersion. In serious cases, the leaves appear black-brown mildew spots and even become mildew layers. If it is not treated in time, it is easy to infect the whole plant.

During the rainy season, 0.3% Bordeaux solution can be sprayed to the leaves every 15 days to prevent the disease. For the diseased plants, the diseased leaves should be removed in time, and then 0.5% Mel 1% Bordeaux solution should be sprayed.

3. Anthrax

Anthracnose also occurs on the leaves, showing a small macula in the early stage, and in severe cases, the leaf spots become dry and withered, and it also spreads to the petiole, losing the luster of the whole bead.

Anthracnose is mainly caused by poor ventilation and low plant resistance. It is necessary to move it to a place with good ventilation, increase the application of phosphorus and potassium fertilizer, and increase the resistance of the plant. In the early stage of the disease, 0.3% Bordeaux solution can be used to spray leaves.
