Pests and diseases

The main pests of Paulownia are the giant bag moth and the scarab beetle, while the diseases include anthracnose and black bean disease. The main harm caused by scarab beetles to Paulownia is that the larvae will bite the seedlings in early spring. The main method of prevention and control is to kill them manually or release poultry to eat them. Paulownia is most susceptible to damage by the giant bag moth, which can be controlled by using 3000-3200 times dichlorvos solution. To prevent and control anthracnose and black bean disease, mix copper sulfate and ammonium bicarbonate in a ratio of 1:10. After sealing for 24 hours, prepare a 200-fold solution and spray it on the seedlings, which is more effective.
