2. Precautions for growing Radermachera sinica

Pest and disease control:

1. Leaf spot disease: in environments with high temperature, high humidity, and poor ventilation, its leaves are prone to leaf spot disease. So how do we prevent and control it? We need to strengthen ventilation and light transmission in the indoor environment, evaporate the standing water on the leaves, immediately remove diseased leaves once found, and regularly spray 50% carbendazim wettable powder at 600 times dilution. Continue three to four times, with half a month between each application.

2. Scale insects: high temperature, high humidity, and a poorly ventilated environment are the best conditions for scale insects to reproduce, so we need to provide ventilation, air permeability, and light, and not water too much, which would cause excessive humidity. When live scale insects are found, they can be wiped off with a damp cloth. For large-scale cultivation, corresponding pesticides need to be used for spraying and killing.

3. Mites: the main damage symptoms are new leaves becoming wrinkled and leaf surfaces curling and deforming. Corresponding acaricides can be used.
