1. The main diseases of flower palm trees include black shank and anthrax. Pear seedlings and saplings are vulnerable to black smut. The lesions mainly appear on leaves, branches and pods, and spread very rapidly during the rainy season. In severe cases, the whole leaves are black, and the words cause the leaves to fall off a lot, which seriously affects the growth of the young trees. Control measures: Spray with chlorothalonil or 5% methyl thiophanate 500 times. Spray once every 7 days for a total of 2-3 times. Anthracnose occurs in the young leaves and young shoots of the pear, and on the leaves, round brown small lesions appear with small black spots on the leaves; the spots on the shoots appear black and gradually dry. Control measures: spray with chlorothalonil or 70% zinc, spray once every 7 days, a total of 2-3 times.
2. The main pests of the flower palm tree: the tumor chestnut, the aphid, the leaf beetle and so on. In the artificial young forest, there are many cases of the disease, and the damage rate is 40-50%. The saplings after the damage often cause wind or death. Prevention and control methods: Adults can shake trees to make them fall and kill. It can also be injected from the insect fL with a veterinary syringe at 90% trichlorfon or 50% phoxim 300-400 times in the larval stage. Then seal the orifice with slime. Young forest aphids and leaf beetles are mostly caused by summer. Control measures: 90% trichlorfon or dimethoate should be used to spray the canopy leaves.
